What are the reasons and countermeasures for the low closing pressure of the filter plate?

During 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 are major problems in the installation of the filter plate limit detection device. The position error causes the filter plate displacement control system to lift up and control the hydraulic pump to stop working prematurely: if the filter plate closing pressure is set too small, it will also cause the filter plate closing pressure to be small.
Treatment method: Regularly inspect each operating component of the filter press. Once the hydraulic oil level is found to be too low, refill the hydraulic station tank with hydraulic oil in a timely manner 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. Once leakage is found at the joint or the cylinder seal ring is worn, the O-ring or sealing ring should be replaced. If the oil pipeline leaks, repair the oil pipeline in time to fully protect the hydraulic pipeline. integrity,
The filter plate in-position detection device is installed forward. If the oil pump stops working in advance, the position of the filter plate in-position device needs to be readjusted to ensure that the closing pressure meets the requirements. The setting value of the closing completion pressure parameter of the filter press hydraulic cylinder is small, and the hydraulic oil pump enters the stop state in advance. In this case, the closing completion pressure parameter must be reset to ensure that it meets the closing completion pressure standard requirements.
