Abstract

Die Erfindung betrifft eine helico-axiale Pumpe (1) zur Förderung eines Mehrphasengemischs (M), welche helico-axiale Pumpe (1) einen in einem Pumpengehäuse (6) um eine Längsachse (A) drehbar gelagerten Rotor (2) mit einem ersten Teilrotor (21) und einen zweiten Teilrotor (22) umfasst, wobei der erste Teilrotor (21) und der zweite Teilrotor (22) zur Kompression des Mehrphasengemischs (M) eine Kompressionsstufe (K, K1 E, K1 A, K2E, K2A) mit einem helico-axialen Laufrad (3) und einem Stator (4) umfasst. Erfindungsgemäss ist eine hydrodynamische Stabilisierungsbuchse (70) mit einer Stabilisierungsfläche (700) derart zwischen dem ersten Teilrotor (21) und dem zweiten Teilrotor (22) vorgesehen und ausgestaltet, dass vor der Stabilisierungsfläche (700) ein Stabilisierungsspalt (8) ausgebildet ist, so dass im Betriebszustand eine hydrodynamische Stabilisierungsschicht (S) aus einem Stabilisierungsmedium im Stabilisierungsspalt (8) bildbar ist. Die Erfindung betrifft weiterhin einen Rotor (2) für eine helico-axiale Pumpe (1), eine Hybridpumpe mit einem Rotor (2) für eine helico-axiale Pumpe 1, sowie ein Verfahren zur hydrodynamischen Lagerung eines Rotors (2) einer helico-axialen Pumpe (1).

The invention relates to a helico-axial pump (1) for conveying a multiphase mixture (M), which helico-axial pump (1) in a pump housing (6) about a longitudinal axis (A) rotatably mounted rotor (2) with a first part rotor (21) and a second sub-rotor (22), wherein the first sub-rotor (21) and the second sub-rotor (22) for compression of the multiphase mixture (M) a compression stage (K, K1 E, K1 A, K2E, K2A) with a helico-axial impeller (3) and a stator (4). According to the invention, a hydrodynamic stabilizing bush (70) with a stabilizing surface (700) is provided between the first part rotor (21) and the second part rotor (22) and configured so that a stabilizing gap (8) is formed in front of the stabilizing surface (700) in the operating state, a hydrodynamic stabilizing layer (S) can be formed from a stabilizing medium in the stabilizing gap (8). The invention further relates to a rotor (2) for a helico-axial pump (1), a hybrid pump with a rotor (2) for a helico-axial pump 1, and a method for hydrodynamic mounting of a rotor (2) of a helico-axial Pump (1).
