We know that the Filter Press is composed of a filter press frame, filter plate, hydraulic system, filter cloth and other transmission systems. Especially for the Plate and frame filter press, its operation is relatively simple and intuitive compared with other filter press equipment. For the filter press, whether it is a plate and frame filter press or a belt filter press, it may sometimes encounter some similar faults in the hydraulic system during operation. We know that the hydraulic system is a key functional component in a filter press. Without the hydraulic system, the filter press cannot filter the material. Let's take a look at the troubleshooting and reference of the hydraulic system of the plate and frame filter press.

We know that the hydraulic pressure of the plate and frame filter press is mainly a component that provides pressure for the operation of the entire machine. When the oil chamber A is filled with more oil, the piston moves to the left, pressing the filter plate to make it closed. When the oil chamber B is filled with more oil, the piston moves to the right, and the filter plate is loosened. Due to the precision manufacturing, the hydraulic system has fewer faults, and you only need to pay attention to daily maintenance. However, due to wear, oil leakage will occur every year or so, and then the O-ring must be repaired and replaced.

There are many types of hydraulic failures that we see in daily life, such as problems related to hydraulic cylinder propulsion and pressure maintenance. According to the analysis of relevant industry insiders, the general causes of the failure to maintain pressure are oil leakage, wear of the sealing ring, and abnormal operation of the solenoid valve. The reference method for handling in the general industry is to remove the valve to be inspected and ｒｅｐｌａｃｅ the sealing O-ring, then clean the solenoid valve or ｒｅｐｌａｃｅ it, and then conduct a reasonable inspection of other components. During the operation of the plate and frame filter press, the plate and frame are continuously compressed. During the compression process, the plate itself and the filter cloth are also prone to damage or blockage. This situation requires us to pay more attention and understand and observe during maintenance.
