Abstract
The utility model provides the attachment structure of motor and the pump housing in a kind of deep well pump, belongs to fluid machinery technical field.It solves the problems, such as that the inconvenient service life of existing deep well pump installation is short and radiating effect is poor.The attachment structure of motor and the pump housing in this deep well pump, including the pump housing and the motor being arranged in the pump housing, the housing of motor is outwardly uniformly to form some groups of limited blocks, it is integral type structure between limited block and electric machine casing, the stopper slot being engaged with limited block is offered on the inwall of the pump housing, and coordinate between limited block and stopper slot for gap, being also sticked between the housing of motor and the contact surface of pump housing inwall has heat-conducting silica gel sheet.The utility model has the advantages of reduction production difficulty easy for installation and longer service life.
Description
Technical field
The utility model belongs to fluid machinery technical field, is related to a kind of deep well pump, electric in more particularly to a kind of deep well pump
The attachment structure of machine and the pump housing.
Background technology
Deep well pump is that motor and water pump direct-connected integrated pull the plug the water lift equipment of work.Motor and pump in deep well pump at present
Typically by being fixed in sealing nut in motor head between body, because water pump produces vibrations, therefore nut in the process of running
Easily loosening causes motor entering water and damages, and on the other hand, the radiating of motor is all to be conducted to pump by motor casing in deep well pump
Body, then be dispersed into by the pump housing in water, and heat conduction typically is realized by being fitted close between motor casing and the pump housing, therefore contact
Easily gap be present and reduce radiating effect in face.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of fixed effect is more preferable
And the attachment structure of motor and the pump housing in the more preferable deep well pump of heat dispersion.
The purpose of this utility model can be realized by following technical proposal：The connection of motor and the pump housing in a kind of deep well pump
Structure, including the pump housing and the motor that is arranged in the pump housing, it is characterised in that the housing of the motor is outwardly uniform to be formed
Some groups of limited blocks, be integral type structure between described limited block and electric machine casing, offered on the inwall of the pump housing with
The stopper slot that limited block is engaged, and coordinate between limited block and stopper slot for gap, housing and the pump housing inwall of the motor
Contact surface between be also sticked and have heat-conducting silica gel sheet.
Its technique effect of the attachment structure of motor and the pump housing is in this deep well pump：Consolidated by the cooperation of limited block and stopper slot
It is fixed to replace traditional screw to fix, the production used time easier for installation for effectively reducing manual assembly is made it have, tool
There is the advantages of production efficiency is higher, traditional screw, which is fixed, has the defects of loosened screw after water pump long-term use is brought and safety
Hidden danger, the attachment structure can make water pump service life longer and improve security.
Further, heat is generally conducted to the pump housing by deep well pump by electric machine casing, then is dispersed into by the pump housing in water,
And the direct contact progress heat of electric machine casing and the pump housing conducts its contact surface and certainly exists thermal contact resistance, heat is hindered to contact
Transmission between face, by the heat-conducting silica gel sheet that is sticked the transmission effect of heat between the two can be made more preferable, be effectively increased
The thermal diffusivity of the pump housing, it is corresponding and its service life can be increased, wherein heat-conducting silica gel sheet can also to a certain extent by
Radian manufacturing tolerance between electric machine casing outer wall and pump housing inwall makes up, and it is difficult equivalent to production is reduced to reduce technological requirement
Degree.
In a kind of above-mentioned deep well pump in the attachment structure of motor and the pump housing, described spacing number of blocks is 4 groups.
In a kind of above-mentioned deep well pump in the attachment structure of motor and the pump housing, the top of the electric machine casing is also welded with
Protective cover.
In a kind of above-mentioned deep well pump in the attachment structure of motor and the pump housing, described motor is brshless DC motor.
Compared with prior art, the attachment structure of motor and the pump housing has reduction production difficulty easy for installation in this deep well pump
And the advantages of service life is longer.
Brief description of the drawings
Fig. 1 is this motor and pump housing attachment structure schematic diagram.
In figure, 1, the pump housing；2nd, motor；3rd, limited block；4th, heat-conducting silica gel sheet；5th, protective cover.
Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, the attachment structure of motor and the pump housing in this deep well pump, including the pump housing 1 and the electricity that is arranged in the pump housing 1
Machine 2, the housing of motor 2 is outwardly uniformly to form some groups of limited blocks 3, is integral type between limited block 3 and the housing of motor 2
Structure, the stopper slot being engaged with limited block 3 is offered on the inwall of the pump housing 1, and match somebody with somebody between limited block 3 and stopper slot for gap
Close, being also sticked between the housing of motor 2 and the contact surface of the inwall of the pump housing 1 has heat-conducting silica gel sheet 4.
Further describe in detail, in order that fixed effect is more preferable, the quantity of limited block 3 is 4 groups；Also weld the top of the housing of motor 2
Have protective cover 5, by protective cover 5 can effectively reduce deep-well impeller of pump rotate when bring to the inside rotor component of motor 2
Axial thrust；Wherein the motor 2 is brshless DC motor.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more having used the terms such as the pump housing 1, motor 2, limited block 3, heat-conducting silica gel sheet 4, protective cover 5 herein,
It is not precluded from the possibility using other terms.It is new just for the sake of more easily describing and explaining this practicality using these terms
The essence of type；Any additional limitation is construed as all to disagree with the utility model spirit.
