Abstract
The invention discloses a turboset high-pressure part structure with a cylindrical inner shell, which comprises a high-pressure inner shell upper half, a high-pressure inner shell lower half, a first tangential steam inlet pipe and a second tangential steam inlet pipe. The turboset high-pressure part structure is characterized in that the first tangential steam inlet pipe and second tangential steam inlet pipe are respectively installed on the high-pressure inner shell lower half. Compared with the set in the upper/lower tangential steam inlet structure, the cylindrical shell in the double-lower-part tangential steam inlet structure can effectively lower the integral shipping height by about 700mm, thereby effectively avoiding the possible risks in the transportation process. The turboset high-pressure part structure saves unnecessary cost, helps the power plant to achieve the goal of shortening the installation period in deed, and maximally displays the advantages of the integral shipping set.
Description
Technical field
The present invention relates to steam turbine internal structure, specifically a kind of steam turbine set high-pressure section structure with tubular inner casing.
Background technique
A new generation 660MW and above grade thermoelectricity ultra supercritical high pressure are divided in cylinder unit, for effectively solving casing split problem on deformation, further lifting unit economy, high-pressure inner cylinder have employed barrel-type casing structure, by extremely on-the-spot for the delivery of high-pressure modular entirety during installation, the on-the-spot positioning instant that only need complete high-pressure modular entirety can, shorten the in-site installation duration.But high-pressure modular adopts conventional tangential admission structure up and down, in transportation process, part power plant due to the traffic condition by the limit for height such as tunnel, bridge as railway or highway affect, have to build special transport road voluntarily or make high-pressure modular pass through restricted section of road by big machinery lifting appliance, not only considerably increase the operational risk of lifting transport in transport process, also consume the huge financial resources of power plant, material resources simultaneously.The advantage which results in the delivery of high-pressure modular entirety can not farthest be embodied.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, thering is provided a kind of is the steam turbine set high-pressure section structure of two inlets admission with tubular inner casing bottom, make the delivery of high-pressure modular entirety little to on-the-spot transport restrictions, the on-the-spot positioning instant that only need complete high-pressure modular entirety can, shorten the in-site installation duration, improve working efficiency, reduce cost of production.
Realizing technological scheme of the present invention is: a kind of steam turbine set high-pressure section structure with tubular inner casing, comprise high-pressure inner cylinder first, high-pressure inner cylinder second, the first tangential admission pipe and the second tangential admission pipe; It is characterized in that: described first tangential admission pipe and the second tangential admission Guan Jun be installed on high-pressure inner cylinder second.
Described first tangential admission pipe and the second tangential admission Guan Jun are installed on second both sides of high-pressure inner cylinder, and the mouth of pipe down.
Described first tangential admission pipe and the second tangential admission pipe and high-pressure inner cylinder second, high-pressure inner cylinder first to form high-pressure modular overall.
The invention has the beneficial effects as follows:
1, compared to the unit of upper and lower tangential admission structure, the barrel-type casing of the two lower tangential admission structures in the present invention effectively can reduce overall delivery highly about 700mm, has effectively evaded issuable risk in transport process.
2, saved unnecessary expense, the real power plant that helps achieves the object shortening installation period, has farthest given play to the advantage of overall delivery unit simultaneously.

Embodiment
As shown in Figures 4 to 6: a kind of steam turbine set high-pressure section structure with tubular inner casing, comprise high-pressure inner cylinder first 1, high-pressure inner cylinder second the 2, first tangential admission pipe 3 and second tangential admission pipe 4; Described first tangential admission pipe 3 and the second tangential admission pipe 4 are all installed on second both sides of high-pressure inner cylinder, and the mouth of pipe down.Described first tangential admission pipe 3 and the second tangential admission pipe 4 and high-pressure inner cylinder second 2, high-pressure inner cylinder first 1 forms high-pressure modular 5 entirety.
Compared to the unit of upper and lower tangential admission structure as shown in Figure 1 to Figure 3, the barrel-type casing of the two lower tangential admission structures in the present invention effectively can reduce the overall highly about 700mm that delivers, and has effectively evaded issuable risk in transport process.Saved unnecessary expense, the real power plant that helps achieves the object shortening installation period, has farthest given play to the advantage of overall delivery unit simultaneously.
Compared to the unit of upper and lower tangential admission structure, efficiency of the present invention may reduce, stability possible deviation, therefore, generally believe in the industry unit of upper and lower tangential admission structure can not be changed into by two tangential admission Guan Doukai cylinder second.For comprehensive unit economy and stability are considered, practical by following calculating comparative illustration the present invention program:
1, contrast the admission flow field of two kinds of tangential admissions, lower tangential admission is slightly poor;
Simultaneously:
2, calculating contrast has been done to the stage efficiency of high-pressure cylinder chopped-off head, no significant difference;
3, calculating contrast has been done to the cylinder efficiency of whole high-pressure cylinder, no significant difference;
4, the cylinder stability after the change of docking port position has done calculation on Construction again, and result is qualified, meets the demands.
The comprehensive above conclusion that calculates is learnt, after upper and lower tangential admission changes lower tangential admission structure into, slightly affects the high-pressure modular Economy of unit, but very little; And stability still meets the demands.Thus, implement lower tangential admission structure, advantage of the present invention can be given full play to.
