热电厂给水泵车削叶轮节能技改应用研究

Thermal power plant feed-water pump turning impeller energy-saving technological transformation applied research

徐州华美热电公司2×55MW热电厂配备的额定流量为286t/h的锅炉给水泵,运行中暴露出来给水压力富裕量过大,存在着较大的压力节流损失,造成电能浪费等问题,由于电机常处于过负荷状态,影响设备安全。对给水泵的技术改造进行了研究,着重探讨了车削定速给水泵叶轮技改的节能机理,并对其改造方法、改造实例和改造效果进行了分析。

Take the 286t/h boiler feed pump for the object of study,which provided by the Xuzhou Huamei Thermal Power plant 2×55MW unit,specifically for the problem that it's operation shows in:oversized for the hydraulic pressure wealthy quantity,the tremendous pressure restriction loss,creates the electric quantity waste,When movement to conserve energy often causes the electrical machinery to be at the load conditions,influence equipment security.conducted the research to feed pump's technological transformations,discussed the turning constant speed feed pump impeller technological transformation energy conservation mechanism,and its transformation method.The transformation example and the transformation effect has carried was analysised.
