Causes The High Temperature Of The Centrifugal Blower Bearing

When the centrifugal blower is running, the centrifugal blower bearing outer ring allows the temperature should not exceed 95 ° C. If it exceeds this value, the centrifugal blower bearing temperature is too high, also known as the centrifugal blower bearing heat. What is the reason for the high temperature of the motor centrifugal blower bearing? Centrifugal blower bearing heating is one of the most common faults in motors. Lightly, the grease is diluted and leaked, and the centrifugal blower bearing is damaged, causing economic losses to the user. The reason why the temperature of the motor centrifugal blower bearing is high and the treatment method are briefly described below.

1. The centrifugal blower bearing damage, should be replaced.

2. The grease grade is incorrect or too much or too little. General application of No. 3 lithium base grease or No. 3 complex calcium base grease, ZL3 (SY1412-75) or complex calcium base grease. After cleaning the centrifugal blower bearing and cover, add grease to a net volume of about 1/2.

3. Sliding centrifugal blower bearing lubricant is not enough or there are impurities, or the oil ring stuck, should be repaired.

4. The centrifugal blower bearing and the end cover with too loose (outside or too tight). Spray the metal on the journal when it is too loose; rework when it is too tight.

5. The centrifugal blower bearing and the end cover with too loose (outer round) or too tight. End caps when loose; rework when overtight.

6. The centrifugal blower side cover or the centrifugal blower bearing cover is not assembled. Re-flattening.

7. The transmission belt is too tight or too loose, and the coupling is not centered and should be adjusted.
