At present, a hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the effective area; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffering device and an exhaust device. The damping device and the exhaust device are determined according to specific application occasions, and other devices are necessary.

The hydraulic cylinder is an actuating element in a hydraulic transmission system and is an energy conversion device for converting hydraulic energy into mechanical energy.
