Embodiment

[0039] H city pipeline two-way booster pump station project, such as Figure 7-Figure 12 As shown, there are 9 electric valves, two water plants distributed from east to west, clear water pool on the right, 3 pipeline booster pumps (first phase project), and 2 pool booster pumps (long-term project).

[0040] At present, the water supply capacity of A water plant and B water plant in H city has reached 300,000 m 3 / d, both water plants are in a state of oversupply, and the surplus capacity is basically 100,000 m 3 / d above. When water plant A fails to supply water normally due to raw water or operation management problems, the pump station undertakes the task of emergency water supply (mainly domestic water) in the west of city H; when water plant B fails to supply water normally due to raw water or operation management problems, the pump station Undertake the task of emergency water supply (mainly domestic water) in the eastern part of H City. The pressurized scale of this ...

Abstract

The invention discloses a two-way pressurization system for pipelines. There are no more than 9 electric valves in total, and through 6 groups of switching combination modes, it can realize the direct pressurization scheme of the pipeline, the pressurization scheme of the water pool and the combined pressurization scheme of the pipeline and the pool. Switching between schemes. Aiming at the characteristics of single urban water supply source, narrow and long terrain, unbalanced water supply, and insufficient emergency backup, the present invention solves the problem of difficult linkage of multiple water plants and cannot be used as backup for each other, and provides a two-way water pump with simple technical equipment, rapid switching, and easy management. Supercharged emergency technology. The invention can be used for the emergency plan of the water supply pipeline, and can also be used for improving the transfer capacity of other pressurized pipelines, realizing efficient switching and effective response.

Description

technical field [0001] The invention relates to safe water supply technology, and discloses a pipeline bidirectional supercharging system with combined supercharging and bidirectional switching function. Background technique [0002] The city has obvious characteristics of narrow and long topography, and when the urban water source is located at the two ends of the administrative division, the distance between the water plants is relatively long, and the construction of the connecting pipe is not perfect, and the diameter of the pipe is too small, so that the two water plants cannot completely serve as backup for each other. Sudden shutdown of a certain water plant will cause some towns in the city to be unable to supply water, which poses a huge risk to the safe water supply of the entire city. [0003] In addition, when the quality of urban water sources is poor and single, if all the water used in the city is taken from river network water, although the current treatment ...
