摘　　要：为了研究高海拔环境对矿山机械设备效率的影响,设计了一套低压低氧矿用环境模拟试验舱,可模拟不同海拔高度的矿山大气环境,应用模拟试验舱,测试矿用电动隔膜泵在不同海拔条件下的性能,开展电动隔膜泵的流量、进出口压力、扭矩、转速和功率变化的试验研究。结果表明:电动隔膜泵在高海拔地区运行时,由于大气压力低导致扭矩和功率下降,当海拔为5000 m时,扭矩下降25.7%、功率下降25.6%;电机转速、流量受海拔的影响较小;进口压力随着海拔的升高变化相对明显,当海拔为5000 m时,进口压力下降79.2%。In order to study the influence of high altitude environment on the efficiency of mining machinery and equipment,a set of low pressure and low oxygen mining environment simulation experiment cabin was designed,which could simulate the mine atmospheric environment at different altitudes.The performance of mine electric diaphragm pump at different altitudes was tested by using the simulation experiment cabin,and the experimental study on the changes of flow,inlet and outlet pressure,torque,speed and power of electric diaphragm pump was carried out.The results show that when the electric diaphragm pump operates in high altitude area,due to the low atmospheric pressure,the torque and power decrease.When the altitude is 5000 m,the torque decreases by 25.7% and the power decreases by 25.6%.The motor speed and flow are less affected by altitude.The inlet pressure changes obviously with the increase of altitude,when the altitude is 5000m,the inlet pressure decreases by 79.2%.
