Abstract
A low pressure cylinder for turbines comprises an outer cylinder. A stiffener is welded to the external wall of the upper part of the outer cylinder. The technology can prevent the outer cylinder from deformation by increasing its strength and resolves the problem of steam leaking within the low pressure cylinder caused by long operation so that the technology can keep the efficiency of the tank from falling and the coal consumption for electricity generation from increasing.
Description
Technical field
The turbine low pressure cylinder that the utility model relates to is one of parts of Turbo-generator Set, belongs to the technological improvement of turbine low pressure cylinder.
Background technique
Turbo-generator Set comprises high-pressure cylinder, intermediate pressure cylinder, low pressure (LP) cylinder.Enter the steam of high-pressure cylinder, intermediate pressure cylinder, discharge after the work done and enter low pressure (LP) cylinder again, steam promotes the vane rotor rotation in the cylinder, drives generator for electricity generation.During unit operation, the outer in-cylinder pressure of low pressure (LP) cylinder is lower than the cylinder pressure outside, because outer cylinder body is deformed by the external force effect for a long time, causes the inner vapour that leaks, and cylinder efficient is reduced, and causes coal consumption to increase.Show that turbine low pressure cylinder the 5th, 6 extraction steam pipe temperature exceed 20-40 ℃ than normal temperature.According to statistics, the every decline 10% of cylinder efficient, gross coal consumption rate approximately increases 8-9 gram/kw
1About h.
Summary of the invention
The purpose of this utility model provides a kind of turbine low pressure cylinder, and this low pressure (LP) cylinder has solved in work long hours outer shell distortion, the cylinder and leaked the vapour problem, imitates thereby stablize cylinder.
The technical solution of the utility model is: a kind of turbine low pressure cylinder, comprise outer shell, and it is characterized in that: on the upper cylinder body outer wall of outer shell, be welded with stiffening rib.
Because present technique has been welded stiffening rib on the upper cylinder body outer wall of existing turbine low pressure cylinder outer shell, increased the intensity of outer shell, therefore effectively prevented the outer shell distortion, solved in the past because the problem of leaking vapour in low pressure (LP) cylinder outer shell distortion the causing cylinder, make 5,6 extraction steam pipe extraction temperatures stable, maintenance cylinder effect does not reduce, gross coal consumption rate does not increase.
Description of drawings
Below in conjunction with drawings and Examples the utility model technology is further specified.
Fig. 1 is the utility model turbine low pressure cylinder outer shell structural representation.
Fig. 2 is the side view of the utility model Fig. 1.
1 stiffening rib, 2 upper cylinder bodies, 3 steam inlet pipes, 4 extraction steam pipes, 5 extraction steam pipes, 6 flanges, 7 supporting ribs, 8 lower cylinder bodies, 9 support platen, 10 exhaust steam pipes, 11 axis holes among the figure.
Embodiment
Turbo-generator Set comprises high-pressure cylinder, intermediate pressure cylinder, low pressure (LP) cylinder.The outer shell of low pressure (LP) cylinder has upper cylinder body (2) and lower cylinder body (8), last lower cylinder body is connected by flange (6), the cylinder body end face is provided with axis hole (11), upper cylinder body (2) is provided with steam inlet pipe (3), lower cylinder body is provided with extraction steam pipe (4), (5) and two exhaust steam pipes (10), and the outer wall of lower cylinder body is provided with supporting rib (7) and supports platen (9), and present technique is welded with two stiffening ribs (1) on upper cylinder body (2) outer wall of existing turbine low pressure cylinder outer shell, by increasing the intensity of outer shell, prevented the outer shell distortion.Therefore low pressure (LP) cylinder long-play cylinder interior does not leak vapour, has kept cylinder to imitate not reducing, gross coal consumption rate do not increase.
