How Flow Control Systems Operate Within an Air Cylinder - 1/23/2017

To understand how to flow is controlled within an air cylinder, you must first understand the air cylinder and the compressed air within it. First of all, air cylinders, pneumatic cylinders and, occasionally, pneumatic actuators, are industrial machines that use compressed air to power various manufacturing processes. Compressed air can be defined as explosive, inflammable gas that travels quickly from a high-pressure chamber to a low atmospheric pressure area. This is all brought about rapidly by a position shift of the air valve, the release of air or gas through said air valve and the resulting movement of the cylinder piston and/or rod.

With this knowledge in hand, it is easy to understand that airflow, piston and rod speeds all must be measured and controlled for a safe and successful process. Since fast-moving rods are difficult to measure, one way that technicians measure airflow is through the installation of mechanisms known as air flow controller systems. They’re usually installed in air lines between the valve and cylinder, in the cylinder port and the exhaust port. Talk to your supplier to find out whether or not it’s necessary for you to install a system in the exhaust port. Note that when you introduce an airflow controller system into your cylinder, you need to observe cylinder control reaction time.

A second way to regulate cylinder airflow is through a needle bypass, a feature of some cylinder flow control systems that allows air to pass through a needle that controls airflow.

Similar to the needle bypass is the needle valve, which controls airflow inside and outside the cylinder. While this method can drastically reduce airflow, it may also cause an issue with energy or heat transfer within your process equipment.

To get the most out of your flow control systems, aka a full air supply, optimal cylinder speed, smooth piston movement and minimal waste, make sure that they’re properly installed. You can do this by checking schematics along the side of your control systems, which offer flow paths to direct installation. Follow these guidelines, and you’ll be in business in no time!

How to Reduce the Repair and Replacement Costs of Hydraulic Cylinders - 12/21/2016

Many modern industrial machines, such as pumps and motors, are run on energy generated by hydraulic cylinders. Hydraulic cylinders, while a great source of energy, can be costly to repair and maintain. Research finds that one in ten industrial machines do not operate at optimal levels because of specific design factors, design factors that can be avoided by making sure your machine and its energy source match your production and capacity requirements. With a mismatched machine, you will find yourself impacted by the stressors of repair and replacement, driving up costs for yourself and your customers.

Contain these costs by performing regularly scheduled maintenance. Meticulous and timely maintenance is the only way to strengthen the efficiency and durability of your industrial equipment. However, in this effort, do not handle your machines roughly. Careful handling is incredibly important. Read on for tips on machine handling that will reduce your expenses during maintenance.

Look for Twisted Rods

Air cylinder rod twists are undesirable abnormalities associated with poor construction and low quality materials. Twists may also be a sign of incorrect cylinder or rod installation or unsuitable rod diameter. Bent rods contribute to deficient load balancing, which in turn may lead to additional issues, such as leakage and unpredictable application performance downtime.

For these reasons, it’s important to check that rods and cylinders are mounted properly, per the instructions of your hydraulic cylinder provider.

Check Rod Quality

In addition to the quality discussed above, the rod’s finish quality must also be noted. To work seamlessly with its application, a rod needs superior finishing. Superior finishing is neither overly smooth nor overly rough, and it should complement the object for which it is being used. To prolong the life and increase the durability of a rod, some specialists recommend alternating its coating or finishing.

Finally note that a wearing area will cause seal warping if it doesn’t have enough load bearing support. To avoid this and subsequent adverse impact, carefully select your bearing or wearing area.

How to Select the Most Efficient Industrial Air Cylinder - 12/6/2016

Commonly called pneumatic cylinders, air cylinders use engineering and mechanical principles to generate force and movement. Said force and movement are compelled by compressed, high-pressure air that is then converted into kinetic energy for the consumption of a machine motor. This energy source regulates the production and performance of process equipment. To maintain regulation, attain machine speed goals and high quality processes, you must employ a machine that is appropriate for your application. For best results, consider the following points when selecting your next air cylinder.

1. Cylinder Type: Before you select what type of air cylinder works best for you, think about the conditions in which and the application with which it will be used. Don’t hesitate to ask questions and get input from your supplier. Cylinder types include: reusable, non-reusable or repairable, NFPA, rod-based, metal cylinders and more.

2. Diameter of the rotation or movement: Take into consideration the size of your object as well as the size within the cylinder. Also, make sure that the diameter of the cylinder rod is as long as or longer than the space taken up by your object’s movement.

