海水直流冷却系统中立式混流泵选型和防腐问题研究

Probe into vertical mixed-flow pump selection and anticorrosion in the sea water direct-flow cooling system

立式混流泵作为海水直流冷却系统的核心设备,选型应兼顾可靠性、经济性和维修便利性。以某滨海石化厂的海水立式混流泵为实例,探讨了立式混流泵选型时需考虑的问题,并重点介绍了立式混流泵在海水介质中的防腐蚀措施。

The vertical mixed-flow pump is the key equipment of the sea water direct-flow cool- ing system. Its equipment selection should comprehensively take consideration of stability, econo- my, and easy maintenance. Using the sea water vertical mixed-flow pump in a costal petrochemical plant as an example, this paper discussed the problems worthy of consideration in equipment selection and introduced the anticorrosive measures for the sea water vertical mixed-flow pumps with emphasis.
