Abstract
A kind of self seal structure of oil-submersible linear electric motor permanent magnet, comprise annular permanent magnet, it is characterized in that the surface being set through magnetic conductive metal material layer wear-resisting, anti-corrosion processing at upper and lower two end faces of annular permanent magnet, the surface is set through non-magnetic conductive metal ring wear-resisting, anti-corrosion processing on the outer circumference surface of annular permanent magnet, anti-corrosion non-magnetic conductive metal ring is set on the periphery within it, and the non-magnetic conductive metal ring that is provided with on the magnetic conductive metal material layer of upper and lower two end face settings and the inside and outside periphery is by the melting welding sealed attachment.Advantage of the present invention is that annular permanent magnet is placed in the sealed environment, completely cut off multiple corrosive medium in the well liquid to its corrosiveness, avoid the inner and surperficial chemical change of permanent magnet, stablize the magnetic property of permanent magnet, anti-corrosion, the anti-wear performance of outer surface strengthen, and then improved the compressive resistance of permanent magnetic material, improved anti-corrosion, the anti-wear performance of oil immersion line motor mover, thereby improved the useful life of oil immersion line motor.
Description
Technical field
The invention belongs to a kind of assembly that is used on the oil immersion line motor mover, particularly a kind of oil-submersible linear electric motor permanent magnet sealing, self seal anticorrosion, wear-resisting, that strengthen are protected structure.
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.But put into practice by on-the-spot the use, permanent magnet in the discovery oil immersion line motor mover is anti-corrosion, anti-wear performance is poor, usually damaged and corrosion causes motor performance to descend because of it, has influenced the useful life of oil immersion line motor, particularly at seriously corroded with contain in the sand oil well environment and can not use.
Summary of the invention
The self seal structure that the purpose of this invention is to provide a kind of oil-submersible linear electric motor permanent magnet, avoid the inner and surperficial chemical change of permanent magnet, stablize the magnetic property of permanent magnet, improve the compression strength of permanent magnet fragile material, have higher hydraulic pressure resistant ability simultaneously.Improve anti-corrosion, the anti-wear performance of oil immersion line motor mover, thereby improve the useful life of oil immersion line motor.
The objective of the invention is to be achieved through the following technical solutions: comprise annular permanent magnet, it is characterized in that: upper and lower two end faces at annular permanent magnet are provided with the surface through magnetic conductive metal material layer wear-resisting, anti-corrosion processing, the surface is set through non-magnetic conductive metal ring wear-resisting, anti-corrosion processing on the outer circumference surface of annular permanent magnet, anti-corrosion non-magnetic conductive metal ring is set on the periphery within it, and the non-magnetic conductive metal ring that is provided with on the magnetic conductive metal material layer of upper and lower two end face settings and the inside and outside periphery is by the melting welding sealed attachment.
Advantage of the present invention is: annular permanent magnet is placed in the sealed environment, multiple corrosive mediums such as acid in the well liquid, alkali, hydrogen, oxygen have been completely cut off to its corrosiveness, avoid the inner and surperficial chemical change of permanent magnet, stablize the magnetic property of permanent magnet, anti-corrosion, the anti-wear performance of outer surface strengthen, and then improved the compression strength of permanent magnet fragile material, have higher hydraulic pressure resistant ability simultaneously.Improved anti-corrosion, the anti-wear performance of oil immersion line motor mover, thereby improved the useful life of oil immersion line motor.
Description of drawings
Fig. 1 is the schematic appearance of product of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is that product of the present invention is assembled in the schematic diagram on the oil immersion line motor mover.
Embodiment
Concrete technical scheme of the present invention is as follows: see Fig. 1,2, upper and lower two end faces at annular permanent magnet 4 are provided with magnetic conductive metal material layer 1, non-magnetic conductive metal ring 2 is set on the outer circumference surface of annular permanent magnet 4, anti-corrosion non-magnetic conductive metal ring 3 is set on the periphery within it, the non-magnetic conductive metal ring that is provided with on the magnetic conductive metal material layer 1 of upper and lower two end face settings and the inside and outside periphery 3,2 by the melting welding sealed attachment, is sealed annular permanent magnet 4 at its seam crossing.With wear-resisting, the anti-corrosion processing of non-magnetic conductive metal ring 2 surfaces that are provided with on magnetic conductive metal material layer 1 surface of two end face settings and the outer circumference surface through conventional process of surface treatment such as plating, surfacings, the anti-corrosion non-magnetic conductive metal ring 3 that is provided with on the inner peripheral surface is selected anti-corrosion metal material for use, as stainless steel.
See Fig. 3, a plurality of products of the present invention and a plurality of magnetic conductor 5 are assembled on the oil immersion line motor mover mandrel 6 separately, constitute mover assembly with self seal structure annular permanent magnet.
