Accompanying drawing explanation
Fig. 1 is the structural representation of unified the embodiment of cooling system of this utility model bulb tubular turbine,
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
Detailed description of the invention
As depicted in figs. 1 and 2, the cooling system of bulb tubular turbine, including generating set main body, described unit master
Internal being provided with the motor being made up of out frame 1, stator 2 and rotor 3, the tail end of described generating set main body is provided with
Light bulb head 4, corresponding described light bulb head position is communicated with the motor vertical shaft 5 of described generating set main body, described stator
The shell of support is the double-tube structure with interlayer 11, is provided with copper fin in this interlayer.
The upstream side of described motor is provided with centrifugal fan 6 and air cooler 7, the number of described air cooler
Amount is for some, and circumference uniform distribution is in the upstream side of described out frame.The air-flow that described centrifugal fan produces passes through
The inside of logical described stator, side enters the interlayer of described double-tube structure the most downstream, and this air-flow is from this folder
The upstream side of layer out, finally passes sequentially through described air cooler and centrifugal fan, ultimately forms airtight
Circulation, it is achieved axial ventilation, sealing and circulating, forced air cooling.
Go out from blower fan as pressure source, the air of cooled electric generator at electromotor upstream side installing centrifugal fan
Mouth flows out, and axially into generator stator-rotator gap and magnetic pole interpolar, and a road flows to the downstream of electromotor,
Entering the interlayer of downstream band copper fin after cooling stator end bar, most of heat of unit passes through support
In wall and runner, river carries out heat exchange, and therefore inherently one efficiently for the out frame shell of band copper fin
Cooler.Air after supercooling from upstream side interlayer mouth out, enters air cooler and cools down further.
Such aeration structure form on the one hand aeration structure is simple, and calculating for ventilating provides accurate model.
On the other hand solving bulb tubular turbine routine ventilation cooling system because of narrow space, heat is all by air cooler
When taking away, air cooler is difficult to the limitation arranged.Therefore this ventilation cooling system is in limited space, reaches
Arrive preferable cooling effect, it is ensured that the safe and stable operation of unit.
Being additionally provided with water-cooling system in described generating set main body, described water-cooling system includes water pipe 8 and can be directly from stream
The water fetching device 9 of water intaking in road, described water fetching device is located at the top of described motor vertical shaft, entering of described water pipe
The mouth of a river all connects with described water fetching device with outlet, and the cooling water in described water pipe is from described air cooler
Pass through.The cooling water water intaking of air cooler is directly fetched water with water pump by vertical shaft outer flow passage, and it is standby to arrange a master one
Water supply pump, arrange filtration, flow, pressure-detecting device ensure cooling supply water safe and reliable.
The cooling water system used in this utility model directly runner from generating cabin is fetched water, cooling
The water filtration by water strainer, clean water enters water pump, flow indispensable on some pipelines and pressure inspection
Surveying instrument, cooling water enters air cooler, cools down, ventilation, the lubricating system of electromotor finally by heat
Water is immediately discharged in runner, and the water supply and sewage path the most once cooled down substantially reduces the length of pipeline so that
Cooling effect is highly efficient, and structure arranges simplerization.This structure is without from the upper water in power station simultaneously
Storehouse diversion, substantially increases the security reliability that power station flood control is passed the flood period.Unit is located at by the intake of this structure
In deflector, on the one hand the current to intake have the effect of current stabilization, ensure that intake is the most blocked, separately
On the one hand it is right due to upper pond rubbish floating object, pasture and water, testacean aquatics etc. to avoid during conventional water intaking
The blocking of cooling water supply line, further increases reliability and the effect of electromotor cooling of cooling water system
Really.
