The technology of using a jet pump to increase the efficiency of vertical drainage

Abstract

Vertical drainage systems, which rely on pumps and tube wells, are widely recognized for their effectiveness despite drawbacks such as high costs and significant energy consumption. In a recent study, the integration of a jet pump into vertical drainage systems was explored to enhance their efficiency. A specialized laboratory setup was developed to examine the use of a jet pump within these systems. The research focused on understanding how the diameter of the pressure pipe affects the jet pump’s suction capabilities. It was found that the jet pump operated at its highest efficiency, 50%, with a pressure pipe diameter of 40 mm. Statistical analysis of the laboratory data led to the formulation of a relationship for estimating both the suction capacity and suction height of the jet pump in the enhanced vertical drainage system.
