Abstract
Ступень центробежного скважинного насоса, включающая рабочее колесо, состоящее из ведущего и ведомого дисков с расположенными между ними лопатками, приемный и выкидной направляющие аппараты со спиральными лопатками и устройство, создающее подпор в зоне входа жидкости в канал рабочего колеса, отличающаяся тем, что устройство, создающее подпор, выполнено в виде многозаходного винта, втулочная основа которого снабжена буртиком, жестко соединенным с выкидным направляющим аппаратом, плавно сопряженным со стороны всасывания с цилиндрическим участком втулочной основы и образующим с торцом винта кольцевое фигурное пространство, причем на цилиндрическом участке втулочной основы выполнены наклонные тонкостенные ребра, имеющие направление навивки, противоположное вращению рабочего колеса с углом подъема винтовой линии, равным 40…45°, и выступающие за пределы втулочной основы.The stage of a centrifugal borehole pump, comprising an impeller consisting of a driving and driven disks with vanes located between them, a receiving and flow guide vanes with spiral vanes, and a device that creates a back up in the area of fluid inlet into the channel of the impeller, characterized in that the device that creates the support is made in the form of a multi-start screw, the sleeve base of which is provided with a shoulder rigidly connected to the flick guide device, smoothly conjugated from the suction side with a cylindrical m section of the sleeve base and forming a ring-shaped space with the end of the screw, moreover, inclined thin-walled ribs are made on the cylindrical section of the sleeve base, having a winding direction opposite to the rotation of the impeller with a helix angle of 40 ... 45 ° and protruding beyond the sleeve base .
