Устройство относится к гидромашиностроению, в частности к конструкциям центробежных насосов. Для повышения технологичности изготовления и экономичности в эксплуатации центробежный насос содержит корпус со спиральным отводом и рабочее колесо с лопатками и ведущим диском. Спиральный отвод имеет радиальный выход и состоит из спирального сборника и напорного патрубка. Рабочее колесо размещено в спиральном отводе и через ведущий диск связано с приводным валом. Средняя линия напорного патрубка выполнена по лемнискате Бернулли с точкой перегиба, расположенной в наиболее узком сечении. Каждое радиальное сечение внутренней полости спирального сборника образовано отрезком прямой, составляющей острый угол с касательной к поверхности ведущего диска со стороны лопаток в точке на его наружном диаметре и кривой, имеющей только одну точку пересечения с любой из прямых, параллельных оси вращения рабочего колеса.The device relates to hydraulic machine building, in particular to the structures of centrifugal pumps. To improve the manufacturability and efficiency in operation, the centrifugal pump includes a housing with a spiral outlet and an impeller with blades and a drive disk. The spiral tap has a radial outlet and consists of a spiral collector and a discharge port. The impeller is housed in a spiral outlet and is connected to the drive shaft through a drive disk. The middle line of the discharge port is made according to the Bernoulli lemniscate with the inflection point located in the narrowest section. Each radial section of the inner cavity of the spiral collector is formed by a straight line that makes an acute angle with a tangent to the surface of the drive disk from the blades at a point on its outer diameter and a curve that has only one intersection point with any straight line parallel to the axis of rotation of the impeller.
