Abstract
The utility model relates to an oil-submersible linear electric motor mover, which comprises a mover mandrel, closed annular permanent magnets and annular magnetizers, and is characterized in that the combination between each of the closed annular permanent magnets and each of the annular magnetizers is welded into a whole through laser. The mover has the advantages that the closed annular permanent magnets and the annular magnetizers are welded into a whole through the laser, which obviously improves the strength of a linear electric motor mover, reduces the bending deflection, and eliminates the problem of sweeping the cavity of the electric motor mover, thereby the mover prolongs the service life of the oil-submersible linear electric motor, and simultaneously is easy to realize technically.
Description
Technical field
The utility model belongs to a kind of assembly that is used on the oil immersion line motor, particularly a kind of oil immersion line motor mover.
Background technology
The general oil recovery machiner that is made of oil pumper, sucker rod and oil well pump that adopts at present both at home and abroad recovers the oil, there are shortcomings such as volume is big, cost is high, ineffective power consumption greatly, easily breaks down in existing oil recovery machiner, the applicant has developed a kind of " reciprocating submersible electric pump " for this reason, fundamentally changed the artificial lifting way of oil extraction, have characteristics such as accent ginseng simple in structure, energy-saving and cost-reducing, easy to operate, online, the sucker rod that has thoroughly solved long-term puzzlement mechanical oil recovery both at home and abroad takes off, the difficult problem of disconnected and side-abrasion of rod string.It not only can substitute trip Beam formula oil production equipment, also is highly suitable for the oil recovery of horizontal well, deviated directional drilling and hyposmosis oil well.The structure of its main core component oil immersion line motor mover: be on oil immersion line motor mover mandrel, to assemble a plurality of closed ring permanent magnets and a plurality of magnetic conductor separately.Use practice by the scene, find the linear motor rotor mandrel because axial dimension is oversize, and the generation amount of deflection that is in operation easily causes electric mover to sweep thorax, and motor is worn and torn, the life-span of oil immersion line motor is used in influence.
The utility model content
The purpose of this utility model provides a kind of oil immersion line motor mover, improves the intensity of linear motor rotor, reduces amount of deflection, gets rid of electric mover and sweeps the thorax problem, prolongs the useful life of oil immersion line motor.
The purpose of this utility model is achieved by the following technical solution: comprise mover mandrel, closed ring permanent magnet and annular magnetizer, it is characterized in that: the junction between each closed ring permanent magnet and each annular magnetizer becomes one by laser welding.
The utility model has the advantages that: closed ring permanent magnet and annular magnetizer are become one by laser welding, significantly improve the intensity of linear motor rotor, reduce amount of deflection, get rid of electric mover and sweep the thorax problem, thereby improve the useful life of oil immersion line motor, be easy on the technology simultaneously realize.
Description of drawings
Fig. 1 is the structural representation of the utility model product.
Embodiment
Concrete technical scheme of the present utility model is as follows: see Fig. 1, with a plurality of closed ring permanent magnets 3 and a plurality of annular magnetizers 1 (employing iron core), be assembled in separately on the oil immersion line motor mover mandrel 6, the junction between each closed ring permanent magnet 3 and each annular magnetizer 1 is welded into one by laser weld bond 2.Closed ring permanent magnet 3 is the outer setting protective layers 5 at annular permanent magnet 4; promptly at two end faces the surface is set and on the magnetic conductive metal material layer of wear-resisting, anti-corrosion processing and the periphery at annular permanent magnet the surface is set and constitutes through non-magnetic conductive metal ring wear-resisting, anti-corrosion processing, the non-magnetic conductive metal ring on the magnetic conductive metal material layer of two end faces and the periphery is by the melting welding sealed attachment.
Claims (1)
1, a kind of oil immersion line motor mover comprises mover mandrel, closed ring permanent magnet and annular magnetizer, it is characterized in that: the junction between each closed ring permanent magnet and each annular magnetizer becomes one by laser welding.
