Abstract: The fan pump is widely used in the highspeed paper machines stock on system. The innovation of the fan pump with AC inverter was introduced which based on the speed control theory realized PID control by pressure transmitter. The result proved that the installation of AC inverter for the fan pump system can adapt to the different speed and grade, and finally the new system will run in the best state, make the process conditions in stable state. The use of AC inverter instead of the valve will cut down the energy loss and achieve 30% by energysavingrate.
