Repair and maintenance of AC condenser fan motor
The electric heating pipes of the AC condenser fan motor and air cooler are vulnerable parts. Fan motors that operate for a long time in high-temperature environments may malfunction and be damaged. If the temperature of the cold storage is very important, it is necessary to order some vulnerable parts for timely maintenance.
The environmental temperature issue of the AC condenser fan motor. AC condenser fan motors are usually installed on the roof of outdoor buildings. In the high temperature environment of summer, the temperature of the condenser itself is very high, which will increase the working pressure of the equipment. If the weather is hot, a cool shed can be added to the condensation water on the roof to block sunlight and lower the temperature of the condenser, thereby reducing the pressure on the machine, protecting equipment, and ensuring the temperature of the cold storage. Of course, if the unit capacity is sufficient to ensure storage temperature, there is no need to build a greenhouse.
The electric heating tube of the air cooler also requires spare parts for greater safety. The installation of refrigeration system equipment and refrigerant pipelines, as well as the overall design and daily use of cold storage, must be strictly carried out in accordance with regulations. Any irregular design, installation, use, or maintenance can lead to poor operation of the refrigeration system, even causing malfunctions and machine damage.
Of course, no matter which type of motor we use, we need to repair and maintain the equipment. Today, we will learn how to repair and maintain the AC condenser fan motor!
During the operation of the AC condenser fan motor, it was found that there was an abnormal sound from the fan, causing severe heating of the motor, electrification of the casing, tripping of the switch, and inability to start. It should be immediately closed for inspection. To ensure safety, maintenance is not allowed during fan operation. After maintenance, a trial run of about 5 minutes should be conducted to confirm that there are no abnormalities before starting the operation.
2. The AC condenser fan motor should be stored in a dry environment to prevent moisture from the motor. When storing AC cooling fans in the open air, protective measures should be taken. During storage and transportation, avoid the impact of AC cooling fans to avoid damage to the fans.
3. The AC condenser fan motor can only operate under normal conditions. At the same time, it is necessary to ensure that the capacity of the power supply equipment is sufficient, the voltage is stable, and phase free operation is strictly prohibited.
4. The AC condenser fan motor should always be kept clean in the usage environment, the surface of the fan should be kept clean, there should be no debris at the inlet and outlet, and there should be dust and other debris inside the fan and pipeline. Regularly clean.
5. According to the working environment conditions, lubricating grease should be supplemented or replaced from time to time. During its service life, there is no need to replace the lubricating grease on the enclosed bearings of the AC condenser fan motor. There are corresponding requirements to seal the bearings and motor bearings, and professional lubricating grease should be used to fill the inner and outer rings of the bearings, and it is strictly prohibited to operate without oil.
