How to use the electronic expansion valve flow test station for industrial refrigeration equipment

　　In industrial refrigeration technology, the electronic expansion valve is a key part, and the stability and accuracy of its flow characteristics are crucial to the operating efficiency of the refrigeration system. How to use the electronic expansion valve flow detection station for industrial refrigeration equipment? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

　　The equipment is suitable for the action test, flow test, and comprehensive oil pressure test of the electronic expansion valve flow. The whole process is monitored by PLC, and a special pulse drive board is customized for valve opening test. The number of pulses and frequency can be set according to demand, and the response is sensitive. A gas flow meter is used to detect the air flow at various openings of the electronic expansion valve. The corresponding flow conditions of the electronic expansion valve under various pulse opening values can be effectively detected. The air pressure, pulse parameters, detection time, and upper and lower limit alarms of the flow value can all be adjusted. The detection principle of the whole machine is scientific and reliable, and the operation is simple.
