Auman's top four and eight dump truck air conditioners will experience fluorine leakage after a long period of non-use. At the same time, they will lead to poor air conditioning and refrigeration. However, the first four rear eight dump truck air conditioning systems are installed in the work area. In a very hidden location, it is difficult to check the location of the leakage point when performing leak detection. It is also inconvenient to carry out maintenance. In such a situation, the driver will have to repeatedly The addition of fluorine does not only increase the cost but also pollutes the environment. Then what are the ways in which the air-conditioning refrigeration system can detect leaks?
1. The use of electronic leak detection is also a new detection method that has only recently emerged in recent years. When it is used to detect leaks in front of the Auman four dump trucks, it only needs to use the detection probes against those that may leak. The position moves back and forth. If the leak detection device has a warning sound, then it proves that there is a leak in this position. However, because electronic leak detection is easier when it is working, it will be detected by some external environment. For example, in the case of exhaust gas or odor, etc., it may affect the leak detection. The device cannot detect the correct leak.
2. The use of visual inspection is very simple and it is also a relatively primitive method of detection. However, the bigger problem is that the leakage effect of such a detection method is extremely low, and those smaller leakage points cannot be found, except that the leakage point is relatively large.
3, leak detection method is also more often used in condensers, evaporators, compressors and other components, the detection method is to fill the components into the appropriate compressed air, and then placed in between 50 degrees Celsius The presence of air bubbles within the water temperature is observed. The purpose of using this water temperature is to be able to reduce the surface tension of the water. If the temperature of the water is relatively low, the surface tension will be greater, and those smaller leakage points. It cannot be detected.
4, using soapy water to carry out Auman before the fourth and eighth tipper leak detection, in fact, is now the roadside vehicle maintenance point is a very common leak detection method, you can not make the air conditioning system when the big dismantling, use non-find Sleeping smeared on various parts of the air-conditioning system, the bubbling position was observed as a leak. However, because some leaked points are more subtle, the internal space of the Auman's front and rear eight air conditioning units is relatively narrow. There is no way to use the arm to reach the relevant position and apply soapy water. Some parts will be more to block the line of sight, even if there is a leak point is more difficult to see. The lines in the workbench are more complex, and the use of soapy water leak detection may even result in short circuiting of the dump truck's wires.
Radius Cutting Machine is designed to perform saddle cuts on plastic pipes made of HDPE, PP, PVDF. Radius Saw is the ideal cutting device to match hdpe Saddle Fusion welding machine. Radius cutter performs precise radial cuts and allows a fast configuration of the cutting radius before reducing tee fabrication.
