What problems may occur during the operation of Roots blower

Roots blower is simple in structure and easy to manufacture. It is very suitable for gas transmission and pressurization in low pressure occasions, and can also be used as a vacuum pump. In recent years, Roots blower has been widely used in aquaculture, sewage treatment, pneumatic transmission, power generation and other industries.

The maintenance difficulty of Roots blower is to adjust the clearance between two impellers, between impellers and casing, and between wallboards at both ends, so that the blower can operate normally. If the clearance is too large, the gas leakage will be large and the fan performance will decline; On the contrary, if the clearance is too small, equipment accidents may occur during operation due to different thermal expansion dimensions of casing and impeller.

Roots blower will produce high noise during operation. It is characterized by high sound level, wide frequency band and prominent low frequency, so it spreads far away and affects the physical and mental health of operators. Generally, factories only install silencers without integrated control.

1. Very noisy.

If the Roots blower has been used for a long time, the overall compactness will be reduced after a long time, the anchor bolts will be loose, the muffler will be aging, and the gap deviation between the parts will increase, leading to the increase of the noise of Roots blower.

2. The working pressure decreases.

The key reason for reducing the working pressure of Roots blower is that the clearance between centrifugal impellers, between centrifugal impellers, between centrifugal impellers and plate walls, and between centrifugal impellers and shells increases. Roots blower is a mechanical equipment for forced steam transmission. The working pressure displayed by Roots blower is the friction resistance in front of it, commonly known as condensing type. The expansion of the gap will cause serious steam backflow, resulting in the reduction of air pressure and working pressure.

3. The air displacement is small.

What problems may occur in the operation of Roots blower

There are many reasons for small exhaust air volume and large clearance of Roots blower. If the gap increases, the internal leakage is serious, and the exhaust air volume will be reduced. Similarly, in the whole process of transporting steam, if the pipeline leaks, it will also reduce the exhaust volume.

Small exhaust air volume may also be caused by pipe blockage, which is generally high pressure and high temperature distribution. In order to avoid pipe blockage, it is necessary to maintain Roots blower regularly.

I believe that after reading the above contents, you should also have an understanding of what problems may occur in the operation of Roots blower. I hope it will be helpful to you.
