Research Regarding Adaptive Design of Gear Pumps Used for Polymeric Products Engineering

Abstract

This paper present the results of the researches regarding innovative and adaptive design of gear pumps for engineering of polymeric products with application in production of injection molding machine. It shows the description of gear pump with innovative design and double gear pump – innovative design, highlighting innovative design feature through constructive adaptation depending on requirements, having (30 – 40) % smaller at the axial size, compared to the classic pumps. They highlight the competitive advantages of innovative pumps with superior technological parameters. The paper also shows numerical simulation of technological parameters for pumps in innovative and adaptive variant proving the correctness and the advantages of new variants. Using the innovative variant allows the development a family of gear pumps, single and double, extremely compact, robust, reliable and with low manufacturing costs.
