How to Adjust Mine Axial Fan to Save Energy

Mine axial flow fan needs to be adjusted before it is normally put into use. The main purpose of adjustment is to better meet the needs of coal mine projects. Many coal mining enterprises choose axial flow fans for mining, on the one hand, to speed up the speed of coal mining, on the other hand, to ensure the safety and health of the working environment of miners on the premise of energy conservation and safety. So the main content we share with you today is how to adjust the mine axial fan to save energy.

1. When the speed regulation range is determined, attention should be paid to the mechanical critical speed of the unit, otherwise the unit may be damaged when the speed withers to the resonant frequency.

2. The characteristics of the withering speed device are as consistent as possible with the load characteristics of the mine axial fan, otherwise the effect is not ideal.

3. The speed change of mine axial flow fan should not be too large, the 1 speed should be between 70% 1 100%, and the minimum speed should not be less than 50% of the rated speed. Because when the rotating speed is lower than 40% 1 50%, the efficiency itself is obviously reduced, which is also uneconomical.
