How to check if the bag filter is leaking or broken?

Bag filter is a commonly used dust filtration equipment in industrial production. It filters dust through bags, effectively reducing the impact of dust on the environment and health. However, during use, due to various reasons, the bag filter may experience bag leakage or breakage, which affects its normal working effect. This article will introduce some commonly used methods to help you check whether the bag filter is leaking or broken, to ensure its normal operation.

  1. Observe the appearance
    Firstly, you can carefully observe the appearance of the bag filter. Check if the cloth bag is deformed, wrinkled, or worn. If obvious damage or wear is found, it is likely that the bag is leaking or broken. At this time, the cloth bag should be replaced in a timely manner to ensure the normal operation of the dust collector.
  2. Check the interface and sealing condition
    Secondly, you can check if the interface between the bag and the dust collector is tight and there is no looseness or detachment. At the same time, it is necessary to check whether the sealing components are intact and undamaged to ensure that there is no air leakage during use. If loose interfaces or damaged seals are found, they should be repaired or replaced in a timely manner to avoid bag leakage or damage.
  3. Test pressure difference
    Pressure difference is one of the important indicators for detecting the working status of bag filter. You can determine whether the bag is leaking or broken by testing the pressure difference. Firstly, record the pressure difference value during normal operation. Then, close the dust collector and check if there is a significant change in the pressure difference value. If the pressure difference significantly increases, it is likely that the bag is leaking or broken. At this point, it is necessary to replace or repair the cloth bag.
  4. Check air tightness
    The airtightness of a bag filter is crucial for its normal operation. You can check if the airtightness is normal by using the following methods. Firstly, close the dust collector and seal the inlet and outlet pipelines. Then, apply a certain pressure to the dust collector with an air pump and observe if there is any obvious air leakage. If gas is found leaking from the cloth bag or interface, it is likely that the bag is leaking or broken. At this point, it is necessary to repair or replace the cloth bag in a timely manner.
  5. Regular cleaning and maintenance
    In addition to regular inspections, regular cleaning and maintenance of the bag filter are also very important. Regular cleaning can effectively reduce the blockage and wear of the cloth bag, extend its service life, and ensure its normal dust removal effect. At the same time, regular replacement of cloth bags should be carried out to ensure the stability of their filtration and usage effects.
