Abstract
The utility model provides a submerged electric pump for well, and belongs to the technical field of pumps. The submerged electric pump for well solves the technical problems of existing submerged electric pump that the sealing effect is bad, the service life is short, and the like. The submerged electric pump for well comprises a pump body and a shell of a motor, the pump body and the shell of the motor are connected into a whole, a stator and a rotor are arranged in the shell of the motor, a screening sleeve for sealing the stator and preventing water is arranged between the stator and shell, and epoxide resin is further filled between the screening sleeve and the stator. The submerged electric pump for well has the advantages of good sealing effect, long service life, strong using stability and the like.
Description
Technical field
The utility model belongs to the pump technical field, relates to a kind of Submerged Motor Pumps, particularly a kind of well Submerged Motor Pumps.
Background technique
Existing well mainly is made of motor and motor-driven pump housing two-part with Submerged Motor Pumps.Existing well can be divided into two kinds with Submerged Motor Pumps by structure.A kind of is the totally-enclosed well Submerged Motor Pumps of oil immersed type (or dry type), this kind well is with static seal abrading block of fixing with the motor stator shell and the motive sealing abrading block of fixing with the motor output shaft end with Submerged Motor Pumps on the motor output shaft end, surface of contact by dynamic and static sealing abrading block is realized the sealing of motor internal under dynamic state of run, guarantees that water does not enter in the motor; Because be in sealing state in the motor, its coil of stator of motor adopts common enameled wire loop.But because existing well all is to make with common iron with the output shaft of Submerged Motor Pumps, in water, soak for a long time and make its surface corrosion, cause the sealing between motor output shaft end and motive sealing abrading block to descend, even destroyed sealing therebetween fully, add the wearing and tearing that cause because of long-time running between the dynamic and static sealing abrading block, make the motor internal water inlet.This is the main cause that the totally-enclosed well of oil immersed type (or dry type) breaks down with Submerged Motor Pumps.The well Submerged Motor Pumps of another kind of structure is an immersion type well Submerged Motor Pumps.The well of this kind structure moves under non-hermetic environments with the motor of Submerged Motor Pumps, its stator coil adopts water resistence plastic covered wire circle, and coil is by water-cooled, but motor bearings soaks in water for a long time, damage easily, influence operational reliability and working life that well is used Submerged Motor Pumps.
The model utility content
The purpose of this utility model is to have above-mentioned problem at existing well with Submerged Motor Pumps, improves that a kind of sealing effect is better, the well Submerged Motor Pumps of longer service life.
The purpose of this utility model can realize by following technical proposal: a kind of well Submerged Motor Pumps, the housing that comprises the pump housing and motor, the housing of the pump housing and motor fuses, stator that in the housing of motor, is provided with and rotor, it is characterized in that, be provided with between described stator and the housing and seal stator can be prevented the into housing of water, also be marked with epoxy resin between described housing and the stator.
This well with Submerged Motor Pumps by a housing is set between stator and housing, make the better tightness of motor, injection ring epoxy resins between housing and stator, play the effect of double seal insulation like this, whole stator is become the integral body that intensity is higher, improved the life-span and the reliability of motor greatly.
With in the Submerged Motor Pumps, described housing adopts stainless steel material to make at above-mentioned well.Because this well is worked in water with Submerged Motor Pumps, the housing that common material is made gets rusty easily in water, and the housing that adopts stainless steel material to make could adapt to the work of water borough chief time.
With in the Submerged Motor Pumps, also be provided with overheat protector at above-mentioned well in the housing of described motor.Make motor reach the requirement of electrical safety performance by overheat protector.
With in the Submerged Motor Pumps, described stator is wound with coil at above-mentioned well.
Compared with prior art, this well can prevent seal stator the into housing of water with being provided with between the stator of Submerged Motor Pumps and the housing, makes the sealing effect of stator better; Between housing and stator, also be marked with epoxy resin, play the effect of double seal insulation, whole stator is become the integral body that intensity is higher, improved the life-span and the reliability of motor greatly.
Description of drawings
Fig. 1 is the structural representation of this well with Submerged Motor Pumps.
Among the figure, 1, the pump housing; 2, housing; 3, stator; 4, rotor; 5, housing; 6, coil.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this well Submerged Motor Pumps, the housing 2 that comprises the pump housing 1 and motor, both fuse the housing 2 of the pump housing 1 and motor, stator 3 that in the housing 2 of motor, is provided with and rotor 4, be provided with between described stator 3 and the housing 2 and stator 3 sealings can be prevented the into housing 5 of water, also be marked with epoxy resin between described housing 5 and the stator 3.
Particularly, housing 5 adopts stainless steel material to make.Because this well is worked in water with Submerged Motor Pumps, the housing 5 that common material is made gets rusty easily in water, and the housing 5 that adopts stainless steel material to make could adapt to the work of water borough chief time.Also be provided with overheat protector in the housing 2 of motor.Make motor reach the requirement of electrical safety performance by overheat protector.Be wound with coil 6 at stator 3.
This well with Submerged Motor Pumps by a housing 5 is set between stator 3 and housing 2, make the better tightness of motor, injection ring epoxy resins between housing 5 and stator 3, play the effect of double seal insulation like this, whole stator 3 is become the integral body that intensity is higher, improved the life-span and the reliability of motor greatly.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, the pump housing morely; 2, housing; 3, stator; 4, rotor; 5, housing; 6, term such as coil, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
