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 said impeller diameter as a speed of said rotating fluid or gas pump increases and decreasing the impeller diameter as the speed decreases. An extendable vane mechanism is configured to move along an elongated curved or sloping slot, said movement along the elongated curved or sloping slot is operable for increasing and decreasing a diameter of the impeller device. A spring mechanism having a first end and a second end extends and retracts to dynamically increase or decrease a diameter of the impeller device.
Claims20
A system comprising:
- an impeller device, in which said impeller device comprises a variable diameter impeller of a centrifugal pump, wherein said variable diameter impeller is configured to increase or decrease a flow of fluid from said centrifugal pump;
- a housing structure, wherein said housing structure is configured to enclose said centrifugal pump impeller device, and wherein said housing structure is further configured to surround said impeller device and contain said fluid;
- an extendable vane mechanism, in which said extendable vane mechanism comprises at least five or more extendable vanes, wherein said extendable vane mechanism is configured to extend outward to increase said fluid flow or retract inwards to reduce said fluid flow;
- a fixed vane mechanism, in which said fixed vane mechanism comprises at least five or more fixed vanes, wherein said extendable vane mechanism is configured to follow a contour of said fixed vane mechanism, and wherein said fixed vane mechanism is further configured to become an extension of said extendable vane mechanism;
- a first engagement means, in which said first engagement means comprises at least one of, a long threaded hollow or solid screw and a long threaded hollow or solid bolt, wherein said first engagement means is configured to connect said extendable vane mechanism to said housing and engage said extendable vane mechanism within an elongated curved slot;
- an opening portion disposed in each of said five or more extendable vanes, wherein said opening portion of each of said five or more extendable vanes is configured to allow fluid pumped through said centrifugal pump, to pass;
- an elongated slot implement disposed in said housing structure, in which said elongated slot implement comprises a curved or sloping slot, wherein said elongated curved or sloping slot is configured to engage said first engagement means, and wherein said extendable vane mechanism is configured to move along said elongated curved or sloping slot, said movement along said elongated curved or sloping slot is operable for increasing and decreasing a diameter of said impeller device;
- and
- a spring mechanism having a first end and a second end that extends and retracts, in which said spring mechanism is into engagement with said first engagement means and a second engagement means.

A system consisting of:
- means for reducing an energy consumption of a centrifugal pump by increasing a diameter of said energy consumption reducing means as a speed of a fluid flow from said centrifugal pump increases and decreasing said diameter as the speed of said fluid flow decreases;
- means for enclosing said energy consumption reducing means, wherein said enclosing means surrounds said energy consumption reducing means, in which said enclosing means includes means for engaging a motor driven shaft, means for securing said motor driven shaft in a predetermined orientation, and means for equalizing fluid pressure;
- means for increasing or decreasing a diameter of said energy consumption reducing means;
- means for connecting said diameter increasing or extending means to said enclosing means;
- means for providing a path for said diameter increasing or extending means to move, wherein a movement of said diameter increasing or extending means is operable for increasing and decreasing a diameter of said impeller device;
- means for extending and retracting said diameter increasing or extending means;
- and
- means for allowing a portion of said fluid to pass while substantially limiting additional restriction on fluid flow.
5 more elements
A system comprising:
- an impeller device, in which said impeller device comprises an impeller of a centrifugal pump, wherein a diameter of said impeller is configured to increase or decrease based on a flow speed of said fluid from said centrifugal pump;
- a housing structure, wherein said housing structure is configured to enclose said impeller device;
- a fixed vane mechanism, wherein said fixed vane mechanism comprises a contoured vane;
- an extendable vane mechanism, wherein said extendable vane mechanism is configured to follow said predetermined contour, and wherein said fixed vane mechanism is configured to become an extension of said extendable vane mechanism, said extension being operable for increasing said diameter of said impeller device;
- an opening portion disposed in a center section of said extendable vane mechanism, wherein said opening portion is configured to allow fluid pumped by said centrifugal pump, to pass;
- a first engagement means, in which said first engagement means comprises at least one of, a long threaded hollow or solid screw and a long threaded hollow or solid bolt, wherein said first engagement means is configured to connect said extendable vane mechanism to said housing structure;
- an elongated slot implement disposed in said housing structure, in which said elongated slot implement comprises a curved or sloping slot, wherein said elongated curved or sloping slot is configured to engage said first engagement means, and wherein said extendable vane mechanism is configured to move along said elongated curved or sloping slot, said movement along said elongated curved or sloping slot is operable for increasing and decreasing a diameter of said impeller device;
- a second engagement means, in which said second engagement means comprises at least a short threaded hollow screw, wherein said second engagement means is configured to connect said second end of said spring mechanism to said housing structure;
- and
- a spring mechanism having a first end and a second end that extends and retracts, in which said spring mechanism is into engagement with said first and second engagement means to dynamically increase or decrease a diameter of said impeller device.
