For some relationships between different flows, we divide the adjustment method into several different methods, that is, the adjustment method has a small impact on the energy saving effect. Even because the existence of the adjustment device is not only energy -saving, it consumes more work. The transmission adjustment curve is close to the ideal curve. Therefore, the frequency conversion speed adjustment method is relatively superior, especially the energy saving solution for using the frequency conversion motor speed adjustment, but the tunnel fan needs to increase the inverter device.

Adjusting the fan is to make the wind pressure or air volume of the tunnel fan and control the fan manually. Through effective adjustments, the fan can not only meet the requirements of production of traffic or pressure, but also to a large extent saving energy. Although users use different adjustments, they have achieved the same goals, but they have different effects.

The choice of adjustment method not only has the effect of tunnel fan, but also has a great impact on the energy conservation of the fan. Therefore, choosing a suitable adjustment method can achieve energy -saving effects on the premise of maintaining the same effect of the fan. Only in this way can we improve the efficiency of the fan, achieve high energy saving, better protect the tunnel fan, and extend the efficiency of use.
