Oil purifier filter maintenance and maintenance knowledge

Coarse filter:

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

2. After the filter has been working for a period of time, a certain amount of impurities will be 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 core. It cannot be deformed or damaged. Otherwise, the purity of the medium after the filter is installed will not 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.

T-type filter is a device for removing solid impurities in the process of pipeline transportation of liquid. When the liquid flows through the filter, the impurities in it are filtered out, which can protect the normal operation of the pump, compressor, instrument and other equipment. It is very convenient to use and maintain. T-type filters are suitable for the following media:

① Weakly corrosive materials in chemical, petroleum production and urban heating, such as water, ammonia, oil products, hydrocarbons, etc.;

② Corrosive materials in chemical production, such as soda ash, sulfuric acid, nitric acid, acetic acid, etc.;

③ Low-temperature materials in refrigeration and air separation production, such as liquid methane, liquid nitrogen, liquid oxygen and various refrigerants; ④ Materials with hygienic requirements in light food and pharmaceutical production, such as beverages, medical supplies, etc.

The filter has a high degree of automation, high product technology content, reliable operation, long life, low maintenance cost, comprehensive long-term benefits, and almost no loss in power consumption, water consumption, labor, maintenance and other costs compared to hydraulically actuated filters.

Precision filter

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

2. After the precision filter has been working for some time, the filter element will intercept 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 at the same time;

3. When removing impurities, pay special attention to the precision filter element. It must not be deformed or damaged. Otherwise, the purity of the medium after filtration of the installed filter element will not meet the design requirements;

4. Some precision filter elements cannot be reused many times, such as bag filter elements, polypropylene filter elements, etc.;

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