Filter bags are core consumables of industrial filtration systems. Regular maintenance and standardized replacement are the keys to ensure stable operation of production lines and extend equipment service life. Due to lack of standardized maintenance, most factories suffer from reduced filtration efficiency and increased equipment load, which affects overall production efficiency.
Key Points of Daily Maintenance
- Regular Inspection: Check the surface of filter bags daily to observe damage, aging, scaling and blockage;
- Cleaning & Maintenance: Reusable filter bags are recommended to be cleaned by low-pressure blowing or regular water flushing to remove surface impurities and prevent pore blockage;
- Working Condition Control: Strictly control the temperature and acid-base concentration of filtration medium to avoid exceeding the tolerance range of filter bag materials.
Replacement Judgment Standard
- Continuous increase of filtration resistance and obvious decrease of flow rate indicate severe blockage of filter bags;
- Cracking, wear and leakage of bag body that cannot meet the sealed filtration requirements;
- If medium impurities exceed the standard and finished product purity is unqualified, batch replacement shall be carried out immediately.
Timely replacement of aging and failed filter bags can effectively protect filtration equipment, reduce shutdown maintenance time, and help enterprises achieve high-efficiency and low-cost filtration operations.
