Embodiment

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

[0040] At present, the water supply capacity of Water Plant A and Water Plant B in City H has reached 300,000 m 3 / d, the two water plants are in a state of oversupply, and the surplus capacity is basically 100,000 m 3 / d above. When water plant A cannot supply water normally due to raw water or operation management problems, the pump station assumes the task of emergency water supply (mainly domestic water) in the western part of H city; when water plant B cannot supply water normally due to raw water or operation management problems, the pump station To undertake the task of emergency water supply (mainly domestic water) in the eastern part of H City. The pre...

Abstract

The invention discloses a pipeline two-way supercharging system. Not more than 9 electric valves are arranged, six groups are used for switching combination modes, the pipeline two-way supercharging system achieves switching of three schemes of a direct supercharging scheme of a pipeline, a water pond supercharging scheme and a pipeline and water pond combined supercharging scheme. The pipeline two-way supercharging system solves the problems that a plurality of water plants are difficult to be in linkage and cannot be in mutual standby use because of the characteristics that a city water supplying water source is singular, the terrain is long and narrow, water supplying is not in balance and emergency standby use is not sufficient. A two-way supercharging emergency technology simple in technical device, fast to switch and easy and convenient to manage is provided. The pipeline two-way supercharging system can be used for emergency planning of a water supplying pipeline, and can also be used for improvement of the transfusion capacity of other pipelines under pressure, and efficient switching and effective coping are achieved.

Description

Technical field [0001] The invention relates to a safe water supply process technology, and discloses a pipeline two-way pressurization system with combined pressurization and a two-way switching function. Background technique [0002] The city has obvious characteristics of long and narrow terrain. When the water source of the town is located at both 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 pipe diameter is too small. As a result, the two water plants cannot be fully standby for each other. Sudden shutdown of a 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, such as all water used in the city is taken from river network water, although the current municipal water plant treatment facili...
