摘要
提出了在凝结水泵采用变频调速装置的必要性。本文结合发电厂凝结水泵改造实例,介绍了变频器的主要技术指标、系统配置、运行方式的切换及控制逻辑,并分析了改造后的效果。
The necessity of applying variable-frequency speed-regulating unit to condensate pump is analyzed. Based on actual retrofit examples of condensate pump, an introduction is bing presented to the main technical parameters, system configuration, switchover of operation mode as well as the control logic of the frequency converter, analyses the effect after the modification in the dissertation.
