Description
Technical field:
The present invention relates to used a kind of oil recovery lifting device on the oil field, especially relate to a kind of motor that direct actuating force is provided for screw pump.
Background technology:
Employed power motor is common threephase asynchronous in the screw pump transmission device of oil field at present, and the belt pulley on the motor output shaft drives decelerator work by belt transmission, and reducer output shaft drives the rotation of screw pump sucker rod, realizes lifting crude oil.There are the following problems in running under this pattern: the one, and common threephase asynchronous must come transferring power by belt, decelerator, has increased by about 20% energy consumption; The 2nd, accessories such as decelerator, belt are fragile in daily production management, and the maintenance cost that is produced is higher; The 3rd, there is potential safety hazard in the ground drive apparatus when the screw pump rotating speed is higher.
Summary of the invention:
Have in the conventional threephase motor transmission process of the existing screw pump utilization in oil field in order to solve that energy consumption is big, the flimsy problems of accessory such as decelerator and belt, the invention provides a kind of directly-driven screw pump novel motor, with the contrast of former type of drive on the one hand electric energy loss descend approximately 20%, the regular maintenance expense reduces simultaneously; On the other hand high-speed rotary motor is changed into the low speed rotation motor, improved the coefficient of safety of wellhead equipment operation.
Technical scheme of the present invention is: this kind directly-driven screw pump hollow shaft motor, be with the basis of the matching used conventional motor of screw pump on the improvement made, constant part is motor field frame, motor upper end cover, motor upper end cover alignment bearing.Making the change part is: be embedded with an axial carrying cone bearing at the motor bottom end cover, and motor rotation axis is changed into hollow, have connection steel key groove in this upper end, a hollow seal pipe is arranged in this axle, be fixed with a cover mechanically-sealing apparatus between hollow seal pipe and the motor rotation axis, be called mechanically-sealing apparatus price fixing and mechanically-sealing apparatus Moving plate, fastening between mechanically-sealing apparatus price fixing and the hollow seal pipe by jackscrew, by rubber sealing, mechanically-sealing apparatus price fixing and mechanically-sealing apparatus Moving plate form working face between mechanically-sealing apparatus Moving plate and the motor rotation axis; Be fixed with a sealed tube alignment bearing outside the hollow seal pipe and between the inwall of motor rotation axis, have connecting thread in the bottom of hollow seal pipe, and be linked with stationary gland.
The present invention has following beneficial effect: because after taking such scheme, this novel motor can be vertically mounted on the screw pump well head ring flange, screw pump sucker rod and well mouth sealing device are installed in the hollow shaft of motor, therefore the direct transferring power of motor no longer needs decelerator, belt etc.Descend approximately 20% so compare on the one hand electric energy loss with former type of drive, the regular maintenance expense reduces, on the other hand, because directly drive screw pump sucker rod rotation of motor has improved the coefficient of safety that wellhead equipment moves.
Description of drawings:
Accompanying drawing 1 is a structure cut-away view of the present invention.
1-connects steel key groove, 2-mechanically-sealing apparatus price fixing, 3-motor upper end cover alignment bearing among the figure, 4-motor upper end cover, 5-mechanically-sealing apparatus Moving plate, 6-sealed tube alignment bearing, the 7-motor rotation axis, the 8-motor field frame, 9-hollow seal pipe, 10-axial carrying cone bearing, 11-motor bottom end cover, 12-motor bottom end cover alignment bearing, 13-ring flange connecting bolt hole, 14-stationary gland.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, this kind directly-driven screw pump hollow shaft motor is the improvement of making on the basis of conventional screw pump motor structure.The part that keeps original structure specifically is motor field frame 8, motor upper end cover 4, motor upper end cover alignment bearing 3, motor bottom end cover 11, motor bottom end cover alignment bearing 12 and motor stator and rotor portion.The part that makes improvements is: be embedded with an axial carrying cone bearing 10 at motor bottom end cover 11, become motor rotation axis 7 hollow, axial loads such as screw pump sucker rod, fluid column act on this axial carrying cone bearing 10 by motor-hollow axle like this, thereby realize the distribution of axial force.Have connection steel key groove 1 in this upper end, a hollow seal pipe 9 is installed in this axle, be fixed with a cover mechanically-sealing apparatus between hollow seal pipe 9 and the motor rotation axis 7, be called mechanically-sealing apparatus price fixing 2 and mechanically-sealing apparatus Moving plate 5, fastening between mechanically-sealing apparatus price fixing 2 and the hollow seal pipe 9 by jackscrew, pass through rubber sealing between mechanically-sealing apparatus Moving plate 5 and the motor rotation axis 7, mechanically-sealing apparatus price fixing 2 and mechanically-sealing apparatus Moving plate 5 form working face, can bear the fluid pressure of 1～2Mpa.Be fixed with a sealed tube alignment bearing 6 outside hollow seal pipe 9 and between the inwall of motor rotation axis 7, guarantee hollow seal pipe 9 centerings, guarantee sealing effectiveness.The bottom is linked with stationary gland 14, and both realize the function that supports and set upright jointly.Bottom at hollow seal pipe 9 has connecting thread, and purpose is to be connected with the screw bolt well well head.
During use, this novel directly-driven screw pump is vertically mounted on the screw bolt well well head four-way ring flange with hollow shaft motor, the screw pump sucker rod passes hollow motor rotation axis 7, connects motor rotation axis at the motor reel output by the moment of torsion clamp.Motor driver control directly-driven screw pump turns round with hollow shaft motor during work, the full well sucker rod of screw pump roofbolt weight and fluid column weight act on the axial carrying cone bearing 10 of motor internal, upper end cover alignment bearing 3, bottom end cover alignment bearing 4 guarantee outside the motor normal operation function, also play radially centralizing function, motor rotation axis 7 directly drives the work of screw pump sucker rod by the moment of torsion clamp.
The specific implementation of this programme can make improvements on the basis of three-phase AC asynchronous motor, also can make improvements on the basis of triphase AC synchronous permanent-magnet motor machine.
