Roots blower Ah, what if it gets stuck? Don't panic. This is the solution

Roots blower is widely used in the industry, and some failures often occur due to improper operation. Please do not panic when the Roots blower is stuck. Let's find the reason first.

Here we list several possibilities of Roots blower stuck, please read carefully:

① Gear damage

The normal gear blocking area is about 2/3 and larger than the meshing area. The meshing force between gears is too large, making the gears unable to rotate, and then the impeller will not move.

② The rusty ones are stuck

Roots blower It has been idle for a long time, and the inside and outside will rust. The rust falls off in a large area, and the impeller may be stuck. In this case, it is necessary to clean the rust with kerosene immersion, gasoline washing, etc., and adjust the clearance.

③ Foreign matter is stuck

Large particles enter the fan, blocking the gap between components, causing the fan not to rotate. This requires cleaning the foreign matter in the cavity and checking the clearance between the impellers. At the same time, check the cause of foreign matter falling in order to avoid failure again.

④ Bearing damage

Roots blower has 4 bearings. If the bearing is damaged, the clearance between the impeller and the impeller, the shell and the wallboard will change, and the impeller will rub, causing the fan not to rotate. This is an indirect cause of the change in impeller clearance. This is also a common reason why the impeller cannot rotate.

⑤ Component deformation

Parts deformation caused by three blade roots blower is rare. Roots blower manufacturers rarely reduce costs through components, and the strength of components cannot reach the standard. If the thickness of the casting is too thin and the journal is too thin, if the strength of the parts does not reach the standard, the parts may be deformed, and the gap between the parts may be damaged.

Note: Roots blower The surrounding environment should be clean and tidy. Try not to let small particles fall into the roots blower impeller. If foreign matters fall into the roots blower, do not move or start the roots blower. Instead, disassemble the blower, take out the foreign matters, and reassemble it after cleaning. If you don't have professional maintenance workers around, it is recommended that you do not disassemble blindly. The quickest way is to contact the Roots blower manufacturer to guide disassembly remotely or return to the factory for maintenance.
