Design and application of an automatic testing system for servo-valve

Servo-valve plays very important role in the hydraulic system. Hence, it is very important to have accurate tests for servo- valve to ensure its high reliability and safety. In order to solve the problem of lower efficiency and high error rate of the manual testing, an automatic testing system was designed and developed in this paper, testing principles and measures were proposed. Static and dynamic characteristics testing experiments have been done in some kinds of standard servo-valve, all testing indexes in accord with the tested servo-valves. The experiments results indicate that the automatic testing system designed in this paper is a rapid, reliable, stable and well-functioned measurement system.
