How To Deal with Membrane Filter Press Leakage

Membrane filter press is a common equipment for industrial solid-liquid separation. Once leakage occurs, it will not only affect work efficiency, but also cause material waste and environmental pollution. Therefore, it is very important to find out the cause of leakage in time and deal with it effectively.

Filter cloth problem is one of the common causes of leakage. Wrinkled, damaged or unevenly installed filter cloth will cause poor sealing between filter plates. When handling, the equipment must be stopped first and the filter cloth must be carefully checked. If the filter cloth is damaged, it should be replaced in time; if there are wrinkles, it needs to be re-installed flat to ensure that the filter cloth evenly covers the surface of the filter plate and fits tightly.

Filter plate failure can also easily cause leakage. Wear and deformation of the filter plate edge, scratches or impurities on the sealing surface will destroy the sealing performance. For slightly worn filter plates, sandpaper can be used to polish and repair; if the wear is serious, a new filter plate needs to be replaced. At the same time, the filter plate sealing surface must be cleaned before and after each use to remove impurities and ensure that the sealing surface is clean and smooth.

Abnormal pressure system may also cause leakage. If the filtration pressure is insufficient, the filter plate cannot fit tightly; if the pressure is too high, the filter plate and filter cloth may be damaged. According to the material characteristics and equipment parameters, the pressure value should be adjusted reasonably, and the pressure sensor and hydraulic system should be checked regularly to ensure stable and accurate pressure. In addition, loose pipe connections and aging of sealing rings can also cause leakage. It is necessary to check each pipe interface one by one, tighten the loose parts, and replace the aging sealing rings.

The treatment of leakage in the membrane filter press requires a comprehensive investigation and corresponding measures should be taken for different reasons. In daily use, good equipment maintenance and regular inspection of the condition of each component can effectively prevent leakage problems and ensure the stable operation of the membrane filter press.
