13. Troubleshooting Perform troubleshooting of the collector in accordance with the following: Troubleshooting Chart TROUBLE POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Visible dust from outlet
1 – Cartridge is improperly installed. 2 – Cartridges too loose. 3 – Damaged cartridges. 4 – Damaged gaskets. 5 – Leakage at tube sheet level. 1 – Inadequate cleaning air supply. 2 – Improper solenoid valve operation.
1 – Check cartridge installation; repair as necessary. 2 – Re-install filters. 3 – Replace damaged cartridge. 4 – Replace gasket or cartridge. 5 – Check tube sheet joints repair as necessary. 1 – Check air supply. 2 – Check solenoid valves; steady rush of air indicates open valve; no air pulse indicates a plugged valve; possibly due to electrical failure; repair as necessary. 3 – Replace pulse controller. 4 – Check collector for excessive moisture or high relative humidity; either will seriously affect collector operation; correct moisture level in air stream. 5 – Check fan rotation, fan speed, damper position, outlet cfm; correct as necessary to obtain specified air flow. 6 – Replace with cartridges of proper media for type of air. 7 – Check air temperature; correct reason for overheat condition. 8 – Ground collector and its components. 1 – Check fan rotation; correct if wrong. Switching two of the 3-phase connections will reverse the direction of rotation of the motor. 1 – Check reason for high temperature; correct if possible. 2 – Check composition of air; consult with factory on compatibility of cartridge material with air stream. 3 – Eliminate moisture from air; replace cartridge. 4 – Check cartridge for damage from over clamping. 5. Check for impingement.
Cartridge filtering action rapidly impaired.
3 – Defective pulse controller. 4 – Excessive moisture entering collector and blinding cartridges.
5 – Incorrect air flow (too high or too low). 6–Incorrect cartridge filters media for air composition. 7 – Air temperature higher than specification. 8 – Static electricity build-up in collector.
Air flow through system below design rating
1 – Incorrect fan rotation
Filter cartridges deteriorate rapidly.
1 – High collector temperature.
2 – Chemical composition of air stream incompatible with cartridge material. 3 – Moisture in air stream. 4 – Incorrect cartridge installation. 5 – Abrasion by impingement of high velocity particles.
