Abstract
The utility model relates to power generation equipment, in particular to a self-draining runner of a water turbine. The self-draining runner mainly aims to solve the technical problems that in the prior art, when an existing water turbine runs, a certain gap needs to be reserved between a runner and a leakproof ring, so that water leakage is caused; currently, leaked water at the position of a top cover is generally passively drained through the sealing positions of drainage holes and a main shaft seal, so that the pressure of the top cover is large, the temperature of a thrust bearing pad is high, and a main shaft and the main shaft seal are damaged; when a labyrinth is abraded, the water leakage amount is larger, when the water leakage amount exceeds the drainage amount of the drainage holes and the main shaft seal, water overflows and rises and can submerge an oil lubrication water guide bearing, and normal running of a unit is directly affected when the situation is severe. The self-draining runner comprises a runner crown (1), the runner crown (1) is connected with a runner lower ring (3) through a runner blade (2), a pump cover plate (4) is fixed to the upper end face of the runner crown, and more than three rib plates (5) are arranged between the pump cover plate and the runner crown and are circumferentially distributed.
Description
Technical field
The utility model relates to a kind of power generating equipment, especially relates to a kind of water turbine from draining runner.
Background technique
At present, existing hydroelectric generator is mainly that the drop by current generates electricity, and first wants ponding, by certain height, after formation hydraulic pressure, with the water turbine of generator, generate electricity, i.e. so-called drop hydroelectric generator, be mainly used in mountain region, hills, drop is larger, water flow is also larger.Chinese patent discloses a kind of hydroelectric power unit (publication number: CN 101545444A), it comprises a fixing frame, at fixing frame, be provided with generator, below fixing frame, be provided with successively a plurality of slip rings, at each slip ring outlet end, be provided with the water wheels assembly that can rotate under natural flowing water drives, asking of water wheels assembly and generator, be provided with driving mechanism, the water wheels assembly front end under fixing frame is provided with the adjustable controlling device that enters the water flow size of water wheels assembly; Slip ring is the housing of a cone-shaped, and its entry end is greater than outlet end, before each controlling device is located at respectively water wheels assembly; Controlling device is included in a plurality of adjustment sheets that water wheels assembly space before arranges, and adjustment sheet is arranged on rotatingshaft, is provided with pivoted arm on rotatingshaft, and pivoted arm is regulated by pull bar, is provided with the power piston that can drive pull bar work on pull bar; Pull bar comprise be connected with power piston promote mainly pull bar and the attached pull bar being connected with pivoted arm, by triangle lever, connect promoting mainly between pull bar and attached pull bar.But this water turbine, when operation, must leave certain gap between runner and seal ring, leaks, and the discharge that existing top cover place leaks is generally by the passive discharge of spilled water hole and main shaft seal place, this mode, top cover pressure is large, thrust bearing shoe valve temperature is high, and main shaft and main shaft seal are had to infringement.After the wearing and tearing of labyrinth, to leak larger, while surpassing spilled water hole and main shaft seal place discharge capacity, spilling water rises, and can flood the water pilot bearing of oil lubrication, directly affects the normal operation of unit when serious.
Model utility content
The utility model is to provide a kind of water turbine from draining runner, it is mainly to solve the existing water turbine of prior art when operation, between runner and seal ring, must leave certain gap, can cause and leak, and the discharge that existing top cover place leaks is generally by the passive discharge of spilled water hole and main shaft seal place, top cover pressure is large, thrust bearing shoe valve temperature is high, main shaft and main shaft seal are had to infringement, after the wearing and tearing of labyrinth, leak larger, while surpassing spilled water hole and main shaft seal place discharge capacity, spilling water rises, can flood the water pilot bearing of oil lubrication, when serious, directly affect the technical problem of the normal operation etc. of unit.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of water turbine of the present utility model, from draining runner, comprises runner crown, and described runner crown connects runner lower ring by runner bucket, the upper-end surface of runner crown is fixed with pump closure, between pump closure and runner crown, be provided with gusset, gusset is that more than 3 it is circle distribution.On runner crown, increased by eight gussets and a pump closure, utilize the rotation energy of water turbine, form centrifugal water pump, the sealing that makes to seal on runner seal ring leak and water in sand and other solid matter to head cover drainage, then discharge by head cover drainage pipe.
As preferably, described pump closure place is connected with 4 aqueducts.Water distributor has adopted head cover drainage technology, in top cover lower end, runner crown pump plate place is connected to the aqueduct of four DN50mm, add the gland of putting the sealing of O type circle, can be directly and the draining of new system flange connect or scyewed joint draining, making to leak drains into sump by aqueduct, and does not affect the water shutoff of main shaft seal and the use of water pilot bearing.Thereby reduced leaking of main shaft seal place, effectively prevented that water and solid from entering main shaft seal place, and stoped the harm to water pilot bearing, guaranteed the normal operation of unit.
Therefore, the utility model adds on runner puts pump plate, utilization can be directly and the draining of new system flange connect or scyewed joint draining from discharge structure, making to leak drains into sump by aqueduct, and does not affect the water shutoff of main shaft seal and the use of water pilot bearing, thereby has reduced leaking of main shaft seal place, with cap structure in the lump designing and arranging water lines, lower top cover pressure, reduced thrust bearing shoe valve temperature, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: runner crown 1, runner bucket 2, runner lower ring 3, pump closure 4, gusset 5, aqueduct 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of water turbine of this example, from draining runner, as Fig. 1, comprises runner crown 1, runner crown connects runner lower ring 3 by runner bucket 2, and the upper-end surface of runner crown is fixed with pump closure 4, is provided with gusset 5 between pump closure and runner crown, gusset is that more than 3 it is circle distribution.Pump closure place is connected with 4 aqueducts 6.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
