Hydraulic press machine is a kind of hydraulic equipment widely used in industrial production, mainly used for metal products such as stretching, molding, press fitting, calibration, bending and other processes, but also applicable to non-metallic materials, powder metallurgy products of the press. In the process of use, sometimes back to the situation of pressure reduction, so what are the reasons for the pressure reduction of the hydraulic press machine?
1. Insufficient hydraulic oil: The low oil level of the tank will cause the hydraulic pump to suck empty and cannot supply oil normally, thus causing insufficient pressure.
2. Hydraulic oil thinning: in the high temperature environment, the viscosity of the hydraulic oil is reduced, which will easily lead to insufficient pressure.
3. Hydraulic pump wear or leakage: after long-term use, the hydraulic pump internal parts wear, resulting in increased leakage, output flow and pressure drop.
4. Hydraulic pump installation or connection error: such as the hydraulic pump inlet and outlet reversed, will lead to the hydraulic pump can not work properly.
5. Failure of the relief valve: the relief valve spool and seat sealing, fatigue fracture of the regulator spring or damping hole blockage, will lead to system pressure can not be established or maintained.
6. Solenoid valve failure: solenoid valve used for too long, spool wear or leakage, will lead to system pressure drop.
7. Hydraulic cylinder leakage: hydraulic cylinder piston seal wear or aging, will lead to the hydraulic cylinder between the two chambers of oil string, thus reducing system pressure.
8. Oil pipe leakage: hydraulic system in the oil pipe, joints and other parts of the leakage, will lead to hydraulic oil can not effectively transfer pressure.
9. Hydraulic system contamination: hydraulic oil mixed with impurities, dirt or air, will lead to hydraulic pumps and valves clogged or worn, affecting the pressure transfer.
10. High oil temperature: high oil temperature will lead to a reduction in the viscosity of the hydraulic oil, which in turn affects the system pressure.
12.Pressure maintaining check valve leakage: If the system is installed in the pressure maintaining check valve, its leakage will also lead to pressure drop.
In short, in order to the normal operation of the hydraulic press machine and extend its service life, regular maintenance of the hydraulic press machine is needed.
