Abstract
The utility model relates to a through type cooling through -flow ventilation system of hydrogenerator, in the through -flow unit from the air outlet come out hot -blast through the assembly of induced air board, middle ring, introduce air cooler with middle ring deep bead and cool down, the cold air after the cooling passes through the ventilating duct and is inhaleed the generator rotor support by skew wind stream machine, deep bead, spider form the structure of keeping out the wind with the rotor deep bead, let the inside circulation system with an air of cooling channel formation of generator.
Description
Technical field:
The utility model relates to one and is applicable to through type cooling axial-flow hydrogenerator ventilating system.
Background technology:
Axial-flow hydrogenerator ventilating system is in the past the open installation aerial cooler that is used in the side of ventilating duct, the wind part importing rotor field spider into by diagonal flow fan during unit operation is the hot blast from the inner inspiration of unit, and a part is the wind from aerial cooler from outside inspiration.Cause hot blast just not import unit into by the cooling that aerial cooler is enough, overall ventilating system is by two air inlet air intakes, does not form the ventilating and cooling circulation of opposing seal, greatly reduces the cooling effectiveness of ventilating system.
Summary of the invention:
The purpose of this utility model is by inventing novel tubular-Francis turbine ventilating system, ensure that the sealing of ventilation improves the cooling effectiveness of ventilating system.The technical solution of the utility model is: a kind of through type cooling axial-flow hydrogenerator ventilating system, by aerial cooler (1), adapter ring (2), ventilating duct (3), skew wind stream machine (4), connecting plate (5), induced draft plate assembling (6), deep bead (7), adapter ring deep bead (8) and rotor deep bead (9) assembly, induced draft plate assembling (6), adapter ring (2), with adapter ring deep bead (8), conjunction is assembled together formation air-inducing passage, aerial cooler (1) is fixed to conjunction on adapter ring deep bead (8), hot blast carries out Air flow by aerial cooler (1), ventilating duct (3) is joined attaching together with aerial cooler (1) and skew wind stream machine (4), connecting plate (5) connects adapter ring (2) and skew wind stream machine (4), cold air is drawn into unit by skew wind stream machine (4), rotor deep bead (9) is fixed on adapter ring (2), deep bead (7) and rotor deep bead (9) form wind shielding structure, guarantee that cold air is last to induced draft plate assembling (6) after heating up from rotor to stator again.
Technique effect:
Novel tubular-Francis turbine ventilation unit, from air outlet hot blast out by induced draft plate assembling, adapter ring, be incorporated into aerial cooler with adapter ring deep bead in tubular-Francis turbine, by the heat-exchange capacity cooling-air of aerial cooler, generator rotor support is drawn into by skew wind stream machine, deep bead and rotor deep bead form wind shielding structure, allow generator and cooling duct form an airtight ventilating and cooling circulatory system.And the version of the two air inlet of unit in the past, be that the air of outside is mixed into hot blast in the middle of unit circulation by aerial cooler cooling, thus reach the object of ventilating and cooling.But because air cooler air inlet blast is higher than unit hot air inlet blast, the air quantity of hot blast can be caused higher than cooling air quantity, and aerial cooler does not embody enough effects, air cooler device heat transfer surplus is higher than measured data, and ventilating and cooling effect is not ideal enough.If in the middle of have cooler to break down, whole ventilation unit cannot meet cooling effect, and unit cannot stable operation.And novel ventilation unit not only by the hot blast of unit inside by aerial cooler all carry out heat exchange cooling be drawn into unit again, and contrast through actual measurement and calculated data, heat transfer surplus can reach more than 40%, if when air cooler exists fault in the middle of unit operation, can realize pulling down an aerial cooler and ensure stable operation of unit.
