Hydraulic calculation of power plant for mixture transport from the big depths

Abstract

In the pump plant application it is often necessary to transport fluid from the depths that are greater than pump suction height. For that purpose it is not always possible to use mamut pumps because of solid ingredients in the fluid or low efficiencies. In that case one can use plants that combine turbo pumps and ejectors. In principle, turbo pump is placed above liquid level, while ejector is sunk into the liquid. In this paper is presented the calculation method for mentioned plant. Different configuration of turbo pumps andlejectors are considered inlorder to define conditions for plant efficiency increase. 1
