Abstract
The motor of electric submersible screw pump comprises a stator, a rotator, a motor shaft, a rotator iron core and shaft, a thrust bearing, and an alignment bearing, wherein the stator punching has an outer diameter less than 190 mm and 24 holes, and the rotator punching has 22 holes matching the stator. The utility model can improve service life and reduce manufacture difficulty and cost of speed reducer, improve exploitation efficiency above 50%, solve problems caused by centrifugal pump and save energy. Compared with existing submersible motors, the motor component is versatile, thereby reducing the cost of product development and device investment and achieving wide application.
Description
(1) technical field:
The utility model relates to a kind of submersible electric machine with oil, particularly a kind of electric submersible screw pump motor.
(2) background technology:
At present, development and use along with oil-field thick-oil, its synchronous speed of prime mover 3000r/min that is used for the winning apparatus in heavy oil wells oil field is the two poles of the earth submersible electric machine with oils, because of the high investment cost that has increased miscellaneous equipments such as decelerator of prime mover rotating speed, also is a kind of waste from the energy.
(3) summary of the invention:
The purpose of this utility model is to design a kind of electric submersible screw pump motor, and it is overcome above-mentioned shortcoming, is a kind of practical novel electric submersible screw pump motor.
The technical solution of the utility model: a kind of electric submersible screw pump motor, comprise rotor that stator, rotor punching and the rotor core be made up of stator punching and stator winding form, machine shaft, and rotating shaft, thrust bearing and alignment bearing form the motor main body, it is characterized in that stator winding end U, V, W prime minister's winding are in lower floor, the tail phase winding is on the upper strata, contactless in the middle of its whole phase winding, the stator punching external diameter is below 190mm, stator punching groove number is no less than 18 holes, and the groove number and the stator of rotor are complementary.
Above-mentioned said stator punching groove number can be 24 holes, and the groove number of rotor punching can match with stator for 22 holes.
Above-mentioned said stator punching flute profile is trapezoidal; The rotor core sliver is special-shaped sliver.
The using method of the present utility model and the course of work are: stator winding adopts the wrapped copper cash coiling of polyimides-fluorine F46 laminated film, U, V, W prime minister's winding are pressed in lower floor in the end, the tail phase winding is on the upper strata, contactless phase-splitting layout that rolls off the production line in the middle of its whole phase winding, below external diameter 190mm, the groove number is the stator punching in 24 holes, the groove number is that the rotor punching in 22 holes matches, optimal design rotor teeth groove and yoke portion size, the rotor core sliver is special-shaped sliver, constitutes the electric submersible screw pump motor.
Superiority of the present utility model is: 1, this electric submersible screw pump motor, its synchronous speed 1500r/min, it and decelerator are supporting, can make and select the most important parameter of decelerator for use---gear ratio with select for use bipolar machine to compare to reduce one times, thereby improved the useful life of decelerator, and reduced the manufacture difficulty and the manufacturing cost of decelerator, make the unit production efficiency can reach more than 50%; 2, improve the adverse consequences of using centrifugal pump heavy crude producing well to bring significantly, thereby saved the valuable energy.3, this electric submersible screw pump motor, identical with existing submersible electric machine with oil (2 utmost point) part parts, highly versatile, the exploitation and the frock investment cost of having saved a large amount of new products; 4, market prospects are wide.
(4) description of drawings:
Accompanying drawing 2 is that the groove of rotor cooperates number, and rotor punching flute profile figure.
Wherein: 1 is stator punching, and 2 is rotor punching.
(5) embodiment:
Embodiment: a kind of electric submersible screw pump motor (seeing Fig. 1-2), comprise rotor that stator, rotor punching 2 and the rotor core be made up of stator punching 1 and stator winding form, machine shaft, and rotating shaft, thrust bearing and alignment bearing form the motor main body, it is characterized in that stator winding end U, V, W prime minister's winding are in lower floor, the tail phase winding is on the upper strata, contactless in the middle of its whole phase winding, the stator punching external diameter is below 190mm, stator punching 1 groove number is 24 holes, the groove number of rotor punching 2 is 22 holes, matches with stator.
Above-mentioned said stator punching 1 flute profile is trapezoidal; The rotor core sliver is special-shaped sliver.
