Familiar with the working principle of centrifugal fans who are aware, for centrifugal fan, the fan is actually a high-energy-consuming equipment, from some comparative data to analyze, it consumes power resources in the occupied stone processing specific gravity is larger. In our country and the world, the energy shortage is already an undeniable fact of the centrifugal fan, the face of the growing shortage of energy, as well as high-yield, efficient face of the promotion and application of Hebei Axial centrifugal fans, energy saving has become stone production issues of common concern to businesses, there are many stone production enterprises to reduce power consumption of the fan as the current important work. Reduce power consumption in Hunan fan-made centrifugal fan, in addition to improving the efficiency of the fan itself beyond reasonable way to adjust the fan selection is the most important. Because the load of stone production process requirements will change with those changes, most fans will need frequent flow adjustment according to the host load.
