Abstract (en)
[origin: WO2016119774A1] 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.
