The utility model relates to a water intake system for a flow channel cover plate of a bulb tubular type hydraulic turbine generator. The water filter tank is connected with the water filter tank on the flow passage cover through the pipe, and the water inlet is provided on the other side of the water filter tank. connected. The runner cover is arranged on the water passage, and the water inlet is set on the runner cover, which enters the cooling system of the generator set for cooling, and finally the cooling water after heat exchange is discharged into the runner, realizing where the cooling water comes from. The cycle is eliminated; the equipment is centrally arranged, the pipeline is short and does not need to be embedded, and the assembly and disassembly is convenient for the daily operation and maintenance of the power station, which improves the operating reliability of the unit, and can also realize the automatic flushing function of some pipelines, so that the hydro-generator unit operates well .
Description
[technical field]
The utility model belongs to the power generating equipment technical field, relate to a kind of adopt the equipment centralized arrangement concentrate water-supply method, from the scaled bulb tubular hydraulic generator flow passage cover plate water intake system of generator flow passage cover plate water intaking.
[background technique]
The water-supply method of existing water power plant cooling water mainly contains two kinds: a kind of is to fetch water from the water power plant upper pond, pressurize by water pump, water purifier filtration, entering generator set through pre-buried water pipe cools off, this water-supply method major defect is that pipeline length and major part are embedded in the concrete, long operational time, pipeline can stop up to some extent, and pipe resistance increases and bad elimination; Another kind is that cooling water recycles, " water-water " cooler by external river course cools off circulating water, pressurize by water pump then, entering generator set through pre-buried water pipe cools off, this mode major defect is that " water-water " cooler is covered by aquatic organism easily, and the radiating effect variation needs often to remove aquatic organism, especially at southern area, be exactly to need often to replenish purified water in addition to cooling system.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of equipment centralized arrangement, pipeline to need not pre-buried, as to install and remove conveniently, maintain easily power station day-to-day operation, can also realize the scaled bulb tubular hydraulic generator flow passage cover plate water intake system to the automatic washing capacity of section of tubing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of scaled bulb tubular hydraulic generator flow passage cover plate water intake system, water flow passage was arranged, be furnished with flow passage cover plate on the water flow passage excessively, flow passage cover plate is provided with intake, intake links by the water filtering tank on pipeline and the flow passage cover plate, opposite side at water filtering tank is provided with water intake, and this water intake links with water pump, safety check, butterfly valve one, water filter and generator set cooling system successively by pipeline.
Described generator set cooling system links with the mistake water flow passage by pipeline and butterfly valve two.
Be furnished with pressure switch and differential pressure transmitter in described pipe-line system.
The beneficial effects of the utility model are: flow passage cover plate was arranged on the water flow passage, on flow passage cover plate, be provided with intake, by arranging that two standby each other water pumps on it pressurize, then through arranging two standby each other water filters on it, entering the generator set cooling system cools off, cooling water through heat exchange enters runner at last, has realized that cooling water comes circulation where wherefrom.Whole tubing is furnished with pressure switch and differential pressure transmitter, when intake or line clogging cause resistance excessive, pressure switch and differential pressure transmitter signal, and make up by valve and water pump to system, just can realize intake and section of tubing are carried out backwash.Equipment centralized arrangement, the day-to-day operation that pipeline is short and it is pre-buried to need not, mounting or dismounting make things convenient for the power station are safeguarded, have improved the unit operation reliability, can also realize the automatic washing capacity to section of tubing, and the hydraulic generator unit is well moved.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-intake, 2-water intake, 3-butterfly valve one, 4-safety check, 5-water pump, 6-water filter, 7-butterfly valve two, 8-water filtering tank, 9-cross water flow passage, 10-flow passage cover plate, 11-pipeline, 12-differential pressure transmitter, 13-pressure switch.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, a kind of scaled bulb tubular hydraulic generator flow passage cover plate water intake system, be furnished with flow passage cover plate 10 on the water flow passage 9 excessively, flow passage cover plate 10 is provided with intake 1, this intake 1 is the starting point of whole system, water filtering tank 8 companies of linking on this intake 1 and the flow passage cover plate 10, water filtering tank 8 plays the effect of preliminary filtration, after the cooling water after preliminary the filtration is by water pump 5 pressurizations, by pipeline 11 by safety check 4, butterfly valve 1 enters water filter 6, the cooling water that is come out by water filter 6 can satisfy the cooling requirement of generator set cooling system substantially, enter the generator set cooling system from pipeline 11 then and cool off, after entered water flow passage 9 by pipeline and butterfly valve 27 after the heat exchange; Wherein fetch water, cooling and drainage path be followed successively by: the water filtering tank 8 of the water of crossing 9 li of water flow passage to the flow passage cover plate 10, again after water pump 5 pressurizations, pass through safety check 4, butterfly valve 1, water filter 6 more successively to the generator set cooling system, enter runner through the cooling water after the heat exchange by butterfly valve 27 and pipeline 11 at last.Realized that like this cooling water comes circulation where wherefrom.Be furnished with pressure switch 13 and differential pressure transmitter 12 in described pipeline 11 systems.When intake 1 or pipeline 11 stops up when causing resistance excessive, pressure switch 13 and differential pressure transmitter 12 signal, and make up by valve and water pump 5 to system, just can realize intake 1 and section of tubing are carried out backwash.
