Tips for Selecting and Sizing Pneumatic and Hydraulic Components

Blog | July 14th, 2022

Hydraulic and pneumatic systems provide the principal form of power for the majority of cylinders, tools, and even certain drive systems in the modern production plant that is characteristic of today’s world. They can be used in high-temperature as well as high-radiation industrial situations, both of which are conditions in which the majority of electronic instruments will not perform correctly. There are large volumes of literature available on the appropriate design of systems, the appropriate size of components, the design of circuits, valve and control technology, and other design issues. On the other hand, here are some pointers that you won’t necessarily discover in the textbooks:

 Pressure Versus Flow

Working with pneumatics necessitates an understanding of pressure and flow. The operators will often increase the pressure to compensate for the decreased flow. The use of supply lines that are far larger than necessary is, in most cases, the most effective technique to ensure that a process is supplied with the appropriate volume of air.

Electric Actuators Should Be Used

Given the increasing cost of energy, designers may want to think about deploying energy-efficient electric movement. This is subject to the condition that the application requirements fall within the performance capabilities of an electric actuator, however. In only the past five to ten years, this technology has seen many advancements that, among other things, have resulted in more accurate movement and even more complicated controls that are built directly into the gadget itself.

Valve Size Matters

It is possible to enhance pneumatic systems by ensuring that all of the components are of the appropriate size. This consists of the pipe as well as the valves. The size of the valve is a very important consideration. If the flow capacity is too low, there is a possibility that the production cycle would be negatively affected. If you want to reduce the amount of time spent producing and boost product quality, getting the sizing right is essential.

Select Valves With Three Opening Positions

When there will be employees near the action, it is better to have a valve that has three positions than one that just has two. Because of this, it is essential to have a valve that can be set to one of three positions in case of an emergency. On the other hand, the action will be completed with a 2-position valve before the valve is turned off.

Internally-Controlled Flow

When using a pneumatic cylinder in a project, especially in applications with a high cycle count, choose a fitting that comes equipped with a flow control valve already installed in it.

Select Only High-Quality Tubing

To stop leaks in machines, polythene (PE) tubing and push-on fittings should be replaced with nylon tubing instead. In a plant environment, it is difficult to locate soft tubing leaks since they are difficult to notice. This makes the process challenging.

Steel Tubing, Steel Pipes, And Hydraulic Hoses Must Have The Correct Internal Diameter

When evaluating aircraft hydraulic system components, piping should be sized to reduce pressure decreases. When the flow is unstable, it generates friction between the fluid and the pipe walls, resulting in wasted energy and an increase in fluid temperature as a result. This is because of turbulence and unanticipated pressure dips caused by high fluid velocity. Pump intake conditions can be regulated to limit the likelihood of excessive heat in aviation hydraulic system components by maintaining a reasonable fluid velocity.
