Description
Technical field
The utility model relates to a kind of horizontal water turbine, especially relates to a kind of pump plate structure of horizontal water turbine.
Background technique
Hydraulic turbine generator refers to water turbine to be that water can be converted into the turbine-generator units of electric energy by prime mover.Current, through water turbine, can convert water to mechanical energy, and the rotor of the rotating shaft of water turbine drive electrical generators again, converting mechanical energy to electric energy and export, is the main dynamics equipment that water power plant produces electric energy.
Hydraulic turbine generator can be divided into vertical and horizontal two classes by axial location.Big-and-middle-sized unit generally adopts vertical, and horizontal layout is generally used for small unit and bulb-type tubular hydro set.
At present, along with Qinghai, Xinjiang, Tibet High aititude, the water power market that sediment charge is larger is developed further, solve horizontal hydraulic machine equipment in the stable operation of high silt power plant safety, imperative, so, adopt a kind of new structure in high concentration of sediment power station, reduce because of long-time running, the economic loss that needs are often changed rotatable parts and caused.
Model utility content
In order to overcome the deficiency that prior art exists, the utility model provides the pump plate structure of the horizontal water turbine that a kind of installation and maintenance are convenient, unit operation stability is good.
A pump plate structure for horizontal water turbine, comprise runner, main shaft, top cover, the first water shutoff chamber, the second water shutoff chamber, described pump plate structure also comprises pump plate, and described pump plate is fixed on runner, and pump plate offers breach; Described top cover is provided with seal ring, and respectively and runner, there is gap between main shaft, the seal ring near runner place is provided with the first labyrinth seal chamber to described seal ring, and the seal ring near main shaft place is provided with the second labyrinth seal chamber.
The utility model pump plate has breach, makes it can produce pump efficiency in rotary course and answer, the water of runner epicoele and silt are discharged, improves the operation stability of unit; The first labyrinth seal chamber on seal ring and seal ring, the second labyrinth seal chamber are arranged, and more effectively avoid soil erosion and injure main shaft, reduce water more and enter main shaft, realize good sealing.
As preferably, described top cover is provided with through hole, and described through hole is connected with the first water shutoff chamber.Water in running between pump plate and top cover and silt are discharged to the first water shutoff chamber by through hole under the effect of pump plate, then drain into tail water or sump.
As preferably, described second water shutoff chamber is positioned at below the first water shutoff chamber.Current in first water shutoff chamber are high pressure water, and the current in the second water shutoff chamber are that low pressure is leaked, and the structure adopting the first water shutoff chamber, the second water shutoff chamber current separately to discharge, prevents the water in the second water shutoff chamber from cannot discharge.
As preferably, described pump plate is fixed by screws on runner.
As preferably, described seal ring is put together on top cover by screw.
The utility model structure is simple, reasonable in design, has the features such as easy for installation, easy to maintenance, unit ride quality steady in a long-term is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of pump plate structure of horizontal water turbine, comprise runner 1, main shaft 2, water shutoff chamber 5, top cover 3, first water shutoff chamber 4, second, described pump plate structure also comprises pump plate 6, and described pump plate 6 is fixed by screws on runner 1, and pump plate 6 offers breach; Described top cover 3 is provided with seal ring 8, and described seal ring 8 is put together on top cover by screw.Respectively and runner 1, there is gap between main shaft 2, the seal ring be connected with runner 1 is provided with the first labyrinth seal chamber 9 to described seal ring 8, and the seal ring be connected with main shaft 2 is provided with the second labyrinth seal chamber 10.
Described top cover 3 is provided with through hole 7, and described through hole 7 is connected with the first water shutoff chamber 4, and described second water shutoff chamber 5 is positioned at below the first water shutoff chamber 4.
Pump plate 6 is fixed on runner 1 by screw and rotates together with main shaft 2, pump plate 6 has breach make its produce in rotary course pump efficiency should, water in running between pump plate 6 and top cover 3 and silt are discharged to the first water shutoff chamber 4 by through hole 7 under the effect of pump plate, then drain into tail water or sump.Because the current in the first water shutoff chamber 4 are high pressure water, the current in the second water shutoff chamber 5 are that low pressure is leaked, and the structure adopting the first water shutoff chamber, the second water shutoff chamber current separately to discharge, prevents the water in the second water shutoff chamber from cannot discharge.Seal ring 8 puts together on top cover 3 by screw, and the material of seal ring 8 adopts ZCuAl10Fe5Ni5, and runner 1 material adopts OCr13Ni4Mo, and both have difference of hardness by material, and runner can be made to be protected better.And in order to more effectively guarantee that main shaft 2 is not injured by soil erosion, the seal ring be connected with runner 1 is provided with the first labyrinth seal chamber 9.Be provided with the second labyrinth seal chamber 10 same with on the seal ring that main shaft 2 is connected, water can be reduced more and enter main shaft, avoid main shaft to damage.
