Claims (1)

Центробежный компрессор со стабилизирующим поток корпусом содержит установленное с возможностью вращения вокруг оси рабочее колесо со ступицей, по окружности которой расположены рабочие лопатки, окружающий рабочее колесо корпус, который по своему внутреннему контуру соответствует внешнему контуру рабочих лопаток и вместе со ступицей образует проточный канал, проходящий между осевым впускным отверстием и радиальным выпускным отверстием, и проходящие во входной зоне проточного канала в направлении потока стабилизирующие шлицы, которые выполнены в корпусе от его внутреннего контура и распределены по внутренней периферии корпуса. Для расширения стабильного рабочего диапазона в сторону меньших объемных потоков стабилизирующие шлицы расположены относительно рабочих лопаток так, что их обращенный к осевому впускному отверстию передний конец удален в направлении потока на заданный отрезок от входной кромки лопаток.A centrifugal compressor with a flow-stabilizing housing contains an impeller mounted for rotation around an axis with a hub, around the circumference of which are working blades, a housing surrounding the impeller, which along its inner contour corresponds to the outer contour of the blades and forms a flow channel axial inlet and radial outlet, and passing in the inlet area of the flow channel in the direction of flow stabilizing slots, which s in a housing formed on its inner contour and distributed along the inner periphery of the housing. To extend the stable working range towards smaller volumetric flows, the stabilizing slots are located relative to the working blades so that their front end facing the axial inlet is removed in the direction of flow to a predetermined segment from the input edge of the blades.
