The main problem of the micro electric self-priming pump q2)

,
(motor parts ） Without electricity after reaction. Most of the power cord, the power and the motor winding open lead cause.
( ） Disk boot or cannot be started, and with 'buzzing' sound. When maintenance is available in a small bamboo leaf direction quickly, if the machine up and running quickly, this is the start or start winding is damaged, replace or repair the same capacity of capacitor start winding; Card, if the motor is mainly and water pump electric machine, mechanical failure, such as bearing failure, impeller, jam, etc.
( ） The motor can run, but slowly, and chassis overheating, the smell of burning. In most of the damage caused by the motor winding short-circuit engine respectively welding should be open, jump line, isolation, weight and other measures to repair the wound.
( ） Running noise and vibration. Bearing damage or attached with the most appropriate case matching, motor disassemble, if should replace the bearing damage; If bearing 'outside running round', but with the pump shell carving surface treatment; If the bearing running circle 'can be engraved handle wear and tear, serious wear and tear, and adopt the first method after welding repair motor shaft rotational parts. Part of the

, pump ( ) The normal operation of the motor, but little or no water without water. This kind of circumstance should first check the sealing of pump, check should unplug the power cord, hand blocking water port, full of water pumps, in his first for export in the mouth is difficult to observe whether the pump head is leaking, leakage of the seal is in place. Failure of suction cups, export mat, impeller cover pad of the public area maintenance should be replaced. If there is no water phenomenon, mainly damage of impeller, suction chamber and etching chamber between the water inside the tank is full, the pump to keep each polishing, the clearance between the impeller and the pump increases, casing, etc. , should replace the impeller and pump casing. Replace the piece that should be paid attention to 16 residual copper pump, so as not to damage the new impeller.
( ) Persistently heckled him ever since. Most of the seal is damaged, water infiltration by motor, due to the motor insulation deterioration of motor shaft. Replaceable seal, drying, such as electrical appliances repair methods. It should be pointed out that due to the long contact with water pump and outdoor work, easy to be affected with damp be affected with damp insulation degradation, in order to ensure the personal safety, electric pump should be reliable grounding, winter should be used, such as water and warm cover measures to prevent freezing.
