Description

(54) ПАРЦИАЛЬНАЯ ТУРБИНА(54) PARTIAL TURBINE

патрубка 5. При этом уменьшаетс  yronoi2 c 2 потока на выходе, что приводит к увеличению угла поворота потока в рабочем колесе и росту работы газа на окружности колеса.pipe 5. At the same time, yronoi2 c 2 stream at the outlet decreases, which leads to an increase in the angle of rotation of the stream in the impeller and an increase in the work of gas on the wheel circumference.

Одновременно отсос газа из отверстий 7 увеличивает разрежение в полости рабочего колеса и приводит к снижению вентил ционных потерь, введение дополнительного количества рабочего тела через каналы 3 и 6 увеличивает степень впуска, что снижает краевые потери. Одновременно снижаетс  скорость газа на входе рабочего колеса, а этр снижает потери с выходной скоростью при работе на левой ветви характеристик.At the same time, the gas suction from the holes 7 increases the vacuum in the cavity of the impeller and leads to a decrease in ventilation losses, the introduction of an additional amount of working fluid through the channels 3 and 6 increases the degree of intake, which reduces the edge loss. At the same time, the gas velocity at the impeller inlet decreases, and the etr reduces losses with output speed when operating on the left branch of the characteristics.

Измен   положение заслонки 8 можн добитьс  оптимального распределени  отборов из патрубка 5 и отверстий 7.By changing the position of the flap 8, it is possible to achieve an optimal distribution of samples from the nozzle 5 and the openings 7.

Claims (2)

1. Парциальна  турбина, содержаща  рабочее колесо и эжекторный сопловый аппарат с высоконапорным соплом и двухканальным низконапорным соплом, внутренний канал которого подключен обводным трактом к выхлопному патрубку, отличаю ща с  тем, что, с целью повышени  экономичности, внешний канал низконапорного сопла сообщен на входе с атмосферой , а в противолежащей колесу jiiTeHKe тракта выполнены отверсти .1. A partial turbine containing an impeller and an ejector nozzle apparatus with a high-pressure nozzle and a two-channel low-pressure nozzle, the internal channel of which is connected to the exhaust nozzle by a bypass path, characterized in that atmosphere, and in the path opposite to the jiiTeHKe wheel holes are made. 2. Турбина по п. 1, отличаю щ а   с   тем, что в тракте установлена заслонка дл  перераспределени  отборов из патрубка и через отвеости .2. Turbine according to claim 1, characterized by the fact that a valve is installed in the path for redistributing samples from the nozzle and through holes. 5 Источники информации, прин тые во внимание при экспертизе5 Sources of information taken into account in the examination 1.Емин О.Н. и др.
