Engineering machinery Hydraulic cylinder Disassembly steps are as follows:
1. Before removing the hydraulic cylinder, depressurize the hydraulic circuit.
2. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, the high-pressure oil in the circuit will be ejected.
3. When the hydraulic circuit is depressurized, loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil,
4. Then cut off the power supply or power source to stop the hydraulic device.
5. During disassembly, do not damage the piston rod thread, oil port thread, piston rod surface, cylinder liner inner wall, etc.
6. In order to prevent the piston rod and other slender parts from bending or deformation, they should be evenly supported by skids.
