摘要： Provided is a uniaxial eccentric screw pump enabling a stator to be easily separated into an outer cylinder and a lining member, and being capable of solving problems such as a positional shift and deformation of the lining member, and an occurrence of uneven wear and an unstable discharge amount associated with the positional shift and deformation. A stator (20) includes: a liner portion (22) having a cylindrical shape and being integrally formed so as to have an inner peripheral surface of an internal thread type; and an outer cylinder portion (24). The liner portion (22) includes, at both end portions thereof, flange portions (26, 26) protruding radially outward, and an outer cylinder mounting portion (28) is provided between the flange portions (26, 26). The outer cylinder portion (24) is mounted in a non-bonded state on the outer cylinder mounting portion (28), and both end portions of the outer cylinder portion (24) abut on the flange portions (26, 26), respectively.

摘要： The purpose of the invention is to provide a uniaxial eccentric screw pump in which a stator is easily separatable to an outer cylinder and a lining member, and a tightening margin is easily adjustable. The stator 20 has a cylindrical liner part 22 of which an inner circumferential face is integrally formed to be a female thread, and a cylindrical outer cylinder part 24. Flange parts 26 and 26 projecting outwardly in the radial direction are formed in both ends of the liner part 22, and an outer cylinder mounting part 28 is provided therebetween. The outer cylinder mounting part 28 is mounted to the outer cylinder part 24 in a non-adhesion manner, and both ends thereof contact the flange parts 26 and 26. The tightning margin can be adjusted by inserting or removing a shim 25 between the liner part 22 and the outer cylinder part 24.
