A set of electronic expansion valve flow test equipment is designed to test flow of different types of electronic expansion valve.The design idea

hardware architecture and software design method are described.The equipment completes flow test by driving and controlling EXV.Software development is achieved in VB 6.0 environment.The experimental results show that the system successfully accomplishes flow characteristic test on EXV and the initial judgment of fault

with the advantage of advanced technology

accurate test

stable effect

and efficiency

and so on.
