Solution to noise caused by abnormal vibration of three blade roots blower?

In general, a large noise of Roots blower is a fault, and a large noise is a large vibration. What is the reason for a large vibration?

Roots blower What causes high vibration and noise

① Anchor bolt looseness: vibration caused by coupling failure or anchor bolt looseness.

② Pipe connection failure: the pipe connection is not connected according to the normal procedure, which leads to the resonance between the pipe connection and the fan, so the noise and vibration will be particularly large.

③ Inadequate gear engagement precision: Inadequate gear engagement precision leads to greater vibration and noise of the fan.

④ Bearing failure: Roots blower will cause bearing failure if it is used for a long time, which will lead to abnormal noise of the fan.

The noise of Roots blower is mostly wind noise, with less mechanical noise and electromagnetic noise, which is difficult to solve.

Solution for large vibration of three blade roots blower:

① The foundation bolts and other fasteners are loose. Tighten the foundation bolts and level the base. If the ground is sunken, repair the ground in time.

② If there is a problem with the pipe connection and the pipe resonance is serious, then you can choose to use soft connection to reduce the vibration of the fan.

③ If the gear or bearing fails, we need to disassemble it before inspection. It is recommended to return it to the factory for maintenance. Do not disassemble it without authorization.

④ The noise problem can be reduced by using sound proof cover for Roots blower.

Daily inspection for three blade roots blower:

1. The common problem of the three blade roots blower is still an old problem, that is, the lack of oil operation, which will not only lead to gear wear, but also make the skeleton oil seal rapidly age, deteriorate, resulting in oil leakage, the fan running noise becomes louder, or the fan gets stuck, so pay special attention to the change of the oil level of the three blade roots blower.

2. The operating temperature of the three blade roots blower cannot exceed 40 ℃ under normal temperature, so its temperature should be checked frequently. If there is such a temperature requirement, the manufacturer should be informed at the time of purchase to make appropriate adjustments. Under high temperature, gear oil, skeleton oil seal and bearing are easily affected.

3. Pay attention to the bearing temperature, sound and vibration during the daily work of the three blade roots blower, and check the oil level, oil temperature, inlet and exhaust pressure, ammeter index, etc. of the oil pointer. If conditions permit, replace the gear oil one day after the Roots blower starts normally. You will find that the oil is dark yellow, black, and very viscous. This is because the oil on the bearing, the iron filings in the gearbox, and the gear oil are mixed together, which is not conducive to gear lubrication.

The above is the solution to the noise caused by the abnormal vibration of the three blade roots blower. I hope it can help you! If you have any questions, please feel free to consult: 0531-83663588
