摘　　要：以水力冷却塔水轮机代替电动机驱动风机,节省了电机所消耗的电能,但是水轮机串联于冷却水循环系统中,增加了水循环系统的水力阻力,须消耗一部分水能克服水力阻力。利用试验和数值分析两种方法,研究了水循环系统中水轮机所引起的水力损失特点,提出水轮机节能的措施。Francis turbine replaces the motor to drive the fan on cooling tower, and saves the electric energy of motor. On the other hand, the turbine, which is connected to the cooling water cycle system in series, being series connection of cooling water system, increases the hydraulic head loss of cooling water system, andas well as costs some water energy to overcome itself hydraulic forcemore. This paper studies the hydraulic loss of the turbine by test and CFD. And something areis suggested to decrease the hydraulic loss of turbine.
