Abstract
The utility model discloses a seal structure of a generator hydrogen cooler, wherein a first flange, a second flange and a third flange are arranged at the front and rear water chambers of the cooler; a seal gasket is arranged between the flanges; grooves are formed on the flange surfaces of the first flange, the second flange and the third flange; convex ribs are arranged on the seal gaskets; and the convex ribs are embedded in the grooves. By the seal structure of the generator hydrogen cooler, the flange surfaces of the front and the rear water chambers are sealed very well and more reliably, so that the sealing reliability is improved. Furthermore, as fluororubber has better corrosion resistance, and the service life of the seal gaskets is prolonged.
Description
Technical field:
The utility model relates to a kind of sealing configuration, relates in particular to a kind of sealing structure of hydrogen cooler of generator.
Background technique:
Hydrogen cooler of generator effect: the heat that the loss that stator and rotor winding, stator iron core, machine operation produced during the cooled electric generator operation converts to; Prevent that generator each several part temperature from raising, running temperature is too high can be quickened insulation ag(e)ing and shorten insulation life.But existing hydrogen cooler of generator is the hydroecium flange connections in front and back, uses common liner to seal, and in use, because vibrations and factors such as liner is aging tend to produce leakage phenomenon, brings hidden danger to the normal operation of generator.
The model utility content:
In order to address the above problem, the utility model provides a kind of sealing structure of hydrogen cooler of generator.
The technological scheme of the utility model is: sealing structure of hydrogen cooler of generator; At hydroecium place, the front and back of cooler first flange, second flange and the 3rd flange are arranged; Be lined with sealing gasket between flange, it is characterized in that, the flanged surface of said first flange, second flange and the 3rd flange is provided with groove; Said sealing gasket is provided with convex tendon, and said convex tendon embeds groove.
The top and bottom of said sealing gasket are provided with convex tendon.
Said sealing gasket adopts the fluorine rubber material.
The beneficial effect of the utility model is: the flanged surface of hydroecium had obtained sealing better more reliably before and after the utility model made, and had improved the reliability of sealing.In addition, fluorine rubber has better decay resistance, has prolonged the working life of sealing gasket.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of sealing gasket among Fig. 1.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, shown in 2; Sealing structure of hydrogen cooler of generator; First flange 100, second flange 200 and the 3rd flange 300 are arranged at hydroecium place, the front and back of cooler, and the flanged surface that is lined with sealing gasket 400, the first flanges 100, second flange 200 and the 3rd flange 300 between flange is provided with groove 500; Sealing gasket 400 is provided with convex tendon 410, and said convex tendon 410 embeds groove 500.The top and bottom of sealing gasket 400 are provided with convex tendon 410.Sealing gasket 400 adopts the fluorine rubber material.The flanged surface of hydroecium had obtained sealing better more reliably before and after the utility model made, and had improved the reliability of sealing.In addition, fluorine rubber has better decay resistance, has prolonged the working life of sealing gasket.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
