Information

Wall mounted air-conditioning motor is one of the indispensable equipment in production and manufacturing. In order to ensure the normal operation of the motor, in addition to the normal use according to the operating procedures and the normal monitoring and maintenance during operation, regular inspections should also be carried out. Motor maintenance work.

1、The meaning of daily maintenance of Wall mounted air-conditioning motor:

Whether our mechanical equipment can work normally, a very important part is whether the motor can work normally. Therefore, motor maintenance is also very important. Many people always do not pay attention to maintenance or do not know how to maintain it. When the motor has a problem, the motor can only be repaired. If it is repaired, it will cost money and delay work. I regret not doing good maintenance before. Maintenance is also a university question.

  1. How to maintain Wall mounted air-conditioning motor:   

Normally, the maintenance of wall mounted air-conditioning motor should pay attention to: keep the motor clean and free of dust; always check the appearance of the motor to see if there are parts misaligned; often check the bearing for replacement or refueling, and also check the inlet terminal.

If it requires careful maintenance, the wall mounted air-conditioning motor is in continuous operation. Daily maintenance is very important: When the motor is working, pay attention to the working environment and do not be in a state of too turbulence to prevent the motor from being damaged. Or reduce the service life. Visual inspection is also required to check whether the fan works normally, whether there is abnormal vibration, whether the coupling connection is reliable, whether the base is fixed tightly, whether the bearing is working normally (listen to the sound), whether the temperature is normal (infrared thermometer), and whether the current Normal (clamp-type ammeter). In addition, the carbon brush and slip ring must be checked for winding motors. If there is an abnormality in one aspect, it is necessary to repair the motor as soon as possible, otherwise, after the situation becomes serious, you can't handle it.

The function of the motor protector is to fully protect the motor. It will give an alarm when the motor is overloaded, lacking phase, locked rotor, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, and stator and rotor eccentricity. Or protective device.

  1. Wall mounted air-conditioning motor protection knowledge Due to the continuous development of insulation technology, the design of motors requires both an increase in output and a reduction in volume, so that the thermal capacity of the new motor is getting smaller and the overload capacity is getting weaker; and due to the increase in the degree of production automation, it is required The motor often runs in a variety of ways such as frequent starting, braking, forward and reverse rotation and variable load, which puts forward higher requirements on the motor protection device. In addition, the motor has a wider range of applications, often working in extremely harsh environments, such as humidity, high temperature, dust, and corrosion. All of these make the motor more prone to damage, especially the highest frequency of faults such as overload, short circuit, phase loss, and bore sweeping.

Wall mounted air-conditioning motor protector has been developed from mechanical type to electronic type and intelligent type. It can directly display the current, voltage, temperature and other parameters of the motor. It has high sensitivity, high reliability, multiple functions, convenient debugging and protection action. The types of failures are clear at a glance, which not only reduces the damage of the motor, but also greatly facilitates the judgment of the failure, which is beneficial to the troubleshooting of the production site and shortens the recovery time. In addition, the use of air gap magnetic field for motor eccentricity detection technology makes it possible to monitor the wear status of Wall mounted air-conditioning motor online. The curve shows the change trend of the motor eccentricity, which can detect bearing wear and go inner circle, go outer circle, etc. Faults should be detected and dealt with early to avoid the occurrence of sweeping accidents.

Reasonable selection of the wall mounted air-conditioning motor protection device can not only give full play to the overload capacity of the motor, but also avoid damage, thereby improving the reliability of the electric drive system and the continuity of production. The specific function selection should comprehensively consider the value of the motor itself, the load type, the use environment, the importance of the main equipment, and whether the withdrawal will cause a serious impact on the production system and other factors, and strive to be economically reasonable.
