Cryogenic refrigerator using operating points for attention

by:CBFI     2020-09-29
In order to guarantee the ultra-low temperature freezer better use and extend its service life, ultra-low temperature freezer factory according to 12 years of experience in research and development of cryogenic refrigerator and production, sums up some cryogenic refrigerator using operating precautions:

1, please give special cryogenic refrigerator with an over current, the leakage protection switch, and can't share the same power socket with other equipment;

2, ultra-low temperature freezer should be placed in a ventilated place, running environment temperature should not exceed 30 ℃. If you can't guarantee the environmental temperature, when the temperature exceeds 30 ℃, please put the refrigerator temperature is set in - Around 75 ℃;

3, when you put items from the ultra-low temperature freezer, please wear the freeze protection gloves, in order to prevent frostbite;

4, please do not use glass ( And other low temperature resistant material) Containers for need frozen items, in case the vessel crack up;

5, are strictly forbidden in the ultra-low temperature freezer in a volatile, flammable, explosive and other dangerous characteristics of goods;

6, the appearance of the ultra-low temperature freezer cannot use water wash directly, such easy to cause the refrigerator leakage;

7, please do not one-time put more than 10 kg is not frozen items, if you need to put in more than 10 kg, partial successive must add, when the temperature of the first batch of goods can set temperature is reached in the next batch, each batch amount can't more than 10 kg, add to the amount of not more than 150 kg, otherwise the fridge run overload for a long time, can produce adverse effect to the compressor, even damage the compressor;

8, ultra-low temperature freezer display temperature is the center of the tank temperature, temperature of local space is likely to differ & plusmn; 5 ℃, usually after the refrigerator temperature stability, the temperature a little higher, the lower temperature;

9, according to the working environment is different, generally every three months to clean the condenser fin and filter, if the environment is particularly bad, should be once a month. Clean, dry finned available hard brush to brush up and down, to get rid of dirt, larger gap of or with pressure air ( Or nitrogen about 0. 5MPa) Blows away the dust.

10, please do not cut holes in the box body, so as not to drill broken close to the cooling of the outer wall of the pipeline, such as have a very special case, please consult the manufacturer;

11, if the cryogenic refrigerator can not meet the set temperature for a long time, please do not hesitate to contact the manufacturer. Without consent by the our factory maintenance personnel for repair, the manufacturer shall have the right to refuse to repair, by using the party responsible for the resulting loss.

12, when the temperature is lower than the set value 0. 5 ℃, the machine stop into the insulation state, when the temperature is higher than the set value 0. 5 ℃ to run, run during the temperature will rise 1 ~ 3 ℃, belongs to the normal situation.

13, please do not modify temperature except & lsquo; The refrigeration temperature & rsquo; The other parameters (beyond Under normal condition has been lock) , so as not to cause a system exception.
