Abstract

Раскрыт корпус насоса, предназначенный для центробежного насоса такого типа, который используют для обработки абразивных суспензий, имеющий по меньшей мере одну сторону или боковую облицовку, которая имеет продолжающийся радиально участок, ориентированный в направлении к водорезу корпуса насоса для локализации абразивного износа, создаваемого абразивньми суспензиями на стороне корпуса насоса. Боковая облицовка насоса выполнена с кромкой внешнего контура, которой придана некруглая форма. Корпус насоса предпочтительно может быть выполнен с конфигурацией открытого водореза или с использованием другой соответствующей конфигурации для локализации износа на стороне корпуса.