3. Machine Weight: Another important element to consider during the selection process is the weight of the machine that will encase the air cylinder. Because it consumes energy released by the cylinder, this machine’s performance depends on pressure from compressed air. Consequently, your motor, specifically the starter motor, should be paired with a compression cylinder that is 75% of its weight.

4. Correct Cylinder Installation: Finally, to ensure the safety and efficiency that comes with proper installation, make sure your supplier offers installation services. Cylinder installation procedures are based on size and type, and they frequently have integrated design options meant to make installation easier. Such options include: threaded holes for tightening bolts, mount, rod-cap thread, rear-cap, rear tang and the like.

Understanding the Different Types of Air Cylinders - 11/17/2016

Also known as gas-driven cylinders, air cylinders are appliances that enliven industrial machines, aided by the linear motion of energy/force generated by compressed air/gas. Some air cylinders that are also considered pneumatic cylinders, from the Greek pneuma, for air, are very similar to hydraulic cylinders, both applying kinetic energy for movement using pistons. Pneumatic cylinders, however are a much safer alternative to hydraulic cylinders because they are much less likely to have fluid or gas leaks, and perform much more reliably. There are many types of air cylinders, meeting many industry and application specifications. See below for details on frequently used air cylinders (rotary, single piston, double-action, telescoping, rodless and high-pressure) and their functions.

Rotary Cylinders

A rotary cylinder is a motor with a rotary, or a rotating piston, that rotates on the unit’s outer border in either circular or semi-circular motions.

Single Piston Cylinder

Single, or straight-line, piston cylinders are the most commonly used type of air cylinders. They are activated by a piston pushed by energy created by compressed air. To reset the cylinder piston, a spring draws it back into place. From there, the same energy pushes the piston forward again to continue the process.

Double-Action Cylinder

A double-action cylinder uses the same functioning principles as single piston cylinders, but instead of using a spring to return the piston to neutral, it uses the force generated by airflow. Because double-action cylinders deliver piston transfers back and forth with such ease, it is not necessary for airflow or gas to flow inward.

Telescoping Cylinders

A type of motor that can work in both single and double-action cylinders is the telescoping air cylinder. A motor with (somewhat expensive) advanced technology, it can be set in accordance with individual application specifications.

Rodless Cylinders

A rodless cylinder circumvents the need for a rod or piston through the independent movement of the cylinder itself, and, depending on your application, it can be programmed to work like a single or double-action cylinder unit.

High-Pressure Air Cylinders

Finally, we come to the most power air cylinder, the high-pressure air cylinder. These customizable air cylinders can perform extensive tasks while taking up very little, because they are so small and efficiently designed.

Where Small Hydraulic Cylinders Are Used - 8/30/2016

Although hydraulic cylinders are used in large, heavy duty machines and industrial equipment, the same technology is also employed in much smaller applications. We may be used to thinking of hydraulic cylinders as powerful lifting tools (which they can be) but sometimes they are used for very small and basic operations. The interesting thing about small hydraulic cylinders is that they operate on the very same principles as large ones, but the size of the cylinder and the piston limits the strength, making it possible to manufacture cylinders for literally hundreds of different uses based on the necessary force.

One very common example of this is found in the trunk of almost every car. It’s usually two small hydraulic cylinders fixed to the frame that allow someone smoothly open and close the trunk without it falling. The pressure of someone pushing down on the door is enough to compress the cylinders, but they are strong enough that the trunk won’t slam shut when it is left open. The diameter of these particular cylinders is less than an inch, but they exert all the force that is necessary for their function.

Specialized technology companies who are in the process of developing and manufacturing robotic equipment often use small hydraulic cylinders to add greater functionality to their units. On a small moving robot, miniature hydraulic cylinders can power legs that lift the unit up and down or move it from side to side in some fashion. For a stationary piece of robotic machinery, hydraulic cylinders can be very good at accomplishing linear movement if and when necessary. Although hydraulic technology is not new or complex like some emerging technology, it is still highly useful for advanced equipment that is currently being developed. You can imagine that small hydraulic cylinders could even be useful in drone technology as companies continue to explore the functional possibilities of drones.

At Cylinders & Valves Inc., we offer cylinders of all sizes for a wide variety of industrial clients. From small hydraulic cylinders to large heavy duty ones, we can provide you with whatever you need for your equipment.

