Abstract
The utility model relates to a kind of arrangement that improves pumped storage power plant tail water pipe import minimum pressure.The technical scheme that the utility model adopts is: a kind of arrangement that improves pumped storage power plant tail water pipe import minimum pressure, there are a tailwater tunnel and some pump turbines, corresponding every pump turbine is provided with the tail water arm of a connection tailwater tunnel, between each tail water arm, be connected through a tail lock hole, it is characterized in that: between the tail water arm of downstream, described tail lock hole, set up communicating pipe.Pressing close to tail lock hole described communicating pipe arranges.The beneficial effects of the utility model are: the utility model is simple in structure, easy construction, engineering drop into lower, especially can effectively solve the problem of tailwater tunnel import minimum pressure from longer power station for the bifurcated pipe causing compared with needs long or that each hydraulic structure is arranged due to Geological Reasons tail water arm and unit spacing, for unit safety operation provides safeguard.
Description
Technical field
The utility model relates to a kind of arrangement that improves pumped storage power plant tail water pipe import minimum pressure.Be applicable to Hydraulic and Hydro-Power Engineering.
Background technology
If draft tube import minimum pressure can not meet the demands, cause the generation of draft tube liquid note segregation phenomenon, produce thus direct water hammer, may cause unit to lift machine major accident.Pumped storage power plant working conditions change is frequent, Calculations of Hydraulic Transient complicated condition, one hole multimachine is arranged under general layout, removal of load operating mode is in succession the controlled operating mode of draft tube import minimum pressure, situation about especially needing for geology or structural configuration and cause tail water arm to be grown, the more difficult satisfied control requirement of draft tube import minimum pressure.This problem is perplexing correlation engineering technician always, not yet has good mode to solve the problem of draft tube import minimum pressure under removal of load operating mode in succession.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, easy construction, lower, the safe and reliable arrangement that improves pumped storage power plant tail water pipe import minimum pressure of cost.
The technical scheme that the utility model adopts is: a kind of arrangement that improves pumped storage power plant tail water pipe import minimum pressure, there are a tailwater tunnel and some pump turbines, corresponding every pump turbine is provided with the tail water arm of a connection tailwater tunnel, between each tail water arm, be connected through a tail lock hole, it is characterized in that: between the tail water arm of downstream, described tail lock hole, set up communicating pipe.
Pressing close to tail lock hole described communicating pipe arranges.
The beneficial effects of the utility model are: the utility model is simple in structure, easy construction, engineering drop into lower, especially can effectively solve the problem of tailwater tunnel import minimum pressure from longer power station for the bifurcated pipe causing compared with needs long or that each hydraulic structure is arranged due to Geological Reasons tail water arm and unit spacing, for unit safety operation provides safeguard.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
Detailed description of the invention
As shown in Figure 1, the present embodiment is a kind of arrangement that improves pumped storage power plant tail water pipe import minimum pressure, there are a tailwater tunnel 1 and three pump turbines 5, between every pump turbine 5 and tailwater tunnel 1, be connected by a tail water arm 2,2 of each tail water arms are connected through a tail lock hole 3.In this example, between the adjacent two tail water arms 2 in 3 downstreams, tail lock hole, set up communicating pipe 4, be laid in tail lock hole 3 communicating pipe 4 afterwards and the tail lock layout of trying one's best.Communicating pipe, basal area only needed 1/2nd of tail water arm basal area.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation made, change and add or replace, all should belong to protection domain of the present utility model.
Claims (2)
