How to deal with motor failure of three blade roots blower?

How to deal with motor fault of three blade roots blower? When we use Roots blower, we often encounter motor failure. Xinqianshun will give you a comprehensive analysis. I hope the following can help you!

1. Foreign matter stuck

There are large particles entering the fan cavity, blocking the gaps of all parts, causing the three leaf roots fan unable to rotate. This kind of fault requires cleaning the foreign matters in the cavity and checking the clearance between impellers. In addition, check the cause of foreign matter falling in to prevent the fault from happening again

2. Impeller damaged

The impeller is damaged. The fan is stuck and can't rotate. This kind of fault is easy to understand. The impeller and the impeller occlude each other, causing the impeller to not rotate. This kind of fault requires disassembly and inspection of the casing.

3. The gear is damaged

The meshing area of normal gears is about 2/3, and if it is larger than this, the meshing force between gears is too large, which causes the gears to fail to rotate, thus causing the fan to fail to rotate.

4. Bearing damage

There are 4 bearings on Roots blower. If the bearing is damaged, the clearance between the impeller and the impeller, the casing, and the wallboard will change. The friction of the impeller will cause the fan to fail to rotate. This is the indirect reason for the change of the impeller clearance and the common reason for the impeller to fail to rotate.

5. Rust jamming

Roots blower has been idle for a long time, and rust will appear inside and outside, and the impeller is embroidered with the wallboard or casing; Or the rust falls off in a large area, which may lead to seizure between impellers. In this case, the rust shall be cleaned by means of kerosene immersion, gasoline washing, etc., and the clearance shall be adjusted.

6. Parts deformation

It is rare that the deformation of parts causes the three leaf roots blower not to rotate. A few manufacturers blindly reduce costs and cause the strength of parts not to meet the standard. The roots blower with the same model and low price is likely to have thin casting thickness, thin journal, etc. If the strength of parts does not meet the standard, parts may be deformed, The clearance between parts is damaged, causing the fan to be stuck and unable to rotate. In addition, long-term placement of products will also cause deformation of parts.

7. Motor damage

If there is a motor fault of the three leaf roots blower that has been idle for a long time, it will naturally become immovable, and the motor fault is easy to judge. If the motor cannot rotate, the fan will naturally not rotate. If it is a motor fault, the motor of the fan should be checked, and then the fault should be eliminated.
