Description

one

The image refers to the parts of the turbine industry, in particular to the low volume of the low pressure part of the turbine turbines.

The exhaust pipes of the Turbom1asch | I "s are known, containing an air diffuser installed in the housing, separating shaped fins located in the horizontal plane of the horizontal connector at half the length of the pipe, and a parallel end wall, key pipe of the 1st campus, which forms equal portions with ribs, and each side section of the wall. reset par.a I13 upper and lower halves of the diffuser.

The purpose of the present invention is to increase the aconomicity due to more rational use of free volume.

nozzle.

This is achieved by the fact that a differential multiplex multi-channel with a sector cut in the walls is, in part, an anti-output output slice.

FIG. 1 shows the proposed pipe, a longitudinal section along the axis of the turbine; in fig. 2 - the same, cross p. Cut; in fig. 3 - the same, horizontal incision of the turbine; in fig. 4 - a. Xonometric the projection of the axial radial diffuser with a sector cutout. Outlet 1PN | Oth branch pipe of the turbos. Machine contains a KOpinyc 1, in which a multichannel axial radial diffuser 2 is installed with a sector cut .3 in the walls in the part opposite to the opposite output slice. The diffuser is made with a horizontal connector on the axis.

In the upper part of the P | tube are located; there are a set of ribs (blades) 4, which are partially 1 cut into the radial part of the diffuser 2 and fixed in the front and rear walls of the housing 1.

Separated profiled ribs

5 are installed at half the horizontal length of the turbine connector and embedded into the axial radial diffuser 2. Vertical partition K, a 6 is located at the lower part of the pipe: which is perpendicular to the torsion axis of the turbine and welded to the top at the full width of the rim M 5 (across the entire width of the pipe. In the plane, perpendicular to the perpendicular pipe. 5) pn partition 6, welded power ribs. a 7, forming additional

diffuser channels.

Profiled ribs 5 and dividing wall

6 form separate compartments for discharge of steam from the upper and lower halves of the diffuser.

The slinging blades of 4 lpdnaznacheniey for; pa, clogging (from the stream to the outlet section of the pipe. Simultaneously, the bay: and serve as force elements, ensuring / their rigidity of the upper half of the pipe.

The flow from the lower side of the diffuser 2 and, p1a, is determined along its output cross section by ribs 7, which together with 5 form a rigid power iwapKac lower T1: 10l0 | c: exhaust pipe.

Paid (At the organization, the flow of Hia is directed mainly to the full use of the explosive cross sections and the elimination of stagnant OWGs and vortex regions.

PREPARATION AND RESULTS

The exhaust pipe of the turbomachine, containing an axle-mounted diffuser, a distributor, a separate separation profile, a and other ribs, is located at a half of the connector for half of the length of the pipe, and a parallel rim, and a horizontal section of the horizontal section of the connector for half the length of the pipe, and a parallel rider, for discharge: a pair of upper and lower halves of the diffuser, characterized in that, for the purpose of | PO (Turbom1a is more economical (Tires, the diffuser is multichannel with sector cut-outs in the portions in the part opposite to bottom slice.
