UNSTEADY HYDROMECHANICAL SPECIFICATIONS OF VALVE FLOW OPERATOR

Abstract

The characteristics of the hydromechanical positioner of the hydrodrive are investigated. Its performance is defined under the flow unsteadiness through the identification of the real modes of the device in the special flow lab. The approximation of the obtained dependences refines the mathematical model of the valve flow operator, and totally — of the positioning hydrodrive dynamic system.
