Technical field
What the utility model related to that a kind of well uses be arranged in water and the supporting filling type submersible asynchronous motor of well immersible pump, particularly a kind of oil-filled type well submersible asynchronous motor.
Background technology
At present, the well of domestic production is roughly divided into dry type, filling type and three kinds of forms of Water with submersible motor, conventional dry, filling type motor exist seal complex and reliability not high in the prior art, and especially the static seal place of motor causes burn-down of electric motor owing to more easily intake by the effect of motor inside and outside differential pressure; The shortcoming of wet motor is that stator and rotor directly contact with water, very easily corrosion, and useful life is not long, and bearing is quite expensive.Due to submersible motor complex structure, assembly technology difficulty is large, is difficult for realizing assembling automation, and overall performance is difficult for ensureing, develops process structure simple for this reason, and good reliability easily realizes the submersible electric motor of assembling automation, is current problem demanding prompt solution.
Summary of the invention
The utility model has overcome the defect of above-mentioned existence, and object is that to have solved motor sealing structure part unreliable, and assembly technology complexity, is difficult for realizing the problems such as automation, and a kind of oil-filled type well submersible asynchronous motor is provided.
The utility model oil-filled type well submersible asynchronous motor content Description:
The utility model oil-filled type well submersible asynchronous motor, formed by gland, pressure regulation capsule, motor cylinder, bottom end cover, stator, pin, upper end cover, " O " shape cushion rubber, oil filler point screw and rotor, it is characterized in that: stator and motor cylinder interference fit are arranged in motor cylinder, motor cylinder and pressure regulation capsule, gland form the static seal of motor lower end, coordinate by the internal projecting ring of motor cylinder lower end and the outer scrobicular ring of pressure regulation capsule, ensure the axial location of pressure regulation capsule; The interference fit of excircle and pressure regulation capsule endoporus by gland, makes pressure regulation capsule fixing seal, and pressure regulation capsule lower end thickness is grading structure, and motor cylinder is connected by pin with upper end cover, and the front end of pin is chamfering form; On upper end cover, be provided with the static seal at " O " shape cushion rubber and oil filler point screw composition oil filler point place.
The utility model oil-filled type well submersible asynchronous motor, the structural design of employing automatic Composition, by stator and motor cylinder interference fit, bottom end cover contacts with stator faces tightening seal, forms and ensured axial location and the axiality of stator; Pressure regulation capsule lower end Thickness Design is gradual change form, has improved the anti-fatigue ability of pressure regulation capsule, ensures the reliability of static seal.
Brief description of the drawings
Fig. 1 is oil-filled type well submersible asynchronous motor structural representation:
In figure: the 1st, gland, the 2nd, pressure regulation capsule, the 3rd, motor cylinder, the 4th, bottom end cover, the 5th, stator, the 6th, pin, the 7th, upper end cover, the 8th, " O " shape cushion rubber, the 9th, oil filler point screw, the 10th, rotor.
Embodiment
The utility model oil-filled type well is achieved in that below in conjunction with accompanying drawing and illustrates with submersible asynchronous motor.See Fig. 1, oil-filled type well submersible asynchronous motor, by: gland 1, pressure regulation capsule 2, motor cylinder 3, bottom end cover 4, stator 5, pin 6, upper end cover 7, " O " shape cushion rubber 8, oil filler point screw 9 and rotor 10 form, stator 5 is arranged in motor cylinder 3 with motor cylinder 3 interference fit, when assembling, on automatic Composition line, by pressure apparatus, stator 5 and bottom end cover 4 are pressed in motor cylinder 3 simultaneously, ensure the axial location of stator 5, ensure the dead eye of bottom end cover 4 and stator 5 endoporus, motor cylinder 3 upper end endoporus axialities simultaneously.
Motor cylinder 3 and pressure regulation capsule 2, the gland 1 of submersible motor forms the static seal of motor lower end, coordinates by the internal projecting ring of motor cylinder 3 lower ends and the outer scrobicular ring of pressure regulation capsule 2, ensures the axial location size of pressure regulation capsule 2; The interference fit of excircle and pressure regulation capsule 2 endoporus by gland 1, makes pressure regulation capsule 2 fixing and realize sealing.Pressure regulation capsule 2 lower end Thickness Design are grading structure, have improved the anti-fatigue ability of pressure regulation capsule 2.Motor cylinder 3 is connected by pin 6 with upper end cover 7, and the front end of pin 6 is arranged to the chamfering form of certain angle, is convenient to the automatic assembling of pin 6.On upper end cover 7, be provided with " O " shape cushion rubber 8 and oil filler point screw 9, formed the static seal at oil filler point place by upper end cover 7, " O " shape cushion rubber 8, oil filler point screw 9, " O " shape aprons slot of oil filler point screw 9 and upper end cover 7 is arranged to special size shape, makes 8 compressions of " O " shape cushion rubber ensure the reliability of static seal.Oil filler point screw 9 upper ends are large chamfering form, are convenient to automatic assembling.
Advantage of the present utility model is as follows:
1, stator 5 and motor cylinder 3 interference fit, bottom end cover 4 contacts with stator faces tightening seal, makes automatic Composition become possibility.And ensure the axial location of stator 5, ensured hole axiality in the dead eye of bottom end cover 4 and 5 li of holes of stator, motor cylinder 3 upper ends simultaneously.
2, motor cylinder 3 and pressure regulation capsule 2, gland 1 have formed the static seal of motor lower end.Pressure regulation capsule lower end Thickness Design is grading structure, has improved the anti-fatigue ability of pressure regulation capsule 2.
