Some precautions for industrial cold air fans during shutdown

　　In winter, our industrial air coolers are generally out of service for a long time. Keruilai reminds everyone that when the industrial air cooler is out of service, you should pay attention to the following matters to prevent damage and failure of the air cooler.

　　1. The industrial air cooler has stopped running for a long time, and some parts are exposed to the air, or even to the sun and rain, and the appearance is prone to rust. When used again, it will not only affect the appearance of the air cooler, but also the operating speed of the air cooler will be affected to a certain extent. In this regard, we need to prevent protection. A common anti-rust method is to apply anti-rust agent on parts that are prone to rust. Of course, it is necessary to reduce the exposure of industrial air coolers to sunlight and not to leave them in humid air for a long time.

　　2. In the northern region, the temperature is low in winter. If the workshop where the industrial air cooler is installed or the environment in which the air cooler operates is not good, attention must be paid to the antifreeze problem of the air cooler. In winter, if the air cooler is not used for a long time and the temperature is below zero, it must be Check the bearing box and drain the cooling water inside. Otherwise, if the temperature drops below zero, the cooling water will freeze and expand in volume, which will cause the bearing box to crack.

　　3. The maintenance of electrical components is also very important, especially the motor, which is an important power organ of the industrial air cooler. In coastal cities and when the rainy season comes, the humid air will cause the motor and other electrical components to become damp and affect their operation. If left untreated for a long time, the working ability of the air cooler will be lost. Therefore, when the industrial air cooler is not used for a long time, moisture-proof work must be done. The workshop and operating environment need to be ventilated and exhausted. Windows must not be opened on walls with moist air and in the upwind direction.

　　4. If the industrial air cooler is not used for a long time, the material of the main shaft determines that if it is in a static state for a long time, it will be very easy to deform or even bend. When it is used again, the main shaft will deviate from the running track, causing the wind direction to be unstable and the wind force to be reduced, resulting in cold wind. The impact of machine operation quality. Therefore, when the industrial air cooler is not in use, it is necessary to run the main shaft and other components at regular intervals and let the rotor rotate 180°, so that the main shaft will not be deformed or even bent due to long-term inactivity.

　　In addition to the above situations that require our special attention, we cannot relax other aspects of maintenance of industrial air coolers. Perform regular maintenance on them and develop a complete maintenance and upkeep plan so that when you start the air cooler again, its operating quality will not be affected and the service life of the air cooler can be extended.
