Causes and solutions for insufficient air volume of Roots blower in normal use:

Although Roots blower is tough, it also needs careful maintenance. If it cannot be used and maintained correctly, it is also prone to failure. What Renze shared in this chapter is that the air volume is insufficient during fan operation, and the solutions are as follows:

1. The inlet filter is blocked. The bad environment on the site where the fan is used will cause the filter to absorb a lot of foreign matters. If it is not cleaned in time, the filter will be blocked. The air volume will be reduced and the pressure will be increased due to blocked air intake. The solution is to clean the filter and replace the filter screen if necessary

2. The belt will loosen after being used for a long time, and the V-belt will slip, so you only need to replace it with a new one

3. There is a break in the pipe and air leakage occurs. The air volume can be recovered by repairing the pipe

4. Foreign matters fall into the housing of Roots blower, the impeller is worn and the gap increases, resulting in insufficient air volume. It is necessary to return to the factory for impeller repair. At the same time, check whether there is abrasion in the housing, and repair it if necessary
