英威騰GOODRIVE300系列變頻器在地面直驅螺桿泵抽油機上的應用

摘要：地面直驅式螺桿泵是在螺桿泵基礎上發展而成的抽油機械，采用永磁同步電機帶動光桿直接驅動井下螺桿泵，減少了機械減速器和皮帶減速器，效率很高。本文介紹了英威騰GOODRIVE300開環矢量型變頻器在地面直驅螺桿泵上的應用，其控制性能可靠，節能效率高。本文僅以37kW的GOODRIVE300變頻器為例進行分析，并為地面直驅式螺桿泵的節能改造提供應用方案。 敘詞：變頻器 地面直驅螺桿泵 英威騰 Abstract：Ground direct drive screw pump is an oil pump unit developed from screw pump, driven by permanent magnet synchronous motor direct drive downhole rod pumps, reducing the mechanical reduction gear reducer and belt, with high efficiency. This paper introduces application of INVT GOODRIVE 300 inverter in the ground direct drive screw pump, the control performance is reliable, energy-saving is efficiency. The analysis of this paper based on an example of 37kW GOODRIVE 300 inverter, and gives out application solutions for energy-saving of ground direct drive screw pumps.
