Do you know the maintenance of special motors for air compressors!
1. The use conditions of the special motor for air compressor accessories (the export machine varies with the country where it is located)
Ambient temperature <40 degrees above sea level <1000 meters
2. Operation of dedicated motor for air compressor accessories
1) The motor should be properly grounded. The grounding wire of the special motor for air compressor is generally led to the inside of the electric cabinet and connected to the cabinet. Only the user's grounding wire needs to be reliably connected to this point.
2) There is a clear mark on the lead-out line of the special motor for air compressor.
3) The connection method of the special motor for air compressor is clearly marked on the nameplate.
4) When the voltage and frequency of the dedicated motor for air compressor maintain the values specified on the nameplate, the motor can run continuously at the power of the rated power multiplied by the coefficient. When the frequency deviation of the power supply exceeds 1% of the nameplate value or the voltage under/over voltage exceeds 10%, the motor cannot guarantee continuous output of this power.
5) When the three-phase unbalance of the power supply does not exceed 1%, the air compressor special motor can operate well.
6) The electrical cabinet of the air compressor is generally equipped with a thermal relay as a motor overload protection element.
7) There should be no intermittent or abnormal sound or vibration when the motor is running with no load or 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 obstructed by dust, fibers, etc.
2) When the thermal relay is activated, the source of the fault should be checked and the fault can be removed before it can be put into operation.
3) It should be ensured that the bearings are well lubricated during the operation of the motor. Generally, the motor runs for about 2000 hours, that is, the grease should be added or replaced (the closed bearing does not need to be replaced during the service life). When the bearing is found to be overheated or the grease is deteriorated during operation, the grease should be replaced in time, and the bearing and cover should be cleaned. Add grease after the groove. The grade of the grease varies with the motor.
4) When the life of the bearing is over, the vibration and noise of the motor will increase significantly, and the bearing should be replaced at this time.
5) After the motor fails, it is recommended that the user contact the company or agent.
Because each air compressor manufacturer has differences in production batches and models, when the machine has problems or needs maintenance and inspection, you should contact the air compressor manufacturer so that you can easily solve the air compressor in production. Problems encountered in the process.