Hydraulic Cylinders And Their Many Applications - 8/15/2016

In the 21st century, hydraulic cylinders can be found in the machinery of almost any industry. Because a hydraulic cylinder can create so much power, it can be utilized for many different purposes and ultimately make almost any job much easier and more efficient. Variations of hydraulic technology have been used for centuries. In fact, way back in 1648 it was the French physicist Blaise Pascal who observed that pressure exerted on confined fluid is transmitted equally throughout the fluid and creates a unified force. This would later become known as Pascal’s Law. While this realization was still far away from the invention of hydraulic cylinders as we know them today, it was foundational to our understand of pressurized fluid and its amazing capabilities.

Today you don’t have to look far to see hydraulic cylinders being used for processes that would be almost impossible to accomplish otherwise. Think about backhoes on construction sites, for example. Imagine how difficult it would be to dig holes and move tons of dirt of a backhoes didn’t exist? It’s a series of hydraulic cylinders in the backhoe that gives it such tremendous lifting capabilities. Imagine how quickly a large backhoe can dig out the foundation for a new home or office building. Or what about snow removal equipment? You’ve probably noticed large plow trucks driving down the highway in the winter to clear the roads. Many of these have a plow on the front that can be raised and lowered right to the ground because of the hydraulic cylinders that they are connected to. And then there’s the waste management industry! Hydraulic cylinders make it possible for garbage trucks to dump material, and for compactors to crush material into a more compact form. Without these tools, waste removal would be a much more difficult process.

At Cylinders & Valves Inc., we’re proud to provide hydraulic cylinders to so many important industries so that they can keep up with their important work. We’re a family-owned business with professional service that can’t be beat. If you need hydraulic cylinders or valves, contact us today to request a quote!

How A Double Acting Cylinder Works - 7/28/2016

A double acting cylinder is one of the most basic forms of a hydraulic cylinder. The piston rod is caused to retract when pressurized fluid is directed into the end of the rod. In a similar way, when pressurized fluid is released into the cap end, the piston extends. During either retraction or expansion, fluid is flowing out of the opposite end and back into the hydraulic reservoir of the mechanism. Generally speaking, expansion always requires more force than retraction, so the piston can be retracted more quickly than it can be expanded.

So what applications should a double acting cylinder be used in? Machines like forklifts, tractors and construction equipment use double acting cylinders to generate the necessary force for lifting heavy objects using a pressurized hydraulic flow. The result is the ability for the pistons to steadily lift heavy loads, and they can also lower them in a steady and controlled manner, usually at a faster rate. Because of their efficient use of force and hydraulic fluid, double acting cylinders are one of the most commonly used cylinders in an industrial machinery. If you have a double acting cylinder from Cylinders & Valves Inc., you can be sure that it is built to last. Not only that, but we make all of our parts so that they are easy to service and replace.

An Introduction to Back to Back Cylinders - 7/7/2016

A back to back cylinder setup is created by combining two cylinders with the same bore size. Both cylinders operate with the same tie rods, creating a four piston cylinder. Various cylinders can be selected for different stroke lengths. Back to back cylinders use standard materials and parts, but they can be fully customized to meet the output needs of a specific application. Because the parts used to construct back to back cylinders are standard pieces, these cylinders are easy to repair and service, and they are not as expensive as other configurations. At Cylinders & Valves Inc., we use a non-corrosive brass construction on all of our cylinders to maximize their durability.

Our series BC and TBC back to back cylinders are designed specifically for pneumatic and hydraulic applications. Sizes and dimensions vary, and threaded rods are standard but non-threaded rods can be provided upon request. Both rods operate simultaneously through a single center input port.

Hydraulic Cylinders in Cranes - 12/3/2015

Luffing cranes are a type of industrial crane that is used in the construction industry and in the shipbuilding process. These luffing jib cranes or level-luffing cranes are made to operate within compact quarters, they are most commonly found at a construction site in an urban setting where there is not a lot of room to work. The crane is designed to move the crane arm up and down, and makes sure that the crane arm does not swing from side to side as this is dangerous in close quarters and can be against some building regulations.

Just looking at these, you might think that there is a complex design involved, when in reality the overall process is relatively simple one and the design consists of two metal arms that are connected to a wire, this wire is what pulls the arm up and down. Now, there are updated designs that utilizes hydraulic cylinders in place of these wires which results in a bit of a different design but the overall application of the crane is the same.

