PNEUMATIC CYLINDER

The pneumatic cylinder (or air cylinder) is the most common type of pneumatic actuator, widely used in automated production equipment, construction, mining and other fields. The pneumatic cylinder is mainly composed of a cylinder body, a piston and a rod. Unlike hydraulic cylinders, the fluid in pneumatic cylinders is compressed air (will not cause any pollution and safety risks to the working environment). The pneumatic cylinder can convert the pressure energy in the compressed air into mechanical energy to perform a certain movement.

According to the working principle, pneumatic cylinders can be divided into single-acting pneumatic cylinders and double-acting pneumatic cylinders. The single-acting pneumatic cylinder has only one air port for compressed air to enter the cylinder to push the piston to move; when compressed air is not needed, the internal spring will push the piston of the cylinder back to its original position. The double-acting pneumatic cylinder has two air ports, which can push the piston to a specified position by adjusting the compressed air at both ends.

According to the size, cylinders can be divided into standard cylinders, mini cylinders and thin cylinders. Their volume, maximum stroke, application field, etc. are all different, and they need to be selected according to the actual situation.

According to the number of rods, the pneumatic cylinders can be divided into single-rod pneumatic cylinders, dual-rod pneumatic cylinder and triple-rod pneumatic cylinders. The greater the number of rods, the greater the driving force that the cylinder can provide. Precautions).

Of course, there are also some special cylinders, such as linear slide pneumatic cylinders, pneumatic gripper, rotating pneumatic cylinders and so on. The linear slide pneumatic cylinders has very high accuracy and can withstand a certain torque, and is widely used in automated production equipment. The pneumatic gripper is cylinder that can perform grabbing actions. The rotating pneumatic cylinder is a cylinder that can perform a rotating action.
