How can the servo Hydraulic Press fail to keep up with the oil pressure? Why is the oil pressure too low? what reason? How to deal with the low oil pressure of a servo hydraulic machine, now the editor will answer the following questions for you:
When the engine throttle is fully opened, the inlet oil pressure of the torque converter is less than the standard value. The reasons for this phenomenon are as follows: the oil supply is low, and the oil is lower than the oil suction surface. Oil pipe is leaking or blocked; too much oil flows into the transmission; oil pipe or oil filter is inserted; the hydraulic pump is severely worn or damaged; the oil suction network is installed incorrectly, how can the hydraulic pressure not keep up with the oil pressure and oil bubbles; the inlet pressure valve cannot be closed Or the spring stiffness decreases.
How does the hydraulic press fail to keep up with the oil pressure? The low pressure solution of the four-column hydraulic press is too low: check the oil level first. If the oil level is lower than the minimum value, oil should be refilled. If the oil level is normal, check the inlet and outlet pipes. If there is an oil leak, it should be eliminated. If the inlet and outlet pipes are well sealed, the performance of the inlet and outlet pressure valves should be monitored. When the inlet and outlet pressure valves are not closed, they should be disassembled to check for cracks or scars on the parts, whether the oil holes are clear, and the spring stiffness is small. Solved in time. If the pressure valve is normal, the hydraulic machine should remove the tubing or screen check. If there is a blockage, clean up and remove the sediment. Treatment method of low oil pressure of servo hydraulic machine
If the oil pipe needs to be checked, replace the hydraulic oil pump if necessary. If the hydraulic oil foams, check the oil return pipe installation. If the oil level of the oil return pipe is lower than the oil level in the oil sump, put the sleeper back into the oil pipe.
