How to reduce the working speed of servo hydraulic press

1, hydraulic pump output oil flow is small, low pressure.

Solution: To solve the problem of small output flow and low output pressure of hydraulic pump.

2, the oil temperature increases, the oil viscosity decreases, the leakage is added, and the energy flow is reduced.

Solution: Control the oil temperature.

3. The hydraulic system planning of the servo hydraulic press is unreasonable, and when the load changes, the flow into the hydraulic performance component also changes accordingly, resulting in a decrease in the speed of the performance component.

Solution: reasonable planning of the hydraulic system, so that the system flow does not change with the pressure.

4, the oil is mixed with impurities, blocking the flow control valve saving port, causing the operation speed to decline and unstable.

Solution: Clean the flow valve and other components to replace the contaminated oil.

5, there is air in the hydraulic system.

Solution: Find out the reason for the intake of hydraulic system, and adopt the method to sweep the air in the hydraulic system.

6, the internal and external leakage of each component of the system is severe, and the oil flow into the hydraulic cylinder performance chamber is reduced.

Solution: Clear the cause and orientation of internal and external leakage, adopt the replacement of severe wear components and other methods to eliminate internal and external leakage.
