1 、 no response after power on. Most are the power plug, the power outlet line and the motor winding short circuit.
2, difficult to start or can not start, and accompanied by “buzzing” sound. Maintenance when used by a small bamboo running direction to quickly toggle fan, if the Baotou Benz motor parts to work quickly, that is the starting capacitor or the starting winding is damaged, should be replaced with the same capacity capacitor or repair the startup winding; if the motor card, multi motor and pump head mechanical faults, such as the damage of bearing, impeller card the dead.
3, the motor can operate, but the speed is slow, and the casing overheating, burning odor. Most are caused by short circuit of motor winding, motor should be opened, depending on the damage by repair welding, jumper, isolation, rewind and other measures.
4 、 noise and vibration during operation. The majority is in line with the Baotou North Benz accessories bearing bearing and the casing damage or improper, need to open the motor to check if the bearing is damaged, should be replaced; if the bearing running round, the pump shell with the surface of the flower processing; if the bearing running in the round, can wear on the motor shaft position with flower processing, wear seriously, by turning method after welding repair.
Sprinkler pump head section
1, northern Baotou Benz accessories motor normal operation, but less water or no water. This situation should first check the sprinkler pump seal, check should unplug the power plug, hand to block the water outlet, the pump filled with water, hold in the mouth of the export tried to blow in the observation, the pump head is Water Leakage, Water Leakage point also is the seal damage. The common fault parts are suction pad, water outlet pad and impeller cover, which should be replaced during maintenance. If there is no full water phenomenon, most of the impeller damage, water absorption room and water chamber between the water, corrosion, wear, pump head, water block, grinding, impeller and pump housing gap increases, etc., should replace the impeller and pump shell. Replacement: wheel should pay attention to the elimination of residual copper in vane pumps, so as to avoid further damage to the new impeller.
2 、 the shell is live. Most of the water seal is damaged, the water through the motor shaft into the motor, resulting in deterioration of the insulation performance of the motor, you can replace the water seal, drying motor and other methods of repair. Need to pay attention to, because the pump for long-term contact with water and outdoor work, easy to damp and cause deterioration of insulation performance, in order to ensure personal safety, electric sprinkler truck self suction pump should be reliable grounding.
