摘要
针对矿用引风机叶片磨损快、寿命短、维修费用高的实际情况，从纵横两个剖面研究磨损机理，建立了横剖面的磨损公式。提出了变质量叶片。使用表明，变质量叶片使得叶轮的使用寿命提高了５倍左右，节约了大量的维修费用。
In view of the fact that the wear and tear of the vane of the draught fan wear quicker and the expenses of maintenance is expensive. This paper studies the principle of wear and tear from the vertical and cross section, sets up the cross section wear formula, puts for- ward variable vertical section quality vane, improves the life of vane, cuts down the expense of maintenance.
