Coal mine main fan is one of the largest-power-consuming facilities among various electrical and mechanical equipments, its power consumption usually accounts for 20% ~ 30% of the total. If a few percentage points can be lowered in its energy consumption, energy efficiency will be very substantial. One main reason for the main fan's high power consumption is its overall low efficiency. After a long time operation, most of the coal mine fans' impeller, intake air box, air inlet and chassis have a serious corrosion, which is a main threat to the safe operation of fans, and also increases the running resistance, less efficiency, thus can not meet the actual on-site demand. Therefore, performance optimization of the fan to reduce power consumption is imperative. A set of technical improvement program that focuses on saving energy and increasing efficiency is designed on the basis of surface anti-corrosion.
