Problems solved by technology

However, when the stator is installed vertically and the mover moves up and down on both sides of the two-sided stator, due to the comprehensive influence of the load, magnetic force, suspension and guiding device, the gap between the two sides cannot be kept consistent for a long time, which greatly affects the performance of the linear moto

Abstract

The invention provides a beam-free linear electric-machine oil pump, having characters of stable structure, smooth working, high-efficiency energy saving and convenient use and maintenance, applied to oil pumping work in oil field and oil well. Its technical project: it includes main frame, stator fixed on the main frame, rope and rotor linked with the rope, as well as rotor guide rail, rotor guide wheel and spacing commutator, and its character: the stator is a unilateral structure and the rotor adapts to the stator. The rotor is fixed with balance weight box, there is a wind circulating cooling device in the cavity of the rotor, the spacing commutator can movably position, the top end of the main frame is set with head sheave and the main frame can move with the moving base.

Description

technical field [0001] The invention relates to oil production equipment, in particular to a beamless linear motor pumping unit. Background technique [0002] At present, in the oil field exploitation industry, the pumping equipment at the well head of an oil well is mainly a four-bar linkage beam pumping unit. This pumping unit is driven by a rotary motor, has complex structure, high energy consumption, low system efficiency, and it is very troublesome to adjust the stroke and stroke times. In view of this situation, beamless pumping units driven by linear motors have gradually become a hot spot for engineering and technical personnel to research and develop to meet the needs of modern oilfield mining. However, the oil well pumping unit is a large-scale equipment, the working environment and working conditions are relatively special, the development is relatively difficult, and the truly formed products are rare. Judging from some public technical materials and solutions,...
