Abstract
A stator assembly for a progressing cavity pump is provided. The stator assembly includes a number of stator laminates having a planar body defining a primary, inner passage and a number of outer passages, the outer passages disposed effectively adjacent the inner passage whereby the inner passage is at least partially defined by a band, wherein the band is outwardly flexible. The stator laminates are coupled to each other in a stack wherein the stator laminate body inner passages define a helical passage. The helical passage is a flexible helical passage.
Claims12
A method of coupling laminates for making one or both of a rotor and a stator for a progressing cavity pump comprising:
- providing a number of unitary laminate bodies, each of the laminate body including a number of coupling components, a continuous perimeter edge surface and a number of passages disposed effectively adjacent the laminate body continuous perimeter edge surface;
- positioning a plurality of the laminate bodies in a coupling configuration;
- coupling each of the laminate body that is in said coupling configuration to at least one of the adjacent laminate body;
- wherein each of the laminate body coupling component is one of a fastening coupling component, an interference fit coupling component, or a compound coupling component;
- providing each of the laminate body with an elongated laminate body inner passage;
- determining the orientation of each of the laminate body inner passage;
- positioning a lower laminate body in a first orientation;
- positioning an upper laminate body in a second orientation wherein said second orientation is skewed relative to said first orientation;
- and
- disposing said upper and lower laminate bodies in a stack.
