摘要:
Disclosed is a pump (10) comprising a rotor (70) whose vane (120) laterally delimits a pumping duct (124) that is provided with an inlet (152) and an outlet. A seal slider (182) that can be displaced in an axial direction sealingly rests against the rotor vane in an axial direction on both sides and subdivides the pumping duct (124) between the inlet (152) and the outlet. A stator (130) is removably disposed in the zone of the annular space that is located between the rotor hub and the outer wall of the housing at a distance from the inlet and the outlet. An annular groove which forms the two axial lateral faces and the outer radial boundary of the pumping duct (124) is provided in the stator. Sealing means (410) are placed between the stator (130) and the housing (12).

The sealing surfaces, which are provided between a somewhat wavy, surrounding rotor collar (120) of a rotor rotating inside a pump, and the inner walls of a slot-like opening, which is provided in a slide (182) that can be displaced inside the pump in an axial direction, are characterized in that the polygonal, in particular, rectangular cross-section of the rotor collar (120) comprises rounded corner areas (610, 612, 614, 616) and that the lateral walls (620) of the opening (184) provided in the slide (182) have curvatures (634, 636, 646, 642) such that the rotor collar (120), when rotating, also rests in a sealing manner with its rounded corner areas (610, 612, 614, 616) against the lateral walls (620) of the opening (184).
摘要:
Die Pumpe hat in einem Lager- und Dichtungsgehäuse (21) einen Eintrittsraum (28) und eine Antriebswelle (23), die den Rotor (55) und die beiden mit ihm verbundenen Exzenterführungsscheiben (40.2) antreibt. In diesen sind in Ringnuten Schieberringe (45.1, 45.2) gelagert. Diese tragen die Sperrschieber (46.1, 46.2), welche über Anlagedichtflächen in Schieberaufnahmeräume eintauchen oder aus diesen herausgezogen werden. Die Pumpe ist für hohe hygienische Anforderungen, wie bei Nahrungsmitteln, Medikamenten und Kosmetika, geeignet und kann auch empfindliche Bestandteile, wie Früchte oder sonstige Nahrungsmittelbestandteile, schonend fördern.
摘要:
A pump (10) comprises a rotor (70) whose rotor collar (120) laterally delimits a pump channel (124) having an inlet (152) and an outlet. A sealing slide (182) that can be displaced in an axial direction rests, while sealing on both sides, against the rotor collar (120) in an axial direction and partitions the pump channel (124) between the inlet (152) and the outlet. An elastically deformable sealing body (510) is provided between the slide guide (162), against which the slide (182) rests in a sealing manner and can be displaced in an axial direction (31) by means of the rotation of the rotor collar (120), and at least one cover (28), the lateral wall (24) and the rear wall (14) of the pump case (12).
摘要:
The invention relates to a pump (10) comprising a rotor (70) whose collar (120) laterally describes a pump channel (124) provided with an input (152) and an output. An axially adjustable sealing disc (182) is tightly placed on two sides of the rotor collar (120) in an axial direction and divides the pump channel (124) into the input (152) and the output. A first bearing for a drive shaft (60) is axially arranged in the clear space occupied by the rotor (70) and makes it possible to axially support said drive shaft.

摘要:
The invention relates to a pump (10) which is provided with a pump housing (12) comprising a cover (28), a rear wall (14) and an envelope wall (24) disposed therebetween. The collar (120) laterally describes a pump channel (124) provided with an input (152) and an output. The internal surface of the rear wall (14) is provided with a thin plate (15, 15.2) or a coating in such a way that medium pumped by the pump housing (12) does not contact said rear wall (14). The thin plate (15, 15.2) or the coating is made of material taking medium properties into account. The rear wall (14) is made of a rough material such as a cast material.
