Abstract:
Static models of meter-in and meter-out fluid power system are built
through resistance characteristics of control valve orifices to find the
optimum static operation points. It is concluded that flow conductance
reversing criterion and energy loss conservation criterion of meter-in
and meter-out fluid power system, and is presented that the choosing
principles of static operation points respectively from three aspects of
energy loss, velocity sensitivity, pressure range limitation.
Consequently the theory foundation is provided for designing of valve or
system and field debugging of meter-in and meter-out fluid power
systems.
