Urban flood control and drainage
Urban flood control and drainage, generally take water storage measures in the upper reaches of the river to , such as planting trees and grass, water and soil conservation, construction of reservoirs. The middle reaches are dominated by flood drainage and water containment, such as river channel improvement, building of embankments (or flood walls), setting up flood drainage pumping stations, etc. In addition to flood discharge and water blocking works, the downstream should also consider the sea tide prevention works, such as the construction of seawall, moisture-proof gates and other facilities. Non-engineering measures such as flood diversion and detention should be considered when necessary. Cities threatened by mountain torrents should set up flood interception ditches according to the characteristics of mountain torrents and topographic conditions.
Submersible axial flow pump is widely used in urban flood control and drainage, industrial and agricultural water transport, urban water supply, mild sewage discharge and water transfer projects.
It has the characteristics of large flow, wide head range and high efficiency. Submersible motor and water pump integrated structure, diving into the water to run, with the incomparable advantages of traditional unit :
Greatly simplify the construction projects of the pump station, and save 30%-40% of the total construction cost of the pump station.
Easy maintenance, leakage and internal winding temperature rise protection device, can be equipped with control cabinet, operation reliable.
Low noise and long life
