The compressor needs to be filled with refrigerant while the system is running. This type of compressor is filled with refrigerant. To this end, the insulation resistance of the refrigerant was tested. The voltage was applied between the two electrodes at intervals to test that the insulation resistance was 23, which did not meet the requirements of the refrigerator factory. In the assembly process of the refrigerator factory, 10 compressors were added and the gas was added. After standing 10 to fully dissolve, the insulation resistance was measured. As a result of the measurement, it can be seen that after the compressor is assembled to the refrigerator and charged with the refrigerant, if a large amount remains on the film and the glass body, the insulation resistance of the compressor is low, which does not meet the requirements of the refrigerator factory. It is dangerous if the compressor is operated in the system for a long period of time with poor insulation, and according to experience, there are few cases where the compressor is subjected to electrical breakdown during use. The reason is that after the gas is added to the compressor, it is dissolved with the refrigerating machine oil adhering to the surface of the insulating film and the glass body of the sealing post, resulting in a decrease in the overall insulation resistance of the compressor. Then shake the compressor to make the refrigerating machine oil fully adhere to the insulating film and the glass body of the terminal, and immediately detect the insulation resistance. As shown in the meter, the compressor can be seen in the system after a period of operation, the refrigerant is in the whole system. The dissolution tends to balance. The insulation performance of the compressor is restored to a safe level. Based on the above test results, it is recommended that the refrigerator factory revise the insulation performance test specification, that is, after the compressor is injected into the refrigerator and the hl is operated, the insulation test is performed. At this point, the problem has been better resolved. In summary, there are many factors that affect the insulation performance of the compressor. Some factors are constant, and some factors change with time and environment. Only through objective and comprehensive analysis and argumentation can the conclusion be accurately drawn. From another perspective, compressors, like all other household appliances, are always the number one priority, and both designers and manufacturers must seriously consider this issue.
Air dryer is the ideal equipment for drying the end products like
starch, modified starch and wheat gluten in starch industry. Starch dried by
this equipment features in clean appearance, glossy luster, smooth powder, and
stable moisture while wheat gluten features in high water absoption, excellent
activity and original flavor. this equipment can be designered and procuced
based on customers' requests on space and warehouse, which is convenient for
installation, operation and maintenance .The
air dryer is alsosuitable for raw materials that are hydrophobic behavior
,small granule,thermal sensitivity and
not afraid of broken. Good state of distribution between air and solid phase
carries out convective dry in order to
remove moisture.
