Maintenance and upkeep of wall mounted air conditioning motors

Wall mounted air conditioning motors are one of the essential equipment in production and manufacturing. In order to ensure the normal operation of the motor, in addition to following the operating procedures and conducting normal monitoring and maintenance during operation, regular inspections should also be carried out. Motor maintenance work.

The meaning of daily maintenance for wall mounted air conditioning motors:

A very important part of whether our mechanical equipment can work properly is whether the motor can work properly. Therefore, the maintenance of the motor is also important. Many people always neglect maintenance or do not know how to maintain it. When there is a problem with the motor, only the motor can be repaired. If repaired, it will cost money and delay work. Unfortunately, maintenance was not done well before. Maintenance is also a university issue.

How to maintain the wall mounted air conditioning motor:

Under normal circumstances, attention should be paid to the maintenance of wall mounted air conditioning motors: keep the motors clean and dust-free; Always check the appearance of the motor to see if any parts are misaligned; Regularly check whether the bearings need to be replaced or refueled, and check the air inlet.

If careful maintenance is required, the wall mounted air conditioning motor will operate continuously. Daily maintenance is very important: When the motor is working, please pay attention to the working environment and avoid being in a turbulent state to avoid damaging the motor. Or shorten 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 firmly fixed, whether the bearing works normally (listen to the sound), and whether the temperature is normal. Normal (infrared thermometer), and whether the current is normal (clamp type Ammeter). In addition, it is necessary to check the winding motor of the carbon brush and slip ring. If there is an abnormality in one aspect, the motor must be repaired as soon as possible, otherwise, in severe cases, you will not be able to handle it.

The function of the motor protector is to completely protect the motor. When the motor is overloaded, out of phase, locked rotor, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, and stator and rotor eccentricity, it will issue an alarm. Or protective devices.

Protection knowledge of wall mounted air conditioning motor Due to the continuous development of insulation technology, the design of motor requires both increasing output and reducing volume. Therefore, the Heat capacity of new motor is getting smaller and smaller, and the overload capacity is also getting higher and higher. It has become increasingly weak and due to the improvement of production automation, it is necessary for the electric motor to operate in multiple ways, such as frequent starting, braking, forward and reverse rotation, and variable load, which puts higher requirements on the motor protection device. In addition, electric motors have a wide range of applications, typically operating in extremely harsh environments such as humidity, high temperature, dust, and corrosion. All of these make the motor more susceptible to damage, especially the highest frequency faults, such as overload, short circuit, phase loss, and hole scanning.

The wall mounted air conditioning motor protector has evolved from a mechanical type to an electronic 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, and convenient debugging and protection actions. The types of faults are clear at a glance, which not only reduces the damage to the motor, but also greatly facilitates the diagnosis of faults, is conducive to troubleshooting on the production site, and shortens the recovery time. In addition, by using air gap magnetic field for motor eccentricity detection technology, the wear status of wall mounted air conditioning motors can be monitored online. The curve shows the trend of the eccentricity of the motor, which can detect bearing wear and enter positions such as the inner and outer rings. Faults should be identified and dealt with early to avoid cleaning accidents.

Reasonable selection of wall mounted air conditioning motor protection devices can not only fully utilize the overload capacity of the motor, but also avoid damage, thereby improving the reliability of the electric drive system and production continuity. The selection of specific functions should comprehensively consider factors such as the value of the motor itself, load type, usage environment, the importance of main equipment, and whether the shutdown will have a serious impact on the production system, and strive to achieve economic rationality.
