The configuration of high temperature chillers from different manufacturers is different. The configuration of Wuxi Guanya (LNEYA) high-temperature refrigerators is all purchased by the brand, using a fully enclosed pipeline system, but some manufacturers of high-temperature refrigerators often need to understand the common faults, such as high-temperature refrigerator internal leakage faults, then internal leakage How to solve the problem?
The internal leakage of the high-temperature refrigerator needs to be checked first, and the high-temperature refrigerator refrigeration pipeline is filled with nitrogen. Then use a stethoscope to check the interior. When you hear a leak in a certain area, mark it. Carefully pry open the metal plate at that place, check the leak point of the pipe with thick soapy water, repair by repair welding or gluing, fill the foaming agent, fill the mouth with a larger metal plate, and glue the four sides. . This method is incapable of causing micro-leakage in the refrigeration system, and is likely to cause false detection or missed detection.
After determining the evaporator leak, the high temperature refrigerator performs replacement repair with a finished evaporator that can be loaded into the inner evaporator cavity. Connect the new evaporator of the high temperature chiller to the original refrigeration line and replace the new capillary and dryer. The disadvantage of this method is the high cost, which is powerless when encountering evaporators with special shapes or multi-door machines and leaks in the refrigeration tubes.
The copper coiling method is a suitable repair method for leaking any type of high temperature refrigerator. Generally, the size of the purchased copper pipe is calculated first, and the shape and length of the copper pipe are determined according to the size of the inner casing. During the overhaul, the back plate of the high-temperature refrigerator should be raked to excavate the original foaming material of the high-temperature refrigerator. After exposing the evaporation tube, it is filled with nitrogen to check for leaks. Pay special attention to each connection solder joint when detecting leaks. This repair method is suitable for the case where the refrigeration system has a connector on the back, and is not suitable for the occurrence of internal leakage in the refrigeration pipe having a leak point at a deeper level. After the leak is detected, repair welding or repair with a glue pool, then re-foam and make up the back plate.
Once it is found that there is an internal leakage fault in the high temperature refrigerator, it is recommended that the user solve the faults in a timely and effective manner to avoid affecting the project.
