Abstract
A system having a variable diameter impeller device that is operable for reducing an energy consumption of a rotating fluid or gas pump by increasing the impeller diameter as a speed of the rotating fluid or gas pump increases and decreasing the impeller diameter as the speed decreases. An extendable vane arrangement is configured to move along an elongated curved or sloping slot, the movement along the elongated curved or sloping slot is operable for increasing and decreasing a diameter of the impeller device. A spring arrangement having a first end and a second end extends and retracts to dynamically increase or decrease a diameter of the impeller device.
Claims17
A system comprising:
- an impeller device, in which said impeller device comprises a variable diameter impeller that is configured to be operable for controlling a flow of a fluid;
- a housing structure, wherein said housing structure is configured to enclose said impeller device;
- an extendable vane arrangement, in which said extendable vane arrangement comprises a plurality of extendable vanes, wherein each of said plurality of extendable vanes is configured to be operable for at least one of extending outward to increase said fluid flow and retracting inwards to reduce said fluid flow;
- a fixed vane arrangement, in which said fixed vane arrangement comprises a plurality of fixed vanes, wherein each of said plurality of fixed vanes comprises a contoured shape;
- wherein each of said plurality of extendable vanes is configured to follow said contour of each of said plurality of fixed vanes;
- wherein each of said plurality of fixed vanes is configured to become an extension of each of said plurality of extendable vanes;
- an elongated slot implement disposed in said housing structure, wherein said extendable vane arrangement is configured to move along a length of said elongated slot implement, and wherein said movement along said elongated slot implement is operable for supporting the extension or retraction of said extendable vane arrangement;
- and
- a spring arrangement, in which said spring arrangement is configured to be operable for extending or retracting said extendable vane arrangement.
A system comprising:
- an impeller device;
- a housing structure, wherein said housing structure is configured to enclose said impeller device;
- a fixed vane arrangement, wherein said fixed vane arrangement comprises a contoured shape;
- an extendable vane arrangement, wherein said extendable vane arrangement is configured to follow said contoured shape of said fixed vane arrangement, and wherein said fixed vane arrangement is configured to become an extension of said extendable vane arrangement;
- an elongated slot implement disposed in said housing structure, wherein said extendable vane arrangement is configured to move along a length of said elongated slot implement, and wherein said movement along said elongated slot implement is operable for at least one of increasing and decreasing said-a diameter of said impeller device;
- a first engagement means, wherein said first engagement means is configured to connect said extendable vane arrangement to said housing structure;
- a spring arrangement, in which said spring arrangement is configured to dynamically increase or decrease said diameter of said impeller device;
- and
- a second engagement means, wherein said second engagement means is configured to connect said spring arrangement to said housing structure.
