Abstract

Abstract A liquid with entrained gas is fed through a supply pipeline connected coaxially to the suction side of a centrifugal pump, and a gas-discharge pipe has one end portion extending coaxially into the supply pipeline, there being wings arranged to be driven so as to rotate in a path extending around the axis of the gasdischarge pipe and concentric to the pump shaft. The other end portion of the gas-discharge pipe is connected to a vacuum source, and the wings have portions extending axially along this discharge pipe in the vicinity of its opening which receives the gas to be discharged.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 138 words
Apparatus for separating a gas from a liquid, which comprises a centrifugal pump having a housing provided with an inlet and an outlet, the pump also having a rotor mounted in the housing, a pipeline connected to the pump-housing inlet coaxially of the rotor and through which the liquid is fed to said inlet, a gasdischarge pipe extending into said pipeline and having an inner end portion disposed coaxially of the rotor within the pump housing, a vacuum source connected to the other end portion of the gas discharge pipe, and wings arranged to be driven by means so as to rotate in a path extending around the gas-discharge pipe and concentric to the rotor axis, said wings having portions extending a distance axially along said discharge pipe in the vicinity of its opening at its inner end.
Claim 2
Dependent Claim 138 words
Apparatus for separating a gas from a liquid, which comprises a centrifugal pump having a housing provided with an inlet and an outlet, the pump also having a rotor mounted in the housing, a pipeline connected to the pump-housing inlet coaxially of the rotor and through which the liquid is fed to said inlet, a gasdischarge pipe extending into said pipeline and having an inner end portion disposed coaxially of the rotor within the pump housing, a vacuum source connected to the other end portion of the gas discharge pipe, and wings arranged to be driven by means so as to rotate in a path extending around the gas-discharge pipe and concentric to the rotor axis, said wings having portions extending a distance axially along said discharge pipe in the vicinity of its opening at its inner end.
Claim 3
Dependent Claim 17 words
Apparatus according to claim 1, in which said wings are carried and driven by the pump rotor.
