INVESTIGATION OF MULTI-STAGE CENTRIFUGAL PUMP'S PERFORMANCE WHEN PUMPING WATER-GAS MIXTURES WITH salt WATER ON THE STAND-LAYOUT OF THE PUMP-EJECTOR SYSTEM
The paper investigates the effect of salinity in the pumped-out liquid on the characteristics of a multistage centrifugal pump with a pre-switched on water-jet gas pump. It found that with an increase the mineralization of the working fluid and when gas is supplies at excessive pressures to the intake of water-jet gas pump, it enhances the stability of the finely dispersed water-gas mixture, which leads to a significant decrease in the harmful effect of free gas on the pump characteristics.
