摘要
文章介绍了变频调速技术的工作原理,给出了普通海水泵和恒压变频海水泵的功耗计算公式。基于现有欧亚航线上的20000 TEU级集装箱船对海水冷却系统进行方案设定,给出中央出冷却水系统和逻辑控制系统的设计方案;通过计算分析了普通海水泵变频和恒压变频海水泵在能耗上的差异,验证了能耗计算的准确性。为降低船用变频调速控制系统的能耗与成本,提供了计算方案。
The working principle of variable frequency technology is introduced.The calculation of efficiency and energy consumption for normal marine seawater pumps and constant-pressure variable-frequency seawater pump are proposed.Based on the existing 20000 TEU container vessel on the existing Eurasian route,the seawater cooling system is set,and the design scheme of the central cooling water system and the logic control system is given.The difference in energy consumption between the ordinary seawater pump and the constant-pressure variable-frequency seawater pump is analyzed through calculation.In order to reduce the energy consumption and cost of the marine variable frequency speed control system,a calculation scheme is provided.
