Description

ми элементами, о т л и ч а ю щ и и с   тем, что, с целью повышени  эффективности охлаладени  рабочей жидкости в зоне ступеней уплотнений, внутри ступени на проставке установлен обтекатель, выполненный в виде кольца, образующего совместно с наружной поверхностью роторного элемента уплотнение, а сквозные пазы в нроставке дл  прохода рабочей жидкости вдоль охлаждаемого корпуса от зоны унлотненп  одной ступени к другой образованы лопатками , расположенными по касательной к внутренней окружности лопаток по направлению враш,ени  потока.elements, so that, in order to increase the efficiency of cooling the working fluid in the area of the sealing steps, inside the step on the spacer is installed a fairing made in the form of a ring, forming together with the outer surface of the rotor element , and the through grooves in the space for the passage of the working fluid along the cooled body from the zone of one stage to another are formed by blades tangential to the inner circumference of the blades in the direction of flow.
