我矿西风井用ＺＫ６０—４Ｎ０２８型轴流风机．由绕线式电 机拖动（ＹＲ８００－１０／１１８０ 型．ｎ＝８００ｋｗ．Ｎｅ＝５９３ｒ／ｍｉｎ）．全速运转下实际功率６０２ｋｗ，由于每年有４ ０００多ｈ的交接班、夜班及检修时间可以调小风量，减少电机功率．为节能降耗，决
I mine Zifeng wells with ZK60-4N028-type axial fan. Driven by the winding motor (YR800-10 / 1180.n = 800kw.Ne = 593r / min). At full speed, the actual power is 602kw. Since there are more than 4,000 h handovers every year, the night shift and overhauling time can reduce the air volume and reduce the motor power. To save energy, decided
