Abstract
The invention discloses a pump body of a shield electric pump. The pump body comprises a main pump body. The main pump body is provided with an inlet end and an outlet end. The inlet end and the outlet end are arranged at the two opposite ends of the main pump body correspondingly. A runner is arranged between the inlet end and the outlet end. The runner communicates with an external motor shell. By the adoption of the technical scheme, the runner communicates with the motor shell. The runner extends towards the motor shell from the inlet end and then rotates to form a snail-shell-shaped rotating part, space is enlarged, and the bearing amount of the pump body is increased. The runner is in a spiral shape so that media can flow slowly conveniently, the runner communicates with the motor shell and participates in exchange of heat in the motor shell, and the media in the runner of the shield electric pump cannot be detained or condensed. A base is further arranged at the bottom of the main pump body, and the extension line of the axis of the base coincides with the axis of the motor shell. The axes coincide with each other, the equipment works stably, and noise cannot be generated during running of the equipment. The base is adopted for connection, so that maintenance and replacement of parts are facilitated.
Description
Technical field
The invention belongs to air-conditioning and manufacture field, it is more particularly related to the pump housing of a kind of shielded electric pump.
Background technology
Shielded electric pump is mainly for delivery of the bigger medium of the temperature difference, this medium with thermal variation flow rate passes in and out the pump housing lentamente, the time that medium is detained in pump housing runner is long, require that the pump housing has certain bearing capacity and resistance to difference variation, angle and the length of the runner of the shielded electric pump of prior art are limited in space, it sometimes appear that the phenomenon be detained or condense.
Summary of the invention
The technical problem to be solved is to provide the pump housing of a kind of shielded electric pump avoided shielded electric pump runner medium to be detained or condense.
To achieve these goals, the technical scheme that the present invention takes is the pump housing of a kind of shielded electric pump provided, including pump housing body, described pump housing body is provided with entrance point and the port of export, wherein entrance point is respectively placed in the two ends that pump housing body is relative with the port of export, runner, runner and external electric machine casing UNICOM it is provided with between entrance point and the port of export.
The pump housing of a kind of shielded electric pump disclosed by the invention, runner rotates after entrance point extends to electric machine casing and forms Crusta Limax shape rotating part, and the other end of rotating part extends to follow-up the reneing of low side of pump housing body and extends the port of export to the direction away from electric machine casing.
The pump housing of a kind of shielded electric pump disclosed by the invention, the rotation portion of runner in the middle part of pump housing body, the extended line of its axis and the dead in line of electric machine casing.
The pump housing of a kind of shielded electric pump disclosed by the invention, the bottom of pump housing body is additionally provided with base, the extended line of base axis and the dead in line of electric machine casing.
The pump housing of a kind of shielded electric pump disclosed by the invention, base is along the cross section of axis in " work " font, and the vertical bar in middle part of " work " word is hollow stem.
Using technical scheme, runner and electric machine casing UNICOM, runner rotates after entrance point extends to electric machine casing and forms Crusta Limax shape rotating part, adds space, increases the bearing capacity of the pump housing；Runner uses helical form, facilitates the sluggish flow of medium, with electric machine casing UNICOM, participates in the exchange of internal heat, it is to avoid shielded electric pump runner medium is detained or condenses；The bottom of pump housing body is additionally provided with base, the extended line of base axis and the dead in line of electric machine casing；Dead in line, stable during equipment work, it is to avoid during equipment operation, to produce noise；Employing base connects, and facilitates maintenance and the replacing of parts.
Below with reference to drawings and Examples, the present invention is described in detail.
