摘要
汽蚀现象在水泵运行中经常发生,其对设备和系统带来诸多不利影响。尤其是电站的一些水泵,工作环境比较恶劣,对系统运行又非常重要,需要更加注重汽蚀的防范。研究汽蚀发生的机理和影响因素,探讨汽蚀的防预方法,有针对性地采取措施是非常重要的。
The phenomenon of cavitation is of frequent occur- rence during pump operating, and it always brings some unfavorable influence to the equipment and system. Especially in the power plant, some pumps work in the mal-condition, but they take important place in the system, then we should taks more attention to the preventing of cavitation. On this pa- per, we studied the mechanic and factor of the cavitaton, discussed the methods of preventing cavitation. And then it is important to adopt measure targetedly.
