CONTROLLING THE GAP GEOMETRY IN AN ECCENTRIC SCREW PUMP
The invention relates to an eccentric screw pump (1) for delivering liquids loaded with solids, having a rotor (4) wound helically, a stator (2), having an inlet (10) and an outlet (12), in which the rotor (4) is rotatably arranged about a longitudinal axis (L1) of the stator, and which has a screw-like inner wall (8) corresponding to the rotor (4), wherein the rotor has a form tapering toward the outlet (12) or the inlet (10), preferably a conical form and/or a varying eccentricity (e1, e2), and wherein rotor (4) and stator (2) are arranged relative to each other and formed such that at least one chamber (5) is formed, which is used for conveying the liquid, and the chamber is separated off by a narrowing (7) in particular a sealing line (D). The invention is characterized by an adjusting device for adjusting an axial relative position of rotor (4) and stator (2), wherein the adjusting device (39) is designed to widen the narrowing (7) between rotor (4) and stator (2).

The invention relates to a seal arrangement for saving a pump shaft in a rotary piston pump (10) designed for delivering pumped delivery fluid, comprising a sealing fluid pumping device (20) having a pump inlet (21) and a pump outlet (22), a sealing chamber (40), which is connected to the pump outlet (22) and is arranged adjacent to the pumping chamber of the rotary piston pump (10) and is sealed off with respect to the pumping chamber by means of a first shaft seal enclosing the pump shaft, wherein the sealing chamber (40) is loaded via the pump outlet (22) with a fluid pressure resulting from the fluid pressure difference generated by the sealing fluid pumping device (20), and, by means of interaction of this fluid pressure with the first shaft seal, seals off the pumping chamber against the escape of pumped delivery fluid from the pumping chamber along the pump shaft.
