MODELING OF THE WORKING CYCLE OF THE PRESSURE-POWERED PUMP
Abstract
This paper presents an analysis of working parameters of the pressure-powered pump. Mathematical models for determining the pump filling and discharge periods were developed and statistically compared to experimental results. The statistical parameters of the final correlation between here presented mathematical model and experimental results are in the acceptable range. Pump characteristics are presented in the common manner: in the form of the pump head vs. capacity diagram.
