amended April 30, 1928; 8'70 0. G. 757) 4 Claims.
The invention describedherein may be manufacturedand used by or forthe Government for governmental purposes, withoutpayment tome of any royalty thereon.
This invention relates generally to hydroelectric power units but more I particularly to an improved type of water turbine and'means forcontrollingthe same;
One object of the invention is toprovide a turbine in Whichhydraulic thrust is eliminated by the compensation of pressures upon the runner blades.
Another object of the invention is to provide a turbine in which the diameter of the rotors may be reduced and consequently the weight and size of its casing without loss of power and efficiency.
Another object of the invention is to effect greater efl'iciency, economy in cost of construction, and space reduction, stability, ease of erection, and reduction of upkeep for turbine power units.
With the foregoing and other objects'in view, which will be apparent as the description proceeds, theinvention resides in the construction and arrangement of parts as hereinafter de-- scribed and claimed, itbeing understood that changes can be made within the scope of what is claimed, without departing. from the spirit of theinvention.
Referring to the figures in which like parts are designated by similar reference characters:
Figure 1 is a top planpartially sectionized view of the improved turbine equipped with double runners mounted on vertical shafts;
Figure 2 is a partially sectionized end elevation of the improved turbine equipped with double runners mounted on vertical shafts, the section being taken on the line 2-2 of Figure 1;
Figure 3 is a partially sectionized side elevation of the improved turbine equipped with double runners mounted on vertical shafts, the section being taken on the line 3-3 of Figure'l;
Figure 4 is a sectionized plan view showing the transmissionassembly,the section being taken on the lined-4 of Figure 2.
Briefly stated, the power apparatus described herein comprises a turbine iniwhich the runners are constructed with a central hub having blades with opposite stream deflecting surfaces mounted on either side thereof.
The hub is adapted to divide the impelling stream into two sections and the opposite reaction of ,the blade surfaces functions to eliminate hydraiili'c thrust on the runner shaft.
The turbine may be constructed with either double or single runners mounted on either horizontal or vertical shafts, and the impelling stream may be controlled by either a pivoted gate mounted within the draft tube, or by slidably movable gates mounted within the throat of the turbine. In either construction the impelling stream is controlled by means adapted to vary the quantity of flow through the runner channels.
Referring to Figure 1, the numeral It indicates the concrete foundation which is providedwith a hollow interior adapted to contain the casing H of the double or twin runner turbine. The casing H which surrounds each of the runners l2 and l2 and converges to a single circular entrance opening [3' isprovided with a flange M to which=is-attached the flange [5 of entrance tube The casing l I includes oppositely spiraled walls I1 and Ill forming two spiral supply scrolls defining channels [8 and I8 which are elliptical in cross-section and of progressively decreasing cross-sectional area and open between walledges [9- on their inner surfaces about dual runners E2 and l2. Wall edges I9 and [9' are themselves bearingsurfaces for the runner rings Zil and 2t which will be more fully described below. As viewed along the common center plane shown in Fig. l, the supply scrolls are attached at their larger ends to the supply tube or inlet conduit liiby which they are fed and are initially divergent and then spiraled symmetrically toward each other about the runners l2 and [2. The inlet conduit it, as extended by scrolls I1 and I1", is in effect a channel divided centrally by walls 25 and 2! into channel branches l8 and i8 defined by the scrolls. Scrolls IT and Il include fixed guide vanes I26 positioned between the walls of the scroll and across the opening between bearing surfaces It; These guide vanes l2t serveto deflect the fluid flow tangentially of the runners I 2 and I2 as that flow leaves the scrolls. The path of the actuating fluid of the turbineis through inlet conduit It, then equally divided between the inlet channel branches IS, iii of the two scrolls, across guide vanes 129, through the openings between walls or bearing surfaces. 59, through the runners l2 and I2 into delivery chambers or outlet channel branches and thence into a common outlet conduit 22, 32'. The delivery chambers or outlet channel branches are also defined by casing ll contiguous to the supply scrolls and generally in planes parallel to the common center plane of the scrolls.
Runners: l2 and 1-2 are identical and include runner shafts 33 and 39' journaled in bearings 31, 31', 38 and 38' in casing II and extending substantially normal to the common center plane of the supply scrolls and centered in the annular passageways formed by the annular bearing surfaces I9 on the inner sides of the scrolls.
