摘要
对抽油机的平衡问题作了细致的研究，指出配重平衡与气压平衡是抽油机的两种主要平衡方式，提出了采用弹簧平衡与飞轮平衡的可能性，说明了各种平衡方式的参数确定方法；指出提高抽油机效率的方法是提高电动机和传动机构的效率，并对后者作了分析与表示。此外还提出了抽油机用感应电动机容量选择的方法。
Counterbalance problem of oil pumping unit is researched in detail,and it is pointed out that counterbalances of matching weight and gas pressure are two main types of counterbalance of oil pumping unit.The possiblity for oil pumping unit to use spring counterbalance or flywheel counterbalance is put forward. The methods of ascertaining counterbalance parameters are indicated.It is indicated that the way for raising efficiency of oil pumping unit is increase the efficiency of induction motor and transmission mechanism.The latter is analyzed and expressed.Besides,the method of determining power demand of induction motor used for oil pumping unit is put forward.
