Abstract
The utility model relates to a magnetic steel and particularly relates to a neodymium iron boron magnetic steel for an oil field motor. The neodymium iron boron magnetic steel comprises a magnetic steel body, wherein an upper portion of the magnetic steel body is an upper arc end face, a lower portion of the magnetic steel body is a lower arc end face, the radian of the lower arc end face is greater than the radian of the upper arc end face, the magnetic steel body is provided with a displacement emission sensor, the material of the magnetic steel body is neodymium iron boron magnetic steel, and a surface of the magnetic steel body is coated with a nickel-coating layer. The neodymium iron boron magnetic steel for the oil field motor has a compact structure, improves product performance and prolongs service life.
Description
Technical field
The utility model is a kind of magnet steel, particularly a kind of Nd-Fe-B magnet steel for oil field motor.
Background technology
Magnet steel of the prior art, complex structure, and also fixed form is insecure, and result of use is not good, causes reduce its useful life.
Chinese patent 201020150678.5, discloses a kind of magnet, particularly a kind of samarium cobalt magnet with cambered surface that is mainly used in microwave communication technology, audio-visual technology, electrical engineering etc.Comprise magnet, described magnet pack is drawn together contour body and square body, and described contour body and square body are integrated, in described magnet, are provided with intermediate layer, and intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, compact conformation, and lifting assembly precision greatly promotes the Nd-Fe-B magnet steel for oil field motor of serviceability simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of Nd-Fe-B magnet steel for oil field motor, comprise magnet steel, the top of described magnet steel is provided with arc end face, the bottom of described magnet steel is provided with lower arc end face, the radian of described lower arc end face is greater than the radian of arc end face, in described magnet steel, be provided with displacement emission sensor, the material of described magnet steel is Nd-Fe-B magnet steel, and the surface of described magnet steel is covered with nickel coating.
Displacement emission sensor: when the displacement occurring in motor when magnet steel exceedes, displacement emission sensor is sent signal to control centre.
As preferably, the radius of described upper arc end face is 105.95～106.05mm, and the radius of described lower arc end face is 48.4～48.6mm, and the radian of described magnet steel is 23.9～24.1mm
As preferably, the two side ends of described magnet steel is respectively inclined plane.
Therefore, the Nd-Fe-B magnet steel for oil field motor that the utility model provides, compact conformation, improving product performance, increases the service life.
