Description

A kind of horizontal integrated anti-dress inclined beating type hydro-turbo generator and work method thereof

Technical field

The present invention relates to hydroelectric facility field, particularly relate to horizontal integrated anti-dress inclined beating type hydro-turbo generator and acting thereof Method.

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.

Inclined-jet turbine, owing to its vane stress is less relative to the vane stress of tangential wheel, the material to blade Matter and manufacturing process require relatively low and stable, noise is little, overall cost performance is higher, deeply by domestic and international small hydropower station enterprise Hobby.

But, the problem existing for existing inclined-jet turbine is: the 1) impeller of the hydraulic turbine and electromotor and excitation electricity Machine need to be by longer transmission shaft driven, and generally, the installation for the ease of power transmission shaft is changed, the meeting of power transmission shaft junction Use Flange joint, simultaneously in order to maintain power transmission shaft stable rotation, it is to avoid eccentric, can arrange in the junction of rotating shaft and middle part The most easily there is eccentric rotary in multiple bearings, this frame mode very consumptive material, and rotating shaft, be easily caused and electromotor is caused damage Lose；2) electromotor and the exciter of existing hydroturbine generator can produce substantial amounts of used heat at work (mainly by strong in wire Electric current produces), need to install special heat radiation, cooling system, when heat radiation, cooling system go wrong, be easily caused movement Burn out；3) generating efficiency of existing inclined-jet turbine is generally the most on the low side, the ideal efficiency wherein done only 80% to 84%；4) existing often group hydrogenerator is all the customization machine for different terrain, causes raw material, assembly, wire rod and zero Part can not be general, it is impossible to enough batch productions.

Due to above-mentioned factor, in power plant construction, Power Plant Design is more complicated, infrastructure project amount is relatively big, equipment conveying, installation Relatively costly；And the parts such as its stator, rotor, salient pole, power transmission shaft require height to the strength of materials；The problems referred to above are to small hydropower station Building and cause bigger input cost and production management's cost, and production capacity is less, the small-sized available hydraulic power potentials of part is unrestrained Take.

Additionally, the mode of work-doing of existing inclined-jet turbine is all: nozzle to be perpendicular to the radial manner of turbine blade, There is certain inclination angle with the inletpiston of folding shape blade in the high-velocity flow of nozzle, high-velocity flow enters along inletpiston, and flows 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, it flows out Current complementary energy relatively big, 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 On the low side.
