摘要： An acoustic damper includes an upstream wall with an inlet aperture and a downstream wall with an outlet aperture. The acoustic damper includes a first resonator that is supported by at least one of the upstream wall and the downstream wall. The acoustic damper also includes a second resonator that is supported by at least one of the upstream wall and the downstream wall. The first resonator and the second resonator are arranged in-parallel. Also, the first resonator and the second resonator are configured to cooperatively attenuate acoustic energy associated with a fluid flowing from the inlet aperture to the outlet aperture.

摘要： A low-cavitation impeller for a centrifugal pump is provided. The impeller provides a smooth flow path from the inducer section through to the outlet section. Continuous main blades run from a leading edge at the inlet eye to a trailing edge at the impeller outlet, and continuous secondary blades run from a leading edge in the transition region to a trailing edge at the impeller outlet.

摘要： A method of operating a compression system includes determining, by a controller, at least one of an operational point distance to surge and a surge margin based upon at least one of an electrical power consumed by a compressor and an electrical current consumed by the compressor, and at least one thermodynamic state measurement associated with the compressor.

摘要： A method for controlling an inlet-adjustment mechanism in an air inlet for a compressor so as to switch the mechanism in a binary fashion between two positions P1 and P2 for adjusting a flow area of the inlet. The method includes identifying a threshold line on a compressor map of pressure ratio versus corrected flow rate for the compressor. The threshold line is a line on which the pressure ratio and flow rate of the compressor are the same for the P1 and P2 positions of the inlet-adjustment mechanism at equal speeds. When the operating point of the compressor on the compressor map crosses the threshold line, the inlet-adjustment mechanism is switched from one of its binary positions to the other.

摘要： A scroll casing forms a scroll flow passage of a centrifugal compressor, and provided that, in a cross section of the scroll flow passage, pEi is an inner end of the scroll flow passage in a radial direction of the centrifugal compressor, and Mh is a middle point of a maximum flow-passage height Hmax of the scroll flow passage in the axial direction of the centrifugal compressor, the scroll flow passage has a separation suppressing cross section in which the inner end Ei is disposed on an inner side, in the radial direction, of a diffuser outlet, and the inner end Ei is disposed on a back side, in the axial direction, of the middle point Mh, in a section disposed at least partially in an upstream region of a connection position of a scroll start and a scroll end.
