Chengdu Roots Blower Factory: The reason why Roots Blower cannot rotate

Category： Industry Information

time：2022-10-27

　　Chengdu Roots Blower FactoryLet's talk about the reason why the Roots blower can't rotate.

Recently, a customer asked, found that the roots blower can't turn, what should I do, this is how to return a responsibility? Please don't worry, try to disconnect the switch power supply, terminate the operation, carry out matching maintenance, open the reserved roots blower together to prevent unnecessary trouble, the following is a collection of 7 factors, please accept the reservation.

1. Roots blower is stuck by hard objects

Coarse particles enter the fan cavity, hindering the gap between components, causing the Roots fan to rotate. This requires cleaning up the dirt in the inner cavity and checking the gap between the centrifugal impellers. It is also necessary to inquire the main reason why dirty things fall in to avoid common failures again.

2. Roots blower centrifugal impeller damage

Centrifugal impellers destroy the fan and are not easily turned over. This type of destruction is well understood. The teeth between the centrifugal impeller and the impeller bite each other, and the fan does not move due to the destruction of the centrifugal impeller. This type of common fault must be disassembled and query the housing.

3. Roots blower drive gear damage

Normal transmission gear blockage area is about 2/3. And beyond the teeth bite area, the bite force between the transmission gear is very large, resulting in the transmission gear can not rotate, which in the end caused the fan rotation.

4. The rolling bearing of Roots blower is damaged

Roots blower has 4 rolling bearings. If the rolling bearing is destroyed, it may cause the gap between the centrifugal impeller and the impeller, the waterproof casing and the plate wall to change, and the centrifugal impeller friction will make the fan rotate, which is also the subjective factor of the centrifugal impeller gap change. That's also the common reason why Roots blowers can't turn.

5. Rust stuck

Roots blowers have long been put on hold for a long time, and both inside and outside will rust. The centrifugal impeller is embroidered with a board wall or casing; or the rust falls off on a large scale, and the centrifugal impeller may be stuck. In this case, use gasoline bubble immersion, car gasoline cleaning to clean up the rust, and adjust the gap.

6. Deformation of Roots blower components

　　Chengdu Roots Blower Factory: The deformation of parts caused by Roots blower is rare. A few manufacturers have reduced costs and the compressive strength of parts cannot meet the specifications. The same type of Roots blower may have casting thickness.

If the compressive strength of the parts is not very high, the deformation of the parts may occur, and the gap between the components may be damaged, causing the fan to jam. If the goods are placed for a long time, it will also cause some deformation of the components.

7. Motor damage

If the Roots blower shows a motor problem, the motor cannot rotate, and the Roots blower will naturally not rotate. If the motor problem is solved, repair and replace the motor.
