2. To prevent the hydraulic cylinder parts from being damaged during disassembly.
3. Because the specific structure of the hydraulic cylinder is different, the disassembly sequence is different, and it should be judged according to the specific situation.
When connecting flanges, remove the flange connecting screws first, and push out the end cover with screws. Do not pry or hammer hard to avoid damage. For internal key connection, the guide sleeve should be pushed inward with special tool. After the key is exposed, take out the key and fill the key slot with nylon or rubber material before disassembly. Firstly, unscrew the threaded gland of the threaded cylinder; When disassembling the piston rod and piston, the piston rod assembly should not be pulled out of the cylinder, but the axes of the piston rod assembly and the cylinder should be kept in a straight line and pulled out slowly.
4. After the parts are disassembled and inspected, the parts should be kept in a clean environment, and isolation devices to prevent bumping should be installed. Clean the parts before reassembly.
