When customers inquiry about hydraulic press machine and tell us their product size and drawing, best hydraulic press solution will be provided for they. Do you know how to calculate the pressure of hydraulic press machine?
Cylinder ejection pressure (Kg) = cylinder area (square centimeters) × unit area pressure (Kg/square centimeters)

                                                         

After hydraulic oil enters the system, it will encounter resistance from the pipeline along the way and overcome the frictional resistance of relatively moving parts. Due to frictional resistance, the hydraulic oil entering the system is continuously compressed, and the pressure continues to increase. Until the pressure of the hydraulic oil rises to a level that can overcome the above two bridge spring resistances, the gear pump still pumps a certain amount of oil into the system. The fluid is sent into the rodless cavity of the oil cylinder, so the piston moves upwards driven by the hydraulic oil, lifting the heavy object.
During the use of the hydraulic press, if the hydraulic pressure does not increase, the following is an analysis of common problems.
1. During operation, if it is found that the pressure cannot go up or down, it is likely that the reversing valve has failed, causing the system to continue to unload or maintain high pressure.
2. The damping hole of the relief valve is blocked, there are burrs on the main valve core, and there is dirt in the valve core, the valve hole and the gap, etc., which may cause the main valve core to become stuck and in the fully open position, the hydraulic pressure output by the hydraulic pump will The oil returns directly to the tank through the relief valve, that is, the pressure oil line and the return oil line are short-circuited, resulting in a pressure-free system.
3. In a system with a one-way valve, if the direction of the one-way valve is installed in the opposite direction, the pressure may not rise.
4. Leakage inside and outside the system, such as serious leakage between the valve core and the valve body hole, will also cause the system pressure to fail to increase.
