Although the structure of the rotary oil cylinder is small, its effect is very large. When repairing or maintaining the rotating oil cylinder, it is sometimes necessary to disassemble the rotating oil cylinder. In order not to affect the use of the rotating oil cylinder, the following issues will be introduced for everyone.
1. Before removing the hydraulic cylinder, the oil pressure drop in the hydraulic cylinder circuit should be zero.
2. When disassembling, prevent damage to the parts of the hydraulic cylinder.
3. Because the specific structure of hydraulic cylinders is not the same, the disassembly order is not the same, it is necessary to judge according to the specific situation.
For flange connection type, the flange connection screw should be removed first, and the end cover should be ejected with the screw. Do not pry or hammer it hard to avoid damage. For the inner card key connection, use a special tool to push the guide sleeve inward to expose it. After the key is locked, remove the key and fill the key groove with nylon or rubber material, and then dismantle it outwards; for screw-connected oil cylinders, the screw gland should be unscrewed first; when removing the piston rod and piston, do not rigid To pull the piston rod assembly out of the cylinder, try to keep the axis of the piston rod assembly and the cylinder slowly pulled out in a line.
4. After the parts are dismantled and inspected, the parts should be stored in a relatively clean environment, and an isolation device to prevent bumps should be installed. Before reassembly, the parts should be cleaned.
The above is the introduction of the precautions for the disassembly and assembly of the rotating oil cylinder, and I hope to help you.
