Abstract
The utility model relates to a rubber sealing washer for a generator water spinning box, which is composed of two pieces of washers (5 and 6). The washers are trumpet-shaped, one end of each washer is a running-in part (3 or 4) whose inner surface is provided with annular bulges (7), the outside of each washer is connected with a mounting part (1 or 2) which is provided with small holes (9), the running-in parts (3 and 4) are combined with the mounting parts (1 and 2) as integration, and included angles are formed by the running-in parts and the mounting parts. The rubber sealing washer (5 and 6) has the advantages of long service life, not easy breakage and good sealing performance.
Description
The utility model belongs to rubber gasket, relates in particular to generator water spinning box rubber gasket.
The large-scale turbo-generator with inner water-cooled stator and rotor group of homemade QFS-125, what generator amature backwater water spinning box sealing gasket adopted is home built ordinary flat rubber gasket, it is that two of inclined-plane form by the faying surface that cooperatively interacts, be horn-like, one end is the break-in part of Taper Pipe shape, wherein being distributed with and the water spinning box end cap screwed hole mounting portion of installing hole one to one of the big garden of break-in part end external flange plate-like, mounting portion and break-in partly are an integral body, and plane, mounting portion and break-in part bus have an angle.Rubber gasket be under 3000 rev/mins of high rotating speeds to the sealing of water, the generator water spinning box rubber gasket that is in operation is easily broken, easily leaks, fragment enters the electric generator inner cooling water system, stop up generator unit stator easily, rotor coil causes the generator accident of burning.
The purpose of this utility model provides a kind of can increasing the service life, and is difficult for fragmentation, the generator water spinning box rubber gasket of good seal performance.
The purpose of this utility model realizes by following measure: rubber gasket is horn-like, one end is the break-in part that the inner face of Taper Pipe shape is distributed with annular protrusion, wherein being distributed with and the water spinning box end cap screwed hole mounting portion of installing hole one to one of the big garden of break-in part end external flange plate-like, mounting portion and break-in partly are an integral body, plane, mounting portion and break-in part bus have an angle, for ease of installation and maintenance, rubber gasket is that two of inclined-plane form by the faying surface that cooperatively interacts, when making it to be installed on the water spinning box, the annular protrusion of rubber gasket inner face can be held generator shaft tightly, and two of rubber gasket seamlessly can form an integral body again.
The utility model is owing to the break-in part inner face at former rubber gasket increases annular protrusion, make rubber gasket and motor shaft contact area reduce, the friction of rubber gasket and generator shaft when having reduced the generator shaft rotation, therefore the utility model is durable in use, is difficult for fragmentation, has eliminated the electric generator inner cooling water pollution, the water spinning box drainage, solved fragment to generator unit stator, the rotor coil blockage problem has avoided generator to burn and the generation of near accident effectively.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of vertical view of the present utility model
Fig. 2 is along the cutaway view of A-A direction among Fig. 1
Fig. 3 is 1 a partial enlarged drawing among Fig. 2
Fig. 4 is an installation diagram of the present utility model
Fig. 5 is a sectional side elevation of the present utility model among the embodiment 1
Among the figure: 1, mounting portion 2, mounting portion 3, break-in part 4, break-in part 5, rubber gasket 6, rubber gasket 7, annular protrusion 8, hex bolts 9, installing hole 10, water spinning box end cap 11, arc 12, drag washer
In embodiment shown in Figure 51, rubber gasket 6 is horn-like, one end is the break-in part 4 that the inner face of Taper Pipe shape is distributed with 2 circle annular protrusions, wherein being distributed with and the water spinning box end cap screwed hole mounting portion 2 of installing hole 9 one to one of break-in part 4 big garden end external flange plate-likes, mounting portion 2 is an integral body with break-in part 4, and the bus of the plane of mounting portion 2 and break-in part 4 has a angle 40 °; Rubber gasket 6 is that two of inclined-plane form by the faying surface that cooperatively interacts, when making it to install on the water spinning box, rubber gasket 6 can be held generator shaft tightly, two of rubber gasket 6 is the seamless complete integral body that can form again, owing to increase the contact area that annular protrusion can significantly reduce rubber gasket and generator shaft, friction when reducing the generator shaft rotation plays the effect that prolongs the rubber seal pad life.
Rubber gasket is the rubber gasket that the one-time formed nitrile rubber of mould machining is made in embodiment shown in Figure 12, it forms an integral body by two that cooperatively interact, faying surface is the inclined-plane, rubber gasket 5 can drag tight generator shaft when making it to be installed on the generator water spinning box, and is seamless between two of rubber gasket 5.Rubber gasket 5 is horn-like, one end is the break-in part 3 that the inner face of Taper Pipe shape is distributed with 3 circle annular protrusions 7, wherein being distributed with and the water spinning box end cap screwed hole mounting portion 1 of installing hole 9 one to one of break-in part 3 big garden end external flange plate-likes, mounting portion 1 is an integral body with break-in part 3, and the angle of the bus of the plane of mounting portion 1 and break-in part 3 is 30 ° (in addition referring to Fig. 2, Fig. 3).Because it is the one-time formed rubber gasket of mould machining that the rubber flat plate pad is made in change in the past by hand, has reduced labour intensity, has improved efficiency, owing to use nitrile rubber to increase elasticity, resistance to wear and the ageing resistance of rubber gasket; Because the angle of the bus of the plane, mounting portion of design rubber gasket and break-in part is 30 °, reduced to install the pulling force of back to rubber gasket, the elasticity and the intensity of rubber gasket have been improved, guarantee excellent sealing performance, owing to increase by 3 circle annular protrusions, make rubber gasket 5 longer than the life-span of the rubber gasket among the embodiment 16, better to the sealing property of water.
Fig. 4 is the installation diagram of the utility model in QFS-125 generator water spinning box, what use among the figure is rubber gasket 5 among the embodiment 2, mounting portion 1 is close to water spinning box end cap 10 and is made the aperture 9 in the mounting portion 1 corresponding one by one with screwed hole in the water spinning box end cap 10, is pressing with arc 11 outside, fixing with drag washer 12 and hex bolts 8.
