Abstract
Condensate pump is employed to pump the water in condenser to deaerator, maintains the water height in deaerator and enables units operate continuously. Currently, system efficiency of 600 MW units is comparatively low due to high design pressure head and large throttling pressure loss. This paper takes NLT500-570x4S condensate pump as example, and analyzes its existing problems based on performances test. Further, aims at solve these problems, some modification works, such as reducing the throttling pressure loss and reforming the through-flow as well as improving the craft of inspection, are performed. The results show that the highest efficiency of the condensate pump was improved with 5.5% under the best design flux.
