Electrical Induction Iron Motors Frame

Compressor excessive current when the motor running, the cause analysis and elimination method
A, reason analysis Generally considered A refrigerator at work current value, more than normal working current 1.1 1.2 A, which is to think too much electricity. Here's why: 1, refrigerators and other high-power electrical equipment on the same power supply cord. 2, the power of the input voltage is too low, lower than allowed work voltage on duty, starting current is too large. 3, refrigeration systems affected by external factors, such as condenser clingy wall, there is too much dirt on tube, natural air flow effect is poor, the hot air send out not to go out; Or refrigerator near the heat source too, the refrigerator to store too much hot food, these factors will make the condensing pressure, cause the compressor start is difficult, the motor current is too large. 4, compressor internal assembly is not in conformity with the technical requirements, cause movement friction is too large, ac synchronous motor lead to electric reach rated speed, or even halt. Motor current is too large. 5, all of a sudden power failure, suddenly calls, time interval is short, high and low pressure in the system haven't balance, cause big start difficult, current is too large. 6, refrigerator system refrigerant leakage, temperature to drop, motor operation, cause too much electricity. 7, start relay failure, the thermal protector lost ability, cause too much electricity. Second, the elimination method 1, shall set up special diesel generators prices line power supply. 2, install the coupling voltage regulator, voltage regulator to the electrical ratings. 3, the refrigerator should be put in the place where the air circulation. 4, cut casing, reassemble the parts according to the technical standard. 5, when a sudden power failure found, shall be immediately disconnected refrigerator power head, when the power is www.dongfeng-motor.com on, then use the refrigerator. 6, by check, confirm the refrigerant in the system has been leaking, shall promptly repair and add freon. 7, start relay failure, should be timely repair or replacement.
