1. Conditions for use of special motors for air compressor accessories (exported machines vary depending on the country where they are located)
Ambient temperature <40 degrees Altitude <1000 meters
2. Special motor operation for air compressor accessories
1) The motor should be properly grounded. The grounding wire of the special motor of the air compressor is generally led to the inside of the electrical cabinet and connected to the cabinet body. You only need to reliably connect the user's grounding wire to this point.
2) There are clear signs on the lead-out line of the special motor of the air compressor.
3) The connection method of the special motor of the air compressor is clearly marked on the nameplate.
4) When the voltage and frequency of the special motor for air compressors maintain the values specified on the nameplate, the motor can run continuously at the rated power multiplied by the coefficient. When the frequency deviation of the power supply exceeds the nameplate value by 1% or the voltage under/overvoltage exceeds 10%, the motor cannot guarantee continuous output of this power.
5) When the three-phase imbalance of the power supply does not exceed 1%, the special motor for the air compressor can operate well.
6) The electrical cabinet of the air compressor is generally equipped with a thermal relay as a motor overload protection component.
7) There should be no intermittent or abnormal sound or vibration when the motor is running without load or with load.
3. Air compressor repair-special motor repair:
1) The operating environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be blocked by dust, fibers, etc.
2) When the thermal relay operates, the source of the fault should be checked and the fault can be eliminated before it can be put into operation.
3) Ensure that the bearings are well lubricated during motor operation. Generally, the grease should be replenished or replaced after the motor runs for about 2,000 hours (sealed bearings do not need to be replaced during their service life). If the bearing is found to be overheated or the grease has deteriorated during operation, the grease should be replaced in time. After cleaning the bearings and covers Add grease after the groove. The grade of grease varies with the motor.
4) When the bearing life ends, the vibration and noise of the motor during operation will increase significantly, and the bearings should be replaced at this time.
5) After the motor fails, it is recommended that the user contact the company or agent.
