Summary of High-Pressure Boiler Induction Fan Motor Failures
High-pressure boiler induction fans offer excellent performance and provide significant benefits to users and partners.
However, in practical applications, the motor may occasionally exhibit abnormalities. Let’s briefly discuss this issue to help deepen everyone’s understanding. Let’s take a look at the specific details.
This failure manifests as excessive vibration in the high-pressure boiler induction fan motor during operation.
There are three primary causes:
1. If the motor base is not level or improperly installed, it should be readjusted to ensure proper balance.
2. The pulley or fan blades attached to the motor shaft are unbalanced; they should be readjusted;
3. Bearing damage. The second fault involves the motor of the high-pressure boiler induced draft fan failing to operate normally.
This situation primarily includes the following causes:
(1) Power cord blockage; motor burnout; seized or damaged bearings; excessive load; for single-phase motors, a damaged capacitor or poor contact in the centrifugal switch.
The third fault is that the motor overheats during operation of the high-pressure boiler induced draft fan, which may even lead to motor burnout.
Regarding this situation, we believe the main factors to consider are: (1) the high-pressure boiler induced draft fan is overloaded, requiring replacement with a suitable motor;
Second, the power supply voltage is too high or too low, requiring adjustment of the power supply voltage; third, a short circuit or ground fault in the stator winding;
Fourth, poor motor cooling or abnormal airflow; check whether the fan blades are damaged; fifth, excessively high ambient temperature;
Sixth, the capacitor in a single-phase motor is too large. The fourth fault is that the motor housing of the high-pressure boiler induced draft fan is live. There are two main causes for this: first, moisture in the motor; second, aging insulation; third, contact between the wires and the housing; the second factor is a loose or broken ground wire.
