偏心螺杆泵
摘要：
本发明涉及一种偏心螺杆泵，所述偏心螺杆泵具有至少一个由弹性材料构成的定子(1)和在所述定子(1)中可转动的转子(2)，其中，所述定子(1)至少局部地被定子套(3)包围。所述定子套(3)构成为包括至少两个套区段(19)的纵向分开的套并且形成定子夹紧设备，所述定子(2)能够借助所述定子夹紧设备沿径向方向相对于所述转子(1)夹紧。所述泵的特征在于，所述套区段(19)在端部侧至少分别具有一个带有第一夹紧面(21)的夹紧法兰(20)，并且在所述夹紧法兰(20)上套装有带有第二夹紧面(24)的一个或多个可沿轴向方向移动的夹紧元件(22、23)，其中，所述第一夹紧面(21)和所述第二夹紧面(24)构成为并且配合作用为，使得所述定子套(3)在所述夹紧元件(22、23)轴向移动期间能够沿径向方向相对于所述定子(1)夹紧。
摘要（英）：

The invention relates to an eccentric screw pump, comprising at least one stator (1) composed of an elastic material and a rotor (2) that can be rotated in the stator (1), the stator (1) being surrounded by a stator casing (3) at least in some regions. The stator casing (3) consists of at least two casing segments (19) as a longitudinally divided casing and forms a stator clamping device, by means of which the stator (2) can be clamped against the rotor (1) in the radial direction. The pump is characterized in that the casing segments (19) have at least one clamping flange (20) having first clamping surfaces (21) at each end of the casing segments and that one or more clamping elements (22, 23), which can be displaced in the axial direction and have second clamping surfaces (24), are placed onto the clamping flange (20), the first clamping surfaces (21) and the second clamping surfaces (24) being designed in such a way and interacting in such a way that the stator casing (3) can be clamped against the stator in the radial direction in the course of an axial displacement of the clamping elements (22, 23).
