目前各油田的抽油设备为常规游梁式抽油机,其存在的主要问题是能耗大、效率低。而直线电机抽油机采用直线电机驱动,将传统的旋转驱动变为直线往复驱动。本文通过对直线电机抽油机的结构和工作原理做了大量的调研,并与常规游梁式抽油机做了对比,可知研究设计这种抽油机有着特殊的意义。 At present, the oil pumping equipment in each oil field is a conventional beam pumping unit, and the main problems that exist are energy consumption and low efficiency. The linear motor pumping unit uses a linear motor drive, the traditional rotary drive into a linear reciprocating drive. In this paper, through a lot of research on the structure and working principle of the linear motor pumping unit, compared with the conventional beam pumping unit, it is of special significance to study and design this kind of pumping unit.
