Shanghai hydraulic press manufacturer: what should I do if the hydraulic press does not maintain pressure?
by：WORLD
2022-11-18
A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or rocking motion). It is simple in structure and reliable in work. When it is used to complete the reciprocating motion, the deceleration equipment can be omitted, and there is no transmission gap, and the movement is stable, so it is widely used in the hydraulic system of various machines. When the hydraulic press needs maintenance during the period of time, if the hydraulic cylinder or valve leaks, it will cause pressure leakage without maintaining pressure. This situation will bring unnecessary trouble to the actual production, and in severe cases, the quality of the product will be degraded. It will form a situation that the hydraulic press does not maintain pressure. If this phenomenon is found in the ordinary process, it should be handled according to the following points:
1. The leakage of various control valves does not hold pressure.
2. The pressure holding time is too long, resulting in no pressure holding.
Solution: Because the pressure holding time is too long, there is a lack of hydraulic oil, which is not enough to supply pressure. In response to this problem, the method of uninterrupted oil replenishment can be selected. During the pressure maintenance process, the pressure needs to be maintained according to the leakage condition of the pressure of the supplementary system.
3. The pressure is not maintained due to leakage inside and outside the hydraulic cylinder.
Solution: Solve the problem from the bottom up. This situation requires improved cooperation between the hydraulic cylinder bore, piston and piston rod, and manufacturing accuracy. Only when the accuracy meets the requirements, can the problem of non-holding pressure caused by internal and external leakage be effectively reduced.

1. The leakage of various control valves does not hold pressure.
Solution: To solve this problem, it is necessary to improve the machining accuracy and cooperation accuracy of the valve body to solve this problem. In addition, pay attention to the structure of the valve body, which can effectively improve the sealing performance and reliability in use. necessary precautions.

Solution: Because the pressure holding time is too long, there is a lack of hydraulic oil, which is not enough to supply pressure. In response to this problem, the method of uninterrupted oil replenishment can be selected.
