② High fan temperature
③ Motor burning
④ Reversing fan
⑤ Impeller damaged
　　
In the process of sewage treatment, the aeration disk is easy to be blocked. If a large number of aeration disks are blocked in the process of use, it will lead to insufficient aeration or no aeration.
 
3. Three blade roots blower fault
If Roots blower is used for a long time, all parts will be aged and corroded, and various small problems will occur, such as reduced aeration or no aeration.
 
4. Three blade roots blower pipe
① In the use of three blade roots blower sewage tank aeration, if the pipeline is blocked or damaged, the aeration amount will be affected;
② If the pipeline is too long or there are too many bends, the aeration rate will also be affected.
The above is the reason for insufficient aeration of the three blade roots blower. The roots blower manufacturer explained that the problem is, and I hope it can help you! If you have any problems with the three blade roots blower, please contact the Xinqianshun Roots blower manufacturer, and the technician will give you an answer!
