Abstract

Боковая часть насоса, предназначенная для использования с экранированным рабочим колесом насоса, содержащая секцию боковой стенки, содержащую наружный участок с наружной кромкой в плоскости, который находится, по существу, под прямыми углами к оси вращения, внутренний участок с внутренней кромкой и промежуточный участок между наружным и внутренним участком, наклоненный внутрь от указанной плоскости по направлению ко входной секции, а внутренний участок идет от промежуточного участка в направлении от передней поверхности секции боковой стенки, где наружная поверхность переднего экрана рабочего колеса и задняя поверхность боковой части размещаются так, чтобы быть обращенными друг к другу с зазором между ними, причем задняя поверхность сконфигурирована так, что поперечные размеры зазора возрастают по направлению к оси вращения рабочего колеса на промежуточном участке.A lateral part of the pump intended for use with a shielded impeller of the pump, comprising a side wall section comprising an outer portion with an outer edge in a plane that is substantially at right angles to the axis of rotation, an inner portion with an inner edge and an intermediate portion between the outer and an inner portion inclined inward from said plane toward the inlet section, and the inner portion extends laterally from the intermediate portion in the direction from the front surface of the section wall, where the outer surface of the front screen of the impeller and the rear surface of the side part are placed so as to face each other with a gap between them, and the rear surface is configured so that the transverse dimensions of the gap increase towards the axis of rotation of the impeller in the intermediate section .
