With the strong arrival of the cold wave, most parts of our country ushered in a significant cooling. In such extreme weather conditions, not only people's lives will be affected, but even our environmental testing equipment may face serious challenges. To ensure the proper operation and longevity of these devices, experts recommend a series of special care and maintenance measures.
First of all, frost protection is crucial. During the cold wave, the ambient temperature drops sharply, and the equipment may freeze, solidify, and precipitate crystals. Therefore, for equipment in use, it is essential to ensure that it is kept within the proper temperature range. Some devices may require the electrically assisted heating function of the circulating water tower or water chiller to prevent the water temperature from getting too low. At the same time, the circulating water tower equipped with a cooling fan regulator can further control the temperature of the equipment by adjusting the opening temperature of the cooling fan. In addition, lowering the freezing point of circulating cooling water is also an effective means of antifreeze, which can be achieved by adding an appropriate amount of ethylene glycol or antifreeze to the circulating waterway, generally adding about 35% of the amount.
For equipment that is not in use for the time being, antifreeze measures should not be ignored either. Experts recommend closing the inlet and outlet valves of the cooling tower or chiller condenser and opening the open water valve to drain the water to prevent freezing inside the equipment.
Secondly, insulation is equally important. Wrapping the equipment with insulation material can effectively prevent the equipment from being affected by low temperatures. At the same time, it is necessary to regularly check the integrity of the insulation material, and replace it in time once it is found to be damaged.
In addition to freeze protection and heat preservation, dehumidification is also a key part of equipment maintenance during cold spells. Due to cold spells that can be accompanied by high humidity weather, the device is susceptible to moisture. Therefore, it is necessary to open the equipment regularly for ventilation and reduce the internal humidity. At the same time, it is also important to keep the equipment clean, and regular cleaning of the equipment can effectively prevent dust and dirt from affecting the normal operation of the equipment.
During the cold wave, it is also necessary to intensify the inspection of equipment. Regularly check whether the functions of the equipment are normal, such as meters, controllers, etc. Once an abnormality is found, it should be dealt with immediately to prevent the problem from expanding and affecting the overall operation of the equipment.
Finally, it is also important to keep a record of the care and maintenance of the equipment. This can not only facilitate subsequent tracking and management, but also provide a strong guarantee for the long-term stable operation of the equipment.
In short, when the cold wave hits, we need to take special care of the environmental test equipment. By taking the above series of measures, we can ensure that the equipment can still operate stably under extreme weather conditions, and provide strong support for China's scientific research and production work.
