In order to ensure the effectiveness of centrifugal fan, the user must adjust the equipment properly, so that the centrifugal fan can play a great role in each use. In fact, to improve the use of centrifugal fan, not only to make the fan better for the environment, but also to save users some energy costs.
The regulation of the effectiveness of centrifugal fans can be carried out from two aspects. The first is about the size of the fan's air volume. If the adjustment depth is great, it is more suitable to adopt the rotational speed regulation method; if the fan output varies in a small range, so it is more reasonable to use the guide device to adjust, this method is better to help the fan complete the ventilation and air exchange process.
In order to ensure the effectiveness of the centrifugal fan, in addition to regulating the air volume of the centrifugal fan, it can also be started by controlling the speed of the centrifugal fan. Most users will choose the method of adjusting the speed of the centrifugal fan. There is also no direct relationship between this regulation and the form of the leaf.
Of course, it is better to adjust the economy of the rear bended fan with the speed regulation than the guide, and it is more obvious when the adjustment depth is large, but for the forward bending fan, when the adjustment depth is less than 70%,The economy of axial guide regulation is not inferior to that of speed regulation.
Of course, it is more economic to adjust the speed regulation of the backward curved fan than the guide regulation. it is more obvious when the adjustment depth is high. But for the forward curved fan, when the adjustment depth is less than 70%, the economy of the axial guide adjustment is not inferior to the speed regulation method.
Therefore, when we consider adopting the adjustment method, we need not only the adjustment methods obtained from different directions, but also the adjustment of the fan according to the actual situation and the environmental needs. In order to achieve the best use effect and minimum energy consumption. Of course, the size, cost, manufacturing complexity and maintenance and repair of the regulator can not be ignored.http://www.jnblower.com/
