How to test the flow test bench of electronic expansion valve of industrial refrigeration equipment

　　

The test bench can provide a variety of test scenarios by simulating the working conditions in various actual working environments. How to test the flow test bench of the electronic expansion valve of industrial refrigeration equipment? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

　　The whole process is monitored by PLC, and a special pulse drive board is customized for valve opening test. The number of pulses and the frequency can be set according to the needs, and the response is sensitive. A gas flow meter is used to detect the air flow at various openings of the electronic expansion valve. It can effectively detect the corresponding flow conditions of the electronic expansion valve under various pulse opening values. The air pressure, pulse parameters, detection time, and upper and lower limit alarms of the flow value can all be adjusted. The detection principle of the whole machine is scientific and reliable, and the operation is simple. It is an ideal auxiliary detection equipment for manufacturers.
