Description
Technical field
The present invention relates to hydraulic generator unit technology, particularly relate to a kind of cooling water system of scaled bulb tubular hydraulic generator group.
Background technology
The type of cooling of the large and medium-sized scaled bulb tubular hydraulic generator group of moving in the prior art can be summarized as following two 2 kinds:
First kind: the secondary cooling system of " aerial cooler-water cooler ".
Aerial cooler is arranged in generating cabin air circulation flow process, arranges similar with the aerial cooler of common vertical unit." water cooler " of scaled bulb tubular hydraulic generator group is then according to the size of unit capacity; Two kinds of arrangements are generally arranged: a kind of is the coolant jacket form; Promptly 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 irrelevant basically.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; In bulb, the generate electricity cooling medium (air) of cabin of the heat that produces during generator operation passes to the recirculated water in the 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.Because cooling water is recycling, and is 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.
Second kind: a type of cooling of aerial cooler (being the acyclic type of cooling).
The scaled bulb tubular hydraulic generator group 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 so be called the type of cooling again one time.Because the cooling capacity of heavy-duty generator corresponding requirements is big, thereby the cooling water amount is also bigger, causes corresponding cooling water pipe caliber bigger thus, the layout of supply equipment and pipeline is difficulty.
