Description

During one is horizontal, logical paperback turns oar axial flow type hydro-turbo generator and work method thereof
Technical field
The present invention relates to hydroelectric facility field, particularly relate to a kind of horizontal in logical paperback turn oar axial flow type hydro-turbo generator and work method thereof.
Background technology
Hydroturbine generator can be divided into impulse turbine and the big class of reaction turbine two by operation principle.The runner of impulse turbine is rotated by the impact of current, and in work process, the pressure of current is constant, mainly the conversion of kinetic energy；The runner of reaction turbine is rotated by the counteracting force of current in water, in work process current pressure can and kinetic energy all 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 is less, is relatively suitable for the generating place of low discharge high water head.Impulse turbine, can be divided into the formula of hitting of cutting (also known as bucket-type) and tilt-impulse type two class by the flow direction of current, and 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 it is relatively small to run water wheels rotating speed.
Reaction turbine can be divided into mixed-flow, axial-flow type, diagonal flow type and tubular.In Francis turbine, current, radially into water distributor, axially flow out runner；In axial flow hydraulic turbine, current radially into stator, axially into flow 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 fixing；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 used 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 be by longer transmission shaft driven with electromotor and excitation electromotor, and generally, installation for the ease of power transmission shaft is changed, power transmission shaft junction can use Flange joint, simultaneously in order to maintain power transmission shaft stable rotation, avoid eccentric rotary, multiple bearing can be set in the junction of rotating shaft and middle part, 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 is when there is eccentric rotary, it is easily caused and electromotor is caused damage；2) electromotor and the exciter of existing hydroturbine generator can produce substantial amounts of used heat at work (mainly by heavy current heat production in wire, and bearing pivoting friction heat production), need special heat radiation is installed, cooling system, work as heat radiation, when cooling system goes wrong, it is easily caused movement, bearing burns out, even if under cooling system normally works, owing to stator and rotor are interior, outer layer is distributed, it is positioned at used heat that the rotor of internal layer produces and need to be transmitted to the external world by stator and rotor every space gap layer, little every the heat conduction rate of space gap layer, the bigger temperature difference is there is in internal layer rotor with outer layer stator, internal layer rotor easily burns；3) the existing hydraulic turbine, owing to existing in flow energy utilization, bigger water flow dynamic energy is remaining and frictional heat is lost, and the utilization rate of flow energy is relatively low, present stage, and the relatively high stable efficiency of axial flow hydraulic turbine is only 90%；4) existing often group hydrogenerator is all the customization machine for different terrain, causes raw material, assembly, wire rod and the parts can not be general, it is impossible to enough batch productions；5) needing to bear the stress of higher temperature or bigger due to the parts such as the stator in hydrogenerator, rotor, salient pole, power transmission shaft, the parts such as its stator, rotor, salient pole, power transmission shaft require height to the strength of materials.Above-mentioned factor causes bigger input cost and production management's cost to the construction in power station, and power station production production capacity is relatively low, and the small-sized available hydraulic power potentials of part is wasted.
