Abstract
High pressure magnetic coupling shrouds and methods of producing the same are disclosed herein. An example shroud disclosed herein includes an inner shell including a thermoplastic composite or a metal, and an outer shell including a composite material.
Claims19
A shroud for a fluid pump comprising:
- an inner shell including a thermoplastic composite;
- and
- an outer shell including an inner radial surface directly coupled to an outer radial surface of the thermoplastic composite, the outer shell including a composite material, wherein the outer shell includes a thickness between 25 mils and 125 mils.
A magnetically driven pump comprising:
- a first shaft;
- a second shaft at least partially positioned around the first shaft, the second shaft magnetically engaged with the first shaft;
- and
- a shroud positioned between the first shaft and the second shaft, the shroud including:
- a composite shell, wherein the composite shell includes fibers positioned in a first orientation, a second orientation different from the first orientation, a third orientation different from the first orientation and the second orientation, and a fourth orientation different from the first orientation, the second orientation, and the third orientation, wherein the composite shell includes a thickness between 25 mils and 125 mils;
- and
- a liner including an outer radial surface in contact with an inner radial surface of the composite shell, the liner including a thermoplastic.
4 more elements
A shroud for a canned motor pump, the shroud comprising:
- a composite shell including first fibers in a first orientation and second fibers in a second orientation, wherein the composite shell includes a thickness between 25 mils and 125 mils;
- and
- an inner shell including an outer radial surface in contact with an inner radial surface of the composite shell, the inner shell including a thermoplastic.
