水环泵工作水温对双背压机组的影响

Water Ring Pump Water temperature on the Effect of Double back Pressure Unit

目前省内多台电厂在夏季高背压侧凝汽器端差偏大,根据理论分析了水环泵工作水温度对机组真空的影响,结论是凝汽器端差偏大的原因是水环泵工作水温度偏高,提出采用双背压凝汽器的机组应该重视降低工作水温度,以体现双背压凝汽器优势和达到节能降耗的目的。

High terminal temperature difference of turbine condenser is occurred with many power plant in summer, by theoreticaly analysizing the effect of working water temperature of water-sealed pump on condensor vacum, the paper draw a conclusion that the hight temperature of water--sealed pump woring water is the mayor reason. At last, the paper suggest more attention should be put on the working water temperature of water-sealed pump with double back-pressure units for the advantage of double back-pressure condenser and the aim of energy saving and consumption reduction.
