Abstract
The utility model relates to a kind of reaction turbine, comprises rotor main shaft, impeller, moving vane and nozzle; The central axis place of described impeller has axis hole, interspersed described rotor main shaft in the axis hole of described impeller; Equidistant on the wheel limit of described impeller described moving vane is set, it is characterized in that, described moving vane is provided with described nozzle.The beneficial effects of the utility model are: the heat energy that can utilize high pressure steam to the full extent.
Description
Technical field
The utility model belongs to turbine power and to learn a skill field, is specifically related to a kind of reaction turbine.
Background technique
Steam turbine is the worm-gear type machinery thermal power transfer of steam being become mechanical energy.In steam turbine, steam expands in nozzle, and pressure reduces, and speed increases, and thermal energy is kinetic energy.But steam turbine of the prior art is impulse steam turbine or reaction turbine.Impulse steam turbine refers to that steam mainly expands in nozzle, not reflation or expand seldom in moving vane, and mainly changes flow direction; Reaction turbine refers to steam not only in nozzle, and in moving vane, also carry out the steam turbine that expands, the moving vane of reaction turbine is not only subject to the active force produced due to shock of steamy flow, and be subject to steam expand in moving vane accelerate and produce active force.
Reaction turbine of the prior art also has the structural principle of impulse, can not realize utilizing heat energy better.
Model utility content
In order to solve the technological deficiency that prior art exists, the utility model provides a kind of reaction turbine, the structure of this reaction turbine has abandoned the structure of impulse steam turbine completely, is set directly at by nozzle on moving vane, and this kind of setting can be energy-conservation to the full extent.
The technological scheme that the utility model adopts is: a kind of reaction turbine, comprises rotor main shaft, impeller, moving vane and nozzle; The central axis place of described impeller has axis hole, interspersed described rotor main shaft in the axis hole of described impeller; Equidistant on the wheel limit of described impeller described moving vane is set, it is characterized in that, described moving vane is provided with described nozzle.
Preferred technological scheme is that be provided with the duct of high pressure steam circulation in described rotor main shaft, impeller and moving vane, high pressure steam enters described nozzle after flowing through described rotor main shaft, impeller, moving vane successively further.
Preferred technological scheme is further, the adjustable angle of described nozzle on described moving vane.
Preferred technological scheme also has further, and all described nozzles are all arranged on described moving vane by angle demodulator.
Further preferred technological scheme is, described angle demodulator comprises nozzle bracket and bead wraps device, the lower end of described nozzle bracket is location bead, and described location bead is arranged on described bead and wraps in device, and described bead is wrapped device and is arranged on described moving vane.
The beneficial effects of the utility model are: nozzle is set directly on moving vane, by whole the spraying on nozzle of mechanical energy that thermal energy comes, the moving vane on the one hand nozzle place obtain the momentum of reactionary style and the mass transitions in conjunction with impeller is kinetic energy; On the other hand, the nozzle on a upper moving vane also has impulsion power to next moving vane, thus next moving vane also correspondingly obtains kinetic energy.
Nozzle is arranged on moving vane by angle demodulator, under nozzle arranges inappropriate situation, according to actual conditions, can suitably regulate the direction of nozzle, to reach reasonable disposition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-rotor main shaft; 2-impeller; 3-moving vane; 4-nozzle.
Embodiment
As shown in Figure 1, the utility model provides a kind of reaction turbine, comprises rotor main shaft 1, impeller 2, moving vane 3 and nozzle 4; The central axis place of impeller 2 has axis hole, interspersed rotor main shaft 1 in the axis hole of impeller 2; Equidistant on the wheel limit of impeller 2 moving vane 3 is set, moving vane 3 is provided with nozzle 4.
Further preferred embodiment is, is provided with the duct of high pressure steam circulation in rotor main shaft 1, impeller 2 and moving vane 3, and high pressure steam enters nozzle 4 after flowing through rotor main shaft 1, impeller 2, moving vane 3 successively.
Further preferred embodiment is, the adjustable angle of nozzle 4 on moving vane 3.
Further preferred embodiment also has, and all nozzles 4 are all arranged on moving vane 3 by angle demodulator.
Further preferred embodiment, angle demodulator comprises nozzle bracket and bead wraps device, and the lower end of nozzle bracket is location bead, and location bead is arranged on bead and wraps in device, and bead is wrapped device and is arranged on moving vane 3.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection domain of the present utility model.
