Abstract
A hydraulic arrangement (1) is provided comprising a pressure exchanger (2) having an axis (3) of rotation, and a booster pump (4), said pressure exchanger (2) and said booster pump (4) being connected to each other. Such a hydraulic arrangement should have a good efficiency. To this end a single connection flange (5) is provided between said pressure exchanger (2) and the booster pump (4).
Claims18
A hydraulic arrangement comprising a pressure exchanger having an axis of rotation, and a booster pump, said pressure exchanger and said booster pump being connected to each other, wherein a single connection flange is provided between said pressure exchanger and said booster pump, wherein said flange comprises a low pressure input of said pressure exchanger and a high pressure channel connecting a high pressure output of said pressure exchanger and a low pressure inlet of said booster pump, wherein said high pressure output of said pressure exchanger and said low pressure inlet of said booster pump are offset relative to each other in a direction of rotation of said pressure exchanger, the direction of rotation being in a circumferential direction of said pressure exchanger, and wherein said booster pump has at its low pressure inlet an inlet area having a width in a radial direction, said width increasing in the direction of rotation.
A hydraulic arrangement comprising a pressure exchanger having an axis of rotation, and a booster pump, said pressure exchanger and said booster pump being connected to each other, wherein a single connection flange is provided between said pressure exchanger and said booster pump, wherein said flange comprises a low pressure input of said pressure exchanger and a high pressure channel connecting a high pressure output of said pressure exchanger and a low pressure inlet of said booster pump, wherein said low pressure input of said pressure exchanger has a directional component which is arranged tangentially with respect to a circle line around said axis of rotation, and wherein said low pressure input has a cross section in a plane perpendicular to said axis of rotation, said cross section increasing in direction of flow.
