What determines the price of an axial fan?
What are the main components of industrial axial and centrifugal fans? The difference between household fans and axial fans is the wind pressure of the fan, and the working conditions of the axial fans are generally lower than 490Pa.
First, the composition of the axial fan:
the axial fan is mainly composed of a collector, impeller, front deflector, rear deflector, diffusion cylinder, motor, and six major parts are combined. For the structure of the product, I will not introduce them one by one, after all, these components must have their role and use.
Second, the material of the axial fan:
different use conditions need, will definitely use different materials, different materials, the cost of the product made is not the same, this problem is easy to explain, carbon steel, stainless steel, fiberglass, aluminum alloy, high-strength steel, so different materials, resulting in the cost of axial fans will also be different.
Today I mainly explain the category of carbon steel materials, axial flow fans in the use of carbon steel materials mainly involved in the components are wind collectors, impellers, front deflectors, rear deflectors, diffusion cylinders, 5 major components, these five components have one type and split type two types, integrated material cost is low, but the processing complexity is high, the cost is higher than the split type processing;
the cost of split type materials is high, because the material involved in the link is increased, but the processing difficulty is weak, so the processing cost is lower than the integrated type, whether it is integrated or split type, The overall cost will not differ too much, because the assembly cost of the split type is slightly higher than that of the one-piece type. Therefore, the basic structural cost difference is not obvious.
There is also a problem is the choice of carbon steel materials, genuine materials, secondary materials, cold plates, hot plates, different materials, the price will be up and down.
Third, according to the working conditions of the use of the motor: At present, the working conditions of the axial fan that I understand are generally divided into: general ventilation and ventilation of ordinary motors; high-temperature resistant motors; moisture-proof motors with wet working conditions; explosion-proof motors under flammable and explosive conditions. There are four main types, and there may be other types, but I am shallow and only understand this kind of working conditions.
Fourth, the main components of the axial fan blade: there are many fan manufacturers, its core technology lies in the wind leaf, the wind leaf is also known as the moving leaf, it plays a decisive role in the fan structure, the size of the wind blade, the twisting arc, the thickness of the plate, the size of the hub, simple understanding: the area of the wind leaf determines the size of the air volume, the speed of the speed determines the wind pressure of the fan. The higher the accuracy of the components of the axial fan, the lower the flow loss and the higher the efficiency.
Combined with the above four points, such a configuration determines the cost of the axial fan, the material of the casing, the type of impeller, and the power of the motor determine the sales price of the axial fan.
Therefore, when choosing a fan manufacturer, you must clearly understand the manufacturer's production capacity and processing capacity and design inspection strength.
However, we can not look at the price of the fan alone, even if the same type of products, different manufacturers, processing methods and inspection methods are not the same, the cost will be relatively different, industrial products are sold is the use of the effect, not the price, the demand is far more important than the price. It depends on your needs to determine the price of the product!
