Precautions when disassembling hydraulic cylinder

 

(1) When removing, prevent damage to the top thread of the piston rod, the port thread and the surface of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the elongated members such as the piston rod from being bent or deformed, the spacer support is applied to balance.

 

(2) Disassemble in order. Due to the different structure and size of the various hydraulic cylinders, the disassembly sequence is slightly different. Generally, the oil in the two chambers of the cylinder should be drained, then the cylinder head should be removed, and finally the piston of the cylinder and the piston rod of the cylinder should be removed. When disassembling the cylinder head of the hydraulic cylinder, special tools should be used for the key or the snap ring of the inner card type connection. It is forbidden to use the flat shovel; for the flange type end cover, it must be screwed out, no hammering or hard smashing is allowed. . When the piston and the piston rod are difficult to extract, do not force it out. You should first find out the cause and then disassemble it.

 

(3) Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being contaminated by dust and impurities around. For example, when disassembling, try to carry out in a clean environment; after disassembly, all parts should be covered with plastic cloth, not covered with cotton cloth or other work cloth.
