The principle of a hydraulic cylinder is a device that converts hydraulic energy into mechanical energy. Its working principle is based on Pascal's principle, which states that pressure is uniformly distributed in a fluid. The input of a hydraulic cylinder is the flow rate and pressure of the liquid, and the output is the speed and force of linear motion. A hydraulic cylinder mainly consists of a cylinder barrel, a piston, a piston rod and a sealing device. It can achieve reciprocating linear motion and is widely used in mechanical equipment.
