1. Disassembly Engineering hydraulic cylinder The hydraulic circuit should be depressurized before. Otherwise, when the oil pipe adjacent to the oil cylinder is loosened, the high-pressure oil in the circuit will be ejected quickly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, then cut off the power supply or cut off the power source to interrupt the operation of the hydraulic device.

2. During disassembly, prevent damage to the thread at the top of the piston rod, the rib of the oil port, the outside of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from being straightened or deformed, the skid support is used for misalignment during layout.

3. The assembly shall be developed by times. Because of various projects Hydraulic cylinder The mechanism and size are different, and the assembly procedure is slightly different. As usual, the oil in the two chambers of the oil cylinder should be drained, and then the cylinder head should be assembled, and the piston and piston rod should be assembled at the end. When assembling the cylinder head of the hydraulic cylinder, special tools shall be used for the internal bayonet type adjacent bayonet or snap ring to prevent the use of a flat shovel; The flange end cover must be pushed out with screws. Hammering or hard prying is not approved. If it is difficult to draw out the piston and piston rod, the notice shall be found out before assembly.

4. When unloading, we should try to create conditions to prevent the parts of the engineering hydraulic cylinder from being infected by the dust and impurities on all sides. For example, disassembly should only be carried out under clean conditions; After assembly, all parts shall be covered with plastic cloth, not covered with cotton cloth or other industrial chemicals.

5. After the engineering hydraulic cylinder is assembled, it is necessary to be responsible for the search to determine which complete machines may continue to be used, which ones may be reused after general repair, and which ones must be changed.
