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

　　This equipment is suitable for flow testing of electronic expansion valves, four-way valves, and other pipe fittings. It is fully monitored by PLC+software and uses a gas flow meter to detect the corresponding flow of the test product. How to test the flow test bench of electronic expansion valves of industrial refrigeration equipment? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

　　Flow test: test pressure is 0.1MPa or 0.5MPa, valve opening pulse number is adjustable, valve opening frequency is adjustable (settable), flow rate is 0~1000L/min; multiple test points can be set (every 100 steps), each point is set with different pulse numbers, flow rates under different openings are tested in sequence, and whether the flow rate is qualified is automatically determined based on the upper and lower deviations of the flow rate. Flow curve can be drawn.
