Description

Изобретение относитс  к насосо ,строению и может быть использовано в металлургическом производстве дл  перекачивани  расплавленных металлов .5
Известен осевой насос,который может быть использован дл  перекачивани  расплавленных металлов, содержащий корпус и установленное в нем с зазором консольно рабочее колесо с 10 обечайкой по наружному диаметру l.
Недостатком известного насоса  вл етс  то, что расплавленный металл , попада  в зазор между корпусом и обечайкой, остывает, образу  нас- |5 тыли, вследЬтвие чего снижаетс  надежность насоса .
Цель изобретени  - повышение надежности путем посто нной подачи расплавленного металла равномерно 20 по всему зазору.
Цель достигаетс  тем, что в обечайке выполнены сквозные отверсти , расположенные р дами по всей ее длине .25
На чертеже представлен осевой насос дл  перекачивани  расплавленных металлов.
Насос содержит корпус 1 и уста- i новленное в нем с зазором 2 консоль-30
но рабочее колесо 3 с обечайкой 4, установленной по наружному диаметру колеса 3.
В обечайке 4 выполнены сквозные отверсти  5, расположенные р дами по всей ее длине.
При враглении рабочего колеса 3, расплавленный металл всасываетс  во внутреннюю полость колеса и перемещаетс  в осевом направлении. Под действием центроСежной силы расплавленный металл вьщавливаетс  через отверсти  5 обечайки 4 рабочего колеса 3 в зазор 2 между обечайкой 4 и корпусом 1. Между наружной поверхностью обечайки 4 и внутренней поверхностью корпуса 1 создаётс  повышенное давление, удерживающее рабочее колесо 3 от соприкосновени  с корпусом 1 образу  подшипник жидкостного трени .
Кроме того, расплавленный гор чий металл, проника  через сквозные отверсти  5 в- зазор 2, расплавл ет образующиес  в зазоре в результате охлаждени  от корпуса 1 настыли и уносит их в нагнетательный тракт.
В результате этого значительно повышаетс  нгщежность насоса.
