摘要： Stator casing (8) of an eccentric screw pump (4) having an elastomeric stator inner part (9) containing a plurality of shell-like casing segments (6), and production method for a stator casing of this kind, with which the expenditure on servicing work can be reduced. To this end, according to the invention, casing segments (6) which are adjacent in the longitudinal direction of the stator casing (8) are arranged around the longitudinal axis of the stator casing (8) such that they are offset in relation to one another, wherein each casing segment (6) has connecting means (18) and at least four casing segments (6) are in engagement with one another and form a composite. In order to produce the stator casing (8), an axial force component is applied to the casing segments (6) by clamping, wherein the casing segments (6) engage with one another, as a result of which a radial force component is generated and the composite is formed.

摘要： The invention relates to an eccentric screw pump comprising a stator-rotor system having a rotor with a rotor screw and a stator with an inner thread. The stator comprises a support element and an elastomer part, wherein the support element completely surrounds some sections of the elastomer part. According to the invention, the stator-rotor system has an adjustment mechanism for adjusting the stator. The adjustment mechanism is coupled via a controller to at least one sensor for determining actual operating parameters of the stator-rotor system and/or of the eccentric screw pump, wherein an actuation of the adjustment mechanism can be carried out by the controller, taking into consideration the actual operating parameters determined by means of at least one sensor. The invention also relates to a method for adapting the operating state of an eccentric screw pump.

摘要： The invention relates to a method for adjusting a stator and to a stator-rotor system (10) of a progressive cavity pump, comprising a rotor having a rotor screw and a stator (3) having an internal thread. The stator comprises a supporting element (5) and an elastomer part (4). The supporting element (5) surrounds the elastomer part (4) fully in some regions. According to the invention, the stator-rotor system has an adjustment mechanism (12) for adjusting the stator (3), which adjustment mechanism comprises two adjustment elements (13, 14), which are arranged on the stator-rotor system and the distance between which can be varied. In a first working position, the two adjustment elements (13, 14) have a first distance from each other. In a second working position, the two adjustment elements have a second distance, which is not equal to the first distance. In the second working position, the cross-section and the length of the elastomer part (4) of the stator (3) is varied in relation to the cross-section and the length of the elastomer part in the first working position.
