Effective maintenance and troubleshooting are crucial for ensuring optimal performance of dust suppression fog cannons. Here are common issues encountered with these systems and practical solutions to address them.

1.Simultaneous Water and Gas Spray Issue:

     Issue: Water and gas spray simultaneously.

     Possible Causes: Unsoldered welds on the infusion tube inside the dust suppression fog cannon barrel, or corrosion of the infusion tube due to chemical liquids.

2.No Mist or Dripping Water:

     Issue: No mist or dripping water.

     Possible Causes: Blocked filter in the fog cannon casing, or oblique hole blockage in the nozzle.

     Solution: Remove and clear the blockage as necessary.

3.Air Cylinder Inoperable:

     Issue: Air cylinder unable to intake air.

     Possible Causes: Shrunken and hardened cup in the fog cannon, or wear and breakage of the fog cannon machine.

     Other Cause: Loose screw at the bottom of the cup.

     Solution: Expand shrunken leather cup by soaking in engine or animal oil, or replace with a new one. Tighten loose screws after installation.

4.Scattered Mist Instead of Conical Spray:

     Issue: Sprayed mist is scattered, not conical.

     Possible Cause: Incorrect nozzle shape or nozzle blockage.

     Solution: Unscrew nozzle cap to adjust, and clean dirt from the nozzle hole to improve atomization.

5.Water Leakage from Plug Rod and Gland:

      Issue: Water leakage from plug rod and gland.

      Possible Causes: Unsoldered cylinder wall or bottom, or steel ball stuck by dirt in valve housing.

      Solution: Perform welding repairs or remove dirt accordingly.

6.Air Cylinder Gland or Water Filling Cap Leakage:

      Issue: Leakage from air cylinder gland or water filling cap.

      Possible Cause: Insufficient tightness.

      Solution: Check and replace damaged or uneven rubber gasket. Ensure flange connection with gas cylinder is intact. Repair desoldering if necessary.

7.Switch Water Leakage:

      Issue: Water leakage from the fog cannon switch.

      Possible Causes: Damaged switch or aging asbestos rope under switch cap.

      Solution: Replace with new switch or asbestos rope as needed. Tighten fog cannon appropriately.

By understanding these common issues and their solutions, operators can enhance the reliability and efficiency of dust suppression fog cannons. Regular maintenance and timely troubleshooting not only extend the lifespan of the equipment but also ensure continuous operation in various industrial applications.
