The cause of the low pressure failure of the air-cooled cryogenic ice water machine

Air-cooled cryogenic ice water machine in the process of operation of low-pressure failure is very common, different fault situation solutions are not the same, so we have a comprehensive grasp of a variety of different fault solutions.
so what are the specific phenomena of low pressure failure of the freezer? Below is an introduction to several different phenomena and specific solutions.
many factors that cause low-pressure failure of cold water (frozen) machines, we will list only some of them today.
can be broadly divided into the following categories (from easy to difficult order) system leakage, system blockage, evaporator blockage.
: The "reset button" on the pressure controller needs to be pressed after each point of failure has been processed.
common low-pressure fault analysis and treatment are also applicable to other forms of refrigeration units.
Freezer common low-pressure fault analysis and treatment method failure one: the system has leakage refrigeration system connection pipe leakage points, such as welding problems, environmental corrosion problems, mechanical vibration caused by fracture problems, human factors and so on caused by low-voltage fault treatment.
This kind of problem is relatively simple to deal with, first of all, with leak detection (soap water, or cleaning water) or halogen leak detector can generally find the leak point, when found after welding equipment welding and do the necessary vacuum treatment, in accordance with the factory's provisions after filling refrigerant, the equipment can return to normal operation.
two: the system blocking refrigeration system blocking probably has these four reasons: a, debris blockage;
1, debris clogging: Because refrigeration systems in all aspects of production and manufacturing, there are strict requirements, the need to ensure that every link to do cleaning treatment.
But at present, the vast majority of cold water (frozen) machine manufacturers are purchasing parts and then assembling, so it is inevitable that some system imperfest phenomenon, serious will cause system blockage (generally blockage occurs at the entrance to the filter or expansion valve) so cold water (frozen) machine manufacturers have installed "filters" in refrigeration systems to filter out impurities in the system.
when impurities in the pipeline of the refrigeration system accumulate to a certain extent, it will cause the filter to clog, affect the amount of refrigerant passing through the system, and in severe cases, a low pressure failure occurs.
