【摘要】 本文综述了国内外矿用通风机的现状、发展趋势和存在问题,在分析了轴流式通风机和对旋轴流式通风机空气动力性能特征和结构的基础上,提出研发一种安全性好、可靠性高、气动性能可以调节、高效率和低噪声的矿用双转速对旋轴流式局部通风机。根据普通轴流式通风机和对旋轴流式局部通风机空气动力理论基础,在分析了各部分结构对空气动力性能影响的基础上,采用综合分析研究方法,对各部分结构进行了优化设计,联合电动机厂研发成功专用双转速隔爆电动机,通过自己编制的计算软件进行通风机空气动力设计计算。根据设计和分析的结果,制造了试验样机。通过对样机的空气动力实验和工业性试验研究表明,该通风机研发是非常成功的。一台通风机有四种不同的转速配对方式,有四种空气动力性能参数,能满足掘进巷道前中后期对风量和风压的要求,可以实现按需供风。通风机具有高风压、大风量、高效区宽、噪声低和空气动力性能可以调节的优点,能很好地解决煤矿巷道掘进中前、中、后期按需通风的问题,具有广阔的市场前景。更多还原

【Abstract】 This paper summarized the actuality, development trend and existing problems of the mining fan. Based on the analysis of the air dynamic performance characteristics and the structure of the Axial-flow fan and the contral-rotaring Axial-flow fan, the paper puts up the Dual-Velocity Contral-rotaring qxial fan for mining which has high security, reliability, adjustable air dynamic performance, great efficiency and lower noise.Based on the air dynamic theories for the general Axial-flow fan and the contral-rotaring Axial-flow fan, the paper first analyzes the air dynamic performance influence from each structure then synthetically analyzes and optimizes the design of each structure. Associated with the electromotor factor we succeed developed special electromotor for separating explosion. The paper designs and computes fan air dynamics through computing software made by the author.The experiment of sample machine shows that it is great successful to develop the fan. A fan can have multiple different rotate speed partnership modes and have multiple air dynamics performance parameters, which can satisfy the request for the wind quantity and wind pressure during each phase of mining laneway and can supply wind according need. The fan is provide with great wind pressure, great amount of wind, commodious high efficiency area coverage and lower noise, which can well settle the far distance ventilation problems during moving forward in the coal mine laneway and thus can hold great market future.更多还原
