锅炉给水泵并联运行存在问题的分析探讨

Analysis and Discussion on Problems in Parallel Operation of Boiler Feed Water Pump and Countermeasures

通过分析水泵容积损失和泵内损失的关系、特性曲线特征及水泵并联后的流量变化特征,得出锅炉水泵并联运行时出现故障的原因、解决办法和预防对策。

The relation of water pump volume loss and loss in pump and characteristic curve features as well as flowrate variation characteristics after the pump is paralleled are analyzed.The failure cause in paralle operation of the boiler feed water pump is found out,and the solving method and predictionary measures are proposed.
