The closing pressure of the filter plate of the plate and frame filter press is small
March 14, 2024
In the actual operation of the plate and frame
Filter Press, if the liquid level in the hydraulic station tank is low, it may be caused by leakage points in the hydraulic pipeline, which will cause pressure loss in the hydraulic station; there is a problem when the filter plate limit detection device is installed A large position error will cause the filter plate displacement control system to float up and control the hydraulic pump to stop working in advance; if the closing pressure of the filter plate is set too small, it will also cause pressure loss in the hydraulic station, causing the pressure of the filter plate to be too low.
Approach:
Regularly check the operating components of the filter press. Once the hydraulic oil level is found to be too low, fill the hydraulic station tank with oil in time to ensure that it meets the requirements for normal operation; at the same time, check the sealing of the hydraulic pipeline joints and the integrity of the hydraulic pipeline. . If there is leakage at the cylinder joint or the sealing ring is worn, if there is leakage in the oil line, the O-ring or sealing ring should be replaced, and the oil line should be repaired in time to ensure the integrity of the hydraulic pipeline. The filter plate detection device is installed in front of the oil pump to ensure the oil pump is in advance. stop working. It is necessary to readjust the position of the filter plate seating device to ensure that the closing pressure meets the requirements. The pressure parameter setting value after the filter press hydraulic cylinder is closed is small, and the hydraulic oil pump enters the stop state in advance. In this case, the pressure parameters need to be reset to ensure that they meet the requirements of the pressure standards.
