How to perform flow test on the refrigerator valve flow test bench

　　
The system automatically draws the corresponding pulse-flow curve for the electronic expansion valve, and the four-way valve and pipe fittings display the current flow of the test. The whole machine detection principle is scientific and reliable, the operation is simple, and the response is sensitive. How does the refrigeration machine valve flow test bench perform flow testing? 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.
