The inspection of the production of high and low temperature and humidity test chambers is the key

The production of high and low temperature test chamber with the growth of time, some parts may age, if not replaced in time maintenance, may make the production of high and low temperature test chamber can not work properly
.

Therefore, when there are some small problems in the production of high and low temperature test chambers, do not take it lightly, and often need to take professional diagnostic techniques to analyze the root cause
of the failure.

The refrigeration compressor for the production of high and low temperature test chambers is fully enclosed and is the driving force
for the refrigerant to maintain circulation.

If the suction exhaust pipe of the refrigeration compressor of the test chamber is ruptured or there is a small porous leak, it will cause the suction or exhaust volume of the system to be reduced, the refrigeration compressor operation time is extended, and the evaporator frost is incomplete or non-frosted, which cannot achieve the purpose of
refrigeration.

Therefore, in use, we must pay attention to the integrity
of the pipeline of the refrigeration system.

When the production of high and low temperature test chamber compressor suction exhaust pipe due to welding or collision and other reasons to produce a small leak, with soapy water inspection is not easy to find, can be used to immersion method for inspection
.

The specific method is: the high and low pipelines of the compressor are blocked, the nitrogen test pipe is connected to the process pipe to inflate, and then the compressor is completely immersed in water, carefully observe whether there are blisters, if there are blisters, it means leakage
.

The compressor that is immersed in water to find out the leak place needs to be re-welded to make up for the leak, and the drying treatment can be reused
for more than 4 hours.

The refrigeration system is a very important part of the production of high and low temperature test chambers, so we must pay attention to its maintenance and maintenance, and we cannot wait until there is a problem in the production of high and low temperature test
chambers.
