Abstract

Описана крыльчатка насоса, имеющая задний кожух, имеющий внутреннюю главную сторону с наружной периферийной кромкой и центральной осью, при этом в процессе эксплуатации крыльчатка может вращаться вокруг центральной оси в одном из направлений вращения, множество лопастей насоса, отходящих от внутренней главной стороны заднего кожуха и расположенных на определенном расстоянии друг от друга, при этом каждая лопасть имеет противоположные первую и вторую боковые стороны, переднюю кромку в области центральной оси и заднюю кромку в области наружной периферийной кромки заднего кожуха, и канал между соседними лопастями насоса, при этом первая боковая сторона на передней кромке лежит в плоскости, расположенной под острым углом к плоскости внутренней главной стороны заднего кожуха, а первая боковая сторона на задней кромке лежит в плоскости, расположенной под тупым углом к плоскости внутренней главной стороны заднего кожуха.A pump impeller is described having a rear casing having an inner main side with an outer peripheral edge and a central axis, while during operation the impeller can rotate around a central axis in one of the rotation directions, a plurality of pump blades extending from the inner main side of the rear casing and located at a certain distance from each other, with each blade having opposite first and second sides, a leading edge in the region of the central axis and a trailing edge in the region of the outer peripheral edge of the rear casing, and the channel between adjacent pump blades, the first side on the front edge lying in a plane located at an acute angle to the plane of the inner main side of the rear casing, and the first side on the rear edge is in the plane located under obtuse angle to the plane of the inner main side of the rear casing.
