Abstract

Abstract: In the variable frequency reformation of the condensate pump, for optimizing the technical indicators of the water level control system of the deaerator, after the water level adjusting valve was fully opened, as a trial, the water level control was switched over without disturbance to the frequency converter control. The new method can reduce the throttling loss of the valve and the power consumption of the condensate pump, and obtain favorable economical benefit.

Key words: control system, switchover without disturbance, variable frequency reformation, economical benefit
