balance-type beam pumping unit 天平式游梁抽油机
The virtue of balance beam pumping unit is directly depended on its balanced state. But so far, there is no simple and efficient method to detect the balanced state.
游梁式抽油机的平衡状况直接关系到其效能，而对其平衡的检测目前尚无简单易行的办法。
In view that large top torque and negative torque are produced when crank balance (primary balance) is adopted, we present the secondary balance of beam pumping unit.
针对游梁式抽油机在采用曲柄平衡(又称一次平衡)时存在的峰值转矩较大、负转矩严重等现象，提出了有关抽油机的二次平衡问题。
For great workload well, the beam-pumping unit works out of balance generally. It not only wastes energy resources, but also shortens the service life of the pumping unit seriously.
常规游梁式抽油机普遍存在平衡不足的现象，既浪费能源，又严重影响抽油机的使用寿命。
