Peristaltic Submersible Pump

摘要

A system for displacing fluid inside of a tubular member includes at least one peristaltic pump. Each peristaltic pump includes an elongated core member with a longitudinal axis located within the tubular member. A flexible member surrounds, and is concentric to, the elongated core member. The flexible member has a plurality of circular bands disposed along a length of the flexible member, each circular band being moveable between a contracted condition with a minimal radius and an expanded condition with a maximal radius. An outer membrane covers the circular bands, forming a first fluid cavity between an outer surface of the outer membrane and an inner surface of the tubular member. The outer membrane is operable to generate peristaltic waves in the first fluid cavity by selectively moving each circular band between the contracted condition and the expanded condition.

1. A system for displacing fluid inside of a tubular member, the system comprising at least one peristaltic pump, each of the at least one peristaltic pumps comprising:
an elongated core member with a longitudinal axis located within the tubular member; a flexible member surrounding and concentric to the elongated core member, the flexible member comprising a plurality of circular bands disposed along a length of the flexible member, each of the circular bands being moveable between a contracted condition with a minimal radius and an expanded condition with a maximal radius; and an outer membrane covering the circular bands and forming a first fluid cavity between an outer surface of the outer membrane and an inner surface of the tubular member, the outer membrane operable to generate peristaltic waves in the first fluid cavity in response to selectively moving each of the circular bands between the contracted condition and the expanded condition.
