△变频调速技术,是近年来国外研制成功的一项成熟的节能技术。它通过调节频率变动电机转速,使电机出力与所带机泵负荷匹配,防止大马拉小车浪费电力。我国已在大庆、辽河油田和东北长输管道上引用这项技术,取得显著节电效果。如辽河油田在脱水、掺油和给水三台泵上使用一年,节省一台脱水泵,共节电142×10~4kwh,折电费28.43万元,而这几台变频调速装置投资只有19.75万元。总公司于3月15日至17日辽河油田召开变频调速技术现场推广会,大庆、胜利、辽河、大港、
△ frequency control technology, developed in recent years abroad is a mature energy-saving technology. It adjusts the frequency by changing the motor speed, motor output and pump load to match, to prevent the big horse car wasting power. China has cited this technology in Daqing, Liaohe Oilfield and Northeast long-distance pipeline and achieved significant energy-saving effect. Such as Liaohe Oilfield dehydration, oil and water three pumps on the use of one year to save a dehydration pump, a total power saving 142 × 10 ~ 4kwh, 28,400 yuan of electricity charges, while the frequency of these devices investment is only 19.75 Million. Head office in March 15 to 17 Liaohe Oilfield held a frequency control technology site promotion, Daqing, victory, Liaohe, Dagang,
