Causes of refrigerant leakage in high and low temperature test chambers

Many manufacturers have mentioned some repair methods for refrigerant leaks in high and low temperature test chambers, but few people mention the causes of refrigerant leakage. Only know the root causes of leaks in the refrigeration system can be a temporary solution to the problem, followed by Wuhan Ande. Letter Detection Equipment Co., Ltd. to do a detailed explanation for everyone!

Brief introduction of high and low temperature test box: From the name, it is easy to see that it is a box type equipment that provides high temperature and low temperature, generally used for high and low temperature test of electronic products, auto parts, electrical accessories, hardware, plastic products, etc. /T 10592-1989 National standard design.

Refrigerant Profile: Refrigerant is the blood of various types of refrigeration equipment such as high and low temperature test chambers, constant temperature and humidity test chambers, and cold and heat shock test chambers, etc., and the refrigeration cycle is formed by four major parts of refrigeration—compressors, condensers, capillaries, and evaporators. A chemical substance that continuously evaporates and condenses to form a heat transfer. Normally, if the refrigeration system does not leak, it can be used for a long period of time.

The reason for the leak:
1. System piping: Brass welding is not firm at the factory, cracks, trachoma, loose, fracture, etc.
2 screw connection: Loose seal with screw
3、Rubber seal: Including aging, cracking and deformation caused by long-term use of all kinds of rubber seal rings and gaskets in refrigeration system
4, accessories problems: including compressors, solenoid valves, expansion valves, cut-off valves and other parts pressure is not strong, wear and so on
5. Fixed method: It is also the most common culprit that causes the refrigerator to leak. Therefore, it has to be mentioned that a good device has very strict requirements on the fixing methods of the various components of the refrigeration system. If the equipment suddenly shows noisy noise, The situation must focus on inspections to see if there are broken pieces of fixed pieces, loose screws, etc., in order to deal with the problem in time.

In the actual maintenance process, the maintenance engineer generally places the leakage on the pipeline welding of the refrigeration system. It is not even known that there are many reasons leading to the leakage of the refrigerant, resulting in repeated maintenance of a device, which seriously affects the normality of the high and low temperature chamber. Use, only the real cause of the refrigerant leak in the high and low temperature test chamber and the culprit, in order to truly achieve the effect of a permanent cure!
