Изобретение относитс  к области энергомашиностроени  и касаетс  диффузорных выхлонных натрубков турбин, компрессоров, нагнетателей и т. д.The invention relates to the field of power engineering and concerns diffusor exhaust pipe of turbines, compressors, blowers, etc.

Известны диффузоры со щел ми .на стенках дл  отсоса пограничного сло .Known diffusers with crevices on the walls for suction of the boundary layer.

Предложенный диффузор отличаетс  тем, что в Нем установлена но крайней мере одна лопатка с отверсти ми на -поверхности разрежени , которые соединены со ш,ел ми дл  отсоса шограничного сло .The proposed diffuser is distinguished by the fact that there is at least one blade installed in it with openings on the suction surface, which are connected to the needles for suction of the boundary layer.

Это нозвол ет повысить эффективность диффузора .This may increase the efficiency of the diffuser.

На чертеже показан предложенный диффузор .The drawing shows the proposed diffuser.

В проточной части 1 диффузора установлена но крайней мере одна лопатка 2, выполненна , например, в виде полого кольцевого крыла. Лопатка 2 закреплена с помощью стоек 3. На новерхности 4 разрежени  лопатки 2 Выполнены отверсти  а. Кольнова  н;ельIn the flow part 1 of the diffuser, at least one blade 2 is installed, made, for example, in the form of a hollow annular wing. Shoulder 2 fixed with racks 3. On the surface 4 dilution of the blade 2 Holes are made a. Kolnova n; spruce

б дл  отсоса нограннчного сло  расположена на новерхности диффузора в нредотрывной области. Щель б сообщаетс  с отверсти ми а каналом в, расположенным за нределами проточной части диффузора н каналом г, размеП1енным в теле стоек 3.b for suction of the base layer is located on the surface of the diffuser in the pre-cut region. The slit b communicates with the apertures a channel b, located beyond the flow path of the diffuser and the r channel, located in the body of the pillars 3.

При прохождении через диффузор рабочей среды на поверхности 4 лопатки 2 создаетс  местное разр жение, вследствие чего отсасываетс  пограничный слой через щель б, каналы в н г, зат гиваетс  отрыв нотОКа и уменьнгаютс  потери в диффузоре.When passing through the diffuser of the working medium on the surface 4 of the blade 2, local discharges are created, as a result of which the boundary layer is sucked through the slit b, the channels in n g, the separation of the notochos is delayed and the losses in the diffuser are reduced.

Диффузор со щел ми на стенках дл  отсоса пограничного сло , отличают ийс  тем, что, с целью повышени  экономнчностн, в диффузоре установлена по крайней мере одна лопатка , на Поверхности разрежепи  которой выполнены отверсти , сообпдающнес  со щел ми.A diffuser with slots on the walls for the suction of the boundary layer is distinguished by the fact that, in order to increase the efficiency, at least one blade is installed in the diffuser, on the suction surface of which there are holes that coexist with the slots.
