Hydraulic cylinder is the actuator of hydraulic system, its function is to convert hydraulic energy into mechanical energy. The hydraulic cylinder input is the liquid flow and pressure, the output is linear speed and force. Saao hydraulic pump accessories hydraulic cylinder piston can complete reciprocating linear motion, the output of a limited linear displacement. The hydraulic cylinder is composed of cylinder 1, piston 2, piston rod 3, end cover 4, piston rod seal 5 and other main components. 6 is the inlet and outlet of oil.

1v continuously moves to the right, and the piston rod does work on the outside. On the contrary, when the pressure oil is input into the right chamber, the piston moves to the left with the speed of 2v, and the piston rod of savo accessories also does work to the outside world. In this way, a reciprocating motion is completed. This hydraulic cylinder is called a cylinder cylinder fixed cylinder. If the piston rod is fixed and the left cavity continuously inputs pressure oil, the cylinder cylinder moves to the left. When the pressure oil is continuously flowing into the right chamber, the cylinder moves to the right. This kind of hydraulic cylinder is called piston rod fixing cylinder.
