How to debug the Four Column hydraulic Press hydraulic station?

1. Zero adjustment, including the zero adjustment of the Four Column hydraulic Press servo valve and the zero adjustment of the servo amplifier. In order to adjust the zero position of the system, a bias voltage is sometimes added;
2. Static test of the hydraulic press system, determine the static relationship between the controlled parameters and the command signal, and adjust the reasonable amplification factor. Generally, the larger the amplification factor, the smaller the static error and the higher the control accuracy, but it can easily cause system instability;
3. Dynamic testing of the Four Column hydraulic Press system uses dynamic testing instruments. It is usually necessary to measure the system stability, frequency response and error to determine whether it can meet the design requirements. The system dynamic and static test records can be used to evaluate the system operating status in the future. according to.
4. After the hydraulic station is put into operation, the relevant values, oil temperature, oil pressure and oil pollution degree, as well as the operation stability, zero deviation of the actuator, and the tracking of signals by the actuator should be regularly checked and recorded.
