What are the reasons and solutions for the hydraulic pressure of a 200-ton four-column hydraulic press not keeping up?

The manifestation of the oil pressure not keeping up is that when the engine throttle is opened, the oil pressure of the torque converter is less than the standard value.

Reasons: The oil supply is small, the oil level is lower than the water level of the inlet, oil leakage or oil pipe blockage; too much oil flows to the transmission; oil pipe or filter blockage; severe wear or damage and damage of the hydraulic pump; the oil suction net device is not suitable; when the hydraulic press shows that the oil pressure cannot keep up, the oil will foam; at this time, the inlet and outlet pressure valves cannot be closed, or the tension of the spring is reduced.

Solution: First check the oil level. If the engine oil level is below the standard scale, engine oil should be added; if the engine oil level is normal, the engine oil PIPE should be checked and whether the engine oil pipe is leaking. If there is a leak, it should be cleared. If the seals of the inlet and outlet pipes are not good, the operating status of the inlet and outlet pressure valves should be checked. If the inlet and outlet pressure valves cannot be closed, they should be disassembled to see whether the parts are broken or broken, whether the oil holes are unblocked, and whether the spring tension is small.
