LIQUID-GAS SEPARATOR

摘要

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 which connect each blade with an associated vane and which are shaped to provide a smooth transition for the fluid mixture flowing between the inducer and the centrifugal separator. The apparatus is capable of providing a high relatively constant flow rate, even for large volumetric ratios of gas to liquid.
