摘　　要：结合热轧或CSP冷却工艺特点与要求,通过对水泵及泵组运行特性分析,认为水泵变速调节不能满足热轧或CSP冷却水恒压力、变流量控制要求,即低压浊环水、高压浊环水的节能改造不适宜采用水泵调速方式;层流冷却水压力低,调速节能改造是有条件的。Combining the traits and demands of cooling technology for hot strip mills or CSP,the operating characteristics of water pump and water pump unit are analyzed.The analysis shows that speed control of the water pump can not meet the needs of constant pressure cooling water for hot strip mills or CSP and control of variable flow,i.e.mode of speed control of water pump is not suitable for energy saving in turbid circulating water with low pressure and high pressure.The laminar flow cooling water has a low water pressure if speed control of water pump is used.Application of the speed control of water pump is limited.
