What should I do if the working speed of the hydraulic press drops?


1. The output oil flow of the hydraulic pump is small and the pressure is low.

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

2. The oil temperature increases, the oil viscosity decreases, the leakage increases, and the energy flow decreases.

Solution: Control the oil temperature.




3. The hydraulic system planning of the hydraulic press is unreasonable. When the load changes, the flow into the hydraulic actuator also changes accordingly, resulting in a decrease in the speed of the actuator.

Solution: Reasonably plan the hydraulic system so that the system flow does not change with the pressure change.

4. Impurities are mixed in the oil, blocking the saving port of the flow control valve, causing the operation speed to drop and become unstable.

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




5. There is air in the hydraulic system.

Solution: find out the reason for the intake of the hydraulic system, and take measures to remove the air in the hydraulic system.

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

Solution: clarify the cause and location of internal and external leakage, and take measures such as replacing severely worn components to eliminate internal and external leakage.
