Common Faults and Elimination Methods of High Pressure Fan

(A) the fan does not rotate

1, no power supply - power supply

2, the motor does not work - check the motor wiring or replace the motor

3, the fan head damage - repair fan or replacement

4, the fan has a foreign body stuck - remove foreign body

(B) the noise increases

1, bearing dry lubrication - plus bearing grease

2, bearing damage - replace the bearing

3, impeller wear - replace the impeller or pump head

4, fasteners loose or off - tighten the fasteners

5, foreign body in the fan - to clear the foreign body or replace the pump head

1, bearing damage - replace the bearing

2, impeller imbalance - clear the impeller in the foreign body or static balance

3, spindle deformation - replace the spindle or pump head

4, the working state into the turbulent area - to adjust the working state, to avoid the turbulent area

5, into the air inlet into the filter plug - cleaning filter

(D) the temperature rise

1, the inlet temperature is too high - to reduce the inlet temperature

2, bearing dry lubrication - plus bearing grease

3, fan efficiency reduction - remove leaf dust or replace the pump head

4, working state change - adjust the working state

5, the ambient temperature increases - increase the environment ventilation cooling

(5) the pressure is reduced

1, pump head speed reduction - low supply voltage or motor failure

2, pipe network resistance increase - reduce pipe network resistance

3, working state change - adjust the working state

4, the motor steering reverse - the motor rewiring

(6) traffic reduction

1, import and export gas filter plug - cleaning filter

2, pump head speed reduction - low power supply voltage or motor failure

3, pipe network resistance increase - reduce pipe network resistance

4, increase the working state - adjust the working state

5, the motor steering reverse - the motor rewiring
