What are the uses of the electronic expansion valve flow test bench?

　　
This flow test bench automatically plots the corresponding pulse-flow curve for electronic expansion valves, while four-way valves and pipe fittings display the current flow rate under test. What are the uses of the electronic expansion valve flow test bench? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

1. Power Supply: AC 220V 50Hz

2. Test Medium: Air

3. Air Source Pressure: 0.8MPa clean compressed air

4. Flow Meter Performance: Three flow meters are provided, with ranges of 0-50L/min, 0-250L/min, and 0-1000L/min.

5. Pressure Reducing Valve Performance: Imported high-precision electrical proportional pressure regulating valve with a sensitivity of 0.2%F.S. and repeatability within ±0.5%F.S.

6. Test Air Pressure: 0.1-0.5 MPa compressed air (adjustable)

7. Flow Test: Test pressure is 0.1 MPa or 0.5 MPa, valve opening pulse count and frequency are adjustable (configurable), and flow rate range is 0-1000 L/min. Multiple test points can be set (every 100 steps), with a different pulse count set for each point. Flow rates at different openings are sequentially tested, and acceptance is automatically determined based on the upper and lower flow deviations. A flow curve can be plotted.
