How to solve the problem that the Roots blower cannot operate normally due to the shutdown during the epidemic in 2022?

In the Spring Festival of 2022, due to carbon reduction and emission reduction and local epidemics, many enterprises are in a dilemma of stopping production, and plant equipment cannot operate normally. Many mechanical equipment stop working for a long time, resulting in abnormal operation after returning to work. Roots blower equipment is a more typical one. For this reason, Xinqianshun makes the following analysis and summary on the phenomenon that Roots blower equipment cannot be started normally due to long-term shutdown after the resumption of the enterprise, for your reference. If there is anything wrong, please correct it.
The reason why Roots blower cannot operate is that there are electrical circuit faults, motor faults, foreign matters falling into the cylinder, the rotor is rusted and stuck, foreign matters are found in the gear meshing part, and the pipeline resistance at the outlet of blower is too large.

What is the reason why Roots blower cannot rotate normally? It is a serious fault that the Roots blower cannot rotate normally, which may be caused by problems such as large particles stuck in the fan wall, blocking some gaps, the fan is stuck and does not rotate, the gear is damaged and the meshing pressure is too large.

Roots blower rusts and gets stuck. Roots blower has been idle for a long time, and rust will appear inside and outside. The impeller is embroidered with the wallboard or casing; Or the rust falls off in a large area, which may lead to seizure between impellers. In this case, the rust shall be cleaned by means of kerosene immersion, gasoline washing, etc., and the clearance shall be adjusted.

It is rare that the three blade Roots blower can not rotate due to the deformation of parts and components. A small number of Roots blower manufacturers blindly reduce costs, resulting in substandard strength of parts and components. The Roots blower with the same model and low price is likely to have thin casting thickness and thin journal, If the strength of the parts is not up to the standard, the parts may be deformed, and the gap between the parts may be damaged, resulting in the fan being stuck. In addition, if the product is placed for a long time, it will also cause certain deformation of parts.

1. The gear is damaged

The meshing area of normal gears is about 2/3, and if it is larger than this, the meshing force between gears is too large, which causes the gears to fail to rotate, thus causing the fan to fail to rotate.

2. Rust jamming

Roots blower has been idle for a long time, and rust will appear inside and outside, and the impeller is embroidered with the wallboard or casing; Or the rust falls off in a large area, which may lead to seizure between impellers. In this case, the rust shall be cleaned by means of kerosene immersion, gasoline washing, etc., and the clearance shall be adjusted.

3. Foreign matter is stuck

There are large particles entering the fan cavity, blocking the clearance of each part, causing the fan unable to rotate. This requires cleaning the foreign matters in the cavity and checking the clearance between impellers. In addition, check the cause of foreign matter falling in to avoid reoccurrence of the fault

4. Impeller damaged

The impeller is damaged. The fan is stuck and can't rotate. This kind of fault is easy to understand. The impeller and the impeller occlude each other, causing the impeller to not rotate. This kind of fault requires disassembly and inspection of the casing.

5. Bearing damage

There are 4 bearings on Roots blower. If the bearing is damaged, the clearance between the impeller and the impeller, the casing, and the wallboard will change. The friction of the impeller will cause the fan to fail to rotate. This is the indirect reason for the change of the impeller clearance and the common reason for the impeller to fail to rotate.

6. Parts deformation

It is rare that the roots blower can not rotate due to the deformation of parts and components. A small number of roots blower manufacturers blindly reduce costs, resulting in the strength of parts not up to standard. The roots blower with the same model and low price is likely to have thin casting thickness, thin journal, etc. If the strength of parts is not up to standard, the parts may be deformed, The clearance between parts is damaged, causing the fan to be stuck and unable to rotate. In addition, if the product is placed for a long time, it will also cause certain deformation of parts.

7. Motor damage

If the Roots blower has been idle for a long time, if there is a motor fault, it will naturally become immovable. It is easy to judge the fault. If the motor cannot rotate, the fan will not rotate naturally. If the motor has a fault, the motor of the fan should be checked, and then the fault should be eliminated.

I believe that after reading the above contents, you should also have some understanding of the causes of the failure of Roots blower to operate normally. I hope it will be helpful to you.
