Cylinder pneumatic components, cylinder pneumatic circuit schematic diagram

Pneumatic cylinder is a very important driving method in pneumatics. Pneumatic cylinders convert energy stored in compressed air into motion. Different types of pneumatic cylinders are filled with gases such as carbon dioxide or connected with air to other pneumatic equipment to perform required functions. This article will mainly introduce knowledge related to the working principle of pneumatic cylinders.









Many industrial applications require linear motion during their operating sequences. The main function of the pneumatic cylinder is to convert air pressure into mechanical energy, and it can do both linear motion and reciprocating motion. The gas is compressed in the pneumatic cylinder of the compressor to increase the pressure. Pneumatic cylinder consists of dust ring, end cover, piston, piston rod and seals.

In pneumatic pneumatic cylinders are used as actuators in the pneumatic system. So it is called pneumatic linear actuator. Choosing the right pneumatic cylinder ensures the long-term success of your application and improves the overall performance of your operating equipment.








How pneumatic cylinders work


The working principle of a pneumatic cylinder is to convert the potential energy of compressed air into the mechanical energy of exerting force or the kinetic energy of motion. Within a pneumatic cylinder, two chambers maintain different air pressures. A piston (sometimes called a rod) attached to the dividing wall begins to move as the volume of the chamber changes in response to the relative pressure of the two chambers. At least one chamber is connected to a port that allows air to flow into and out of the pneumatic cylinder.





A pneumatic cylinder is a motor that relies on a working fluid, a piston working principle, and reciprocating motion. Pneumatic cylinders are used in a wide range of applications. For example, hydraulic motor drives are used in forging presses, lifts, pumps, construction and machine building, where powerful motors are required. It guides the piston to make linear reciprocating motion in the pneumatic cylinder. The air changes thermal energy into mechanical energy through the expansion in the pneumatic cylinder. The gas is compressed by the piston in the compressor pneumatic cylinder to increase the pressure.

Pneumatic cylinder, also known as pneumatic actuator, is an important component of pneumatic or compressed air control mechanical device. An air or pneumatic cylinder is a device that converts compressed air power into mechanical energy. The incredible force exerted by pneumatic cylinders is due to the simple mechanical principle of pressure exerted on the surface area of ​​the piston.






Characteristics of pneumatic cylinders


There are many different types of pneumatic cylinders such as single-acting cylinders, double-acting cylinders, rotary pneumatic cylinders, rodless pneumatic cylinders and telescopic cylinders. These pneumatic cylinders are preferred for many reasons, including noiseless operation and eliminating the need to store fluid, as is the case with hydraulic cylinders. The pneumatic cylinder is also clean and environmentally friendly as any leakage from it will not pollute the surrounding environment. Moreover, they are very efficient in performing different functions, which is why most people prefer to use them.

These devices have a simple working principle and therefore are very convenient to use. Stored gas or air consists of potential energy, which is converted into kinetic energy under the force of compression. Compressed gas or air will always try to expand, forcing the device's piston to move with very great force. This force from pressurized gas actually forms the basis of pneumatic tool operation. A simpler device that utilizes this working principle is a pneumatic cylinder.






Different air chambers will have different operating specifications. Two key characteristics are the pneumatic cylinder stroke, the distance between the fully extended and fully retracted piston positions, and the operating pressure range. The pressure range reflects the smaller amount of pressure required to drive a pneumatic cylinder and the larger pressure it can safely withstand, and determines the amount and nature of work a pneumatic cylinder can perform. Another important feature is the device’s mounting options, which will ultimately determine how the pneumatic cylinder is integrated into a larger mechanical system.
