Abstract
The utility model discloses a submersible linear motor inner tube which is connected by the sections of dissimilar metals, and the inner tube is a circular cylinder body which is formed by the welding of alternate metal sections of a magnetic inductive metal (1) and a non-magnetic inductive metal (2). The utility model adopts the alternate metal sections of the magnetic inductive metal and the non-magnetic inductive metal to be welded together, so as to form the cylindrical linear motor inner tube, the utility model can shorten the electromagnetic coupling distance between a stator and a rotor to the maximum degree, thus the linear motor inner tube can not only support a winding electromagnetic system, but can also play the function of isolating well liquid without increasing the electromagnetic coupling distance between the stator and the rotor of the linear motor, furthermore, the utility model can also increase the pushing force of the linear motor and ensure the maximum pushing force of the linear motor under the same weight.
Description
One, technical field
The utility model relates to pipe in the oil immersion line motor.
Two, background technology
What pipe and shell were formed in the animal economy of oil immersion line motor was served as reasons is columnar structured, and the effect of interior pipe has two kinds, and the one, the winding electric magnetic system of support linear electric motors, the 2nd, barrier wells liquid can not contact well liquid with the winding of linear electric motors.At present, the interior pipe of the oil immersion line motor that uses in the real work is whole to be non-magnetic conductive metal, the wall thickness of the interior pipe of this non-magnetic conductive metal, interior pipe is in the winding electric magnetic system that supports linear electric motors, also increased the electromagnetic coupled distance between linear motor stator electric and the mover, reduce the thrust of linear electric motors, caused the thrust of oil immersion line motor to descend, influenced the operating efficiency of oil immersion line motor.
Three, summary of the invention
The purpose of this utility model is to manage in the oil immersion line motor that provides a kind of dissimilar metal segmentation to connect at the problems referred to above, shorten the electromagnetic coupled distance between stator and the mover to greatest extent, shorten the electromagnetic coupled distance between linear motor stator electric and the mover, increase the thrust of linear electric motors.
The utility model is to be achieved by following technical proposals: pipe in the oil immersion line motor that the dissimilar metal segmentation connects, interior pipe is that magnetic conductive metal and the alternate metal welding of non-magnetic conductive metal segmentation are connected into a circular cylinder body.
The good effect that the utlity model has: the utility model adopts magnetic conductive metal to be in the same place with the alternate metal solder of non-magnetic conductive metal segmentation, form pipe in the columnar linear electric motors, shortened the electromagnetic coupled distance between stator and the mover to greatest extent, make the interior pipe of linear electric motors not only play the effect of supporting the winding electric magnetic system but also playing barrier wells liquid, also do not increase the electromagnetic coupled distance between linear motor stator electric and the mover, increase the thrust of linear electric motors, guaranteed linear electric motors thrust maximum under equal quality.
Four, description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure: 1 magnetic conductive metal, 2 non-magnetic conductive metals
Five, embodiment
Fig. 1 is a structural representation of the present utility model, and as shown in the figure, interior pipe is that magnetic conductive metal 1 and the alternate metal welding of non-magnetic conductive metal 2 segmentations are connected into a circular cylinder body.The section of magnetic conductive metal 1 is wide between 5-20mm, and the section of non-magnetic conductive metal 2 is wide between 2-10mm.Magnetic conductive metal 1 specifically is meant the 45# steel to pure iron, and non-magnetic conductive metal 2 can not be magnetized, metal that can not magnetic conduction, as 301#, 304#, Monel stainless steel etc.During concrete the making, magnetic conductive metal 1 and the alternate placement of non-magnetic conductive metal 2 segmentations, the junction metal solder of magnetic conductive metal 1 and non-magnetic conductive metal 2 is made the circular cylinder body of required size.
