How to perform life test on refrigerator four-way valve test bench

　　

This test bench is mostly used in the production and testing of refrigeration systems such as air conditioning, refrigeration, and freezing. By testing and evaluating the four-way valve, the performance and reliability of the refrigeration system can be improved and the failure rate can be reduced. How does the refrigerator four-way valve test bench perform life testing? Let's see what Guangzhou Zhipinhui Electronic Technology has to say.

　Conventional four-way valve life test:

① Set the number of test actions on the software, 0~999999 times can be set, the coil power supply is output through the variable frequency power supply program control, the number of coil power on and off can be freely set, 0~999999, used to assess the switching life of the four-way valve.

② The test pressure is 0~2.4Mpa and can be adjusted manually.

③ The total number of tests, the actual number of tests, and the test voltage can be displayed, and the number of switching failures and the time of occurrence can be recorded.

④ Action frequency: 12 times/min (adjustable)

⑤ Refueling function during the test: There is a refueling function during the life test, and the refueling volume is 30 ml/hour, which can be manually controlled
