Maintenance and maintenance of ultra-low temperature explosion-proof refrigerator

1. Refrigerator cooling is not sufficient

Check the evaporator surface for frost, whether the refrigerator door is switched too frequently, if the back of the refrigerator touches the wall, and if there are too many items on the surface.

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 on the accessories, if the refrigerator is too dirty, use a neutral detergent, clean and rinse completely with pure water. However, water can not be flushed inside and above the refrigerator, as this can damage insulation material and cause problems. Compressors and other mechanical parts do not require the use of lubricants. Care must be taken to clean the fans at the rear of the compressor. After cleaning, make sure the refrigerator plug is plugged in and not empty, make sure the plug is not abnormally hot, and make sure that the power and distribution wires on the back of the refrigerator do not break and nick.

3. The refrigerator is too noisy.

Check to see if the base plate is consolidated, the refrigerator is stable, if unstable, adjust the active screws so that the four corners are securely supported on the soleplate, and if there are any objects touching the back of the refrigerator.

If the cooling effect is poor, the refrigerator does not stop, the cooling tube is not hot, the evaporator has a small air flow sound, these are due to slow leakage caused by the refrigerant severe defects. In the actual use of the process, there will be many other problems, such problem stoic solution needs to accumulate experience to remove obstacles, so that ultra-low temperature explosion-proof refrigerator to achieve zui good working conditions.

4. Alarm stoa

When an alarm is activated by an alarm, it can usually be viewed through the following.

to see if there is a problem with the power supply or if the plug is pulled out of the socket;

Second, to see if the internal thermometer is out of the appropriate range, in which case the object will heat up the refrigerator and trigger the alarm;

Third, see if there are too many one-time items.
