Description
Technical field
The invention belongs to oil production equipment mechanical manufacturing fields, are related to a kind of stator knot of oil-submersible linear lifting power device
Structure.
Background technique
According to investigations, current beam pumping unit walking beam product is big, and low efficiency, power consumption is big, waste of energy；For example, common
Rule formula oil pumping machine equipment physique has 15 tons of weights, 100 ㎡ of occupied area or so, and a large amount of idle operation is formd in working cycles,
A large amount of power consumptions are caused to waste, system effectiveness only 24%.In addition, Cut of Oilfield is up to 89%, since domestic underground energy declines
It develops oil fields whole into the ultra-high water-containing stage；Meanwhile being limited to traditional pumping unit sucker-rod pumping characteristic, structure is complicated, well casing
Bar eccentric wear is solved without good method, is worn according to domestic the reported single port oil well single in certain oil field, is replaced well casing bar and maintenance cost up to 3
As many as ten thousand yuan, in the nearly reserves newly developed of another aspect, hypotonic, Oil in Super-low Permeability, fine and close oil, particular lithologic ratio carries out up to 80%
Inclined shaft, horizontal well and big well indulge layout, and these exactly limit the use that existing tradition just has equipment.
Moreover, because traditional equipment birth defect in structure, can not realize good sealing in well head, there are also Hong Fanqu
Water submerged will certainly generate a large amount of landing oil, to bring adverse effect, especially " new two method " to promulgate on ground and the water surface
Since, the leakage accident of traditional equipment frequently occurs not being able to satisfy existing laws and regulations requirement.
Based on the above issues, although country's reciprocating submersible motor technology, part solve the oil recovery of hyposmosis small displacement at present
Problem, but it is also unresolved to low jig frequency, high thrust and huge discharge；It even is not met by current underground working requirement, periodically

By using new-type stator structure internal Structure of mover is moved, is promoted so that low-speed high-thrust dynamical system is realized
The effect of thrust.
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of oil-submersible linear lifting power device
Stator structure, which is characterized in that the stator includes tubular casing pipe, and to be axially fixed in nude inside casing pipe fixed
Son；Nude stator both ends and casing pipe both ends seal, so that nude stator and casing pipe contact position form seal chamber, it is described
Nude stator is made of multiple end to end non-packed stators.
A further technical solution lies in end is arranged in the two neighboring non-packed stator grafting, each non-packed stator one end
End plate two is arranged in disk one, the other end；The interface that the end plate one and two mutual of end plate are mutually adapted；Two neighboring described naked
When setting son by two grafting of end plate one and end plate, sliding bearing sleeve is set inside plug division；The internal diameter of the sliding bearing sleeve
It is consistent with nude diameter of stator bore；Sealing ring is set on the outside of its plug division；Seal chamber is divided into small seal chamber by the sealing ring.
A further technical solution lies in fill that high temperature resistant, high-insulativity, thermal conductivity be good, resistance to height in the seal chamber
Pressure, erosion resisting insulation glue.
A further technical solution lies in the insulating cement is fire resistant resin.
A further technical solution lies in the non-packed stator includes non-magnetic core cylinder, and is laminated on not by certain pole span
Several cupuliform silicon steel coils on magnetic conduction core cylinder；The cupuliform silicon steel coil includes cupuliform silicon steel sheet and coil, by cupuliform silicon
Steel disc punching press or wound around coil forms after being welded as a whole.
The beneficial effects of adopting the technical scheme are that the present invention is integrally formed folded cupuliform silicon steel made of falling
For coil under the action of electromagnetic field, magnetic line of force conduction is more smooth, and being vortexed in efficient conductive process reduces, temperature rise decline, insulation
Property improve, sealing performance improve.
More wear-resisting, corrosion-resistant using nonmetallic sliding bearing sleeve, force oscillation reduces, and mover movement is steady.Use sealing
Technique solves insulating oil rotten denaturing problem in long-term high temperature work, and breakthrough to solve Insulation Problems, effect obviously mentions
It is high.