For hydraulic cylinder designs, a counter weight is used on one end of the arm and the hydraulic cylinder extends and retracts the arm up or down in a quick manner, it can go from horizontally to almost vertical in about 90 seconds, which is much quicker than the previous wire designs. The hydraulic cylinders that are used must be able to bear significant weight as the crane arms can be quite heavy themselves and with the added weight of whatever they might be carrying, if they hydraulic cylinder fails it puts everyone around the crane at risk.

Hydraulic Cylinders in Car Jacks - 11/19/2015

A car jack is a tool that just about everyone knows how to use, or at least should know how to use if you operate a vehicle. They allow for us it lifts our incredibly heavy cars in order to change a flat tire or work on our cars in other ways. Hydraulic Cylinders are the reason these tools are able to lift such a heavy object while being so small.

Back in the day car jacks were screw jacks, which were far more complicated to use and now have mostly been replaced by hydraulic cylinder car jacks. These jacks are made up of six different parts, a reservoir, pump, main cylinders, valve, check, release valve and piston.

The hydraulic fluid is kept in the reservoir, the pump draws the fluid out and through the check valve. Once the fluid is in the main cylinder, the piston is forced up into the cylinder as it fills with liquid. The release value is opened in order to release the pressure and returns the piston back to the original position.

The force that is created is enough to lift the car, allowing for the car jack to be useful. They function off of Pascal’s Principle, this principle states that pressure is the same at all points inside a closed container. This principle is what allows these small hydraulic car jacks to lift cars that are far greater in weight and size.

Getting to Know Hydraulic Cylinders - 11/4/2015

Hydraulic systems are used in a variety of systems and machines, and the hydraulic cylinder is one of the key parts within this system. A hydraulic cylinder is not simply a cylinder as it consists of a barrel, cylinder head, cylinder cap, piston rod and the piston itself. Hydraulic cylinders are made from a number of different materials depending on the application from nickel, chromium, or stainless steel. These stainless steel hydraulic cylinders are especially useful when the cylinder is used in a highly corrosive environment.

The piston rod is found inside the barrel of the cylinder where it attaches to the machine or product that is being moved. The cylinder head closes off the top of the barrel while the bottom is sealed off by the cap. Pressurized fluid is used to give the cylinder force, in order to control this fluid a control valve is used and connected to the distributor hoses and tubes.

In order to categorize hydraulic cylinders, the barrel is often looked at. There are two main categories of hydraulic cylinders, tie rod and welded body cylinders. The tie rod cylinders have steel rods on the outside in order to provide reinforcement to the barrel. Welded body cylinders have a solid body construction that provides support. Hydraulic cylinders can be found in a wide range of applications from wood splitters and construction machines to roller coaster restraints and car engines.

Hydraulic Double Acting Cylinders - 10/13/2015

Hydraulic cylinders are used in a variety of machines in assisting pushing and pulling mechanics. Take a construction excavator for example; hydraulic cylinders are incredibly important in the operation of this machine. Hydraulic cylinders can be found in a wide range of industries such as automotive, construction, oil and gas, power generation, material handling, and many others. Hydraulic cylinders are split into two main categories, single acting cylinders and double acting cylinders. Each has their own unique function, and both are capable of producing a large amount of work force no matter their size or application.

Double acting cylinders are able to provide the standard pushing and pulling forces that hydraulic cylinders are known for, but they are also able to turn, steer, lift and tilt. While a majority of their parts come in the shape of a cylinder, often time they are available in other shapes such as rectangles or custom designed shapes for particular machines. The hydraulic fluid is released from an enclosed area which produces pressure that allows the piston to move based on the amount of fluid in the enclosed area at any given time.

Uses for Mini Air Cylinders - 9/28/2015

Mini air cylinders work in the same way larger air cylinders function, they are just smaller. Air cylinders have a number of different uses across a wide range of industries, mini air cylinders are also found in use in the same industries just in smaller applications. Here are some uses for mini air cylinders:

Hydraulic Systems: Mini air cylinders are able to move hydraulic fluid from one area to another which keeps the system functioning properly. These cylinders also move oil, water, synthetic liquids and other liquid mixes around in a system.

Pneumatic Devices: Pneumatic air cylinders have similar properties, but have a slight difference to hydraulic systems. These devices work with lighter loads and lower pressure systems than compared to what the hydraulic systems deal with. This means that pneumatic air cylinders are perfect for fast operating speeds; this means they have a much higher level of control than hydraulic air cylinders.

