Roots blower may cause a series of problems during operation, such as abnormal sound. For many times, some enterprise operating equipment personnel do not understand the situation, mistakenly think that there is a major problem in equipment maintenance, but do not know what to do. Xin Qianshun has sorted out the causes of abnormal sound of Roots blower for you, and the specific analysis is as follows:

Analysis of the causes of abnormal noise of Roots blower?

1. Impeller failure: there are many mutual friction between impellers, which is caused by many reasons, such as too much dust inside Roots blower, too long service life of bearings, and impeller failure.

2. Case use problem: the chassis produced by some manufacturers does not meet the standards, is cheap, and has a long service life, which may lead to deformation of the chassis, resulting in friction between the impeller and the chassis.

3. Use of bearing: there are four impellers working in the bearing. If one of the bearings is faulty, the whole impeller will be in a failure state and will not work. Improper use of bearings Serious system faults may directly lead to fan locking, and minor faults may lead to the squeak of roots blower.

4. Sealing failure: the sealing failure of roots blower is related to the reduction of air flow. Failure of the seal may lead to gas leakage and may cause the roots blower to make a squeaking sound.

5. Pipe blockage: the fan outlet is not smooth, and the air cannot be discharged. The increase of the pressure will cause the motor overvoltage to exceed the rated load, which will lead to the rise of the Roots blower ammeter, causing the Roots blower to gurgle.

6. The reason for lubricating oil: the roots blower is not smooth when it is running at the outlet, so it can not exhaust air, which causes the pressure to rise constantly, and the motor can generate system overvoltage and overload, which in turn affects the rise of the roots blower ammeter, thus causing the roots blower to make a gurgle.

7. Operation error: current overload may also cause operation problems. For example, when installing a check valve, let the check valve start to operate before all gate valves open. This improper operation may cause the current to rise instantaneously, the motor will not work instantaneously, and the motor will be burned out. The operation shall be carried out in accordance with the specified operating regulations of Roots blower, and no unnecessary trouble shall be caused due to carelessness, which may lead to failure.

8、 Roots blower Self quality problems: factory products have their own problems. During installation, for example, the clearance of the impeller and other components is poor, which may lead to increased additional friction. Some components may be damaged, which will increase the load of the motor and cause the motor current to increase, thus burning the fuse.
