Research on Axial Grinding and Zero Position Characteristic Test System of Jet Pipe Servo Valve Slide Valve

The jet pipe servo valve is widely used in aviation, aerospace, marine and civil fields due to its strong anti pollution capability, high sensitivity and low failure,etc. The principle of the slide valve axial grinding test bench was introduced. The simulation model of the spool axis matching grinding was established by modeling and simulation software AMESIM. The matching curves of the four sides of the spool valve assembly under different overlap were analyzed. The slide valve axial grinding and zero position test bench was built. The test verify the feasibility and functionality of the slide valve axial grinding test bench.The research has important significance to improve the servo valve manufacturing process level and production efficiency.
