The invention discloses a motor pump component rust removal device. The motor pump component rust removal device comprises a shell. A liquid storage box and a water storage box which are symmetricallydistributed are fixedly connected to the outer wall of the shell. Pressurizing pumps and a motor are arranged on the top of the shell. The pressurizing pumps communicate with guide pipes. The ends, away from the pressurizing pumps, of the guide pipes jointly communicate with an annular pipe. The end, away from the motor, of a rotation shaft is in threaded connection with a first motion air cylinder. The end, away from the rotation shaft, of the first motion air cylinder is provided with an electromagnetic suction cup. A motor pump component is adsorbed to the electromagnetic suction cup. A plurality of pulse electromagnetic valves which are symmetrically distributed are arranged on the inner wall of the shell. The bottom wall of the shell is fixedly connected with a second motion air cylinder, and a plurality of plastic suction cups are arranged on the top of the second motion air cylinder and jointly adsorb a cylinder. According to the motor pump component rust removal device, sufficient contact between rust removal liquid and the motor pump component is utilized, effective rust treatment is achieved, and the defects caused by utilizing abrasive paper and a grinding wheel for rust removal are overcome; and meanwhile the motor pump component obtained after rust removal is subjected to cleaning treatment.
