The filter is a device that removes impurities, which can protect the normal operation of the equipment, and is also an indispensable device on the pipeline of the conveying medium. The removal rate of suspended solids in water can reach more than 95%, and it has a certain filtration effect on macromolecular organic matter, bacteria, viruses, colloids, iron and other impurities.

● Coarse filter filter

1. The core part of the filter is the filter core, which is composed of the filter frame and the stainless steel wire mesh, which is a suitable part and needs special protection;

2. When the filter works for a period of time, certain impurities are precipitated in the filter core, then the pressure drop increases, the flow rate will decrease, and the impurities in the filter core need to be removed in time;

3. When cleaning impurities, special attention should be paid to the stainless steel wire mesh on the filter element can not be deformed or damaged, otherwise, the purity of the filtered medium after filtration cannot meet the design requirements, and the compressor, pump, instrument and other equipment will be damaged;

4. If the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately.
