The AC condenser fan motor and the electric heating tube of the air cooler are wearing parts. Fan motors that run for a long time in a high temperature environment may fail and be damaged. If the temperature of the refrigerator is very important, some wearing parts must be ordered to facilitate timely maintenance.
Ambient temperature issue with AC condenser fan motor. AC condenser fan motors are usually installed on the roof of outdoor buildings. In the high temperature environment in summer, the temperature of the condenser itself is very high, which will increase the working pressure of the equipment. If the weather is hot, you can add a pergola over the roof condensate to block sunlight and lower the temperature of the condenser, which reduces the pressure on the machine, protects the equipment, and ensures the temperature of the cold storage room. . Of course, if the unit capacity is sufficient to ensure storage temperature, there is no need to build a pergola.
The electric heating tube of the air cooler also needs spare parts for more safety. The installation of refrigeration system equipment and refrigerant piping, even the overall design of the cold storage and the daily use of the cold storage must be carried out in strict accordance with the specifications. Any irregular design, installation, use or maintenance will cause the refrigeration system to operate poorly, or even cause malfunctions and machine damage.
Of course, no matter what kind of electric motor we use, the equipment needs to be repaired and maintained. Today, we'll learn how to repair and maintain an AC condenser fan motor!
1. During the operation of the fan motor of the AC condenser, it was found that the fan had abnormal noise, the motor heated seriously, the shell was charged, the switch tripped, and it could not be started. It should be closed immediately for inspection. For safety reasons, maintenance is not allowed while the fan is running. After maintenance, a test run for about 5 minutes should be performed to confirm that there is no abnormality before starting the operation.
2. The
AC condenser fan motor should be stored in a dry environment to prevent the motor from getting wet. Take precautionary measures when storing AC cooling fans in the open air. During storage and transportation, the AC cooling fan should be avoided to avoid damage to the fan.
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 and tidy in the use environment, the surface of the fan should be kept clean, there should be no debris in the inlet and outlet, and there should be dust and other debris in the fan and pipe. Clean regularly.
5. According to the working environment conditions, the grease should be replenished or replaced from time to time. There is no need to change the grease of the enclosed bearing of the AC condenser fan motor during its service life. There are corresponding requirements so that the bearings and motor bearings can be sealed, and the inner and outer rings of the bearings should be filled with professional grease, and it is strictly forbidden to run without oil.
