Second, the performance requirements of the pump
Raw water to take, lose, with water pump
1, continuous operation, high reliability requirements
2, take, lose combined and half-way pressurized water flow and head
relatively stable
3, take, lose, mix with the water flow and head is relatively stable
Change big
4, the requirements of the pump efficiency and good cavitation performance area wide
5, the original high water content of sand with water contact with the material wear-resistant high
6, raw water chloride contact with high water resistance of chlorine material requirements
Water plants and water mains pressurized water transport, distribution pumps
1, continuous operation, high reliability requirements
2, a single water delivery water flow and head is relatively stable
3, the transmission and distribution combined with the water flow and head relative
Stable change
4, requiring high efficiency pump area and cavitation performance excellent wide area
