1. Due to poor dust removal by the dust collector, the collected dust hardens on the filter bag; Needle felt filter bag
2. Caused by corrosion caused by the condensation of water or acidic gases;
3. Burn off due to high temperature;
4. Improper installation tension may cause the filter bag to become loose or tight;
5. Due to improper adjustment of the tension spring;
6. Collision with adjacent filter bags, frictional contact;
7. Damaged by human or tool contact during installation, repair, or inspection;
8. Unreasonable selection of wind speed or excessive filtration load;
9. The unreasonable design of ash removal parameters leads to high system resistance and is also one of the reasons for the damage of stripped fibers.