Power Transmission: Similar to a spring-loaded machine, the air cylinders that are in a power transmission will take the power that is stored inside the cylinder and use it to power a device. These machines are in rotary devices, holding devices, and linear motion devices. Smaller linear motion devices often contain mini cylinders.

Fluid Control: The flow of fluid in a device is something that the air cylinders can control along with the airflow inside a device. Mini air cylinders are really effective at this because they are big enough to move the fluid or air yet do not weigh the actual unit down. These cylinders act like control valves for fluid and air by controlling both the direction of the flow and the pressure.

Highlighting Small Hydraulic Cylinders - 9/15/2015

Hydraulic cylinders are a vital part in heavy manufacturing equipment as they manage the movements and activities of the machine and its attachments and linkages. In order to get the desired results these parts are made up of variety of components to get the job done such as: cylinder barrel, cylinder head, piston rod, piston, seals, cushion, cylinder base connection, rod gland, and cylinder base.

While there may be many parts involved in hydraulic cylinders, small hydraulic cylinders are often called upon for many jobs. These jobs are typically less intense so do not require the strength of a standard hydraulic cylinder. Yet they do require all of the same components found in the standard sized version. A lot of times the size of hydraulic cylinders is dependent on the size of the machine itself, hydraulic cylinders can be made in just about any shape or size, whether large or small. Hydraulic cylinders work together with the other functions of the machine in order to make the process an overall smooth operation.

Hydraulic Cylinders are often found in robotics, military, automotive, trash removal, oil, gas, and many other industries.

Hydraulic Cylinders put to use on Aircraft Carriers - 8/28/2015

Often referred to as the cities of the sea, aircraft carriers can hold upwards of five thousand people at once for months at a time. There are 21 active super carriers and the United States owns 11 of them. Now you might be wondering why am I reading about aircraft carriers on this blog, but it turns out hydraulic cylinders play a vital role in the function of these great ships.

The majority of bombers and fighter jets can only travel short distances so aircraft carriers are necessary as a mobile command center for these planes to land and refuel. The biggest issue is that while these ships are massive they still do not have enough runway room for a jet to take off and land. This is why landing on an aircraft carrier is considered one of the most difficult tasks a pilot can perform. However, the use of hydraulic cylinders makes landing and taking off possible on these aircraft carriers.

Seeing as the runways are too short for standard take off procedures, carriers use a catapult system to launch planes up to proper take off speed. Each catapult consists of two cylinders that are filled with steam from the ship’s reactor by the catapult officer. This Wile E. Coyote technique makes up for the shorter runway space and helps the pilot accelerate to the right speed and avoid plunging into the ocean with the very expensive plane.

Now that we covered taking off from the aircraft carrier, we will look at the more complicated half of utilizing an aircraft carrier, landing on it. The process of landing involves a lot of communication between the pilot and the crew on the carrier. Once the pilot receives the go ahead they must line the plane up with the deck and hook their plane on one of four wires that span across the deck using a hook at the back of the plane. These cables are connected to hydraulic cylinders below the deck that absorb the planes energy allowing the plane to come to a full stop. They are necessary because the pilot is required to accelerate while landing in so if they miss the wire they have enough speed to take off again.

Mighty Air Cylinder - 6/25/2015

Size makes a difference when it comes to air cylinders, the size of the air cylinder makes a difference in the areas where the air cylinder can be used. The way an air cylinder is made up of a tube or cylinder that contains a plunger. This plunger is pushed forward to force air out of the cylinder in order to control certain devices such as air brakes or other similar applications that utilize air in their process. Air cylinders are commonly found in two different types, double acting and single acting. Not only do they come in different types, they also can be found in a number of different sizes. This fluctuation in size allows consumers to purchase an air cylinder that will work in their application, for example compact air cylinders are able to fit into tight spaces where other air cylinders might not work like in the back of a garbage truck.

Air cylinders are all over, chances are you will be able to find them in the room you are sitting in. Typically, storm doors or even a screen doors are controlled by a small, compact air cylinder that helps to control the speed at which the door closes. The plunger can be adjusted to get the desired rate of speed in which the door will close. Air cylinders help prevent heavy doors from slamming shut or closing too fast and resulting in injury to the individual who attempted to walk through the doorway.

