摘要： A screw displacement pump is provided. The screw displacement pump is of single-entry, double-shaft construction with an external bearing of the two screw shafts. A pump housing encloses the screw shafts by forming feed chambers and externally delimiting the feed chambers with its internal shell surface, as well as a suction chamber for the medium to be induced and a pressure chamber to accommodate the medium pumped by the screw shafts. The pump housing is inserted into a pressure housing and attached to the pressure housing, so that the pressure chamber encloses the pump, at least in part.

摘要： The invention relates to a fluid-conveying machine, in particular, a pump having a component rotating in a stationary housing part inside an annular gap. The stationary housing part separates an interior having a higher product pressure from an exterior having a lower pressure. A rotating component is mounted in an external bearing which is sealed with respect to the interior via a sealing system. In order to improve the sealing, the invention provides that the annular gap is formed between two sliding bearing shells which comprise extremely hard, wear-resistant materials and, in accordance with the operating principle of a radial sliding bearing, form a first pressure-reducing stage. A feedback device, which feeds back the leakage from this first sealing stage into the conveying process of the machine, is connected downstream of the first pressure-reducing stage. A second sealing stage is arranged axially downstream of the feedback device. The second sealing stage may be constructed as a simple seal, such as a lip seal and/or a simple end face seal.
摘要翻译：本发明涉及一种流体输送机，特别是具有在环形间隙内的固定壳体部分中旋转的部件的泵。固定壳体部分将具有较高产品压力的内部与具有较低压力的外部分离。旋转部件安装在通过密封系统相对于内部密封的外部轴承中。为了改善密封性，本发明提供了环形间隙形成在包括极硬耐磨材料的两个滑动轴承壳之间，并且根据径向滑动轴承的工作原理形成第一减压阶段。反馈装置将从第一密封阶段的泄漏反馈到机器的输送过程中，连接在第一减压级的下游。第二密封台被布置在反馈装置的轴向下游。第二密封阶段可以构造成简单的密封，例如唇形密封和/或简单的端面密封。

摘要： An eccentric screw pump with a pump casing (1) having an intake stub (6) and a delivery stub (7) and enclosing a suction chamber (8) and a delivery chamber (9). A stator (2) arranged in the said casing surrounds a rotor (3) that can be driven by a motor. In order to permit multi-phase delivery, a lower portion (9a) of the delivery chamber (9) is connected to the suction chamber (8) via a liquid bypass line having a valve opening (13) that can be actuated by a control element on the basis of the differential pressure between the delivery and the suction chambers (9, 8) in such a way that the valve (13, 14) is open in the case of the differential pressure which arises in the delivery of dry-running gas but is closed in the case of the differential pressure which arises during the delivery of liquid.
