Abstract

Различные аспекты изобретения направлены на предоставление структур, которые формируют радиальный зазор между импеллером и элементом корпуса насоса, который обеспечивает минимизацию перемещения текучей среды в радиальный зазор способом, который уменьшает влияние на, и последующую деградацию, внутренней поверхности элемента корпуса насоса посредством перемещения абразивных частиц из радиального зазора, которое достигается путем предоставления узла всасывающего впуска импеллера и элемента корпуса насоса, которые находятся под углом от межлопастного пространства насоса к внешней периферии импеллера в направлении от заднего диска рабочего колеса или стороны привода импеллера и к первому концу корпуса насоса, на котором текучая среда вводится в корпус насоса.
