Abstract: A stator jacket (12) and a stator lining (22) of elastomeric material together form a tubular pump stator (10) the ends (20) of which are connected to a connecting piece (36) of a casing portion (32, 34) each. The stator jacket (12) has at least one parting area (14) extending throughout its length. This and the region of the stator lining (22) located radially inside thereof as well as the junctions of the connecting pieces (36) with the stator jacket (12) are designed such that the pump stator (10) will burst in at least one parting area (14, 16) when a predetermined positive internal pressure is exceeded. This provides pressure relief before a risk of explosion can develop when explosives are being conveyed.

Abstract: A method and a device for fixing and synchronising rotary pistons in a rotary piston pump are disclosed. The rotary pistons are introduced into the pump space of the rotary piston pump. A shaft stub of each rotary piston is then pushed through a pump rear wall onto a driveshaft provided for the respective rotary piston. The rotary pistons are aligned and synchronised in the pump space by means of a template, the template being fixed detachably to a pump housing. The shaft stubs of the respective rotary piston are connected, after the synchronisation, in each case by means of a clamping device in a friction-locked manner to the respective driveshaft, outside the pump space.

Abstract: The invention relates to an eccentric screw pump and a method for its operation. Unlike the previously known prior art, where changes to the internal geometry of the pump stator caused by wear were always remedied with radially acting clamping measures, the invention is based on bringing this about by a change in the length of the lining.

Abstract: The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180° relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.

CPC classification number: F04C2/1075
Abstract: The stator comprises a rigid tubular casing and an elastic lining which is tightly enclosed by the casing and symmetrical with respect to the longitudinal center axis of the stator. The inner surface of the lining forms a multiple thread and, in cross section, consists of a number of sections near the axis equal to the number of courses of the thread and an equally great number of concave arcs. The lining has a minimum thickness each at the concave arcs and a maximum thickness each near at least two of the transitions between the sections near the axis and the concave arcs.
Abstract translation: 定子包括刚性管状壳体和弹性衬里，其被壳体紧密地包围并相对于定子的纵向中心轴对称。 衬里的内表面形成多个螺纹，并且在横截面中由靠近轴线的多个部分组成，等于线程的数目和等量的凹弧。 衬里在凹弧处具有最小厚度，最大厚度分别靠近轴线和凹弧之间的部分之间的至少两个过渡部分。
