Conclusions are drawn as follows : ( 1 ) regulating the electromotor speed by adjusting the input voltage is easy to carry out, and it can be used in most of the oil fields ; ( 2 ) good energy - saving effect can be achieved under the condition of light load on the motor ; ( 3 ) the voltage cannot be regulated in a large range, and the optimal range of the voltage regulation is less than 10 % of the rated voltage
由此得出結論: ( 1 )調電動機端電壓調速方法簡單,一次性投資少,易於實現,對於一般的油田都適用; ( 2 )調壓調速只有在輕負荷時,即在負荷遠未達到滿負荷時才有一定的節能效果,適用於油田普遍存在的「大馬拉小車」的情況; ( 3 )電動機調壓調速的范圍不能太大,電壓調整的最佳范圍為額定電壓的10 %以內。
