Description

Известны секционные многоступенчатые центробежные насосы с посаженными на одном валу рабочими колесами, с подвод щими и направл ющими лопатками. Однако такие насосы имеют больщой вес и крупные габариты.Multistage centrifugal sectional pumps are known with impellers seated on the same shaft, with feed and guide vanes. However, these pumps have a large weight and large dimensions.

Описываемый насос дл  снижени  веса и уменьщени  габаритов выполнен без промежуточных стенок, отдел ющих одну секцию от другой, а подвод щие и направл ющие лопатки вместе с корпусом объединены в одну деталь.The described pump is designed to reduce weight and reduce dimensions without intermediate walls separating one section from another, and the inlet and guide vanes together with the housing are combined into one piece.

На чертеже изображена секци  насоса.The drawing shows a pump section.

Секционный многоступенчатый центробежный насос состоит из корпуса , выполненного в виде нескольких секций /, соединенных между собой , рабочих колес 2, посаженных на вал 5, направл ющих 4 и подвод щих лопаток 5, объединенных с секци ми 1.A sectional multistage centrifugal pump consists of a body made in the form of several sections I, interconnected, impellers 2 mounted on shaft 5, guide 4 and inlet blades 5 combined with sections 1.

При перекачивании жидкости уплотнение между ступен ми насоса осуществл етс  путем создани  завихрени  в жидкости на задних кромках 6 рабочих колес 2, причем надежность уплотнени  повыщаетс  за счет фасок 7, выполненных на стенках 8 секций 1.When pumping fluid, the seal between the pump stages is accomplished by creating a vortex in the fluid on the rear edges 6 of the impellers 2, and the reliability of the seal is enhanced by chamfers 7 made on the walls 8 of the sections 1.

Описываемый насос позвол ет осуществл ть перекачку загр зненных жидкостей, в том числе содержащих абразивные включени , повышать эксплуатационную надежность, а также удещевл ть и упрощать технологический процесс его изготовлени .The described pump allows pumping contaminated liquids, including those containing abrasive inclusions, to increase operational reliability, as well as to simplify and simplify the process of its manufacture.

Испытани  насоса показали хорощие результаты.Pump tests have performed well.

Предмет изобретени Subject invention

Секционный многоступенчатый центробежный насос с посаженными на одном валу рабочими колесами, а также с подвод щими и направл ющими лопатками, отличающийс  тем, что, с целью снижени  веса и уменьшени  габаритов, он выполнен без промежуточных стенок , отдел ющих одну секцию от другой, а подвод щие и направл ющие лопатки вместе с корпусом объединены в одну деталь.A sectional multistage centrifugal pump with impellers seated on one shaft, as well as with feed and guide vanes, characterized in that in order to reduce weight and reduce size, it is made without intermediate walls separating one section from the other, and The blades and guide vanes together with the body are combined in one piece.
