Abstract
The invention discloses an integrated shaft-extension tubular water-turbine generating set. The set comprises a base as well as a water turbine, a speed controller, a thrust bearing box and a generator which are located on the base, wherein the water turbine is provided with a rotating part; the speed controller is located on the rotating part; the thrust bearing box is located between the water turbine and the generator. Compared with the prior art, the set has the advantages that the arrangement form of an existing shaft-extension tubular set is changed, and all main parts of the set are mounted on one base, so that the structural arrangement is simple and clear, the comprehensive utilization rate of the set can be increased, and the generating capacity of the set can be increased; 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, and the construction period is shortened.
Description
Technical field
The present invention relates to a kind of integrated shaft extension axial-flow hydrogenerator group, belong to hydroelectric power field.
Background technique
Axle extend through flow type hydraulic turbine is a kind of of tubular-turbine generator group, has structure, arranges that succinctly factory building civilwork engineering quantity is less, and unit equipment transportation and erection weight are lighter, and construction and equipment are easy for installation.Select this type can the reduction of erection time, realize generating (comparing with axial flow unit) in advance.Both at home and abroad the relevant statistics in water power plant shows, adopts through-flow unit than same capability axial flow unit, can cost saving 10%-25%, increase annual electricity generating capacity 3%-5%, and there are obvious economic advantages.Shaft extension through-flow unit divides again front shaft extension and two kinds of forms of rear shaft extension.
At the shaft extension through-flow unit moving, have two kinds of device forms at present, be respectively two kinds of direct connection and speedups, runner diameter, generally more than 1 meter, for the less power station of unit power output, as 100KW, be not to be just applicable to very much, and its installation period is longer.
Summary of the invention
It is high that technical problem to be solved by this invention is to provide a kind of comprehensive utilization ratio, the integrated shaft extension axial-flow hydrogenerator group that generated energy is large.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of integrated shaft extension axial-flow hydrogenerator group, comprise base and be all positioned at water turbine, speed regulator, thrust box and the generator on base, described water turbine has rotatable parts, described speed regulator is positioned on described rotatable parts, and described thrust box is between described water turbine and generator.
Further, in described thrust box, be provided with coupling.
Further, described water turbine has main shaft, and described generator is connected with the main shaft of water turbine by coupling.
Further, described generator is provided with rotating shaft, and described thrust box and alternator shaft interconnect.
Further, described water turbine is axle extend through flow type hydraulic turbine.
Further, described water turbine comprises water feed apparatus, water distributor, runner envelope and the drainage means connecting successively.
Working principle: the water with certain drop is flow through to water turbine, and the runner of water turbine rotates, and the potential energy converting and energy of water is mechanical energy, and the water turbine of rotation drives generator operation by coupling, and mechanical energy is converted to electric energy the most at last.
Beneficial effect: than prior art, the present invention changes the setting type of current existing shaft extension through-flow unit, critical piece in unit is installed on a base, such structural configuration is not only simple and clear, and can also improve the comprehensive utilization ratio of unit, increase the generated energy of unit, complete equipment is assembled and is debugged in factory, directly shipping is installed to power station after the assay was approved, greatly reduced building site installation workload, also shortened construction period, in addition, when unit need to be safeguarded, shut water inlet and outlet valve, opening runner envelope can overhaul, if scene does not possess maintenance condition, the bolt of Ke Jiang inlet and unclamping with the bolt at ell place, water turbine integral body is hung to original position can be transported to overhaul shop or manufactory carries out large repairs, easy to maintenance, unit need to be reserved by original shaft extension through-flow unit form that 3-4 place lower margin props up pier foundation and change that only to need fixedly water turbine base be pourable the second stage of concrete into, saved investment, being particularly suitable for the power station that less (the unit power output 300KW following) runner diameter of unit power output is less than 700mm selects.
Accompanying drawing explanation
Fig. 1 is the plan view of integrated shaft extension axial-flow hydrogenerator 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, integrated shaft extension axial-flow hydrogenerator group of the present invention, comprise base 5 and be all positioned at the water turbine 1 on base 5, speed regulator 2, thrust box 3 and generator 4, water turbine 1 has rotatable parts, speed regulator 2 is positioned on the rotatable parts of water turbine 1, thrust box 3 is between water turbine 1 and generator 4, thrust box 3 is portion's external members of an assembling, there is bearing the inside, the axial hydraulic thrust that thrust box 3 produces when bearing unit operation, in thrust-bearing 3, be provided with coupling, generator 4 is connected with the main shaft of water turbine 1 by coupling, thrust box 3 is connected with the rotating shaft of generator 4, water turbine 1 is axle extend through flow type hydraulic turbine, this water turbine 1 comprises the water feed apparatus connecting successively, water distributor, runner envelope and drainage means.
Working principle: the water with certain drop is flow through to water turbine 1, and the runner of water turbine 1 rotates, and the potential energy converting and energy of water is mechanical energy, the water turbine 1 of rotation drives generator 4 runnings by coupling, and mechanical energy is converted to electric energy the most at last.
The integrated shaft extension axial-flow hydrogenerator group provided by the invention on probation in a certain power station:
Turbine parameter is made as:
Impeller diameter: 0.6m
Sucking-off is high :-1.5m
Rated head: 12m
Rated flow: 1.5m
3/ s
Rated speed: 750rpm
Runaway speed: 1350rpm
Nominal output: 160.7kw
Sense of rotation: be seen as clockwise direction toward downstream from upstream.
This unit is identical with the runner form of conventional axle extend through flow type unit, difference is to have used base, and water turbine, generator, thrust box are assembled on base, and in factory, assembly and adjustment is good, self-contained delivery, is guaranteeing to have shortened installation period when water can be fully used.
This station equipment is transported to behind building site, makes centering base, makes it in basic horizontal, the forward flange of unit is connected with the flange mouth of pre-buried good inlet and outlet channel in advance simultaneously, then pour into a mould the second stage of concrete, front and back only two weeks consuming time just drops into trial run, exerts oneself all better with traveling comfort.
In sum, this self-contained shaft extension axial-flow hydrogenerator group will have good promotional value and market adaptability.
