System principle of bag filter
Inside the filter, the filter bag is supported by a metal inner mesh. The liquid flows from the inlet and flows out through the filter bag. Impurities are intercepted in the filter bag. The filter bag can be replaced or cleaned and used again.
Daily use
The filtration system at work should always check the pressure difference between the inlet and outlet. When the pressure difference reaches 0.05-0.1Mpa, the filter bag should be replaced in time to avoid the pressure difference over the ambassador filter bag rupture and the support net damage.
Monitoring filter quality
When the liquid input pressure is stable, the filtration quality is closely related to the pressure difference in the filter bag. If the pressure difference is too large, the filtration pore size of the filter bag is blocked and the filtration rate is reduced. Therefore, we suggest that when the bag filter starts to work, the pressure difference should be checked regularly, and the time for replacing the filter bag is determined by the pressure difference shown by the front and rear pressure gauges. Generally, the filter bag can withstand 0.5-1 Kg/cm2 (0.05). -0.1Mpa or so, when the pressure difference reaches this range, the filter bag should be replaced in time to avoid the filter bag cracking, affecting the filtering effect.
If the pressure drop suddenly drops, stop the filtration immediately and check for leaks.
How to clean bag filter
If the bag filter continues to filter the same liquid, it does not need to be cleaned. However, if other types of liquids are filtered, they must be cleaned before being used.
