并对两种机型提出了曲柄平衡位置工作实用图表,可供前置式抽油机设计和使用者参考。
Practical working charts for the crank balanced position of two types of units, which will give a reference to the designers and operators, are offered.
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。
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.
作者还认为,常规式抽油机的曲柄旋转方向应规定为逆时针,并建议研制可调相位角的曲柄平衡重。
The author holds further that the crank pin rotation on conventional pumping units should be assigned in counterclockwise...
