Introduction to the matters needing attention when using oil cylinder of hydraulic press

Before we use the hydraulic oil cylinder, we must make a series of preparations, the first is to make the hydraulic circuit pressure relief. Otherwise, when connected to the cylinder, the tubing connector will be loosened. The high pressure oil in the loop will eject. So we need to decompress the hydraulic circuit first. Then the following small series to connect the use of oil pressure cylinder need to pay attention to matters.

1, in order to prohibit the piston rod and other slender parts bending or deformation, the use of cushion wood support balance when placed. When disassembling, check the thread of the piston rod, the thread of the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc.


2, disassembly should be carried out in order.


3, before and after unloading, try not to let the parts of the hydraulic cylinder be polluted by the surrounding dust and impurities.


4, the cylinder should be carefully checked after removal to see which parts can continue to be used, which parts can be repaired and reused, and which parts need to be replaced.


5, the parts must be carefully cleaned before assembly.


6. The corresponding wrench should be used when the threaded connection is tightened, and the torque should meet the standard requirements.


7. After the piston and piston rod are assembled, it is necessary to try to measure whether there is a difference in coaxiality and straightness on the full length.


8. After assembly, there should be no blocking sensation and uneven resistance when the piston component moves.


9. When the hydraulic cylinder of the hydraulic press is installed on the main machine, the sealing ring must be added between the inlet and outlet joints and be fastened.
