Electric water supply pump is one of the main components of the thermal power generation units

its importance to the unit is self-evident. Because the electric pump recirculation valve often in complex bad working conditions

the valve can easily cause blowing loss phenomenon

resulting in large economic losses and the impact unit. By optimizing the switch logic change electric pump recirculation valve

according to different conditions make the corresponding optimization change

increase the pump recirculation valve operation life

to provide reference for the same type of unit operation mode.
