Abstract

Ступень паровой турбины, содержащая диафрагму, рабочие лопатки с бандажами, имеющими осевой гребень со стороны межвенцового зазора, отличающаяся тем, что в межвенцовом зазоре установлено периферийное кольцо, которое выполнено с осевым гребнем, расположенным под осевым гребнем бандажей рабочих лопаток и образующим с ним лабиринтный канал. The stage of a steam turbine containing a diaphragm, rotor blades with bandages having an axial ridge on the side of the interventional gap, characterized in that a peripheral ring is installed in the interventional gap, which is made with an axial ridge located under the axial ridge of the blades of the working blades and forming a labyrinth channel with it .
