Abstract
The utility model discloses a water power generator sealing device which relates to a water power generator, in particular to a waterproof sealing device mainly for the water power generator on a water supply pipe network in a town. The utility model provides the water power generator sealing device which has great sealing performance, is secure and reliable to serve to the water supply pipe network in the town, a rotating sealing ring, a pressing bearing and a pressing ring are provided; the rotating sealing ring is sleeved on a rotor shaft of an original rotor and provided with an annular groove; the pressing bearing is arranged above the rotating sealing ring and installed on the rotor shaft of the original rotor; the pressing ring is pressed on the pressing bearing and is connected with a containing cavity of the original rotor.
Description
Technical field
The utility model relates to a kind of hydroelectric generator, especially relates to a kind of waterproof seal that is mainly used in the online hydroelectric generator of cities and towns running water pipe.
Background technology
Being mainly used in the online hydroelectric generator of cities and towns running water pipe is to utilize the direct drives impeller of pressurised stream, and impeller drives the rotating shaft of rotor and rotates, and rotating shaft drives rotor rotation, and the coil cutting magnetic line of stator produces electric current and generates electricity.Electric current is drawn the treated household electrical appliance that promptly can be applicable to.This hydroelectric generator is a kind of product of energy-conserving and environment-protective.But, because the current of impeller cavity easily leak from the rotating shaft of rotor, cause water to enter the cavity volume of rotor and stator, thereby cause that short circuit burns motor, have a strong impact on the useful life of hydroelectric generator.This is because the sealing device of rotating shaft is to adopt conventional rotating seal ring, conventional rotating seal ring is influenced by temperature, pressure etc. in the rotation with the rotating shaft of rotor, time one is long, easily cause distortion and aging, its intrinsic elasticity is weakened greatly, cause its sealing property to descend, the water that makes impeller cavity easily is leaked to the cavity volume of rotor and stator from the gap that the rotating shaft periphery of rotor produces.
Summary of the invention
The purpose of this utility model provides a kind of good seal performance, safe and reliable, is mainly used in the online hydroelectric generator sealing device of cities and towns running water pipe.
The utility model is provided with rotating seal ring, compresses bearing and pressure ring; Rotating seal ring is enclosed within the rotating shaft of former rotor, and rotating seal ring is provided with annular recess; Be provided with above rotating seal ring and compress bearing, compress in the rotating shaft that bearing is installed in former rotor, pressure ring is pressed in and compresses on the bearing, and pressure ring is connected with the reservoir body of former rotor.
The annular recess of described rotating seal ring is a V-ring shape groove.
Described pressure ring is connected preferably, and employing is threaded with the reservoir body of former rotor.
Compare with the existing online hydroelectric generator sealing device of cities and towns running water pipe that is mainly used in, the utlity model has following outstanding advantage and effect:
Because rotating seal ring is provided with annular recess, cross section is M shape, and it has a kind of intrinsic radial dilatation elastic force, when its rotating shaft with rotor is rotated, adjustment capability is voluntarily arranged, can avoid the periphery of the rotating shaft of rotor to produce the gap, prevent that the water of impeller cavity is leaked to the cavity volume of rotor and stator.Compress bearing and pressure ring because be provided with again, the rotation pressure ring can be honoured rotating seal ring by compression axis and carry out axial pressure, thereby the moving and effective radial expansion force that keeps rotating seal ring of the end play string that can prevent rotating seal ring makes sealing effectiveness better, and reliability significantly improves.
