Abstract: Introduction was made to a kind of reform plan using one frequency converter to drive two condensate pumps and analysis was made to the working principle and system structure of converter. This paper compared and analyzed variable frequency speed regulation control and working frequency control operation situation of condensate pumps under different load conditions. The result shows that the condensate pump adopting high-voltage variable frequency technology is with obvious energy-saving effect and high safety and reliability.
Key words: condensate pump; frequency converter; energy-saving
