The filter has a wide range of applications. For example: it can be used as a pretreatment device for drinking water treatment, food industry water, production water treatment equipment in the electronics industry, etc. When the water treatment filter is used normally for a long time, it must be maintained regularly. . The following briefly introduces the daily maintenance methods of coarse filter filters.

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

　　2. After the water treatment filter has been working for a period of time, certain impurities are deposited in the filter core. At this time, the pressure drop will increase and the flow rate will decrease. The impurities in the filter core need to be removed in time;

3. When cleaning impurities, pay special attention to the stainless steel wire mesh on the filter element not to be deformed or damaged. Otherwise, if the filter is installed, the purity of the medium after filtration does not meet the design requirements, and the compressor, pump, instrument and other equipment will suffer To destruction;

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