Key words: Roots blower

We use Roots blower In the project, we often encounter the situation of being locked up and unable to move. In practice, we can sum up the following points for your reference:

 

Foreign body stuck

 
There are large particles into the fan cavity, blocking the gap of each part, forming the fan can not roll. This requirement is to sort out the foreign matters inside the chamber and to check the clearance between the impellers. In addition, check the cause of foreign matter falling in to prevent the failure from happening again.
 

2、 Damage and rupture of impeller

 
The impeller is damaged and the fan is stuck. We know this problem very well. The impeller and impeller bite each other, resulting in the impeller unable to rotate. This kind of fault can be roughly checked at the inlet of the fan. If the inlet cannot be seen, the fan can be disassembled for detailed inspection.
 

3、 Damage of bearing gear

 
   Roots blower There are four bearings on it. If the bearings are damaged, the clearance between the impeller and the impeller will change, and the impeller will rub, causing the fan to be unable to rotate. This is the indirect reason for the change of impeller clearance, It is also a common reason for the impeller not to rotate. Serious waiting is gear damage and broken teeth. In this process, the noise will change. You can pay attention to the rotating noise of the fan at ordinary times.
 

4、 Rusty and stuck

 
We often encounter the problem that roots does not lock when using it for a long time Roots blower The internal clearance requirements are very strict, and the clearance is very small, Roots blower If it is idle for a long time, it will rust inside and outside, so that the gap will be rusted. The solution to this problem is to first use a proper amount of diesel oil into the casing and soak it for a period of time. If it is not loose, remove the fan for cleaning.

5、 Motor failure

 
Idle for a long time Roots blower If there is no rotation, the motor and fan can be disconnected, and the motor and fan can be rotated separately. If there is a motor fault, it will naturally lead to the situation that the motor can not be turned because the fan and the motor are linked together, which is the reason to disconnect the connection between them and open them separately. The troubleshooting method is used.
 

6、 Casing deformation

 
It is very rare that the case of the three leaf roots blower does not work due to the casing deformation. There are a few cases that the casings produced by some manufacturers are not up to standard. For Roots blowers with the same model and low price, the casing may be thin. If the casing is too thin, the case may be deformed, The deformation of the casing will naturally cause the impeller to be stuck, and there is a certain standard clearance between the casing and the impeller.
 
The above is the summary of the immovable lock. I hope it can help you in the future practice. If you have any problems, please contact our manufacturer.
