TECHNOLOGY OF JET PUMP APPLICATION TO IMPROVE EFFICIENCY OF VERTICAL DRAINAGE

Abstract

Vertical drainage systems are systems that use pumps and tube wells. The article proposes the use of a jet pump to boost the efficiency of vertical drainage. A laboratory equipment was used study the process of using a jet pump. The research examined the impact of the pressure pipe’ diameter on the suction process in a jet pump. The injection coefficient reached a maximum value of 50% at the efficiency of the flow meter d = 40 mm in pressure pipe. Based on statistical analysis of laboratory research findings, a relationship was retrieved to determine the suction capacity and suction height of the jet pump used in the proposed vertical drainage system
