(a) fan does not rotate

1, not turn on the power-processing power

2, motor doesn't work-check motor wiring or replacement motor

3, fan head damage repair fan or replacement.-

4, fan of foreign card dead-removal

(2) the noise increased

1, bearing and bearing grease lubrication, dry

2, bearing damage--change bearing

3, impeller, replace or pump impeller wear head

4, strong a loose or fall off-tight fasteners

5, fan-there were foreign body removal or replacement pump head

(3) increase vibration

1, bearing damage--change bearing

2, the impeller don't balance-remove the impeller foreign or school static and dynamic balance

3, main shaft deformation, spindle or replacement pump head

4, condition into turbulent earthquake zone-working status, avoid turbulent adjustment to the quake zone

5, in and out carbon monoxide into mesh jam-clean screen pack

(4) temperatures

1, inlet temperature is too high-lower inlet temperature

2, bearing and bearing grease lubrication, dry

3, fan-clear way to low efficiency, dust or replacement pump head

4, condition change-adjust working state

5, environmental temperature increases-increasing environmental ventilation cooling

(5) pressure decrease

1, pump head speed reduce power supply voltage, low fault or motor

2, and the pipeline resistance increases-lower resistance of pipelines

3, condition change-adjust working state

4, motor to reverse-motor to wiring

(6) flow decrease

1, import and export gas filter jam-clean screen pack

2, pump head speed reduce power supply voltage, low fault or motor

3, and the pipeline resistance increases-lower resistance of pipelines

4, working status-adjust working state. Increase

5, motor to reverse-motor to wiring
