Description
Technical field
The present invention relates to hydroelectric facility field, particularly relate to a kind of integration formal dress mixed-flow wheel electromotor.
Background technology
Hydroturbine generator can be divided into impulse turbine and the big class of reaction turbine two by operation principle.Impact type water
The runner of turbine is rotated by the impact of current, and in work process, the pressure of current is constant, mainly the conversion of kinetic energy；Counterattack
The runner of the formula hydraulic turbine is rotated by the counteracting force of current in water, and in work process, the pressure of current all can have with kinetic energy
Change, but mainly pressure can conversion.
Impulse turbine, owing to its active wheel only part crosses water, part bucket stress, therefore such hydraulic turbine necessary flow
Less, relatively it is suitable for the generating place of low discharge high water head.Impulse turbine, can be divided into by the flow direction of current and cut the formula of hitting (again
Claim bucket-type) and tilt-impulse type two class, under the conditions of isometrical water wheels, the stress arm of force cutting the formula of hitting is relatively big relative to tilt-impulse type, but runs
Water wheels rotating speed is relatively small.
Reaction turbine can be divided into mixed-flow, axial-flow type, diagonal flow type and tubular.In Francis turbine, current
Radially into stator mechanism, axially flow out runner；In axial flow hydraulic turbine, current radially into stator, axially into and stream
Go out runner；In inclined flow turbine, current flow to runner radially into stator favouring the direction of a certain angle of main shaft,
Or flow to stator and runner to favour the direction of main shaft；In tubular turbine, current flow to stator and runner vertically.
Axial-flow type, tubular and inclined flow turbine also can be divided into by its structure determines paddle and rotary propeller type.The runner bucket determining paddle is
Fix；The runner bucket of rotary propeller type can be in operation and rotate, to adapt to the change of head and load around sharf.Currently make
With relatively broad mainly axial-flow type and Francis turbine.
The generally existing problem of the existing hydraulic turbine is: 1) impeller of the hydraulic turbine need to pass through with electromotor and excitation electromotor
Longer transmission shaft driven, and generally, the installation for the ease of power transmission shaft is changed, power transmission shaft junction can use flange
Connect, simultaneously in order to maintain power transmission shaft stable rotation, it is to avoid eccentric rotary, can arrange multiple in the junction of rotating shaft and middle part
Bearing, bearing increase the friction energy-dissipating that can strengthen in rotation process, bearing easily burns out because of temperature arrising caused by friction, and longer power transmission shaft
When eccentric rotary occurs, it is easily caused and electromotor is caused damage；2) electromotor and the exciter of existing hydroturbine generator exists
Work can produce substantial amounts of used heat (mainly by heavy current heat production in wire and bearing pivoting friction heat production), need to install specially
Heat radiation, cooling system, when heat radiation, cooling system go wrong, be easily caused movement, bearing burns out, even and if
Cooling system normally works down, and owing to stator and rotor are that inside and outside layer is distributed, the used heat of the rotor generation being positioned at internal layer need to pass through
Stator is transmitted to the external world with rotor every space gap layer, and little every the heat conduction rate of space gap layer, internal layer rotor is deposited with outer layer stator
In the bigger temperature difference, internal layer rotor easily burns；3), there are bigger current owing to utilizing at flow energy in the existing hydraulic turbine
Kinetic energy is remaining and frictional heat is lost, and the utilization rate of flow energy is relatively low, present stage, the relatively high stable of axial flow hydraulic turbine
Efficiency is only 90%；4) existing often group hydrogenerator is all the customization machine for different terrain, causes raw material, assembly, line
Material and parts can not be general, it is impossible to enough batch productions；5) due to the stator in hydrogenerator, rotor, salient pole, power transmission shaft
Needing to bear the stress of higher temperature or bigger Deng parts, the parts such as its stator, rotor, salient pole, power transmission shaft are to the strength of materials
Require height.Above-mentioned factor causes bigger input cost and production management's cost to the construction in power station, and power station produces production capacity
Relatively low, the small-sized available hydraulic power potentials of part is wasted.
Summary of the invention
The technical problem to be solved is: 1) in existing hydroturbine generator, power transmission shaft and bearing be due to stress relatively
Greatly, friction produce temperature higher, its loss is bigger；2) electromotor and the exciter of existing hydroturbine generator can produce greatly at work
The used heat of amount, needs to install special cooling system, and the cooling effect of its cooling system is not good enough, easily burn movement；3) existing
There is the relatively high stable efficiency of the hydraulic turbine only about 90%；4) existing hydrogenerator is all the customization machine for different terrain,
There is larger difference in volume, it is impossible to enough batch productions；5) parts pair such as the stator in hydrogenerator, rotor, salient pole, power transmission shaft
The strength of materials requires height.
