What factors will affect the clearance of Roots blower? Processing precision: some small manufacturers have imperfect processing equipment or inferior processing equipment, so it is difficult to guarantee the precision of parts after processing. Only the parts processed with precision equipment can be qualified, and the clearance between parts can be standard after installation. This is only one aspect, and the key point of affecting the clearance is still the material, because even if the machining accuracy is enough and the material of the accessories is poor, the clearance will also be affected after the fan is running.

What are the clearance standards of Roots blower? During assembly inspection, the following clearances will be inspected:

1. Clearance between impeller and casing;

2. Clearance between impellers;

3. Clearance between impeller and tooth end wallboard;

4. Clearance between impeller and drive end wallboard;

5. Clearance between gears;

Roots blower is assembled and delivered from the factory. If there is a large error in the clearance, it will also be rectified. Then it will be tested again, assembled and shipped. If you want to know about factory assembly, you can click here.
