Mixed flow fans are widely used in industrial and mining enterprises and high and civilian buildings. The utility model has the advantages of relatively large air volume, relatively high wind pressure, and capable of mounting along the bearing direction, etc. the mixed flow fan has less noisy noise, less power consumption, high efficiency, wide area of action, safe and reliable use, and safe operation and reliable advantages.
How to choose the mixed flow fan when it is used? Now let's briefly introduce the selection of SWF series Francis fans.
SWF series mixed flow fan Considering the possibility of air leakage in the piping system, some resistance calculations are not accurate. In order to run reliably, the air volume and wind pressure selected should be larger than the calculated air volume and wind pressure of the ventilation and dust removal system.
1. mixed fan manufacturers choose the type of fan on the fan product sample according to the air volume and wind pressure selected, determine the fan number, speed and motor power.
2. the operating point of the selected fan should be in the economic range, preferably on the right side of the highest efficiency point.
3. in order to facilitate takeover and installation, it is necessary to choose the proper outlet position and transmission mode of the fan.
