东北350MW供热机组循泵选型优化分析

Analysis on the Optimization of Type Selection of Circulating Water Pumps of 350 MW Heating Units in the Northeast Region

针对东北地区350 MW供热机组湿冷系统循环水泵选型情况,结合华能大庆2×350 MW热电联产项目对寒冷地区供热机组循环水泵进行选型,结果表明,单级双吸卧式离心泵投资少、检修方便、运行可靠、运行成本低。

In view of the type selection of circulating water pumps of 350 MW heating units in the Northeast Region, the type of circulating water pumps of heating units in cold districts is selected combined with the Huaneng Daqing 2＆#237;350 MW cogeneration project, the results of which show that the single-stage double-suction horizontal centrifugal pumps are of low investment, easy maintenance, reliable operation and low running costs.
