Abstract
Изобретение относитс к насосострор нию. Цель изобретени - повышение на дежности Насос содержит рабочее колесо 2 зоны 3, 4 всасывани и нагнетани , вса сывающии раструб 5 и крыльчатку с полыми лопаст ми 7 и стоиками 8, в которых выполнены щели 11, 12 При работе насоса жидкость из зоны 4 нагнетани перепускаетс в лопасти 7 и стойки 8 и истекает из щелей 11, 12 поспедних, создава реактивную струю При этом струи жидкости отбрасывают от раструба образующийс воздушный шнур, предотвраща тем самым попздание воздуха в зону 3 всасывани насоса, повыша i антикавитационный запас последнего 3i iThe invention relates to pumping. The purpose of the invention is to increase reliability. The pump includes an impeller 2 suction and discharge zones 3, 4, a suction socket 5 and an impeller with hollow blades 7 and stoics 8, in which slots 11, 12 are made. When the pump is operating, the fluid from the discharge zone 4 is bypassed in the blades 7 and the pillars 8 and expire from the slots 11, 12 second, creating a jet stream. At the same time the liquid jets reject the air cord formed from the socket, preventing air from entering the pump suction zone 3, increasing i the anti-cavitation reserve of the latter 3i i
