Description
Technical field
The utility model relates to a kind of direct current miniature immersible pump, affiliated machinery manufacturing technology field.
Background technique
The direct current miniature immersible pump generally is applied to field showering arrangement and open-air truck washing device etc., and at present, the minisize dc submersible pump on the market generally comprises it and comprises the pump housing, has the spiral hydroecium in the described pump housing, be provided with motor in the pump housing, motor output end is connected with impeller, and impeller is in the spiral hydroecium; Its water intake all is provided in a side of the impeller opposite side with the motor symmetry.Pump working is that the high-pressure water flow that the impeller rotation produces is discharged in the same way from motor drive direction, and the single rubber sealing structure of motor output shaft end also bears high pressure simultaneously, and under the high pressure conditions, the water-proof performance of motor will reduce, and the submersible pump functional reliability is descended; Because motor is wrapped in by the rubber and the plastics pump housing, the heat dispersion of the motor of reduction is easy to make motor overheating, reduces working life.
The model utility content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides the direct current miniature immersible pump of a kind of water proofing property height, perfect heat-dissipating, to improve its ride quality and to increase the service life.
For achieving the above object, the utility model by the following technical solutions: a kind of direct current miniature immersible pump, it comprises the pump housing, has the spiral hydroecium in the described pump housing, is provided with motor in the pump housing, motor output end is connected with impeller, impeller is in the spiral hydroecium; Pump housing position corresponding between motor and the impeller is provided with water intake; The motor front end is covered with the motor radiating cover; Be respectively equipped with Sealing between motor radiating cover and the motor output shaft; Be provided with rubber seal between the motor radiating cover outside and the pump housing inboard; Be provided with circular type sponge filter screen between water intake and the spiral hydroecium.
Described water intake is made up of several small sircle holes.The circle cover that described motor radiating cover is an aluminum alloy material.Motor radiating overlaps pairing pump housing inner side and has the conical surface, and the described motor radiating cover outside has the conical surface, and described rubber seal is between the conical surface and the conical surface outside the motor radiating cover of pump housing inboard.
Adopt such scheme, water intake is arranged on corresponding pump housing position between motor radiating cover and the spiral hydroecium, the high-pressure water flow that the driven by motor impeller revolves generation is at a high speed directly discharged to water outlet by the spiral hydroecium, high-pressure water flow can to outside motor radiating cover and motor output shaft sealing configuration and the motor radiating cover and the seal ring between the pump housing inboard not cause impacting with high pressure.Current moment in the spiral hydroecium discharges, and impels motor radiating cover to the current in the water intake forefoot area also to flow into the spiral hydroecium rapidly, because the flow at high speed of current, will cause motor radiating cover hydraulic pressure subnormal pressure to the water intake forefoot area.Seal ring water-proof performance between favourable raising motor radiating cover and motor output shaft sealing configuration and the motor radiating cover outside and the pump housing inboard.
Water movement, the heat that machine operation produces is also taken away by current by the motor radiating cover, thereby falls your low machine operation temperature, improves the reliable operation performance, prolongs the water pump life-span.
