Filter maintenance methods

Maintenance methods of primary filter and precision filter:

With the progress of Industrial Science and technology, there are more and more kinds of filters with various shapes. Of course, this is the social progress and the industrial demand is also higher and higher. Although the shapes are various, the overall classification is also coarse filter and precision filter. Here are the maintenance methods for you.

Primary filter:

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

2. When the filter works for a period of time, some impurities are precipitated in the filter core. At this time, the pressure drop increases, and the flow rate decreases. 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 element shall not be deformed or damaged, otherwise, the filter installed again, the purity of the medium after filtering cannot meet the design requirements, and the compressor, pump, instrument and other equipment will be damaged;

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

Precision filter:

1. The core part of the precision filter is the filter element, which is composed of special materials and is suitable for damage and needs special protection;

2. When the precision filter works for a period of time, a certain amount of impurities are trapped in the filter element. At this time, the pressure drop increases and the flow rate decreases. It is necessary to remove the impurities in the filter in time and clean the filter element at the same time;

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

3.Some precision filter elements cannot be repeatedly used, such as bag filter element and polypropylene.
