ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a fluid flow enhancing device. More particularly, but not by way of limitation, the invention relates to a fluid lifting device for use in lifting fluids from wells.
2. Related Art
There exist a large number and variety of fluid lifting devices for aiding fluid flow. Common to many of these devices are a pipe with some internal means for driving fluid in a desired direction. The driving means have included pumps, motor driven bowl and impeller devices and air.
While these prior devices attempted to improve fluid flow, for example in a well, there remains a need to provide a more efficient device for enhancing fluid flow. Accordingly, the present invention improves upon the art of enhancing fluid flow within a pipe and particularly lifting fluids from a well.
BRIEF SUMMARY OF THE INVENTION
It is an object to enhance fluid flow through conduits.
It is another object to enhance fluid flow and lifting fluid from wells.
It is another object to provide a device in a well for enhancing fluid flow therefrom and harness energy from the fluid flow to further enhance the fluid flow.
It is another object to utilize the fluid flow pressure from a well for lifting the fluid in an improved economical manner without the need for the present energy required by conventional reciprocating or turbine pumps.
Accordingly, the present invention is directed to a device for enhancing fluid flow in a well, which includes a housing, a first inlet in the housing to receive a propellant, a first chamber within the housing communicating with the first inlet, a first one way check valve disposed in the housing in a manner to permit communication from the first inlet to the first chamber, means for biasing the first one way check valve closed until reaching a first predetermined pressure of the propellant, a second chamber in the housing generally axially aligned with the first chamber, and a shaft bored surface interconnecting the first and the second chamber.
Further, a shaft is rotatably disposed within the shaft bored surface and extending from the first chamber to the second chamber, means for sealing about the shaft to prevent communication between the first chamber and the second chamber, a rotor rotatably mounted within the first chamber and fixably connected to the shaft, a first exit channel within the housing connected to the first chamber, an outlet in the housing communicating with the first exit channel, a second one way check valve disposed in the housing in a manner to permit communication from the first exit channel to the outlet, a second inlet in the housing communicating with the second chamber to permit receipt oil fluids from the well therein, and a second exit channel within the housing interconnecting the second chamber with the outlet.
Also, a pump impeller rotor rotatably mounted within the second chamber and fixably connected to the shaft in a manner to aid fluid flow from the second inlet to the second exit channel, a third one way check valve disposed in the housing, in a manner to permit communication from the second exit channel through to the outlet, and means for biasing the first one way check valve closed until reaching a first predetermined pressure of the fluid from the well.
In a preferred embodiment the propellant is air. The device further includes a fluid/air separator operably disposed downstream from the outlet in a manner to receive the fluid/air and separate the air and fluid.
Other objects and advantages will be readily apparent to those skilled in the art upon viewing the drawings and reading the detailed description hereafter.
