Description
Technical field
The present invention relates to hydraulic generator unit technology, particularly relate to a kind of cooling water system of bulb tubular hydraulic generating set.
Background technology
The type of cooling of the large and medium-sized bulb tubular hydraulic generating set that moves in prior art can be summarized as following two 2 kinds:
The first: the secondary cooling system of " aerial cooler-water cooler ".
Aerial cooler is arranged in generating cabin air circulation flow process, arranges similar to the aerial cooler of common vertical unit." water cooler " of bulb tubular hydraulic generating set is according to the size of unit capacity, two kinds of arrangements are generally arranged: a kind of is the coolant jacket form, namely one section shell body of bulb is made the interlayer of hollow, the one side that contacts with river adopts stainless clad steel plate.The manufacturing process of the Bulb Turbine Units of this coolant jacket form is complicated, and cost is higher; Another kind is external " water cooler " form, and water cooler independently is arranged in upper pond, unit runner or downstream tail water, and the manufacturing of water cooler and unit is substantially irrelevant.Have the advantages that arrangement is flexible, manufacturing process is simple, cost is lower than coolant jacket, size is huge, pipeline is complicated but exist, and the shortcoming of operation maintenance inconvenience.
Prefilled is in " pure water " of aerial cooler and coolant jacket (perhaps external " water cooler "), circulate through the water pump supercharging, generate electricity in the bulb cooling medium (air) of cabin of the heat that produces during generator operation passes to recirculated water in aerial cooler, recirculated water is passed to coolant jacket or external " water cooler " to heat, is taken away by the river absorption of flow through coolant jacket or external " water cooler " outer wall.Due to the cooling water circulation utilization, higher to water quality requirement, need regular dosing and replenish a small amount of loss, water standard is proposed by the producer that complete coolant equipment is provided.Therefore, the shortcoming that adopts coolant jacket or external " water cooler " mode all to exist cooling capacity to be restricted is not very desirable for the cooling effect of jumbo generating set.
The second a: type of cooling of aerial cooler (being the acyclic type of cooling).
Bulb tubular hydraulic generating set is copied common unit, utilize the hot blast of aerial cooler cooled electric generator ventilating system, the heat that generator produces is all absorbed by aerial cooler, and the cooling water of aerial cooler adopts river, disposable use is therefore be called again the type of cooling one time.Because the cooling capacity of heavy-duty generator corresponding requirements is large, thereby the cooling water amount is also larger, causes thus corresponding cooling water pipe caliber larger, and the layout of supply equipment and pipeline is more difficult.
