Abstract
An outlet partition plate double-volute-chamber structure is designed for solving the technical problems that turbine rotating machinery in the prior art are incompact in spatial arrangement structure, and particularly an outlet partition plate volute chamber structure on the rotating machinery is unsatisfactory in design so as to increase cost and waste resources. The outlet partition plate double-volute-chamber structure comprises an outlet partition plate body consisting of an outlet partition plate upper portion 1 and an outlet partition plate lower portion 2 by means of splicing; spiral volute chamber flow channels 5 are respectively arranged on plate surfaces on two sides of the outlet partition plate body formed by means of splicing; and the cross sectional sizes of the spiral volute chamber flow channels 5 surrounding the centers of the outlet partition plate surfaces are gradually changed from small to large along a rotating direction. The outlet partition plate double-volute-chamber structure has the advantages of compact structure, smaller cylinder space, reduced integral volume, raw material economization, cost reduction and capabilities of defining the sizes of the flow channels in different sections of volute chambers on a partition plate according to the positions of the outlet partition plate volute chambers and flexibly arranging the positions of the outlet volute chambers.
Description
Technical field:
The utility model relates to a kind of turbo machine spatial arrangement structure, relates in particular to the two volute casing structures of a kind of outlet dividing plate.Be suitable for the application on various turbine rotating machineries.
Background technique:
Turbine rotating machinery spatial arrangement generally all will export the volute casing design on the cylinder body of rotating machinery at present, because structure is not compact, increase the volume and weight of complete machine, not only manufacture cost height, and waste resource.Therefore the quality of the outlet volute casing structural design on the turbine rotating machinery directly influences the quality and the cost of rotating machinery.
Summary of the invention:
The utility model is not compact for the turbine rotating machinery spatial arrangement structure that solves the prior art existence, particularly the outlet dividing plate volute casing structural design on the rotating machinery is undesirable, cause the technical problem that increases cost, the wasting of resources, provide a kind of outlet dividing plate two volute casing structures, it comprises the outlet diaphragm body, described outlet diaphragm body is spliced by outlet dividing plate top 1 and outlet the lower partition 2 two-part, is respectively equipped with helical line type volute casing runner 5 on the biside plate face of the described outlet diaphragm body that is spliced; Described helical line type volute casing runner 5 is around the center of outlet dividing plate plate face, by counterclockwise forming the cross-sectional dimension helical line type volute casing runner of gradual change from small to large.
Characteristics of the present utility model and beneficial effect: adopt the two volute casing structures of outlet dividing plate, because compact structure, cylinder space is less, and machine volume diminishes, and saves raw material, and cost reduces; And can reduce according to outlet dividing plate cost, and can determine the channel size of volute casing different cross section on the dividing plate, the position of flexible arrangement outlet volute casing according to the position of outlet volute casing.

Embodiment:
Referring to Fig. 1-Fig. 3, the two volute casing structures of outlet dividing plate, it comprises the outlet diaphragm body, and described outlet diaphragm body is spliced by outlet dividing plate top 1 and outlet the lower partition 2 two-part, is respectively equipped with helical line type volute casing runner 5 on the biside plate face of the described outlet diaphragm body that is spliced; Described helical line type volute casing runner 5 forms the cross-sectional dimension helical line type volute casing runner of gradual change from small to large around the center of outlet dividing plate plate face by sense of rotation.
Between the biside plate face of described outlet diaphragm body, be distributed with and strengthen gusset 3; On the split between described outlet dividing plate top 1 and outlet the lower partition 2, be provided with ring stiffener 4.
The two volute casing structures of outlet dividing plate, be that two helical line type volute casing runners were located on the plate face of outlet dividing plate top 1 and the bi-side that export the lower partition 2 in 5 minutes, during installation up and down the split of two dividing plates in cylinder body, dock, helical line type volute casing runner on the plate face of outlet dividing plate both sides is docked has simultaneously formed complete helical line type volute casing runner 5.Helical line type volute casing runner 5 forms the cross-sectional dimension helical line type volute casing runner of gradual change from small to large around the center of outlet dividing plate plate face by sense of rotation.Can change the sectional dimension of outlet helical line type volute casing runner 5 according to the difference of turnover pipe.
In order to guarantee to export diaphragm strength and rigidity, in the outlet diaphragm body, promptly between the biside plate face radially the position be distributed with stiffening rib 3, and processing for convenience and installing is provided with annular muscle 4 on the split of outlet dividing plate.
