Single-fossil-fired power plant coagulation frequency conversion pump put into operation initial results

On September 25, 3 # condensing frequency conversion pump of No. 3 steam turbine generator set of thermal power plant was officially put into operation. The transformation of No. 3 variable frequency pump is an important technical reform project of thermal power plant overhauling this year. After the transformation of the No. 3 condensing pump to achieve a condenser can automatically adjust the water level effect.
After the installation of No.3 frequency conversion pump, the running unit steam workshop will send someone to debug and try out the pump. The debugging includes the electrical interlock between the pumps and the interlock between the pump and the system. Because the No. 3 pump is a newly installed frequency conversion pump, there will be some problems when it is put into operation for the first time. In view of this situation, the workshop devoted to the establishment of the relevant management regulations, requiring staff positions in strict accordance with the provisions of the implementation of the operation closely monitor the operation of pump No. 3 to strengthen the inspection of the pump. Workshop stressed that in the process of operation of the pump once the operating parameters of over-limit or pump abnormal phenomenon should immediately stop running for inspection.

At the moment, pump No. 3 is operating normally. After the transformation of the No. 3 pump to achieve the condenser water level can automatically adjust the purpose, while maintaining the condenser steam low water level operation. The vacuum relative to the condenser and the economy of the unit have been increased. On the one hand to simplify the operation of personnel, replacing the frequent adjustment of the operator in the past to a certain extent, saving electricity, to achieve the purpose of saving energy and reducing consumption, but also to ensure the safe and stable operation of the unit.
