Abstract
A submersible linear motor closed permanent magnet structure includes permanent magnetic rings and magnetic inductive rings, the utility model is characterized in that: each permanent magnetic ring is arranged between two adjacent magnetic inductive rings, the peripheries of the permanent magnetic rings are embedded in non-magnetic inductive metal rings, the outer surfaces of the non-magnetic inductive metal rings and the outer surfaces of the magnetic inductive rings are melt-coated with a layer of wear-resistant and corrosion-resistant alloy layer, and non-magnetic inductive metal materials are used for fusion welding and sealing between the permanent magnetic rings and the magnetic inductive rings. The utility model has the advantages that the permanent magnetic rings are arranged in the closed environment, which can improve the corrosion resistance of the permanent magnetic rings of the linear motor; the alloy layer on the outer surfaces can improve the wear-resistant performance of the permanent magnetic rings of the linear motor, thus prolonging the service life of the linear motor.
Description
Technical field
The utility model belongs to a kind of linear electric motors parts that slip under the producing well, the closed magnet structure of particularly a kind of oil immersion line motor.
Background technology
The applicant has developed a kind of " reciprocating submersible electric pump " in the recent period, changed the artificial lifting way that recovers the oil, it has simple in structure, energy-saving and cost-reducing, easy to operate, advantages such as online accent ginseng, thoroughly solved the difficult problem of the side-abrasion of rod string of long-term puzzlement producing well, it not only can substitute trip Beam formula oil production equipment, be particularly useful for horizontal well, the oil recovery of clump formula oil well and stripper well, but at the scene in the use, the permanent magnet that discovery is located in the linear motor rotor is anti-corrosion, anti-wear performance is poor, usually cause linear motor performance to descend with corrosion because of it is damaged, thereby the useful life of having reduced linear electric motors.Seriously can not use in corrosion with containing in the husky oil well environment.
The utility model content
The purpose of this utility model provides the closed magnet structure of a kind of oil immersion line motor, improves anti-corrosion, the anti-wear performance of line motor permanent magnet, prolongs the useful life of linear electric motors.
The purpose of this utility model is achieved by the following technical solution: it comprises permanent-magnetic clamp and magnetic guiding loop in the mover, it is characterized in that: each permanent-magnetic clamp all is arranged between adjacent two magnetic guiding loops, in the non-magnetic conductive metal ring of permanent-magnetic clamp periphery insert, the alloy-layer of non-magnetic conductive metal ring outer surface and the equal cladding one deck of magnetic guiding loop outer surface wear-and corrosion-resistant adopts non-magnetic conductive metal material melting welding sealing between permanent-magnetic clamp and the magnetic guiding loop.
The utility model has the advantages that: permanent-magnetic clamp is arranged in the environment of sealing, has improved the corrosion resistance of linear electric motors permanent-magnetic clamps, and the outer surface alloy-layer has improved the anti-wear performance of linear electric motors permanent-magnetic clamps, thereby has prolonged the useful life of linear electric motors.
