Design and Precision Control of Plunger Metering Pumps: Experimental Analysis and Optimization

Abstract

A metering pump is a specialized device designed for the precise measurement of fluids. It is capable of handling a wide range of substances, including flammable, explosive, highly toxic, high viscosity, and low viscosity fluids, as well as complex mixtures such as crude oil, brine, and other solid-liquid combinations. With the advancement of automatic control requirements in production processes, more stringent standards are imposed on metering pumps. This paper examines the mechanical structure of the plunger metering pump. To enhance metering accuracy through PLC (Programmable Logic Controller) control, an effective experimental setup was developed to evaluate the metering accuracy of the pump.
