What are the test procedures for the electronic expansion valve flow test bench?

　　
This device is suitable for electronic expansion valve flow rate actuation testing, flow rate testing, and comprehensive oil pressure testing. Its testing principles are scientific and reliable, and its operation is simple. Let's take a look at the testing process for an electronic expansion valve flow rate test bench. Let's see how Guangzhou Zhipinhui Electronic Technology explains it.

　　Full PLC monitoring and a custom-designed pulse driver board are used for valve opening degree testing. The pulse quantity and frequency can be customized to meet specific requirements, ensuring a highly responsive response. A gas flow meter is used to detect air flow at various electronic expansion valve openings. This effectively measures the corresponding flow conditions for various pulse opening values. Air pressure, pulse parameters, test time, and upper and lower flow rate alarm limits are all adjustable. This makes it an ideal auxiliary testing device for manufacturers.
