利用均匀试验设计优化矿用风动水泵风动涡轮系统结构参数

 根据矿用风动水泵在使用过程中效率低的问题，采用了均匀设计试验法优化水泵的性能，用均匀设计表安排了风动水泵风动涡轮的叶片弦高和喷嘴角度对性能影响的试验，经回归分析得到了最佳的试验结果。用单因素试验法分析了诸因素对性能的影响规律，对于涡轮系统的参数选择在综合考虑各影响因素的情况下，重点考虑喷嘴角度和叶片弦高的影响，其中喷嘴角度对水泵性能影响最大，试验最终获得良好效果。表明均匀设计试验法是安排多水平试验的良好方法。

The U-D Design on the Pneumatic Turbine System of Mine Pneumatic Pump

Aimed to solve the low efficiency of mine pneumatic pump, this paper employs uniform distribution and experimental design to optimize the performance of pump. Using the U-D design the experiments for the blade chord height and nozzle angle of pneumatic turbine which are influencing the performance were carried out. The better matching schemes were gotten by regression analysis. The single factor experiments showed that the blade chord height affects the performance heavily and the nozzle angle influences the most. And the experiments proved U-D Design is a good way for multi level experiments.
