Description

Logical formal dress inclined beating type hydro-turbo generator and work method thereof during one is horizontal
Technical field
The present invention relates to hydroelectric facility field, particularly relate to a kind of horizontal in logical formal dress inclined beating 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.
Inclined-jet turbine, owing to its vane stress is less relative to the vane stress of tangential wheel, the material of blade and manufacturing process are required relatively low and stable, noise is little, overall cost performance is higher, is deeply liked by domestic and international small hydropower station enterprise.
But, problem existing for existing inclined-jet 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) existing inclined-jet turbine, remaining owing to there is bigger water flow dynamic energy in water flow dynamic energy utilization, the utilization rate of water flow dynamic energy is relatively low, present stage, and the ideal efficiency done in inclined-jet turbine is only 80% to 84%；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.
In addition, the mode of work-doing of existing inclined-jet turbine is all: nozzle is perpendicular to the radial manner of turbine blade, certain inclination angle is there is in the high-velocity flow of nozzle with the inletpiston of folding shape blade, high-velocity flow enters along inletpiston, and flow through the folding shape face of blade, being delivered on blade by its kinetic energy, last current go out from water outlet surface current；This kind of mode of work-doing, its current complementary energy flowed out is relatively big, and water flow dynamic energy transformation efficiency is on the low side；And kinetic energy loss is relatively big in the transmission process of its kinetic energy, generating efficiency is on the low side.
Summary of the invention
The technical problem to be solved is: 1) in existing hydroturbine generator, power transmission shaft and bearing are owing to stress is relatively big, friction product temperature is higher, and its loss is bigger；2) electromotor and the exciter of existing hydroturbine generator can produce substantial amounts of used heat at work, needs to install special cooling system, and the cooling effect of its cooling system is not good enough, easily burn movement；3) efficiency of existing inclined-jet turbine is only 80% to 84%, the most on the low side；4) existing hydrogenerator is all the customization machine for different terrain, and volume exists larger difference, it is impossible to enough batch productions；5) parts such as the stator in hydrogenerator, rotor, salient pole, power transmission shaft require height to the strength of materials.
