Description
One, technical field
The utility model relates to the relative oil-immersed pump motor that rubs of no metal that a kind of oil field electric immersible pump well is used.
Two, background technology
Movement parts in the oil-immersed pump motor all adopts alloy components and tin bronze or the babbit friction pair that partners for many years, radially centralizing system is that the alignment bearing outer ring of GCr15 alloy and the silicon copper sheet in the stator core have relative motion, the alignment bearing outer ring of alloy and the alignment bearing inner ring of the tin bronze friction pair that partners, the thrust system is the thrust motion block of GCr15 and the quiet friction pair that partners of babbit or tin bronze.In the submersible electric machine with oil course of work, this several to friction pair under high speed rotating, have under a large amount of copper powders or the babbit grinding, glittering in the dynamo oil that makes, influenced the good lubricating oil performance of lubricating oil, and be that the electrical insulation properties of lubricating oil reduces greatly, for many years, he is a big problem that influences electrical machinery life and efficient always.
Three, summary of the invention
The purpose of this utility model provides a kind of metal oil-immersed pump motor of friction relatively that do not have, and overcomes the shortcoming that above-described oil-immersed pump motor exists.
The technical solution of the utility model realizes in the following manner:
No metal is the oil-immersed pump motor of friction relatively, by cylindrical housings, motor head on it, the motor base under it, stator in it and rotor are formed, it is characterized in that on motor head inwall round boss, being provided with cylindrical shaft to thrust terminator, between stator silicon steel pipe nipple, be provided with cylindrical PEEK composite material magnetic isolating segment, between the rotor pipe nipple on the motor shaft, be provided with the radially centralizer that cylindrical alloy cylinder and PEEK composite material cylinder are formed.
The axial thrust device is made up of PEEK composite material cylinder and GCrl15 alloy cylinder, and PEEK composite material cylinder is assemblied under the GCrl15 alloy cylinder.
PEEK composite material magnetic isolating segment is embedded in inwall and is provided with in the steel pipe of groove.
Radially centralizer is formed by overlapping in magnetic isolating segment cylinder, GCrl15 alloy cylinder overcoat and the PEEK composite material.Interior cover is connected on the motor shaft by dedicated array of keys, and overcoat is embedded between interior cover and the magnetic isolating segment, and is slidingly matched with it.PEEK composite material magnetic isolating segment is by cylindrical metal shell body and the composite material moulded shaping of PEEK.
Great advantage of the present utility model is that motor is following in working order, radially centralizing system alignment bearing outer ring and magnetic isolating segment do not have relative motion, it is all that the part of relative motion is arranged all is GCrl15 alloy components and the relative motion of PEEK composite material element, no galling, the cleannes and the electric property of dynamo oil have been improved, prolong the useful life of motor, and improved efficiency of motor.
