Overview of FansIn many industries and in our everyday life different fans find use. Fans are intended to cool equipment, ventilate premises, to generate directed flows of air. By their intended purpose fans are divided into fans and coolers, which consist of fans combined with heat exchangers.By their construction, fans are divided into axial, radial centrifugal and diametral tangential ones.Now let's briefly summarize the information about the structure of a fan. A fan is a rotor with blades attached to it in a certain way. It is usually enclosed in a metal or plastic casing, a frame, which also serves as a tunnel in axial fans, and is also a holding element. The dimensions of the frame determine the dimensions of the fan. The frame thickness (the length of the tunnel) determines the delivery of the fan. Ie, the thicker the fan is, the better is its delivery, all other parameters being equal.In contrast to axial fans, blades of diametral fans are located in accordance with the squirrel-cage principle: the rotor is hollow in the center and blades are located on the periphery.The main characteristics of fans.The characteristic of the overall dimensions of a fan determined by its frame goes first. Then - the characteristics of operating voltage and current, direct or alternating. Power consumption, using which we can determine the maximum allowable operating current in order to avoid the fan burnout, and the bearing type. It should be noted that the fan noise level and its ...
