Abstract
The invention relates to a novel self-cooled submersible sewage pump, which comprises a pump body, an outer cover, an enclosure arranged in the outer cover, a motor arranged in the enclosure and an impeller arranged on a pump shaft and positioned in a hollow cavity of the pump body, wherein the impeller is driven by the motor to rotate; a heat exchange chamber and a cooling chamber are arranged between the pump body and the motor; the cooling chamber is positioned above the heat exchange chamber; a small impeller is arranged at the connection part of the heat exchange chamber and the cooling chamber, and is arranged on the pump shaft; the outer cover is arranged above the cooling chamber; a cooling shell chamber is formed between the outer cover and the enclosure; a water diversion hole communicated with the cooling chamber and a water passage communicated with the heat exchange chamber are formed in the bottom of the cooling shell chamber respectively. According to the novel self-cooled submersible sewage pump, the motor can be cooled by a self-circulating cooling medium, so that the submersible sewage pump can be exposed from water to run safely and efficiently run for a long time, and the motor of the submersible sewage pump is protected from being burnt out by high temperature.
Description
Technical field
The present invention relates to a kind of submerged pump, particularly relate to a kind of from the dirty pump of cooling Novel submarine.
Background technique
Submerged pump is a kind of Pump and Electromotor disjunctor, and the pump series products worked under simultaneously slipping into liquid, the materials such as sewage medium-length fibre, bag, band, grass, cloth can be torn, cut off, then smooth discharge, is suitable for carrying the liquid containing rigid solid, fibre object and dirty especially, sticky, sliding liquid.
Submerged pump burns out for avoiding motor to heat up in the course of the work, need to cool it, the work of can not surfacing for a long time by fed sheet of a media cooling motor of common submerged pump, or at the additional cooling lagging fed sheet of a media of motor by carrying out cooling motor in Pipeline transport to case, but because fed sheet of a media is sewage mostly, easy blocking pipeline, and also easy precipitated solid impurity bottom cooling lagging, not only can not cooling motor after long-time, make the more difficult heat radiation of motor on the contrary, burn out motor.
Because above-mentioned defect, the design people, actively in addition research and innovation, a kind of from the dirty pump of cooling Novel submarine to founding, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide and a kind of can realize self-loopa cooling medium carry out cooling motor from the dirty pump of cooling Novel submarine, ensure its surface for a long time work time can safe operation.
The one that the present invention proposes is from the dirty pump of cooling Novel submarine, comprise the pump housing, outer cover, be arranged on the casing in described outer cover, be arranged on the motor in described casing, to be installed on pump shaft and to be positioned at the impeller of hollow cavity set by the pump housing, described impeller is driven by motor and rotates, it is characterized in that: between the described pump housing and motor, be provided with heat exchange chamber and cooling chamber, described cooling chamber is positioned at above described heat exchange chamber, described heat exchange chamber and cooling chamber connecting place are provided with small impeller, described small impeller is arranged on pump shaft, described outer cover is arranged on above described cooling chamber, cooling shell room is formed between described outer cover and casing, the priming hole be communicated with described cooling chamber and the waterway be communicated with described heat exchange chamber is respectively arranged with bottom described cooling shell room.
Further, described outer cover sidewall is also provided with osculum and exhaust port, described osculum is communicated with cooling shell room with exhaust port, and described osculum and exhaust port are provided with catch.
By such scheme, the present invention at least has the following advantages: the present invention adopts self-loopa cooling structure, cooling motor is carried out by small impeller to the cooling medium in cooling shell room conveying cooling chamber during use, then the hot cooling medium at motor cooling shell room place is delivered to heat exchange chamber by waterway, lowered the temperature to it by fed sheet of a media, be transported to again in cooling chamber, cooling shell room is flowed to by small impeller, iterative cycles like this carrys out cooling motor, ensures that it can safe operation when surfacing for a long time.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
