Jet pump system and method with improved efficency

Abstract

The present disclosure is of a jet pump system, and reverse power generation system and other desirable applications consisting of an impeller with inlet vortex vanes and outlet vortex vanes. The inlet vortex vane induces rotational movement on mass entering the impeller inlet. The outlet vortex vanes remove swirl from mass exiting the impeller outlet. Embodiments include a jet pump system involving a pulley and belt which can allow for obstruction free movement of mass. In another embodiment the impeller is connected via an electromagnetic connection. In another embodiment the impeller acts as a rim-driven generator of electrical power. In another embodiment the drive pulley is a centrifugal clutch or uses a chain sprocket or tandem jet system in series.

What is claimed is: 
     
         1 . A jet pump system comprising:
 an impeller,   inlet vortex vanes, and   outlet vortex vanes.   
     
     
         2 . The jet pump system of  claim 1  wherein the impeller is attached to a drive pulley by a belt and the drive pulley is in turn connected to the output shaft of a motor such that when the motor causes the output shaft to rotate the output shaft also causes the drive pulley to rotate which in turn causes the belt to move and which in turn rotates the impeller. 
     
     
         2 . The jet pump system of  claim 1  wherein the impeller is electromagnetically connected to a housing. 
     
     
         4 . The jet pump system of claim  3  wherein energy applied to the housing electromagnetically causes the impeller to rotate. 
     
     
         5 . The jet pump system of  claim 2  wherein the rotation of the impeller by the mass entering the impeller causes the housing to act as a generator of electrical power. 
     
     
         6 . The jet pump system of  claim 1  wherein the inlet vortex vanes of the impeller directs mass that enters the jet pump to an angle matching the optimal angle of blades of the impeller. 
     
     
         7 . The jet pump system of claim t wherein the inlet vortex vanes and the lack of an impeller shaft removes a flow obstruction to improve efficiency and removes the source of a flow disturbance caused by the obstruction so that a smooth mass flow strikes the impeller at an optimum angle of attack to create more thrust for a given impeller size and shape to motor output power ratio. 
     
     
         8 . The jet pump system of  claim 1  wherein the inlet vortex vanes of the impeller cause mass that enters the impeller to rotate in a direction that is opposite to the direction of rotation of the impeller. 
     
     
         9 . The jet pump system of  claim 1  wherein the outlet vortex vanes of the impeller increases the flow of the mass and reduces flow swirl at the exit the jet pump system. 
     
     
         10 . The jet pump system of  claim 1  wherein the outlet vortex vanes of the impeller are matched to the optimal angle of the impeller blades. 
     
     
         11 . The jet pump system of  claim 1  wherein the outlet vortex vanes of the impeller direct the trajectory of mass exiting the impeller to minimize swirl. 
     
     
         12 . The jet pump system of  claim 1  wherein the impeller is connected to an impeller housing by a bearing and a seal and a retaining device 
     
     
         13 . The jet pump system of  claim 1  wherein the output shaft of the motor is connected to the drive pulley by a centrifugal clutch or constant velocity transmission. 
     
     
         14 . A method of a jet pump system wherein the mass pumped by the jet pump system enters the jet pump system through inlet vortex vanes and then passes through an impeller and then passes through outlet vortex vanes to exit the jet pump system. 
     
     
         15 . The method of  claim 14  wherein the outlet vortex vanes remove swirl at the exit the jet pump system.
