Causes and maintenance and repair methods of high and low temperature test chamber without cooling

Causes and maintenance and repair methods of high and low temperature test chamber

We often use high and low temperature test chambers, it will inevitably fail, so high and low temperature test What is the cause of the box not cooling? What should I repair repair? There are about several reasons:

1, hardware failure. A hardware that may cause the high and low temperature test chamber is not refrigerated is a refrigerating element such as a compressor, a solenoid valve. Then we can probably understand what hardware damage can be observed by listening and touching. Other refrigeration components failure users are not too good to master, please request a professional maintenance engineer to check analysis. In addition, the damage of the controller and the damage to the refrigeration system are also possible to cause a phenomenon that the high and low temperature test chamber does not cool the cooling.

There is also a hardware failure that will meet during the high and low temperature test chamber maintenance,
When the energy matching of high and low temperature test chamber is unreasonable, such as the heating power is installed, Damage to the heating element will directly lead to the cooling capacity and heat content, although there is a refrigeration amount, but is indeed offset by fierce heating and the amount of heat is high, and the temperature will seem to drop.

2, soft fault. The soft fault mainly refers to the controller failure of the high and low temperature test chamber, including internal parameters, controlling the control points IS control and output signals of the solenoid valve, etc., this fault user is not very good, please Maintenance engineer home check analysis.

3, system failure. The system failure refers to the initial design of the refrigeration system of the high and low temperature test chamber, including the high and low temperature test chamber caused by the leakage of the refrigerant, and the refrigerant leak is often shake during transportation and high and low temperature test chamber. Or the refrigeration copper tube welding process is caused, so it cannot be just add snow, but to find the source of the leak, we can have the effect of treating the standard.
