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.
