| 摘要 |
<p>The invention relates to a submersible-motor pump comprising an electric drive motor, below which the casing of a centrifugal pump is attached, the casing (15) of the motor being externally surrounded coaxially by a cooling jacket (16) through which the flow medium flows. The outlet of the cooling jacket annulus (17) is formed by a pipe (40) which is inserted in the cooling jacket annulus (17) axially parallel to the pump axis and extends from the partition (43) between pump casing (3) and motor as far as the topmost region of the annulus (17). <IMAGE></p> |
