Many people Roots Blower I don't know much about it, so I always feel helpless when Roots blower breaks down. Today, I will take you to understand the fault analysis of Roots blower gear

1、 Bearing damage

Bearing damage will also cause the gear to stop rotating. Bearing is an important part of Roots blower. Each head of Roots blower has four bearings, which are placed at both ends of the impeller shaft. Bearing damage, on the one hand, may cause the impeller to jam, on the other hand, may cause gear mesh error. Therefore, this will also cause the gear not to rotate.

2、 Rotor shaft damaged

The rotor shaft is part of the impeller and runs through the horizontal shaft of the impeller. Some of the rotor shafts of the impeller are integrally formed, and some are assembled. The wear and deformation of the rotor shaft will affect the rotation of the impeller and the rotation of the gear.

3、 Unreasonable gear meshing When installing the gear, there is a certain clearance error. If the meshing clearance is too small, the gear will not rotate. There are many clearance standards for Roots blower assembly, which need to be adjusted according to the design regulations.

4、 Positioning hole dislocation

After the Roots blower is overhauled, such as the replacement of impeller and shaft, it may involve inaccurate positioning of the gear sleeve. If the gear sleeve is inaccurate, it is necessary to re design the positioning hole according to the gear. If the positioning is not correct, install the gear, and the gear may not rotate.

5、 Impeller stuck

The impeller of Roots blower is damaged. The gear and the impeller are in two chambers. The reason for the gear damage may be the fault in the gearbox or the impeller fault. If the impeller is not checked, the gear will not rotate after the installation of the gear, which may be the impeller fault.

The above is the reason why the gear of Roots blower does not rotate. I hope it will be helpful to everyone.
