Research on performance of slide-valve in water hydraulic servo-valve with hydrostatic bearing
In order to optimize the motion characteristics of slide-valve in water hydraulic servo-valve. Hydrostatic bearing technology has been used between valve core and sleeve. The research on performance about the static characteristics of slide-valve in water hydraulic servo-valve with hydrostatic bearing structure and traditional throttle with fixed orifice has been carried. The mathematical model of the pressure-flow characteristics, the pressure sensitivity characteristics and pressure characteristics of servo-valve has been established. Research shows, the application of hydrostatic bearing technology can make the linear relationship of the pressure - flow characteristics of the nozzle-flapper valve maintained, the pressure sensitivity can be maintained constant, but pressure characteristics of servo-valve become worse.
