Tips And Characteristics For Selecting Blowers

Blower is the most commonly used type of machine at present. When we purchase, we must pay attention to the following elements. The saying goes, "goods are better than three houses". Everything needs to be understood in many directions, so that we can know the real value of things. The same is true for buying fans. One look, two touch, three comparison. The main points of this issue are to introduce the following three elements when we talk about buying blowers.

First of all, "look," we must look at the appearance, even a product that is not beautiful. It is certainly not a good product. The precision of the blower mold used is not high. Although the appearance is exquisite, it does not mean that the quality is perfect, but the perfect quality of the fan must be beautiful.

Next is "touch". When you choose the fan, you might as well touch the surface of the fan with your own hands to see if it is tied up, whether the color is uniform or not. If there is any defect in the welding link, rotate the fan blades with your hands to see if the balance is perfect or not.

Finally, it is "contrast", which is to choose which kind of blower, and depends on what kind of blower you need. It can not be cheap and can't be used to buy it. It's still your own needs. According to your needs, what functions do you need, how much wind pressure you need, how much air pressure you need, or how little noise you need to choose.

The characteristics of the blower are as follows:

The blower has no friction due to the impeller running in the body and does not need lubrication, so that the discharged gas is free from oil. It is an ideal source of pneumatic conveying for chemical industry and food industry.

The blower is a volume operated blower. When used, the flow rate changes very little with the change of pressure. But the flow varies with speed. Therefore, the choice of pressure is wide, and the choice of flow can be achieved by selecting speed.

The speed of the blower is high, and the clearance between rotor and rotor, rotor and body is small, so the leakage is small and volume efficiency is high.
The structure of the blower determines that its mechanical wear loss is very small. Because only bearings and gear pairs have mechanical contact on material selection, rotor, casing and gear ring have sufficient mechanical strength. Safe operation and long service life are major features of blower products.
The rotor of the blower is checked by static and dynamic balance. The finished product runs smoothly and vibration is minimal.
The blower with the above characteristics mainly includes roots blower, side flow fan and multi-stage centrifugal blower.
