仪金输油管道近几年来输量远低于设计输量,导致仪金输油泵机组在低负荷下长期节流运行,输油泵机组轴承和密封件损坏频次高,电耗高,影响仪金线的安全与经济运行。通过永磁调速器在仪金输油管道的节能改造,对比分析了改造后节能价值,保证仪金输油泵在低负荷下的安全运行,延长轴承和密封件的寿命,节电效果显著。 Yijin oil pipeline in recent years, the output is much lower than the design output, resulting in long-term low-cost MiGN oil pump unit running, oil pump unit bearings and seals high frequency damage, high power consumption, affecting the instrument line Safe and economical operation. Through the energy-saving transformation of permanent magnetic governor in YIJIN oil pipeline, comparatively analyzed the energy-saving value after the reform, ensured the safe operation of YINJIN oil pump under low load, prolonged the service life of bearings and seals, and achieved remarkable energy-saving effect.
