Abstract

The invention provides a uniaxial eccentric screw pump, which comprises: a casing (6) having a first locking receiving portion, a stator (8) connected to the casing (6) and having an internal thread formed on the inner peripheral surface, which can The rotor (9) inserted through the stator (8) and composed of an externally threaded shaft has a second locking receiving portion and an end connected to the stator (8) on the side opposite to the housing (6) Bolts (10), brackets (23) holding the stator (8) between the housing (6) and the end bolts (10). The bracket (23) has a first locking part (38) locked to the first locking receiving part of the housing (6), and a second locking part (38) locked to the second locking receiving part of the end bolt (10). The stop part (39), the adjustment part (37) capable of adjusting the distance between the first stop part (38) and the second stop part (39).

Description

technical field [0001] The invention relates to a uniaxial eccentric screw pump. Background technique [0002] At present, as a uniaxial eccentric screw pump, there is known a uniaxial eccentric screw pump having a structure that includes an externally threaded rotor directly connected to an output shaft, rotatably supported in a casing via a bearing, and having a rotation axis A stator having a female-threaded inner surface arranged eccentrically with respect to the rotation axis of the rotor (for example, refer to Patent Document 1). [0003] However, in the above-mentioned conventional uniaxial eccentric screw pump, the housing has a structure in which the suction portion and the discharge portion are screwed to both end portions of the main body portion, respectively. The stator housed in the housing is a resin-made consumable and needs to be replaced periodically. It is cumbersome and cumbersome to loosen the screws to detach the suction part and the discharge part fro...
