Hydraulic cylinder manufacturers next began to disassemble hydraulic cylinders:
First, in order to prevent the bending or deformation of slender parts such as piston rods, the cushion support should be balanced when placed. When disassembling, damage to the top thread of the piston rod, the oil port thread and the surface of the piston rod, the inner wall of the cylinder liner, etc. should be prevented.
Second, disassembly should be carried out in order. Due to the different structure and size of various hydraulic cylinders, the disassembly order is also slightly different. Generally, the oil in the two chambers of the cylinder should be discharged, then the cylinder head should be removed, and finally the piston and piston rod should be disassembled. When disassembling the cylinder head of the hydraulic cylinder, special tools should be used for the snap key or ring of the internal snap key connection, and it is forbidden to use a flat shovel; For flanged end caps must be ejected with screws, no hammering or hard pry is allowed. When the piston and piston rod are difficult to withdraw, they should not be forcibly punched, and the cause should be ascertained before disassembly.
Third, try to create conditions before and after unloading to prevent the parts of the hydraulic cylinder from being contaminated by surrounding dust and impurities. For example, disassembly should be carried out in a clean environment as much as possible; After disassembly, all parts should be covered with plastic sheeting, not cotton cloth or other work cloth.
Fourth, hydraulic cylinder manufacturers should carefully inspect the cylinder after disassembly to determine which parts can continue to be used, which parts can be repaired and then used, and which parts must be replaced.
Fifth, each part must be carefully cleaned before assembly.
