How should the hydraulic cylinders be disassembled when problems arise?
Apr 27, 2017

The first is that the hydraulic circuit should be unloaded, otherwise when the hydraulic cylinder joints of the tubing loose, the circuit in the low-pressure oil will be agile spray out. Hydraulic circuit unloading should be first loosen the relief valve, such as the handwheel or pressure regulator screws, pressure oil unloading, and then cut off the power supply or cut off energy sources, so that hydraulic installation stalled.

1, before and after unloading to try to invent conditions to avoid the hydraulic cylinder parts are surrounded by dust and impurities purification. For example, the demolition should be carried out in a clean environment as far as possible; all parts after demolition are covered with plastic sheeting, do not use cotton cloth or the rest of the task to cover up.

2, pipe machine to avoid the piston rod and other slender twists or deformation, use cushion wood support balance. Remove the piston rod to avoid injury to the top screw thread, oil mouth thread and piston rod appearance, cylinder liner inside the wall.

3, the demolition of the parts must be carefully cleaned.

4, the hydraulic cylinder after the demolition should be careful review, to confirm which parts can inherit the use, which parts can be repaired and then reuse, which parts must be changed.

5, demolition should be in order. Because the structure and size of various hydraulic cylinders are not identical, the disassembly order is slightly different. Individual should be put off the oil cylinder of Chongqing two cavities, and then remove the cylinder head, finally remove the piston and piston rod. When dismantling the cylinder head of the hydraulic cylinder, the Kari or rings about the inner-card bonding are used to prevent the use of a flat shovel, and the flange-type end cap must be made with screws, not to hammer or pry. When the piston and piston rod is difficult to extract, cannot be forcibly typed, should first identify the cause and then disassembly.
