Abstract
A centrifugal liquid-gas separator apparatus which is particularly adapted for use downhole with a submergible pump comprises an elongated hub having disposed on its periphery helical blades defining a screw-type inducer for pressurizing a liquid-gas fluid mixture entering the apparatus, axially extending vanes defining a centrifugal separator for separating the liquid and gas components of the fluid mixture, and smoothly curved blade segments disposed intermediate the blades and the vanes for providing a smooth transition for the fluid mixture flowing from the inducer to the centrifugal separator. The apparatus is capable of maintaining a substantially constant flow rate over a large range of volumetric ratios of gas to liquid.
