How to test the comprehensive performance test bench of condenser electronic expansion valve

　　


The test bench simulates different working conditions to test the response speed, opening and closing degree, accuracy and other indicators of the electronic expansion valve to evaluate its performance in actual applications. How should the condenser electronic expansion valve comprehensive performance test bench be tested? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

　　It is suitable for testing the flow characteristics, valve opening pulse, valve leakage, maximum action differential pressure test, reverse valve opening differential pressure, fatigue resistance test, etc. of electronic expansion valves. It uses imported electronic digital flowmeters, with a flow test error of ±1.5%. The number of pulses can be set arbitrarily according to the valve opening requirements, and the flow change value of each pulse number can be displayed. The system is automatically controlled, the output test pressure ratio is adjustable, the valve input pulse number can be set, the system pressure, flow parameters and pulse number can be detected in real time, and the flow and pressure mutation points can be identified. After setting the parameters through the computer, the test can be started with one click, and the flow characteristics and valve leakage parameter curves can be generated and the test results can be recorded;
