游梁式抽油机的平衡与节能

作者利用抽油机等效动力学模型,对采用高转差率电机的抽油机的节能原理进行了研究,说明系统动能的均衡效果决定于系统等效转动惯量,也决定于电机转速的变化范围,同时指出,高转差率电机使抽油机的实际冲数降低。

Counterbalance and Energy Saving on Beam Pumping Units

By the aid of an equivalent kinetic model, the author makes a study of the principle of energysaving for beam pumping units driyen by highslip motors and asserts that the balance effect of system kinetic energy depends on the equivalent rotational inertia of the system and also on the variation range of the motor speed. The author points out additionally that the use of high-slip motor is liable to reduce the actual pumping speedof the unit.
