摘　　要：通过对深海油压动力源结构组成的分析,揭示了深海油压动力源功率的传递过程。首先,在深海油压动力源三个系列的地面试验中,采集了输入电压、电流以及输出的流量(调定压力下)等参数。然后,以深海油压动力源电机的测试数据为样本,通过数据拟合得到电机不同负载率下功率因数计算公式。最后,再结合泵的参数及试验采集数据进行计算,得到了深海油压动力源的容积效率曲线和总效率曲线。结果表明:低负载时,总效率低。而其主要原因为:低负载时电机的机械损耗与铁耗占电机输入功率的比例较大,导致电机效率偏低,继而影响整机的效率。This paper reveals the process of power transmission of deep-sea hydraulic power source by analysing its structure. Collected input parameters such as voltage, current, and output flow （set pressure） in the ground experiment of 3 series. By data fitting the test data of the motor, obtained PF＇ s formula under different load. Then, combined with the parameters of the pump and test data to calculate get the volumetric efficiency curve and efficiency curve. The results show that the total efficiency is low when the load is low. And the main reason is that low load motor＇ s mechanical and no-load core loss account larger proportion of the motor input power, so it push the motor efficiency down. And then affecting overall efficiency.
