Study of the Squeeze Film Damper of Larger Flow Rate High-speed on/off Valve
A new type of squeeze film damper(SFD) is designed to reduce spools impact and vibration which happen in the two-stage larger flow rate high-speed on/off valve with the 450 L/min flow rate and 8ms turn-off time, the valves sealing performance、 reliability and service life improve largely, and the valves response speed doesnt drop. The simulated and experimental results show: The damper has optimum buffering performance when oil film thickness is 0.1mm, and the spool closing process approach ideal state. The valve will has a great potential application in the powerful occasions because of its perfect performance: larger flow rate、 fast response and novel damper.
