摘要
电厂母管制系统中给水泵及循环水泵,凝结水泵在变化运行泵台数或采用变速泵后,了解管路及泵的流量分配规律对优化调度及泵的优化选型以及安全运行十分重要,然而,有关这方面的资料及文章却少见到。为此,本文以北京第一热电厂为例。提出一个确定母管制系统中泵及管路流量的图解法与计算法。
It is very important to good running,type selection and safety running of the pumps to understand flow distribution law of the pipe line system and pumps,after the number of the boiler feed pumps the circulating water pumps and the condenser pumps of mam-line type are changed,or after the variable speed pumps are put into operation.However,there are the shortage of such materials and papers now.In this paper,we take the case of Beijing No.1 power plant and present a diagram method and a calculation method for determining the flow capacity of boiler feed pumps in main-line type and pipe line system.
