Daily maintenance of low temperature refrigerators :
1, to ensure that the ambient temperature. The working temperature of the ultra-low temperature refrigerator must be below 30 °C and the surrounding area is well ventilated. Excessive temperature or poor ventilation can easily cause damage to the equipment due to overload operation.
2 , clean once a month to ensure its cleanliness
Use a dry cloth to remove a small amount of dust from the inside and outside of the refrigerator and the accessories. After the cleaning is completed, carry out safety inspection to ensure that the refrigerator plug is plugged in, not to be connected. Make sure that the plug is not dirty, use a neutral detergent, and then rinse thoroughly with pure water. However, do not flush the water inside and outside the refrigerator, otherwise it will damage the insulation and cause malfunction. Lubricants are not required for compressors and other mechanical parts. Abnormal heat after cleaning the compressor; ensure that the power and distribution wires on the back of the refrigerator are not cracked or scored.
3 , ultra-low temperature refrigerator cooling is not enough
Check if there is frost on the surface of the evaporator; if the refrigerator door is over-switched; if the back of the refrigerator touches the wall; if too many items are placed.
4, regular cleaning of the heat filter (every two months). The filter is not cleaned for a long time, and the dust blocks the mesh, resulting in poor heat dissipation, resulting in damage to the heat-dissipating motor and damage to the compressor. Please check the instruction manual for the cleaning method.
5 , ultra-low temperature refrigerator is too noisy
Check if the bottom plate is strong; 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 any objects touch the back of the refrigerator. If the cooling effect is poor, the refrigerator does not stop, the heat pipe is not hot, and the evaporator has a small airflow sound. These are caused by the serious leakage of the refrigerant due to slow leakage. In the actual use process, there will be many other problems. The solution to such problems requires continuous accumulation of experience to eliminate obstacles and make the ultra-low temperature refrigerator reach the best working condition.
6, regular cleaning of the refrigerator door seal at the ice. The door seal is not strict, and the heat preservation effect is seriously degraded, which may cause damage to the compressor due to long-term overload operation.
7 , the alarm starts the alarm
When an alarm is activated to trigger an alarm, it can usually be checked by the following aspects.
First, check if there is a problem with the power supply or if the plug is pulled out of the socket;
Second, check if the internal thermometer is out of the proper range. In this case, placing the item will warm the refrigerator and trigger the alarm;
Third, check if there are too many items for one time.

Special life jacket, also known as life jacket, is a kind of life jacket, designed like a vest, made of nylon fabric or neoprene (NEOPRENE). Buoyancy material or inflatable material. Reflective material, etc. The general service life is 5-7 years, it is a ship And one of the Life-saving Equipment on the plane. It is generally vest type, made of foam plastic or cork. It has enough buoyancy to wear on the body, so that the head of the drowning person can come out of the water.
