| 摘 要： | 给出了测取液压抽油机系统压力损失、流量损失以及油缸的摩擦力损失等的方法。并由此求出系统的机械效率与容积效率。此外，还给出了电机—油泵组合体的效率测试方法及功率因数对效率的影响。从而测算出液压抽油机的地面效率，此法对一般的液压抽油机均适用。

| Abstract: | The test method of pressure loss,flow loss and frictional force loss etc.of the hydraulic pumping units is presented,from which the mechanical efficiency and volumetric efficiency are obtained.In addition,the test method of the efficiency of the combination of motor-oil cylinder and the effect of power factor on efficiency is proposed.Aftewards the surface efficiency of the hydraulic pumping units is measured and calculated.This method can be applied to the traditional hydraulic pumping units also. |
