Abstract
A system can be used in a wellbore. The system can include a first thrust chamber, a second thrust chamber, and a seal guide. The first thrust chamber can include a first bearing for absorbing thrust in a first direction in the wellbore. The second thrust chamber can include a second bearing for absorbing thrust in a second direction in the wellbore that is different than the first direction. The seal guide can be positioned between the first thrust chamber and the second thrust chamber to separate the first thrust chamber from the second thrust chamber. The seal guide can protect the second thrust chamber and can provide radial support for a shaft that can be positioned in the first thrust chamber and the second thrust chamber.
Claims20
A system comprising:
- a first section of a thrust chamber comprising a first bearing for absorbing thrust in a first direction in a wellbore;
- a second section of the thrust chamber comprising a second bearing for absorbing thrust in a second direction in the wellbore that is different than the first direction;
- and
- a seal guide positionable between the first section and the second section to separate the first section from the second section, the seal guide for protecting the second section and for providing radial support for a shaft positionable in the thrust chamber, the first section spaced apart from the seal guide in the first direction along an axis to define a first volume sized to receive heat-dissipating fluid, the second section spaced apart from the seal guide in the second direction along the axis to define a second volume sized to receive the heat-dissipating fluid, the first volume extending from the shaft to an inner diameter of the first section and extending from the first bearing to the seal guide, and the second volume extending from the shaft to an inner diameter of the second section and extending from the second bearing to the seal guide.
A system comprising:
- a shaft positionable in a wellbore;
- a first section of a thrust chamber positionable around the shaft and comprising a first bearing for absorbing thrust in a first direction in the wellbore;
- a second section of the thrust chamber positionable around the shaft and comprising a second bearing for absorbing thrust in a second direction in the wellbore that is different than the first direction;
- and
- a seal guide positionable between the first section of the thrust chamber and the second section of the thrust chamber to separate the first section of the thrust chamber from the second section of the thrust chamber, the seal guide for protecting the second section of the thrust chamber and for providing radial support for the shaft, the first section of the thrust chamber spaced apart from the seal guide in the first direction along an axis to define a first volume sized to receive heat-dissipating fluid, the second section of the thrust chamber spaced apart from the seal guide in the second direction along the axis to define a second volume sized to receive the heat-dissipating fluid, the first volume extending from the shaft to an inner diameter of the first section and extending from the first bearing to the seal guide, and the second volume extending from the shaft to an inner diameter of the second section and extending from the second bearing to the seal guide.
A downhole pump comprising:
- a first section of a thrust chamber comprising a first bearing for absorbing thrust in a first direction in a wellbore;
- a second section of the thrust chamber comprising a second bearing for absorbing thrust in a second direction in the wellbore that is different than the first direction;
- and
- a seal guide positionable between the first section of the thrust chamber and the second section of the thrust chamber, the seal guide comprising an obstruction positionable around a shaft to separate the first section of the thrust chamber from the second section of the thrust chamber, the seal guide for protecting the second section of the thrust chamber and for providing radial support for the shaft that is positionable in the first section of the thrust chamber and the second section of the thrust chamber, the first section of the thrust chamber spaced apart from the seal guide in the first direction along an axis to define a first volume sized to receive heat-dissipating fluid, the second section of the thrust chamber spaced apart from the seal guide in the second direction along the axis to define a second volume sized to receive the heat-dissipating fluid, the first volume extending from the shaft to an inner diameter of the first section and extending from the first bearing to the seal guide, and the second volume extending from the shaft to an inner diameter of the second section and extending from the second bearing to the seal guide.
