Abstract
Соответственно данному изобретению рабочее колесо для центробежного насоса включает по меньшей мере одну лопатку, внешняя в радиальном направлении конечная часть которой выполнена такой формы, чтобы создавать профиль распределения скоростей потока, который контролирует и уменьшает износ, вызванный жидкотекучей суспензией, которая вытесняется из рабочего колеса на внутреннюю поверхность корпуса насоса. В конфигурации лопаток рабочего колеса, согласно данному изобретению, в большинстве случаев выполнен участок, который выступает наружу, в отличие от традиционной прямой или вогнутой кромки лопатки рабочего колеса. Форма этого участка, который выступает наружу, может варьироваться, но она выбирается таким образом, чтобы создавать профиль распределения скоростей потока, который уменьшает износ корпуса насоса.
