摘要
在石油开采过程中 ,原油粘度会随着时间的变化而变化 ,为提高抽油效率 ,必须调整抽油机的冲次。电磁离合器天然气机组可直接利用天然气资源 ,通过调整机组输入电流的大小来调整机组的输出转速 ,从而调节抽油机的冲次。
Oil viscosity will vary with time during oil production. It is necessary to adjust pumping speed of the pumping unit so as to improve oil recovery efficiency. The natural gas generating set with the electromagnetic clutch adopts natural gas directly and its output speed can be adjusted by changing its input current resulting in pumping speed of the pumping unit. This paper introduces the main structure and working principle of the natural gas generating set with electromagnetic clutch.
