Analysis of the rotor clearance problem of Roots blower for powder conveying

The rotor clearance of Roots blower for powder conveying has clear specifications. There are problems with the gap between the rotor blades and hinges, and the gap between the blades and hinges changes during operation. The two rotors will collide when rotating at low speed, causing friction or even jamming between the rotors.

Once this mechanical failure occurs during operation, the two rotors or the rotor and the casing will collide, emitting a strong impact sound; the vibration will become larger, and it may even cause the foundation to vibrate; at the same time, the temperature of the friction part will rise in a short time, and even the casing will heat up and burn red. Therefore, the gap of the Roots blower must be adjusted properly, and generally an experienced master is required to assemble it during installation.
