Abstract: The function of low-pressure heater drainage pump is to drain condensation water from a low-pressure heater and to send the water to an oxygen remover, thus to raise heating efficiency. Introduction was made to equipment abnormal situation before low-pressure heater drainage pump rebuilding in a company, and actual rebuilding technical plan was raised to change models of drainage pump, to adopt variable frequency control for the control part. Actual operation result shows that after rebuilding the equipment, power saving rate reaches 65% in average, to have lifted control operation in real-time and reliability.
         Key words: low-pressure heater drainage pump; inverter; rebuilding