To the flange 23 is attached a specially constructed valve casing or elbow 24 which is comprised of upper and lower sections 25 and 26, respectively, provided with flanges 21, 28, 29 and 33. The sections 25 and 26 are united by bolting together the flanges 28 and 29. The elbow 24 is bolted to the flange 23 of the casing H and to a flange 3| of a tubular outlet section 32 which is formed as the frustum of a cone and is mounted within the concrete foundation at the inner end of the conically shaped outlet channel 33.
The casing H as shown in Figures 2 and 3 is provided with circular openings 34 and 34 above the location of the runners l2 and [2. These openings are closed by circular cover plates 35 and 35 which are provided with flanges 36 and 35 and have centrally positioned shaft bearings 31 and 37. The cover plates 35 and 35' are bolted to the casing and may be removed when it is necessary to provide access to the runners or to remove the same. The bottom of the casing is provided with footstep bearings 38 and 38' beneath the bearings 3'! and 31 in the cover plates 35 and 35. On these footstep bearings 38 and 38 are mounted the runner shafts 39 and 39 on which are keyed the runners l2 and 12. The runners l2 and I2 include fusiform hubs 89 which taper symmetrically from enlarged central portions to the narrow ends and which are keyed on runner shafts 39 and 39'. The runners also include elongated symmetrical blades 56 mounted on the hubs 89 radially thereof with their major dimensions extending along the runner shafts, and runner rings surrounding and fixed to the exteriors of the blades between the enlarged center portion of the hubs and the ends of the blades. The runners are so positioned in the annular passageways that the enlarged center portions of the hubs equally divide the flow from the supply scrolls and so that the blades extend into both of the delivery chambers or outlet channel branches at each runner. Runner rings 23 are grooved exteriorly on the surfaces which bear against bearing surfaces l9 as shown in Figs. 2 and 3. These grooves permit the contacting bearing surfaces l9 and at 20 and 23 to be relatively extensive to stabilize the runners and at the same time to have a minimum amount of friction. The presence of runner rings 20 and both increase the strength of the runners and compel all fluid flow to pass through the runners and between the blades thereof so as to prevent power losses which would result if part of the flow were permitted to by-pass the runners.
The elbow which comprises sections 25 and 25, as shown in Figures 2 and 3, is provided with split bearings 50 and 52 formed at the juncture of their central flanges 28 and 29, as shown in Figures 2 and 3. These bearings support a shaft 42 to which is attached an arcuately shaped valve gate 43 adapted to be moved out of a bulged portion 44 of the elbow 24 into the path of the outgoing stream or vice versa, by the rotation of chain operated sprocket wheels 15 and 45 attached to the ends of the shaft 42.
The runner shafts 39 and 39 project upwardly through the bearings 31 and 31' in the cover plates and 35, and to their upper ends are keyed the gears 46 and 46, as shown in Figures 2, 3 and 4. These gears and 48 mesh with pinions 41 and 41, one of which is keyed to the generator shaft 48 which projects through bearing 4| in the top or cover plate 50. The pinion 41' which functions as an idler is mounted on a pinion shaft 43 which projects downwardly from the top or cover plate 50 of the housing 5 I.
The gears 43 and 46' and pinions 41 and 41' are contained within the housing 5| formed on the top of the runner casing II by the rim 52 and the upper cover plate 55. The cover plate is provided with a bearing 4! for the generator shaft 48. The rim 52 is welded or otherwise attached to angles 54 and 54 which are bolted respectively to the top of the runner casing I l and to the cover plate 50.
The flow of water through the turbine, shown in Figures 1, 2 and 3, which is provided with the arcuately shaped valve gate 43 may be controlled automatically by the mechanism which is described in detail in pending application Serial No. 546,461, filed July 25, 1944, which issued into Patent No. 2,435,968 on February 17, 1948.
The turbine shown is equipped with runners having double sets of symmetrically formed blades which divide the impelling stream entering the throat of the turbine through the intake channel and deflect the resulting streams laterally into the outlet channels. The division and lateral deflection of the impelling stream prevents lateral thrusts on the runner shaft and thereby provides a smoothly rotating runner and consequently a turbine of high efiiciency which is substantially free from vibration.
