disassemble Hydraulic cylinder Before that, the hydraulic circuit should be depressurized, otherwise, when the oil pipe joint connected with the oil cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.

As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, then remove the cylinder head, and then remove the piston and piston rod. During disassembly Hydraulic cylinder When installing the cylinder head, special tools shall be used for the snap key or snap ring connected by the internal snap key, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, it shall not be forced out. The reason shall be found out before disassembly.

How to disassemble the oil cylinder will not pollute the oil cylinder. When disassembling, we should carefully check how the accessories can continue to be used without replacing them. If they need to be replaced, they should be replaced. Let's learn about it together with interested partners!    

1. Before disassembling the hydraulic cylinder, depressurize the hydraulic circuit. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device.

2. Do not damage the piston rod thread, oil port thread, piston rod surface, cylinder liner inner wall, etc. during disassembly.

3. Disassemble in sequence. As the structure and size of hydraulic cylinders are different, the disassembly sequence is slightly different. It is prohibited to use flat shovel; The flange end cover shall be pushed out with screws, and hammering or hard prying is not allowed.  

4. Do not allow the accessories of the hydraulic cylinder to be polluted by the surrounding dust and impurities before and after disassembly.
