The maintenance and service of ultra-low temperature refrigerators is particularly important for extending their lifespan and normal use. If the temperature control is inaccurate, it often results in damage to the saved objects, which will have a great impact on the experimental results, thus affecting the normal conduct of research work. 1. Clean once a month to ensure its cleanliness Use a dry cloth to remove small amounts of dust from the inside and outside of the refrigerator. If the refrigerator is dirty, use a neutral detergent. Rinse thoroughly with purified water after cleaning. However, do not flush the interior and top of the refrigerator. Doing so can damage the insulation and cause malfunctions. Lubricants are not required for compressors and other mechanical parts. Clean the fan on the back of the compressor with care. After the cleaning, perform a safety check to ensure that the refrigerator plug is plugged in, and that there is no false heat; ensure that the plug does not have unusual heat; and ensure that the power cord and distribution wires on the back of the refrigerator are not broken or nicked. 2, alarms start the alarm When an alarm is activated by an alarm, it is usually checked in the following ways. First, check if there is a problem with the power supply or if the plug is pulled out of the socket; Second, check whether the internal thermometer is out of the proper range. In this case, placing the item in the refrigerator will raise the temperature of the refrigerator and trigger the alarm. Third, check if there are too many disposable articles. 3, refrigerator cooling is not sufficient Check whether there is frost on the surface of the evaporator; if the refrigerator door is switched too frequently; if the back of the refrigerator is in contact with the wall; whether to put too many items. 4, excessive noise in the refrigerator Check if the bottom plate is firm; if the refrigerator is stable; if it is unstable, adjust the movable screws so that the four corners are firmly supported on the bottom plate; if there is any object coming into contact with the back of the refrigerator. If the cooling effect is poor, the refrigerator does not shut down, the heat pipe is not hot, and the evaporator has little airflow sound. This is because slow leakage causes a serious defect in the refrigerant. In the actual use of the process, there will be many other problems, the solution of such problems need to continue to accumulate experience to eliminate obstacles, so that the ultra-low temperature refrigerator to achieve the best working condition.
