What are the methods for adjusting hydraulic cylinder pressure?

Adjust the pressure of the hydraulic cylinder can be realized through the following methods:

      1, adjust the relief valve: relief valve is a commonly used pressure regulating element in the hydraulic system. By adjusting the opening of the relief valve or adjusting the pressure setting, you can control the pressure level in the hydraulic system. When the pressure reaches the set value, the relief valve will automatically open, so that the excess liquid back to the tank, thus limiting the system pressure.

      2, adjusting the regulator: regulator is a hydraulic system can be adjusted in the working pressure of the components. By adjusting the opening or pressure setting of the regulator, you can control the pressure level in the hydraulic system. Regulator is usually installed in the main control valve inlet or return line, used to limit the inflow or return pressure.

      3, regulating control valves: control valves in the hydraulic system can be used to regulate the pressure of the hydraulic cylinder. By adjusting the opening or setting of the control valve, you can change the speed of the device's liquid supply or discharge, thus indirectly regulating the pressure of the device.

      4, adjust the output pressure of the pump: the pump in the hydraulic system is to provide liquid flow and generate pressure of the key components. By adjusting the output pressure of the pump, you can directly affect the pressure level of the device. Adjust the pump displacement, pump speed or use a governor and other ways to change the output pressure of the pump.

      When making pressure adjustments, the following points need to be noted:

      1, to avoid hydraulic system failure: when adjusting the pressure, care should be taken not to be greater than the rated working pressure range of the hydraulic system, in order to avoid system failure or accidents.

      2, monitoring and testing during the commissioning process: when adjusting the pressure, you can monitor and test the pressure in real time with the help of pressure gauges, pressure sensors and other equipment to ensure the accuracy of the pressure adjustment.

      3, before and after the adjustment of the system performance test: after adjusting the hydraulic cylinder pressure, the system performance test should be carried out to verify that the effect of adjustment meets the requirements.
