Abstract

Согласно изобретению предложено рабочее колесо 40 для использования в центробежном насосе 10, включающем кожух 12, имеющий внутри него камеру 20, вход для подачи материала, накачиваемого в камеру, и выход для выпуска материала из камеры, причем рабочее колесо 40 установлено для вращения при использовании в камере вокруг оси вращения и содержит передний кожух 50 и задний кожух 51, каждый из которых имеет основную внутреннюю поверхность в плоскости, по существу, под прямым углом к оси вращения и множество насосных лопастей 42, расположенных между ними, и имеющих, каждая, переднюю кромку 43 в области входа рабочего колеса и заднюю кромку 44, при этом передний кожух 50 имеет дугообразную внутреннюю поверхность в области входа 48 рабочего колеса, которая имеет профиль, определенный следующим:где ось Yнаходится в плоскости основной внутренней поверхности заднего кожуха, ось хсосна с осью вращения и yравна y/(0,5 × D), и xравна Х/В, причем x и y определяют фактические координаты дугообразной внутренней поверхности переднего кожуха рабочего колеса, D, который является наружным диаметром рабочего колеса, составляет 550 мм, и В, которая является шириной выхода рабочего колеса, составляет 72 мм.
