Abstract

Рабочее колесо для использования в центробежном насосе, содержащее бандаж, имеющий противоположные поверхности, наружную периферийную краевую часть и ось вращения, множество нагнетательных лопаток, расположенных на одной из поверхностей бандажа, проходящих в сторону от оси вращения, при этом каждая нагнетательная лопатка имеет наружную периферийную краевую часть, и множество вспомогательных лопаток, расположенных на другой стороне бандажа, причем каждая вспомогательная лопатка имеет наружную краевую часть, а размер Da от оси вращения до наружной периферийной краевой части бандажа превышает размер Db от оси вращения до наружной краевой части вспомогательных лопаток.
