气垫带式输送机专用风机的研制

阐述了现行国内气垫带式输送机设计选型时,供风系统主参数与选用风机参数匹配不合理,使风机运行在低效区的现象;应用模糊评判方法计算供风系统主参数,得到供风系统主参数及关系曲线;应用直方图分析法确定供风系统所需风机的比转数;进行了气垫带式输送机专用风机的设计,并对研制的专用风机样机进行了空气动力性能试验和现场工业试验。

There exists unreasonable parameter matching problem between air supply system and the selected blower in design and selection of existing air cushion belt conveyors, which results in blower＇ s running in low efficient operation area. The main parameters of air Supply system are obtained and the relation curve is plotted with fuzzy justification method. The frequency values varying with rotation ratios are plotted and the desired rotation ratio is determined. The special blower for air cushion belt conveyor is designed and air kinetics performance test and field industrial test of the designed blower are conducted.
