Roots FansWhat are the common failures in the process of use? Roots fan small editor to take you to understand.
I. Problem of insufficient airflow
1. Large rotor gap Treatment method Adjust the gap with a tool.
　2. Seal leakage Treatment Replace the sealing device.
　3. Filter mesh clogging Treatment is to replace or clean the filter.
Second, the motor overload problem
1. The lubricant does not work, here it is recommended to switch to high-quality lubricants.
2. The oil ring does not rotate or rotates too slowly, here it is recommended to repair or replace.
3. The fan shaft motor is poorly centered, and re-centering is recommended here.
Third, the seal wear problem processing
1. Seal ring and shaft sleeve coaxiality error, the solution to replace the worn parts.
2. The shaft is bent or debris enters the sealing ring, the solution is to remove the debris and carry out shaft calibration.
3. Rotor vibration is too large or bearing clearance is too large, the solution is to replace the bearing to clear the deformation effect.
