Abstract

В лопастной машине по первому варианту, содержащей корпус с центральным и периферийным каналами пропускания рабочей среды, соединенный с внешней машиной вал, на котором закреплена ступица осевого рабочего колеса, имеющего круговую систему лопастей, последовательно чередующихся вдоль оси вала с круговой системой лопаток направляющего аппарата, закрепленными в корпусе, рабочее колесо снабжено по меньшей мере одной кольцевой втулкой, жестко связанной со ступицей, а круговая система лопастей рабочего колеса и лопаток направляющего аппарата выполнены, по меньшей мере, двухрядными с центральным и периферийным рядами круговых систем лопастей и лопаток, соответственно. Лопастная машина по второму варианту, содержащая корпус с центральным и периферийным каналами пропускания рабочей среды, соединенный с внешней машиной вал, на котором закреплена ступица осевого рабочего колеса, имеющего круговую систему лопастей, последовательно чередующихся вдоль оси вала с круговой системой лопаток направляющего аппарата, закрепленными в корпусе, снабжена вторым рабочим колесом с охватывающей первое рабочее колесо втулкой, кинематически связанной с дополнительным валом, соединенным с внешней машиной, круговые системы лопастей рабочих колес и лопаток направляющего аппарата выполнены трехрядными с периферийным, промежуточным и центральным рядами лопастей и лопаток, соответственно. В каждом из вариантов лопасти рабочего колеса и лопатки направляющего аппарата могут быть выполнены в каждом ряду переменной высоты вдоль втулки. При этом повышены удельная мощность (на единицу массы), полезный напор, а также долговечность приIn the blade machine in the first embodiment, comprising a housing with central and peripheral channels of transmission of the working medium, connected to an external machine shaft, on which is mounted the hub of an axial impeller having a circular system of blades alternately alternating along the shaft axis with a circular system of guide vanes fixed in the housing, the impeller is provided with at least one annular sleeve rigidly connected to the hub, and a circular system of blades of the impeller and vanes of the axle guide that it is made of at least double-row with the central and peripheral systems of circular rows of blades and vanes, respectively. Blade machine according to the second embodiment, comprising a housing with central and peripheral channels of transmission of the working medium, connected to an external machine shaft, on which is mounted a hub of an axial impeller having a circular system of blades alternately alternating along the axis of the shaft with a circular system of guide vanes fixed in housing, equipped with a second impeller with a sleeve embracing the first impeller, kinematically connected with an additional shaft connected to an external machine, circular systems emy impeller blades and guide blades are made from three-row peripheral, intermediate and central rows of blades and vanes, respectively. In each of the variants of the impeller blades and guide vanes can be performed in each row of variable height along the sleeve. At the same time, the specific power (per unit mass), the effective head, as well as the durability at
