Abstract
The utility model relates to a speed-increasing and flow-guiding device for water turbines. A flow-guiding member which is composed of a plurality of corresponding flow-guiding conical tubes is arranged between a water-guiding chamber and the rotating wheel chamber of the water turbine. The utility model has the advantages of reasonable structure, and convenient manufacture, causes the rotating speed of the water turbine to be increased in duplicate, reduces the structure and manufacture difficulties of the generator set of the water turbine, reduces the cost of the device, improves the efficiency of the water turbine, and is suitable for the development and the utilization of the scattered hydroelectric power resources.
Description
The utility model belongs to a kind of flow guide device of water turbine, particularly relates to a kind of speeding deflector that does not adopt the counterattack type water turbine of scroll casing type flume.
At present, in not adopting the counterattack type water turbine of scroll casing type flume, because only by being fixed on the pressure flow that wing fixed guide vane on the seat ring and movable guide vane enter rotary wheel of water turbine, kinetic energy that is had and rotation (circular rector) are very little, thereby the rotating speed that runner is formed is very low, caused water turbine and generator Structure huge, made difficulty, cost an arm and a leg.Seriously restricted the development and utilization of the hydroelectric resources of fragmentary dispersion.
The purpose of this utility model is to avoid the deficiency of above-mentioned counterattack type water turbine, and provide a kind of can making to have required kinetic energy and rotation (circular rector), thereby improve the speeding deflector of rotational speed of water turbine by fixed guide vane, movable guide vane or the pressure flow that directly enters rotary wheel of water turbine.
The purpose of this utility model can reach by following measure: the speeding deflector of this water turbine, comprise flume and turbine chamber, and between flume and turbine chamber, have the diversion component of forming by several corresponding water conservancy diversion Taper Pipes.
The water conservancy diversion Taper Pipe that constitutes diversion component can be formed by installing several diaphragms between interior aqueduct that can constitute awl tubular runner and the outer aqueduct.
The water conservancy diversion Taper Pipe that constitutes diversion component can also be the conical pipeline that tilts to install by same sense of rotation.
The global shape of diaphragm can also be spiral, and its surface configuration can also be a broken line shape.
This apparatus structure is reasonable, make simple, and the flow energy that will flow into runner with the hydraulic loss of minimum is converted to kinetic energy and rotation (circular rector), the rotating speed of water turbine is multiplied, the structure and the manufacture difficulty of hydraulic generator unit have not only been reduced, reduce equipment manufacturing cost, and improved the efficient of water turbine.This device extremely adapts to the fragmentary hydroelectric resources development and utilization that disperses.
Embodiment of the present utility model is provided by following accompanying drawing:
Fig. 1 is first embodiment of the present utility model: the structural representation of the speeding deflector that the installing diversion component is made up of several spirality water conservancy diversion Taper Pipes in the axial flow open-flume turbine.
Fig. 2 is second embodiment of the present utility model: the structural representation of the speeding deflector that the installing diversion component is made up of several conical pipelines that tilt to install by same sense of rotation in the axial flow open-flume turbine.
Fig. 3 is the 3rd embodiment of the present utility model: the installing diversion component is by the structural representation that installs the speeding deflector that several spirality diaphragms form in bulb through-flow turbine.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, in the waterexit end of flume (1) is affixed this water pipe (2) and outside aqueduct (3), constitute the cone barrel type runner, interior aqueduct (2) and outside install 5 spirality diaphragms (4) between the aqueduct (3), form the diversion component that combines by 5 spirality water conservancy diversion Taper Pipes (5).The other end of interior aqueduct (2) and outer aqueduct (3) is packed in the top of the interior ring (6) and the outer shroud (7) of seat ring respectively, is fixed with wing fixed guide vane (8) between interior ring (6) and the outer shroud (7).The affixed movable water distributor in the bottom of seat ring (9) installs runner envelope (10) between movable water distributor (9) and the draft tube (11).Interior ring (6) inside at seat ring installs guide bearing (14), and guide bearing (14) is equipped with main shaft (13), and the end that main shaft (13) is positioned at runner envelope (10) installs runner (12).
After pressure flow flows into spirality water conservancy diversion Taper Pipe (5) by flume (1), because the flow cross-section of water conservancy diversion Taper Pipe (5) diminishes gradually, so the speed of current increases gradually, and because the water conservancy diversion Taper Pipe is spiral-shaped, so the direction of current also changes gradually, last current enter runner (12) with Peak Flow Rate and best water inlet angle by fixed guide vane (8) and movable water distributor (9), make runner have kinetic energy and the rotation (circular rector) required to pressure flow, make rotary wheel of water turbine reach desired rotating speed because pressure flow passes through spirality water conservancy diversion Taper Pipe from flume from face, when entering runner envelope (10), seat ring and movable water distributor (9) directly pass through on earth by certain sense of rotation, so the local head loss of current is very little, so the efficient of water turbine also improves a lot.
As shown in Figure 2, on the base plate of flume (1), install 6 conical pipelines (5) that tilt by a sense of rotation respectively, constitute diversion component, the interdependent respectively top that is packed in seat ring (15), the bottom of 6 conical pipelines, and make the bottom shape of conical pipeline (5) relative with the shape on seat ring (15) top consistent.Convenient for the installation and removal that make speeding deflector, 6 conical pipelines are divided into two, and to save flange (16) affixed.Install runner envelope (10) between seat ring (15) and the draft tube (11).Install guide bearing (14) in the inside of seat ring (15), guide bearing (14) is equipped with main shaft (13), and the end that main shaft (13) is positioned at runner envelope (10) installs runner (12).
After setting-out stream flows into 6 conical pipelines (5) by flume (1), because the flow cross-section of conical pipeline (16) diminishes gradually, so the speed of current in conical pipeline (5) increases gradually, and because 6 Taper Pipe roads tilt by same sense of rotation, form certain rotation when making current flow out diversion component, last current enter runner (12) with Peak Flow Rate and best direction by seat ring (15), make runner have kinetic energy and the rotation (circular rector) required, thereby make rotary wheel of water turbine (12) reach the rotating speed that requires pressure flow.Because pressure flow when flume (1) enters runner (12) by diversion component and seat ring (15), directly passes through on earth by a straight line direction, so the local head loss of current is very little, so the efficient of water turbine also improves a lot.
As shown in Figure 3, the waterexit end of flume (1) be fixed with interior aqueduct (2) and outside aqueduct (3), formed the cone barrel type runner, interior aqueduct (2) and outside install by 4 spirality diaphragms (4) between the aqueduct (3), diaphragm (4) is by dull and stereotyped affixed the forming of several piece.Thereby form the diversion component that constitutes by 4 spirality water conservancy diversion Taper Pipes (5).The other end of interior aqueduct (2) and outer aqueduct (3) installs movable water distributor (9), installs runner envelope (10) between movable water distributor (9) and the draft tube (11), is equipped with runner (12) in runner envelope (10).
Its working principle is as first embodiment.
