| Abstract: | In view of the problem of the condensate pump playing no more role in the operation after improvement owing to restraint of the sealed water pressure of the pump, the improvement of sealed water system and its shaft seal form has been put forward so as fully to play the potential energy-saving role of the frequency conversion of condensate pump and to improve the water level control of the deaerator. The practice shows that the energy-saving rate of the frequency conversion pump is increased from 38.43% into 61.21%. |
