Description
Technical field
The present invention relates to hydroelectric facility field, particularly relate to a kind of suspension easy heat radiation tilt-impulse type siphonal lobe hydrogenerator 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 bias, multiple bearing can be set in the junction of rotating shaft and middle part, this frame mode very consumptive material, and eccentric rotary the most easily occurs in rotating shaft, 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 (mainly being produced by heavy current in wire) at work, need special heat radiation is installed, cooling system, work as heat radiation, when cooling system goes wrong, it is easily caused movement to burn 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) generating efficiency of existing inclined-jet turbine is the most on the low side, and the ideal efficiency wherein done 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.
