①, coarse filter filter

1, the core part of the filter is the filter core, the filter core is composed of the filter frame and stainless steel wire mesh, stainless steel wire mesh is suitable for loss, need special protection;

2, when the filter works for a period of time, the filter core precipitates a certain amount of impurities, then the pressure drop increases, the flow rate will decrease, need to remove the impurities in the filter core in time;

3, when cleaning impurities, pay special attention to the stainless steel wire mesh on the filter element can not be deformed or damaged, otherwise, the filter is installed, the purity of the filtered medium can not meet the design requirements, and the compressor, pump, instrument and other equipment will be destroyed;

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

②, precision filter

1, the core of the precision filter is the filter element, the filter element is composed of special materials, is suitable for loss, need special protection;

2, when the precision filter works for a period of time, the filter element contains a certain amount of impurities, then the pressure drop increases, the flow rate will decrease, it is necessary to remove the impurities in the filter in time, while cleaning the filter element;

3, when removing impurities, pay special attention to the precision filter element, shall not be deformed or damaged, otherwise, the filter element installed again, the purity of the filtered medium can not meet the design requirements;

4, some precision filter, can not be used repeatedly, such as bag filter, polypropylene filter, etc.;

5. If the filter element is deformed or damaged, it needs to be replaced immediately.
