Contaminant Lock Life Prediction of Double Flapper-Nozzle Servo Valve

Abstract:

The thesis first analyzes the failure mechanism of contaminant lock, then the contaminant sensitivity theory or the Omega theory, which is first put forward by the Oklahoma state university hydrodynamic research center, is introduced and being applied to the servo valve contaminant lock life analysis and the contaminant sensitivity test method of servo valve is presented. After that, the value of servo valve contaminant lock sensitivity as well as the contaminant lock life can be calculated. It turned out that this method can accurately evaluate servo valves resistance on pollution lock and contaminant lock life, which can offer guidance on servo valve selecting and reliability analysis.
