摘要:

为减少凝结水系统中除氧器水位调节阀的节流损失,降低凝结水泵的耗电率,通过试验摸索,对凝结水泵变频运行方式进行了优化,解决了机组正常运行时凝结水泵变频器的自动投入问题,保证了机组在各种工况下安全、稳定运行,进一步降低了凝结水系统的耗电率。

Abstract:

In the condensate system, in order to reduce the throttle loss of the deaerator water level control valve and reduce the power consumption rate of the condensate pump, by means of test and grope, the variable frequency operation mode of the condensate pump was optimized. When the unit operates normally, the condensate pump converter can be put into operation automatically, the safe and stable operation of the unit under various conditions was ensured, and the power consumption rate of the condensate system was reduced further.
