Abstract
The invention discloses an integrated bulb type water-turbine generating set. The set comprises a water turbine, a generator and an accelerator, wherein the generator is provided with a spindle, the water turbine is provided with a rotating wheel, the spindle of the generator is horizontally connected with the rotating wheel of the water turbine, and the accelerator is arranged between the generator and the water turbine. The accelerator is applied to the bulb type water-turbine generating set, so that a large-pole-number generator is omitted; the water turbine is lower in rotating speed, and the rotating speed is increased by the accelerator to reach the rotating speed of the generator, so that reduction of the equipment input and arrangement of the set are facilitated; the whole set is assembled and commissioned in a factory and directly transferred to a power station for installation after being checked to be qualified, so that the construction site installation workload is reduced.
Description
Technical field
The present invention relates to a kind of self-contained bulb water turbine group, belong to hydroelectric power field.
Background technique
Bulb water turbine group is the tubular turbine that a kind of efficiency is high, inflow-rate of water turbine is large, and generator is positioned at the light bulb head of influent side, and its performance index, degree of normality are all higher, has been widely used in the world, domestic water power station.This kind of type, through the development of decades, perfect, occupies certain share in the hydroelectric power market of low water head, and single-machine capacity and runner diameter all have increasing trend.Bulb water turbine group is mainly comprised of bulb type generator and bulb turbine, shares a main shaft, adopts rigid joint (being also direct connection).
Bulb water turbine group in the market exists following problem and shortcoming: because the applicable head of bulb water turbine group is not high, conventionally below 15 meters, if single-machine capacity has requirement, and rated head not high (as 2-4 rice), certainly will to adopt the motor of large number of poles, both be unfavorable for tissue production, price also can be higher, and the income of investment just has impact like this; Bulb water turbine group is assembled conventionally on-site, easily make to install effect and do not reach required requirement, and the quality of installation quality directly affects the operation of unit.
Summary of the invention
Technical problem to be solved by this invention is to provide the self-contained bulb water turbine group that a kind of efficiency is high, generated energy is large.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A self-contained bulb water turbine group, comprises water turbine, generator and speed increaser, and described generator has main shaft, and described water turbine has runner, and generator shaft and rotary wheel of water turbine level connection joint are provided with speed increaser between described generator and water turbine.
Further, described water turbine is half tubular turbine.
Further, the rotating speed of described water turbine is 284.37rpm, and the rotating speed of described generator is 1000rpm, and the speed ratio of described speed increaser is 3.517, and input power is 274KW.
Further, also comprise flume, water distributor and draft tube.
Working principle: water enters hydraulic generator unit from the head of bulb-style, and the water with certain drop flows through water turbine, the runner of water turbine rotates, the potential energy converting and energy of water is mechanical energy, by the speed change of speed increaser, drive generator operation generating, mechanical energy is converted to electric energy.
Beneficial effect: than prior art, the present invention is used for bulb water turbine group by speed increaser, avoided adopting the generator of large number of poles, rotational speed of water turbine is lower, by speed increaser, rotating speed is improved, and reaches the rotating speed of generator, be conducive to reduce equipment investment and be convenient to unit and arrange, complete equipment is assembled and is debugged in factory, and directly shipping is installed to power station after the assay was approved, reduces building site installation workload.In addition, novel structure of the present invention, easy to maintenance, when unit need to be safeguarded, unclamp the connecting bolt of import and export, unit can be hung between maintenance and safeguard, if conventional a small amount of maintenance detects, can the enter hole from shell enter into runner inside, open capping and can check easily and change quick-wear part, it has the higher market competitiveness, is particularly suitable for extra low head, the less power station (unit power output 300KW is following) of unit power output.
Accompanying drawing explanation
Fig. 1 is the plan view of the self-contained bulb water turbine group of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, self-contained bulb water turbine group of the present invention, comprise water turbine 1, generator 2 and speed increaser 3, generator 2 has main shaft, water turbine 1 has runner, and generator 2 main shafts and water turbine 1 runner level connection joint are provided with speed increaser 3 between described generator 2 and water turbine 1, water turbine 1 is half tubular turbine, and the present invention also comprises flume, water distributor and draft tube.
Working principle: water enters hydraulic generator unit from the head of bulb-style, the water with certain drop flows through water turbine 1, and the runner of water turbine 1 rotates, the potential energy converting and energy of water is mechanical energy, by the speed change of speed increaser 3, drive generator 2 running generatings, mechanical energy is converted to electric energy.
The self-contained bulb water turbine group provided by the invention on probation in a certain power station:
3.5 meters, this Power Plant Design head, unit 250KW, rotational speed of water turbine is made as: 284.37rpm; Generator speed is made as: 1000rpm; By gear speeder, carry out speedup, speed increaser parameter is: speed ratio I=1000/284.37=3.517, input power 274KW.This unit is identical with the runner form of conventional bulb unit, and difference is to have used speed increaser to carry out speed change and drives generator generating, and this unit is self-contained delivery, has not only reduced equipment investment but also saved installation period.
This equipment is transported to behind building site, and the level of adjusting unit is connected the front and back flange of unit simultaneously with the flange mouth of pre-buried good inlet and outlet channel in advance, and front and back only two weeks consuming time just drops into trial run, exert oneself and traveling comfort all better.
In sum, the self-contained bulb water turbine group of the present invention compared with prior art prepares shipping again to building site by unit integral installation in factory, greatly reduced the workload of installing, when shortening installation period, also reduced investment, and the present invention is used for bulb water turbine group by speed increaser, avoided adopting the generator of large number of poles, effectively reduce equipment investment cost, easy to maintenance, there is good promotional value and market adaptability, be particularly suitable for extra low head, the less power station (unit power output 300KW is following) of unit power output.
