1. The body temperature of the servo hydraulic press itself is too high, so that the viscosity of the oil is reduced, the leakage is increased, the efficiency of the system and the bulk efficiency of the pump will be reduced, and the oil film of the sliding valve and other moving parts is thinner and produces greater friction resistance, resulting in intensified wear and affect the normal operation of the machine.
2, the temperature of the equipment is too high, so that its own thermal deformation, different moving parts of the hydraulic components in different degrees of thermal expansion will be stuck because of the gap between them at the same time smaller, so reduce the working efficiency of the servo hydraulic press.
3, the high temperature leads to the life of hydraulic oil is greatly reduced, blocking the gap in the middle of the hole, resulting in the pressure valve can not work properly.
4, the temperature rise is too high to cause the rubber seal deformation, accelerate the aging degree, resulting in leakage.
5, the temperature is too high to reduce the air separation pressure of oil, resulting in the performance of the hydraulic system.
Therefore, we should check and adjust the servo hydraulic press according to its different load requirements. Also use the appropriate hydraulic oil, such as the viscosity of oil, if you can choose a lower viscosity, but also improve the movement conditions, so as to reduce the loss caused by friction, can also be very good to reduce load and heat. Of course, the accuracy of hydraulic components and hydraulic systems should be enhanced.
