Abstract: The structure and cardinal principle of the system have been expounded.The dynamicalmathematical expressions of the f2~Urf of the inverter,the nm~f2 of the motor,the Mp~npof the sand pump,and the Qp~np of the sand pump have been set up.The system simulation has been completed. The practical use has been discussed.
