用于从钻孔中输送黏性的或半黏性的介质的泵系统
摘要：
公开了用于从钻孔中输送黏性的或半黏性的介质的泵系统和方法。泵系统包括安装在钻孔中的井式管道(3)、马达(5)，该马达联接到偏心螺杆泵(7)上，其中，偏心螺杆泵(7)包括一个或多个定子(13)以及可偏心转动地容纳在该定子(13)中的一个或多个转子(15、15’)。还设有一个或多个连接器件(20、25)，偏心螺杆泵(7)通过连接器件以传力连接和/或形状配合连接的方式固定在井式管道(3)中。为了将偏心螺杆泵从钻孔中取出，偏心螺杆泵(7)通过一个或多个连接器件(20、25)具有轴向运动自由度地被保持。
摘要（英）：

The invention relates to a pump system and a method for pumping viscous or partially viscous media out of a borehole. The pump system comprises a well pipe (3) which is installed in the borehole and a motor (5) which is coupled to an eccentric screw pump (7), said eccentric screw pump (7) comprising one or more stators (13) and one or more rotors (15, 15') which are received in the stator(s) (13) so as to rotate eccentrically. One or more connection means (20, 25) are also provided, by means of which the eccentric screw pump (7) is fixed in the well pipe (3) in a force-fitting and/or formfitting manner. For the purpose of removing the eccentric screw pump from the borehole, the eccentric screw pump (7) is held by means of the one or more connection means (20, 25) with an axial freedom of movement.
