Advantages and disadvantages of backward tilt centrifugal fan

The backward curved fan has many advantages, but also has some defects. Therefore, in the specific work, we must analyze its key advantages and defects, in case the selection is not correct. So, compared with other similar equipment, what are the advantages and disadvantages of backward tilt centrifugal fan?

First of all, give you a detailed introduction to the specific advantages of backward tilt centrifugal fan.

1. The equipment has high working efficiency, and its output power graph shows no load condition. This is because the key aggregation of its output power curve can reach a large value within the common range, so it is not easy to overload;

2. The blade and impeller of the equipment have high structural strength, so it can be applied to high static pressure system;

3. In the conventional working process, the backward tilting centrifugal fan can ensure a large exhaust air volume, and the noise sent is not large, which is not easy to cause excessive harm to the natural environment of the construction site;

4. Its high efficiency area is wide, and its operation can be changed by changing the static pressure.

Because the equipment in the operation process, the impeller inside will be at a higher speed, so we must use a thicker shaft and larger bearings as a support point, and it has higher provisions for stability; In addition, if the static pressure fluctuates, it is easy to cause changes in working conditions.

In addition, if there is turbid air in the environment, it is not recommended to use a backward tilt centrifugal fan to prevent dust deposition. And if the backward tilt centrifugal fan uses the airfoil blade, its working performance is not very stable, and it is easy to suffer from corrosion.
