Servo hydraulic press temperature is too high harm

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 moving parts such as the slide valve will become thinner and produce greater friction resistance, resulting in increased wear and affect the normal operation of the machine.

2, the temperature of the equipment is too high, so that its own thermal deformation, the different moving parts of the hydraulic components in the heat expansion degree will be different because the gap between them is smaller at the same time and produce stuck, thus reducing the work efficiency of the servo hydraulic press.

3, the high temperature causes the life of the hydraulic oil to be greatly reduced, blocking the gap in the middle of the small hole, resulting in the pressure valve can not work normally.

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 oil air separation pressure, resulting in the hydraulic system performance reduction.
