The quality of Roots blower is related to many factors. The fan price is quoted according to the model parameters, power and material. Now there are more and more wind turbine manufacturers in the market. Some wind turbine manufacturers use "price war" to attract customers, but they do not focus on quality. There are many fan manufacturers, but most of them are small in scale. To select high-quality rotary blower manufacturers, we should start with their processing strength. The products of good fan manufacturers are precision processed and manufactured by the processing center. Next, we should look at their standard accessories. Good manufacturers use well-known brands at home and abroad. Then we need to look at the cooperation unit of the manufacturer. The user's use case is a strong proof of the quality of the manufacturer.
Among the commonly used methods of Roots blower, surfacing is used more often, and the effect is acceptable. Generally, it can be used for more than one year without extensive repair. Its disadvantage is that a large amount of heat is input by surfacing, which will lead to deformation of the impeller if not well controlled, and it cannot be repaired and used repeatedly. Thermal spray welding also has the same problem, which greatly limits their application. At present, a better method is to paste or inlay wear-resistant ceramics on the convenient surface of the impeller volute, because wear-resistant ceramics have good wear-resistant performance, which can greatly improve the wear-resistant performance of the fan.
The trial operation of Roots blower with double oil tanks and low noise is different from that of ordinary fans. The parts of double oil tanks should be carefully inspected to ensure the integrity and availability of parts.
1. Double oil tank roots blower, check whether there is oil leakage in the oil tank, if there is, repair it in time, and check whether the oil volume in the oil tank is within the normal range.
2. Check the internal conditions of roots blower, check whether there are sundries in roots blower, and clean them in time if there are any.
3. Check the integrity and smoothness of roots blower impeller.
4. Check whether various spare parts of Roots blower are complete, such as pressure gauge, bolts, etc.
5. During the trial operation of roots blower, it must be operated under no-load condition.
6. After the commissioning, the roots blower must be installed correctly and firmly on the horizontal plane.
7. Test the noise value of roots blower during trial operation to ensure that the noise value of roots blower is within the controllable range.
8. During the trial operation, it is necessary to record various operation indicators and make corresponding records.
I believe that after reading the above contents, you should also understand the precautions during the commissioning of Roots blower. I hope it will be helpful to you.
