汽轮发电机组真空压力偏低及波动的原因分析

Analysis on Causes of Abnormal Low Level and Fluctuation of Vacuum in Turbo Unit

中国石化上海石油化工股份有限公司热电部1#热电联合装置2#汽轮发电机组凝汽器的真空压力时常发生波动,而夏季时的真空压力则一直偏低。经过分析,发现是真空泵冷却水温度偏高所致。文章根据真空泵的工作过程和原理,对真空泵冷却水系统的改造和维护提出了建议。

In view that vacuum in condenser of 2# turbo unit of 1 # Thermal United Plant of SINOPEC Shanghai Petrochemical Co. , Ltd. fluctuated frequently, and was abnormally low in summer, discussion was made causes, and was found to be abnormally high temperature of cooling water in the vacuum pump. Based working process and principle of vacuum pump, proposals were raised on revamp and maintenance of water system in the vacuum pump. on the on the cooling
