摘要： A pump has a thrust bearing has a casing with an inlet port and a discharge port. A shaft is positioned within the pump. A thrust bearing is coupled to the shaft. A pressure alterable bearing cavity is located within the casing. The pressure alterable cavity allows the axial thrust on the shaft from the impellers to be counteracted. The thrust bearing has an annular seal coupled with respect to the casing disc is coupled to the shaft and positioned adjacent the seal. The seal and the disc have a gap therebetween. A feedback pipe couples the bearing cavity to the inlet port. As the axial thrust acting on the shaft changes, the gap between the seal and the disc also changes. The changing of the gap changes the pressure within the bearing cavity. The disc and thus the shaft are repositioned in response to the change in the bearing cavity pressure change.

摘要： The invention is directed to an energy recovery pump turbine for use in industrial processes where a fluid is pumped at a high pressure to the process and at least a portion of the fluid is discharged from the process at a high pressure. A turbine is positioned to receive the high pressure discharge from the process. The turbine has an impeller positioned on a shaft and the discharged fluid engages the impeller and causes the impeller and shaft to rotate. A pump is position adjacent to the turbine to receive the fluid being pumped to the process. The pump has an impeller mounted on a shaft and the shaft of the pump is operatively connected to the shaft of the turbine. Rotation of the turbine shaft causes the impeller and the shaft of the pump to rotate whereby the pump assists in supplying the fluid under pressure to the process and to recover energy from the high pressure fluid discharged from the process.Also disclosed is a method for recovering energy from an industrial process where a fluid is pumped at a high pressure into the process and at least a portion of the fluid is discharged from the process at a high pressure. The high pressure discharged fluid is directed into the inlet of a turbine. The inlet of the turbine is caused to rotate by the high pressure discharged fluid. The turbine impeller is mounted on a rotatable shaft. An impeller of a pump that is mounted on the shaft is caused to rotate by the rotation of the shaft that is caused by the rotation of the turbine impeller. The fluid that is to be pumped to the process is directed to the inlet of the pump. The rotating impeller of the pump raises the pressure of the fluid supplied under high pressure to the process and recovers energy from the high pressure fluid discharged from the process.

摘要： An idler disk for reducing fluid drag forces in a machine having a rotating component is disclosed. An outer housing is provided for the machine and a cavity is defined in the outer housing. The cavity has opposed side walls. A rotatable component is positioned in the cavity and the rotatable component is spaced apart from the side walls of the cavity. At least one freely rotatable idler disk is positioned in the cavity and the idler disk is in spaced apart relationship with the rotatable component and the side walls of the cavity. The idler disk extends in the cavity along at least a portion of the length of the rotatable component. The idler disk is caused to rotate in the same direction as the rotatable component by the rotating fluid in the cavity. The fluid is caused to rotate by the rotation of the rotatable component. The rotating idler disk increases the speed of the fluid rotating adjacent the rotatable component and thereby reduces the fluid drag on the rotatable component. An outer seal means forms a seal between the idler disk and the rotatable component to control the flow of fluid between the idler disk and the rotatable component. The outer seal means is positioned adjacent the outer periphery of the rotatable component and the idler disk. The outer seal means acts to equalize the axial forces on the sides of the idler disk to maintain the idler disk in a desired equilibrium position where the idler disk is maintained in spaced apart relationship from the rotatable component and the side walls of the cavity.