While they may be small, these compact air cylinders can pack quite the punch. They come in a variety of types so you can get the right pounds per square inch pressure required for your individual application. Picking the right air cylinder for your unique needs is important for your application to operate properly.

The Many Benefits of Customized Cylinders - 7/20/2015

Although air cylinders are available in several stock sizes and shapes, there are still several benefits to buying custom air cylinders. Custom air cylinders enable precise configurations and distinctive uses that are not available with stock air cylinder shapes and sizes. Several air cylinder suppliers give customers the choice of making custom-made air cylinders. This boosts their business and helps give the clients what they want.

Customized air cylinders are ideal for times where stock cylinders won't work. An industrial plant will usually produce a wide range of cylinder shapes and sizes that may work with all OEM components and devices. Typically, industrial plants will redesign the cylinder to maximize performance speed and power to make each cylinder the most efficient for its application.

Typically, the client will create a design and provide specs to the air cylinder manufacturer, who will take the blue prints and model them into an identical cylinder. After the client receives their part, they will then assemble the new part with the machine to check the performance of the cylinder. If changes are necessary, the client will then send the new plans to the cylinder manufacturer, who will then rebuild the cylinder with the new changes. The part may go back and forth between the customer and the manufacturer several times before the air cylinder is accepted. Once the final design is approved, the manufacturer will build as many custom cylinders that the client requires.

Air Cylinder Options - 6/25/2015

Size matters for many things in life, including air cylinders. There are different applications for each type and size of air cylinder, allowing for a diverse range of cylinder choices. Although air cylinder manufacturers supply a diverse range of cylinders, their construction is pretty basic. The most common version of an air cylinder consists of a tube or cylinder with a plunger inside. This plunger moves up and down within the tube pushing air pressure out. This pressure or forced air is used to control devices, such as brakes. In addition to size and pressure range, air cylinders are also manufactured in two different varieties—single-acting and double-acting. Cylinder sizes range from compact cylinders to larger industrial size cylinders.

Compact air cylinders are perfect for use in small areas of a machine where there is not a lot of room for a large air cylinder like you might see on the back of a garbage truck compactor. Compact air cylinders can often be found in your household. If you have a storm or screen door, you may notice a cylinder towards the bottom of the door that controls how fast the door closes. By adjusting the cylinder, you change the rate at which the plunger forces air out of the cylinder, thereby affecting how quickly the door closes.

Various ranges of pressure are specified for each type of compact air cylinders. This pressure is measured in pounds per square inch of pressure or PSI. If you are looking to purchase an air cylinder, you will need to determine the amount of psi, the size, the type, and what application it will be used in. If you have questions on your next air cylinder purchase, contact Cylinders & Valves for answers!

What Makes up a Solenoid Valve - 6/3/2015

A solenoid valve is made up of a variety of small intricate parts that work together to make sure that the solenoid valve is functioning properly. While solenoid valves come in a variety of different voltages and cover a wide range of uses. All solenoid valves function in the same way and all are made up of the same twelve parts.

Body: The body of a solenoid valve is commonly made from water-resistant metal and encases the rest of the parts.

Inlet Port: The inlet port is exactly that, the place where water enters the solenoid valve.

Solenoid: The solenoid itself is a tightly wound coil that will twist to move the plunger up and down. This movement forces water in and out of the valve.

Coil Windings: Coil windings work to keep the solenoid coil function without causing damage to itself due to constant tightening and releasing.

Lead Wires: These wires power the valve, without them the valve would receive no electrical power and would not function properly.

Plunger: The plunger is controlled by the wire and moves up and down in an effort to control the flow of water.

Orifice: This is the exit point of the water from the solenoid.

Outlet Port: The opposite of the inlet port, it is here the water is released from the solenoid valve.

All of these different parts come together to make a solenoid valve. Because these parts function together so well it is easy to control the flow of liquid without dealing with complicated machinery.

The Many Types of Pneumatic Cylinders - 3/16/2015

There are tons of different kinds of pneumatic cylinders. Each is designed for specific applications and uses. Some are more complex, while others are simpler. This makes pneumatic cylinders useful for many different situations. Some common types of pneumatic cylinders include:

Single-acting cylinders: These cylinders utilize compressed air to create motion in a single direction and depend on other mechanisms to return the piston in the opposite direction. They are typically used for simpler tasks that require smaller forces.

