Pulse dust removal valveIt is the core component of the pulse bag filter, which achieves instantaneous release of compressed air through electromagnetic or pneumatic control, forming a pulse airflow to remove dust on the surface of the filter bag and ensure efficient and stable operation of the dust collector.

　　Pulse dust removal valveUsing low-pressure pulse blowing method, the dust cleaning intensity of the filter bag is high, ensuring that the dust on the surface of the filter bag is completely removed. Pulse airflow evenly covers the surface of the filter bag, avoiding local dust accumulation. The regeneration efficiency of the filter bag is high, the equipment resistance is stable, and the dust removal efficiency can reach over 99%.

Common faults and solutions:

1. The valve does not move or opens slowly

Possible reasons: burnt electromagnetic coil, insufficient air source pressure, blockage of impurities inside the valve, and aging of the spring.

Solution: Check the power supply of the coil (replace the burnt coil); Adjust the gas source pressure to the specified range; Disassemble the valve to clean impurities; Replace the aging spring.

2. Valve not tightly closed (leakage)

Possible reasons: worn or deformed sealing gasket, stuck valve stem, scratches on valve seat.

Solution: Replace the sealing gasket; Lubricate the valve stem or replace stuck components; Grind and repair scratches on the valve seat.

3. Poor dust cleaning effect (with more dust residue)

Possible reasons: Insufficient injection time, insufficient air source pressure, and valve blockage leading to insufficient flow.

Solution: Adjust the parameters of the pulse controller; Check if there is any leakage in the gas source pipeline; Clean the debris at the valve port to ensure unobstructed flow.

4. Frequent damage to valves

Possible reasons: The gas source contains oil/water (corrosive components), the working pressure is too high, and the valve and pipeline are not aligned during installation.

Solution: Install a filter (oil and water removal) in front of the gas source; Reduce the pressure to the rated range; Re calibrate the installation position to avoid pipeline stress.
