Self-Fixing Stator Housing

摘要

A stator casing of an eccentric screw pump with an elastomer stator inner part including a plurality of shell-like casing segments and a production method for such a stator casing, with which the outlay for maintenance work can be reduced. According to the invention, casing segments adjacent in the longitudinal direction of the stator casing are disposed offset with respect to one another around the longitudinal axis of the stator casing, wherein each casing segment includes connection means and at least four casing segments engage with one another and form a composite. For the production of the stator casing, the casing segments are acted upon by an axial force component as a result of clamping, wherein the casing segments engage with one another, as a result of which a radial force component is generated and the composite is formed.