Double-acting cylinders: This type of cylinder allows compressed air to work on both sides of the cylinder. Unlike the single-acting cylinder, this type utilizes the compressed air to move a piston along an axis in both directions.

Through rod air cylinders: The piston in this cylinder type extends through both sides of the cylinder. With the piston extending all the way through the cylinder, the forces and speeds on both sides of the cylinder are equal.

Tandem air cylinder: As its name suggests, this cylinder is actually two cylinders placed in series. The two cylinders work together to supply twice the force of a single cylinder.

Telescoping cylinder: This more complicated cylinder is comprised of many nested hollow stages. When the piston rod is set in motion, the nested cylinders and rod expand, or telescope, out in segments. This cylinder can be single or double-acting.

The majority of pneumatic cylinders utilize a piston rod, but this is not always a necessary component. Without a piston rod, force can be transferred using magnetic or mechanical means. There are many different kinds of cylinders, and they are made from many different materials as well. Materials like steel, brass, and aluminum are all commonly used in fabricating pneumatic cylinders. These varying materials can help make cylinders better suited to particular environments, temperatures, and applications.

Why 3-Way Solenoid Valves are Cost-Effective - 3/5/2015

If you are looking to keep costs down, the 3-way solenoid valve utilizes a simplistic design for complex processes and offers low maintenance costs. Because the 3 way valve design requires fewer moving parts, it is considered to be most cost effective since fewer parts require less replacement costs. Although the design is simplistic, its functionality is complex by providing vital functions for liquid or gas processing systems.

A solenoid valve consists of a magnetic solenoid coil that activates by way of electrical charges to produce current flow; an actuator that activates from the coil’s current and allows the valve to open; and lastly a valve that opens when activated and closes in order to block a substance from flowing through the canal. In some valve designs, the solenoid coil is absent and the valve operates by way of pressure.

Specifically, 3-way solenoid valves are designed to allow liquids or gases to flow into several different ports. Part of the solenoids operation is to have its ports free flowing. Potentially, a port can be blocked causing maintenance issues. Since the design is simplistic, the maintenance should be as well. All in all, the 3-way solenoid valve offers a virtually maintenance free, cost-efficient, and vital operation for medical & research facilities, food & beverage companies, the automotive industry and cleaning systems.

Hydraulics: A Greener Power Source - 2/9/2015

Many initiatives and campaigns are constantly in the search for "green" techniques and "environmentally friendly" products. There is a hope to see these new methods and products available to all industries, including hydraulics. Hydraulics in general, are becoming more popular for their ability to be a more environmentally friendly method of powering items from cars to machinery. So having hydraulics, such as hydraulic valves, to become a part of any industrial processes seems like a good way to becoming green.

There are variations of hydraulic parts that have been gaining momentum in the recent years such as hydraulic engines, hydraulic motors, hydraulic pumps and hydraulic cylinders. Typically, most of these items (if not hydraulic) are run off of gasoline or electricity, but hydraulic parts are able to function through the use of hydraulic fluid. Through the use of hydraulics, companies can decrease their carbon footprint. Even the automotive industry uses hydraulic parts to help a car function, along with the gasoline used to run the engine.

We all know that saving the planet is no easy task, and while it is not going to happen overnight, it is the small steps of consumers and producers, as well as innovators that will help us get on a road to recovery. Who knew that by using hydraulics, we can start to make the Earth a little cleaner, a day at a time.

Rotary Air Cylinder Operations - 1/5/2015

The two main types of rotary air cylinders are linear air piston cylinders and rotary vane air cylinders. Rotary air cylinders are powered by pneumatic or hydraulic power and move air using a rotary motion. Both types of rotary air cylinders operate with similar principles and operate best in fluid-like conditions, making them also known as fluid power actuators.

Linear air piston cylinders use a linear piston and a gear system to create the air rotation. Most often, these cylinders are used in dry applications, such as radios. While linear air piston cylinders are used in dry conditions, rotating vane cylinders are most often used in liquid applications. These rotating air cylinders have a rotating asymmetrical vane that swings through a cylinder with two different radii. Having asymmetrical sides, the pressure on one side of the vane is different from the other, creating an unbalanced force. This unbalanced force produces a rotating motion.

Rotating pressure in these air cylinders make them ideal for opening and closing (rotation) for different applications such as the operation of large air core gauges, windshield wipers, opening pipes and process valves, and the opening and closing of gates and dams.
