摘　　要：针对某型航空齿轮泵在极端温度环境下的工作特性测试需求,设计了一套液压泵高低温性能测试方案,并搭建测试试验台架,完成齿轮泵高低温性能测试。结果表明,被试泵的流量-压力特性满足技术指标要求,液压泵的容积效率与工作温度及加载压力成反比。According to working characteristics test of an aviation gear pump under extreme temperature environment,a high and low temperature performance test scheme of the hydraulic pump is designed.Then,the test bench is built,and the gear pump working performance is tested under diverse temperatures.The results show that the flow-pressure characteristic is accordant to the pump technical requirements,while the pump volumetric efficiency is inversely proportional to its temperature and loading pressure.
