Electric pump from the introduction of high quality prototype developed in Europe and the United States, the technical indicators have reached the level of the prototype, and in the prototype on the basis of the development of different uses different suction liquid series derived products, the series pump Portable tube axial flow pump, with high efficiency, use, easy maintenance and so on. 1, the pump does not run after the power is turned on 1. The power is off 2. The switch contacts burn out 3. The brush can not be reset to wear 4. The armature or (stator) wire åœ burned out 5. Stator wire åœ Open circuit 1 Repair the power supply 2. Repair or replace the switch 3. Replace the brush or adjust the return position 4. Exchange the stator coil in the cabinet 5. If the outlet can be welded after use, otherwise rewound. 2, the electric pump suction after the abnormal sound and does not rotate or turn very slowly 1. switch contacts burn out 2 machine maple stuck 3. debris at the inlet pipe 4. a small amount of armature short-circuit Or open circuit 5. Low supply voltage 1. Repair or replace the switch 2. Check the mechanical parts 3. Clean up debris 4. Repair or replace the armature 5. Adjust the power supply voltage 3, Armature short-circuit breaking 2. Commutator surface is not clean 1. Repair armature 2. Clear debris and make the commutator surface clean 4, the motor rotates and the shaft does not turn 1. Coupling (universal joint) damage 2. Shaft thread break off 1. Replace the coupling (universal joint) 2. Change the shaft or short axis
