Abstract

Устройство для регулировки величины зазора возле торцов рабочих лопаток ротора газовой турбины содержит: три кольцевых канала (14) циркуляции воздуха, установленных по кругу вокруг кольцевого корпуса (12) статора турбины и предназначенных для подачи воздуха на указанный корпус (12) с целью изменения его температуры; по меньшей мере один трубчатый воздухораспределитель (20), по меньшей мере часть которого расположена вокруг каналов (14) циркуляции воздуха; по меньшей мере одну трубу (22) подачи воздуха в трубчатый воздухораспределитель (20); по меньшей мере один воздуховод (24), соединенный с трубчатым воздухораспределителем (20) и с каналами (14) циркуляции воздуха. По меньшей мере один трубчатый воздухораспределитель (20) соединен с тремя воздуховодами (24), каждый из которых соединен с тремя каналами (14) циркуляции воздуха, причем каждый из воздуховодов (24) оборудован диафрагмой (30), которая ограничивает напор воздуха в воздуховоде, причем параметры каждой из диафрагм подобраны индивидуально согласно тому, в котором из воздуховодов (24) установлена указанная диафрагма. Турбомашина содержит по крайней мере одно устройство регулировки величины зазора возле торцов рабочих лопаток ротора.
