Abstract

Abstract: A multi-bar mechanism with an adjustable stroke applied to metering pumps is presentedd. The analytical kinematic model is established. The output capability of metering pumps is studied with different stuctural parameters. The relationship between performance and different choices of structural parameters is revealed, thus providing the theoretical basis for the design and control of metering pumps. The research results indicate that the stroke length of a piston is varied by adjusting the length of the control links, and the requirement i satisfied that it allows the piston stroke to be adjusted in length and permits the pump flow to be changed during the pump functioning.

Key words: adjustable mechanism, analytical kinematic model, metering pump, performance, structural parameters
