What determines the price of axial fan?
I. Composition structure of axial flow fan:
Axial flow fan is mainly composed of air collector, impeller, front guide, after guide, diffusion cylinder, motor, six parts combined. I will not introduce the structure of the product, after all, these components must have their functions and uses.
Two, the material of axial flow fan:
Different working conditions will definitely choose different materials, different materials, the cost of the product is not the same, this problem is easy to explain, carbon steel, stainless steel, glass fiber reinforced plastic, aluminum alloy, high strength steel, so different materials, resulting in the cost of axial flow fan will be different. Today, I mainly explain the carbon steel material category, axial flow fan is mainly involved in the purpose of the carbon steel material component, impeller, has set the wind diverter before and after the diverter, diffusion tube, five major components, these five parts are one-piece and split type two kinds, one-piece material cost is low, but the processing complexity is high, the cost is higher score postures processing; Split type material cost is high, because the material involved in the link increases, but the difficulty of processing is weak, so the processing cost is lower than the integral, whether it is integral or split, the overall cost will not differ too much, because the assembly cost of split type is slightly higher than the integral. So there is no obvious difference between the basic structure and cost. Another problem is the choice of carbon steel material, positive material, secondary material, cold plate, hot plate, different materials, the price will be up and down.
Iii. Motors used according to working conditions:
At present, the operating conditions of axial flow fan that I understand are generally divided into: general ventilation and ventilation general motor; High temperature resistant motor; Moisture-proof motor with wet working condition; Explosion-proof motor under inflammable and explosive conditions. These four main types, perhaps there are other types, but I have little knowledge, only understand this kind of condition.
Four, the main components of axial flow fan blade:
Many fan manufacturers, its core technology lies in the blade, the blade is also known as the moving blade, it plays a decisive role in the fan structure, the size of the blade, curvature radian, the thickness of the plate, the size of the hub, simple understanding: the area of the blade determines the size of the air volume, speed determines the wind pressure of the fan. The higher the precision of axial flow fan components, the lower the flow loss, the higher the efficiency.
Combined with the above four points, such a configuration determines the cost of the axial flow fan, the material of the casing; The type of impeller and the power of the motor determine the sales price of the axial fan. So when choosing the fan manufacturer, you should clearly understand the production capacity and processing capacity of the manufacturer as well as the design and inspection strength. However, we can not only look at the price of the fan, even if the same product, different manufacturers, processing and inspection methods are not the same, the cost will be relatively different, industrial products sell is the use of the effect, rather than the price, demand is far more important than the price. See your demand to decide the price of the product!
