How to solve the abnormal pressure of hydraulic press

by:WORLD     2022-09-28
1. The resistance hole is blocked: For the overflow valve of the hydraulic press, the pressure is often lost after the system is pressurized, the pressure cannot be adjusted by rotating the handwheel, or the system is overpressured, and the overflow valve does not function as an overflow. For the pressure reducing valve of the hydraulic press, the pressure of the oil outlet does not rise, and the oil flow is very small. The main reason is that the contamination of the oil causes the orifice to be blocked by the dirt, and the spool valve loses control.








2. The spool of the main valve is too tight or blocked by dirt: the adjustment pressure of the relief valve of the hydraulic press rises, or the pressure reducing effect of the pressure reducing valve fails.





3. The spring is broken, missing, or the spring stiffness is not suitable, which causes the spool valve of the hydraulic press to lose the function of the spring force and cannot be adjusted. Or the stiffness of the spring is too large or too small, making it difficult to adjust the pressure.








4. The oil inlet and outlet of the hydraulic press are installed reversely, and it is easy to reverse the installation on the pipe connection. The plate valve is also easy to install the oil circuit reversely in the design of the manifold, resulting in the failure of pressure regulation.



5. Leakage: The external leakage of the hydraulic press will cause environmental pollution, which is easy to find; while the internal leakage occurs mainly due to the machining accuracy, assembly accuracy or wear and tear, and it is not easy to check, which often leads to increased noise of the hydraulic press valve and significant pressure fluctuations.
