由於油田注水泵的de實shi際ji流liu量liang比bi泵beng的de額e定ding流liu量liang小xiao，因yin此ci節jie電dian潛qian力li較jiao大da。係xi統tong中zhong注zhu水shui泵beng的de注zhu水shui控kong製zhi是shi由you變bian頻pin器qi通tong過guo變bian送song器qi的de回hui饋kui壓ya力li值zhi

；同時變頻器的運行參數通過內部計算機接口和通訊協議傳輸至計算機工作站；在計算機上可以隨時檢測和控製係統運行壓力
、電動機轉速、輸入/輸出電壓、輸入/輸出電流等參數
，達到係統自動節能運行的目的。
