Optimization Design of Suction Valve for Valve Controlled Pump

This paper presents an optimization design method, in which a mathematic model of dynamic characteristics or suction valve is established and an expression of the suction valve is employed as its object function. Several restrain conditions are determined rationally. Optimization design is carried on by means of "punishing function method" and BA8IC language. A suction valve or valve controlled pump of certain press is designed by means or optimization design method. Calculation shows that quantity of drainage or fluid pump increases by a percentage of above 6%. Stability analysis shows that the surction valve works stably.
