Precautions When Adjusting the Pressure of Hydraulic Press MachineUpdate：2022-09-20 Hits：223
The pressure adjustment of the hydraulic press machine should be operated by professionals, and untrained personnel should not adjust it at will, so as not to damage the equipment.
Before adjustment, it is necessary to understand the characteristics of the raw materials and the molding size. After strict calculation, it is necessary to obtain the appropriateness of the equipment pressure adjustment.
When adjusting the pressure, the working pressure of the system shall not be higher than the rated pressure. Once it is higher than the system pressure, the hydraulic system will be damaged, oil leakage or hydraulic components will be damaged later.
The actual pressure of the hydraulic pump of the hydraulic press machine depends on the size of the load, which cannot be adjusted;By reducing the pressure of the relief valve, the neutral position of the throttle valve reversing valve, etc., the outlet of the pump is blocked, and the pressure of the relief valve and the outlet of the pump is dispatched until the demand value stops.
After the pressure of hydraulic press machine is adjusted, manually test whether the pressure can suppress the raw material and whether it can meet the requirements, and then lock the pressure handle.
After adjusting the pressure of the hydraulic press machine for a period of time, check whether there is oil leakage in the hydraulic system of the 1000-ton hydraulic press. The noise or instability is abnormal.
