What are the technical requirements for the electronic expansion valve flow test station for industrial refrigeration equipment?

　　The test bench mainly tests the flow performance of the electronic expansion valve under different working conditions to reduce the error caused by human operation and improve work efficiency. What are the technical requirements for the flow test bench of the electronic expansion valve of industrial refrigeration equipment? Let's see how Guangzhou Zhipinhui Electronic Technology explains it.
