What standards does the air conditioning electronic expansion valve performance test bench meet?

　　

This test bench is mainly used to conduct comprehensive testing of the various performances of electronic expansion valves. The design follows the principles of science, accuracy and efficiency to ensure the reliability and effectiveness of the test results. What standards does the air conditioning electronic expansion valve performance test bench meet? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

　　This machine is designed according to JBT-10212 and JBT-10386. It is suitable for testing the flow characteristics, valve opening pulse, valve port leakage, and maximum action differential pressure test of electronic expansion valves. It uses imported electronic digital flowmeters, and the flow test error is better than ±1%. The number of pulses can be set arbitrarily according to the valve opening, 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, and the pressure, flow parameters and pulse number of the system are detected in real time. 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 port leakage parameter curves are generated and the test results are recorded.
