1. Rusty and stuck

If the Roots blower is idle for a long time, the inside and outside will rust, the iron column will fall off in a large area, and the impeller will get stuck. In this case, it will rotate if it needs to be soaked and rinsed with gasoline, diesel, and dilute materials.When the rotation is very loose, turn on the power to work normally.

2. Enter the foreign body and be the owner of the card

Large particles enter the Roots fan, blocking the gap between the parts, causing the Roots fan to not rotate. At this time, the foreign objects need to be carefully removed to avoid the particles from breaking, and check the gap between the impellers.At the same time, check the cause of the foreign body falling into it so as not to fall into the foreign body again. After turning it easily by hand, turn on the power supply to work normally.

3. Deformation of parts

Due to long-term use, the wet-effect reaction of the Roots fan components will cause the parts of the Roots fan to deform, but this is rarely the case.
