What is the difference between a Forward Centrifugal Fans and a backward centrifugal fans
What is the difference between a Forward Centrifugal Fans and a backward centrifugal fans?
Many people do not understand the meaning of forward and backward inclination of centrifugal fans. In fact, they are mainly called by different blades of the assembled fan. Although there is not much difference on the surface, when purchasing a fan, please refer to it. This factor can make the fan more fully perform its functions. Therefore, Hangzhou Aifuluo Electric Co., Ltd. will explain this knowledge in detail for you, come and take a look.
The Forward Centrifugal Fans is generally a blower, and the backward-inclined type is an induced draft fan. The difference is the length of the impeller rail and the edge of the impeller. The forward inclination is parallel to the edge of the impeller, and the outlet angle of the impeller is greater than 90 degrees. For the forward impeller, the forward impeller is mostly high pressure. The backward tilt and the impeller are not parallel, and the length is a few centimeters or several millimeters from the edge of the impeller. It means that the exit angle of the impeller is less than 90 degrees. The backward tilt impeller is also called the backward impeller. The backward impeller is mainly based on medium pressure. The difference is mainly manifested in the following three aspects:
1. Noise: The running noise of the forward tilting type is greater than that of the backward tilting type.
2. Power consumption: Since the efficiency of forward-tilted equipment is lower than that of backward-tilted equipment, its power consumption is greater than that of backward-tilted fans.
3. Power: The static pressure head used to overcome the resistance of the system, the Forward Centrifugal Fans is smaller than the backward-inclined type. Since the channel in the backward inclined blade fan is gradually enlarged, its hydraulic loss is smaller than that of the forward inclined fan. Therefore, the efficiency of the forward-leaning type is lower than that of the backward-leaning type.Related Reading:more products
