The previous article said that if you want the motor to run stably, it is necessary to do daily maintenance, todayMori machineXiaobian continue to talk about how to avoidThree-phase asynchronous motorBurn it down. Of course, daily maintenance is still very important, if there is a problem to find technicians to repair, do not disassemble.
1.Check motor temperature
It is necessary to check the temperature of the bearing, stator, housing and other parts of the motor frequently, especially for those without voltage, current and frequency monitoring and without overload protectionThree-phase asynchronous motor. If the temperature rise is found to be too high, it should be stopped immediately for inspection; In addition, the rolling body of the bearing, raceway surface, bearing clearance, etc., need to be regularly checked, and any abnormality found must be replaced after operation.
2.Viewing machine
Observe whether the motor vibration, noise and abnormal smell, vibration phenomenon, then the connected load part of the concentricity will become higher, increase the load of the motor, of course, we all know that after the load increases, the motor overload operation will burn. Noise and odor are the precursor of motor failure, and must be observed at any time.
3.Ensure that the boot device works properly
Generally speaking, the good and bad of the startup device are directly determinedThree-phase asynchronous motorWhether it can be started normally, according to past experience, most of the motors that have been burned are caused by the abnormal work of the starting equipment, such as the lack of phase start. Therefore, we should also pay attention to cleaning and fastening, such as contactor contacts if often not clean will cause the increase of electric shock resistance, causing the maintenance network heat burn contacts, and then burn the motor. Therefore, the starting equipment also needs to be cleaned regularly, and the electrical control cabinet should be set up in a dry, ventilated and easy to operate position.
