1. Partial parts are exposed to the air, even sun and rain, the surface is prone to rust. Not only will the appearance of the air cooler be affected when it is used again, but the speed of the air cooler will be affected to a certain extent. This is a problem encountered by many users of air coolers. In fact, the way to avoid the rust of the air cooler is very simple. The common method is to apply rust inhibitor on the parts that are prone to rust. Of course, it is necessary to reduce the exposure of the air cooler to sunlight, and not to place it in humid air for a long time.

    2. In the northern region, the temperature is low in winter. If the cooling fan is installed in the workshop or the cooling fan is operating in a poor environment, you must pay attention to the antifreeze problem of the cooler. If the cooler is not used for a long time in winter, the temperature is below zero. Check the bearing box and clean the cooling water inside. Otherwise, the temperature will drop below zero, the cooling water will freeze and shrink in volume, which will cause cracks in the bearing box.

    3. The maintenance of electrical components is also very important, especially the motor, which is an important power organ of the air cooler. In coastal cities and the rainy season, the air will be humid, which will cause the motor and other electrical components to be damp and affect their operation. Failure to deal with it will result in the loss of the ability of the air cooler. Therefore, moisture-proof work must be done when the air cooler is not used for a long time. The workshop and operating environment require ventilation and exhaust. The windows cannot be opened on the wall with humid air and upwind.

    4. The air cooler has not been used for a long time, and the material of the main shaft determines that if they are in a static state for a long time, they are very easy to deform, and even bend. When the main shaft deviates from the running track, the wind direction is unstable and the wind direction decreases, and the air cooler will be reduced. The impact of the quality of operation. Therefore, when the air cooler is not used, the main shaft and other components should be operated at regular intervals, and the rotor can be rotated by 180°, so that the main shaft will not be deformed or even bent due to long-term stationary. The long-term suspension of air coolers is not left to nothing, but needs time to pay attention to and maintain their well-being. In addition to the above-mentioned conditions that require our special attention, we cannot relax other aspects of the air cooler. Achieve regular maintenance for them, and develop a complete maintenance and maintenance plan, so that when the air cooler is restarted again, its operating quality will not be affected, so as to extend the life of the air cooler.
