摘要： A multistage centrifugal pump in which each stage includes a one-piece or multi-piece housing and an impeller disposed therein. The pump stages are arranged between an inlet end member and an outlet end member and retained therebetween by connectors so as to be connected to a flow-guiding system. All impellers are positioned on a single pump shaft that is supported by at least two pump bearings. One end of the pump shaft is provided with a device for receiving a connector of a drive unit, and outer support members are disposed at mounting points adjacent the end members in order to mount the centrifugal pump in its installation location. The pump shaft (3) is supported by two two pump bearings (11, 12), with the maximum distance (LL) between confronting sides of the two pump bearings (11, 12) being less than or equal to a minimum structural stage height (LM) multiplied by the number of pump stages (2.1-2.5) minus 1.

摘要： A pressure exchanger for transferring pressure from a higher pressure liquid in a first liquid system to a lower pressure liquid in a second liquid system having a housing (8) with inlet and outlet connection openings (10-10.3) for each liquid and a rotor (1) arranged in the housing for rotation about a longitudinal axis. The rotor has a plurality of through channels (13) arranged around the longitudinal axis with openings (12) on axial end faces (2, 3) of the rotor. The rotor channels (13) are connected to the connection openings (10-10.3) through flow openings (11-11.3) in the housing such that during rotation of the rotor high pressure liquid and low pressure liquid are alternately supplied to the respective systems. A predominantly axially extending flow transition is formed between the flow openings (11-11.3) in the housing and the openings (12) of the rotor channels (13), and the flow openings in the housing form part of curved cavities (19) with each cavity (19) simultaneously covering several rotor channel openings (12) and having a shape which equilibrates the liquid flow speed in the vicinity of the housing flow openings (11-11.3). External surfaces (5-5.3) of the rotor (1) have an energy converting or energy transmitting configuration (6), and a partial flow (TS) of high pressure and/or flow energy impinging on the configuration (6) produces rotation of the rotor (1). A regulator (7) the varies the amount of the partial flow (TS) and the rotational speed of the rotor (1) and controls the rotational speed of the rotor for substantially shock-free admission of the mass flow into the rotor channels (13).

摘要： A pressure exchanger for transferring pressure energy from a first liquid in a first liquid system to a second liquid in a second liquid system, having a housing with inlet and outlet connection openings for each liquid and a rotor (1) arranged in the housing for rotation about a longitudinal axis. A number of through rotor channels (2) are arranged around the rotor longitudinal axis with openings (4) on each axial end face of the rotor. The rotor channels (2) are arranged for connection through opposing flow openings formed in the housing to the connection openings of the housing such that during rotation of the rotor, high pressure liquid and low pressure liquid are alternately introduced into the respective systems. Liquid flowing to the rotor through the flow openings formed in the housing generates a circumferential force component (cu) in the relative rotating system of the rotor for driving the rotor, and starting at or following the openings (5) a flow guiding configuration (8) formed as a rotor channel flow diverting contour is arranged in the rotor channels (2).

摘要： A pressure exchanger system having at least two tubular chambers, in which a plurality of reversing valves reverse the flow paths of fluid flows through the at least two tubular chambers. At least one driven reversing valve alternately reverses the flow paths between a supply source, which supplies a high-energy high-pressure fluid, and the tubular chambers. In reversing the liquid flows and shutting off previously open flow paths, the driven reversing element in the reversing valve executes a discontinuous or variable movement sequence.
