Xiao Bian believes that the advantages and disadvantages of high and low temperature test chambers, the most important thing is to distinguish the good and bad of the compressor unit, to see if it meets the performance of the equipment you bought. Its good or bad also directly affects the service life of the test equipment and the test results are correct. We can make a simple judgment from these aspects: appearance, production date, sound, surface temperature of the compressor, etc.
First of all, the compressor in a brand new high and low temperature test chamber is generally very smooth, and the color is bright and bright, and the input and output tube welds are directly welded to the evaporator. If it is re-welded, Generally there will be polished marks.
Secondly, there are nameplates on the new compressors, which are marked with the model number, number, date of manufacture, power size, etc., which we can check one by one.
Then, as the compressor starts to rotate, as the running time increases, the compressor should emit a clear, uniform, smooth running sound, and the sound will gradually decrease. When the machine is stopped, the compressor will not emit an abnormal sound.
Finally, when the compressor of the high and low temperature test chamber is in operation, we can also touch the outer casing with the back of the hand, and the outer casing will not be very hot. If the above checks are not met or if one does not meet the performance criteria, you can directly ask the manufacturer of the test equipment what the problem is and ask for a solution.
