①, coarse filter

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

2. After the filter has been working for a period of time, certain impurities have settled in the filter core. At this time, the pressure drop increases and the flow rate will decrease. It is necessary to remove the impurities in the filter core in time;

3. When cleaning impurities, pay special attention to that the stainless steel wire mesh on the filter core cannot be deformed or damaged. Otherwise, if the filter is installed again, the purity of the filtered medium does not meet the design requirements, and compressors, pumps, instruments and other equipment will be affected. To destruction

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

②, precision filter

1. The core part of the precision filter is the filter element. The filter element is made of special materials, which is a wearable part and needs special protection;

2. When the precision filter works for a period of time, the filter element will hold a certain amount of impurities. At this time, the pressure drop will increase and the flow rate will decrease. It is necessary to remove the impurities in the filter in time and clean the filter element;

3. When removing impurities, pay special attention to the precision filter element, which must not be deformed or damaged, otherwise, the filter element will be installed again, and the purity of the filtered medium will not meet the design requirements;

4. Certain precision filter elements cannot be used repeatedly, such as bag filter elements, polypropylene filter elements, etc.;

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

③, Pay attention to anti-rust, paint or butter on the flange and heat preservation
