pump cavitation

The working fluid is cooled using open circulating cooling water which is introduced from condenser circulating water,and in summer its cooling effect was bad and this leads to the output of vacuum pump to be reduced and cavitation of pump wheel occurred;so that the safety and economical operation of unit had been influenced.

该泵工作液冷却水采用以凝汽器的循环水为水源的开式循环冷却水,在夏季运行时冷却效果差,达不到要求,使真空泵出力下降、泵轮气蚀,影响机组的安全和经济运行。
