Abstract
The utility model discloses an oil submersible straight line motor, the end of the motor is welded fully through metal. The utility model comprises an inner pipe (1) and a crust (2). The circular space between the inner pipe (1) and the crust (2) is provided with a winding and an electromagnetic system (3) of the straight line motor, and the connection positions (5 and 6) of the motor head, the inner pipe (1) and the crust (2) of the straight line motor end are welded into an entirety through full metal. The utility model separately welds the motor head with the joint of the inner pipe and the crust at the end of the straight line motor with full metal, so that the motor head, the inner pipe and the crust are integrated into an entirety, the winding and the electromagnetic system of the straight line motor are completely sealed in the circular space of the inner pipe and crust, thereby effectively preventing the well liquid from entering into the circular space of the inner pipe and the shell to damage the motor, and thoroughly solving the sealing problem of the straight line motor.
Description
One, technical field
The oil immersion line motor that the utility model relates to specifically is the oil immersion line motor of a kind of end all-metal sealing.
Two, background technology
Oil immersion line motor is because the needs of applied environment all are columnar, form by interior pipe and shell, annular space between interior pipe and the shell is the winding and the electromagnetic system of linear electric motors, is screwed connection between the motor head at linear electric motors two ends and interior pipe, the shell, and seal is " O " type circle.Because oil immersion line motor is in well liquid and is long-term operation in the running environment of high temperature and vibrations that the service conditions of high temperature, vibrations makes that screw thread is loosening easily, " O " type circle damages, well liquid infiltrates and damages motor.Therefore the oil immersion line motor both ends both the sealing effectiveness between the motor head at linear electric motors two ends and interior pipe, the shell directly influence the useful life and the production safety of oil immersion line motor.
Three, summary of the invention
The purpose of this utility model is the oil immersion line motor that a kind of end all-metal sealing is provided at the problems referred to above, prevents that effectively well liquid from mixing the annular space damage motor of interior pipe and shell.
The utility model is to be achieved by following technical proposals: the oil immersion line motor of a kind of end all-metal sealing is made of interior pipe, shell, the winding and the electromagnetic system of linear electric motors are housed in the annular space of interior pipe and shell, and the motor head of linear electric motors end makes the motor head of linear electric motors end become as a whole with interior pipe, shell with the junction all-metal welding of interior pipe, shell.
The good effect that the utlity model has: the utility model is adopting the all-metal welding with the junction of interior pipe, shell in the end of linear electric motors respectively with the motor head, make the motor head become as a whole with interior pipe, shell, prevented that effectively well liquid from mixing the annular space damage motor of interior pipe and shell, thoroughly solved the sealing problem of linear electric motors.
Four, description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure: pipe 2 shells, 3 windings and the junction 6 motor heads of electromagnetic system 4 motor heads, 5 motor heads and interior pipe and the junction of shell in 1
Five, embodiment
Fig. 1 is an overall structure schematic diagram of the present utility model, according to shown in Figure 1, the oil immersion line motor of a kind of end all-metal sealing is made of interior pipe 1, shell 2, the winding and the electromagnetic system 3 of linear electric motors are housed in the annular space of interior pipe 1 and shell 2, the motor head 4 at linear electric motors both ends and the junction 5 of interior pipe and motor head 4 and the junction 6 of shell adopt the all-metals welding to make motor head 4 and interior pipe 1,2 one-tenths on shell as a whole, the winding that makes linear electric motors and electromagnetic system 3 be completely enclosed within interior manage 1 and the annular space of shell 2 in.
Claims (1)
