Abstract
The utility model relates to a novel water-cooling water pump. The pump is provided with an impeller that is arranged inside a shell body and can rotate with an electric motor synchronously. The utility model has the advantages that the channel inside the front and the back end covers is connected with the sealed single-layered channel inside the electric motor, and in this way, the water pump itself can generate a flowing stream to cool off the electric motor through the electric motor, thereby achieving an excellent cooling effect and prolonging the service life of the water pump. The utility model is widely applicable to the pressurization system for conveying liquids of various types.
Description
Affiliated technical field
The utility model belongs to a kind of novel water-cooled water pump.
Background technique
Can say so, today, too busy to get away water pump was we can say in people's the improvement of life, and this pump can be extracted into eminence to the water of lakebed and store from the bottom, for people to use by pipeline then.Water utility utilizes a large amount of water of this pump handle to be extracted into eminence just to produce huge pressure and be transported to huge numbers of families.The normal power generation of people's field irrigation, the cooling of the boiler of factory, power large-scale electric generating station etc. all be unable to do without the proper functioning of this water pump.This water pump comprises that is contained in a revolvable impeller in the housing, and impeller links to each other with a motor by rotatingshaft, and the impeller that drives coaxial rotation when the motor high speed rotating rotates, thereby makes impeller-driven liquid make it to produce powerful pressure difference and produce mobile.Can see, under general situation,, thereby be subjected to liking of users because the electrically driven (operated) pump efficiency height of this usefulness is easy for installation, cheap, easy to maintenance.But, under certain situation, thisly just having showed deficiency in its design by motor-driven water pump, this is because the motor of this water pump is air-cooled, that is to say it is that a fan blade of motor afterbody produces cooling blast and makes motor obtain cooling.This design is its shortcoming and not obvious on the water pump of short time work, because the also inreal heating of motor has just quit work.If work for a long time with this water pump, the cooling blast that the fan blade of motor afterbody produces just is not enough to reduce the temperature that it continues rising, finally causes motor self temperature too high, and its inner isolation layer is dissolved, cause the motor short circuit, thereby motor is burnt out by electric current.We can say that most the damage by this motor-driven water pump finally all causes for above-mentioned reasons.The designer has designed several water-cooled water pumps for this reason, as submersible pump, the pump of swimming, be appreciated that thisly directly motor to be immersed in water pump in the liquid, because its refrigeration performance excellence, thereby its efficient is higher, long service life.But, to carry for the supercharging liquid phase of long-range conveying, this water pump just can't be brought into play its unique function.Thereby above-mentioned several water-cooled water pumps still can not change the technical bug of existing water pump.
Summary of the invention
The purpose of this utility model just provides a kind of novel water-cooled water pump, the working life that can improve common water pump.
Water pump of the present utility model links to each other with motor casing with its pump housing, designed the water guide layer of a hollow sandwich sealing configuration in the motor casing, the high-pressure water flow that is produced by water pump vane is directly flowed out from the back aqueduct through the water guide layer in the motor casing, current are fast more, its cooling effect is good more, thereby can change the cooling effect of motor fully, has prolonged working life, even the phenomenon that motor overheating burns can not take place in running yet for a long time.
The utility model is owing to designed the water guide layer of hollow sealing sandwich-type in the motor shell, changed the long-time operated motor temperature drift of common air-cooled water pump, and the shortcoming of burning easily, cooling effect and its working life of motor have been improved, can be widely used in the conveying, pressurization system of various normal temperature liquid, and will produce positive society and economy benefit.

Embodiment
Describe concrete device and the implementation detail that the utility model proposes in detail below in conjunction with above-mentioned accompanying drawing.The utility model comprises that one is equipped with the motor front cover (7) of impeller (6) and the back end cover for motor (2) of water outlet (1) is housed, and the centre is a motor that includes rotor (3) and lead (4).Be appreciated that motor links to each other with impeller (6) by transmission shaft, in the shell of motor, designed the sealing water channel (5) of a sandwich-type, the water route in this water channel (5) and front and rear cover (7), (2) communicates.The internal layer of above-mentioned sandwich-type sealing water channel (5) has supporting base (9) to link to each other with skin, to improve integral intensity.When driven by motor impeller (6) rotated, current can enter from water intake (8), and through motor sandwich-type sealing water channel (5), the water outlet (1) from rear end cover (2) flows out at last under impeller (6) action of centrifugal force.A large amount of heats of producing at work of motor are all taken away by the current that motor self pressurization produces like this, thereby have guaranteed the using effect that it is good, have prolonged its working life.
Claims (2)
1, water-cooled novel water pump, this water pump comprises an impeller that is contained in the housing, and and the synchronous motor that rotates of impeller, motor and water pump fit together, it is characterized in that: an impeller (6) that rotates with motor synchronous is installed in the front cover (7), the water intake (8) of above-mentioned end cap (7) links to each other with outer intake pipe by flange, design has the water route that communicates with water outlet (1) in the rear end cover (2), design has sandwich-type sealing water channel (5) on the motor, and the interior sealing water channel (5) of the water intake (8) of above-mentioned front cover (7) and the water outlet (1) of rear end cover (2) and motor communicates.
2, water-cooled novel water pump according to claim 1 is characterized in that: have at least three supporting bases (9) that the motor internal layer is linked to each other with skin in the sandwich-type sealing water channel (5).
