First of all, the axial flow will be used. In simple terms, the axis flow is consistent with the working principle of the general home fan.The difference between household fans and axis flow lies in the wind pressure. The use of shaft flow is generally under the condition of wind pressure below 490Pa.
1. The composition structure of the axial flow fan:
The axis fans are mainly composed of a gauze, impeller, front derivatives, rear guide, diffusion cylinder, and motor. Most of the six are combined.
Second, the material of the axis fans:
Different use of working conditions, they will definitely choose different materials, different materials, and different costs made. This problem is easy to explain.Different materials will lead to different costs of the axis fans.Today, the category of carbon steel is mainly explained. The main components involved in the use of carbon steel in the shaft fans include air collector, impeller, front derivatives, rear guide, diffusion cylinders, 5 major parts.There are two types of components: integrated and split -type. The cost of all -in -one materials is low, but the complexity of processing is high. The cost is higher than that of the split type.Therefore, the processing cost is lower than that of all -in -one. Whether it is integrated or split, the overall cost will not be much different, because the assembly cost of the split type is slightly higher than the all -in -one.Therefore, the basic structural cost differences are not obvious.Another problem is the choice of carbon steel, genre, secondary materials, cold plates, hot plates, different materials, and the price will have a upper and lower amplitude.
Third, the main component of the axis flower:
There are many fan manufacturers. Its core technology is wind leaves. Wind leaves are also called dynamic leaves. It plays a decisive role in the fan structure.The area determines the size of the air volume, and the speed of speed determines the wind pressure of the fan.The higher the accuracy of each component of the axis, the lower the losses, and the higher the efficiency.
Combined with the above three explanations, this configuration determines the cost of the bearing fans, the material of the case; the type of the impeller, the power of the motor determines the sales price of the bearing fan.So when choosing a fan manufacturer, you must clearly understand the manufacturers production capacity and processing capabilities and design inspection strength.However, we cannot look at the price of the fan alone. Even if the same type of products, different manufacturers, different processing methods and inspection methods, the cost will be relatively different. Industrial products are sold on the use effect, not price, demand is far from the price than the price.important.
