【摘要】 本课题采用三次设计方法，以KFB30-18型矿用风动水泵为基础，对该产品的风动涡轮系统进行了理论分析和实验研究。通过空气动力学的理论，采用复变函数的保角变换，从理论上分析了涡轮叶片的形式，导出了风动转距的解析表达式，并采用函数求级值的解析方法，求得了喷嘴的最佳安装角度，分析了风动涡轮的理论输出功率和风动效率。同时，根据风动水泵的原始参数，对水泵的效率、扬程和流量进行了理论分析计算，并进行了水轮的水力设计。在理论分析的基础上，对涡轮系统的五个主要影响因素进行了正交试验设计，通过对数据的计算与分析处理，获得了因素参数水平的最佳组合，完成了产品的参数优化设计。 最后进行了产品的容差设计。通过内、外设计的直积分析方法，分析了显著因素的误差对产品性能及稳定性的影响，建立了质量损失函数和确定了显著因素的容差。 利用本文研究结果研制的新样机性能有很大的改善。与原产品相比，新产品效率为24.30％，提高了10.75％(原泵为13.55％)，效率提高将近一倍；噪声降低到81.4，降低了4.5分贝(原泵为85.9分贝)，具有显著的技术经济效益和社会效益。更多还原

【Abstract】 The paper employs the method of three stage design to make analysis on the pneumatic turbine system of the mine pneumatic pump in theory and put it into experiment on the base of the KFB30-18 mine pneumatic pump. At first the form of the turbine blade has been analysed under the theory of aerodynamics and the angle kept tranformation of complex variable function, and thus the analytic formula of pneumatic moment has been deduced. Meanwhile the analytic approach to function extremum being employed, the optimal installing angle of the jet has been gained, and the output power as well as the pneumatic efficiency has been analysed. At the same time ,according to the original parameter of pneumatic pump, the efficiency and flux of the pump have been theoretically amalyseed and calculated, and after that the waterpower of the water wheel has been designed. And then five main factors of the turbine system have been designed under the orthogonal test. The optimal assemblage of the parameter has been gotten by calculating and analyzing the data, thus the parameters of product have been optimized.At last The toleramce design has been fulfilled with the method of inner and outer design integral analyse, the effect of the clear factors on the characteristic and stability of the product has been studied , through which the qulity losing function has been established, and the toleramce of the clear factors have been made sure .The characteristic of the new product designed to the results of our research have been improved a lot. In contrast with the old product, the efficiency has been improved by 10.75% (the old is 13.55%), nearly twice as much as the old; and the noise is reduced by 4.5dB (the old is 85.9dB) . The achievement will do much to technical economy benefit and social benefit.更多还原
