Fallback bearing protection system |
abstract |
An electrical submersible pump comprising a fallback bearing protection system, the system comprising: locking member; boot pivotally connected to shaft of electrical submersible pump adjacent to locking member, wherein the boot comprises a sloped outer wall capable of forming a fluid boundary thereby diverting fallback fluid away from uppermost bearing of electrical submersible pump; ridge disposed on the sloped outer wall of the boot. A method for protecting uppermost bearings of electrical submersible pump, the method comprising: operating the electrical submersible pump; removing power supply from electrical submersible pump; allowing fallback fluid to flow from a tubing disposed above electrical submersible pump into the electrical submersible pump thereby rotating fallback bearing protection system pivotally connected to shaft within electrical submersible pump; allowing the rotating fallback bearing protection system to create a fluid boundary capable of radially diverting the fallback fluid away from uppermost bearings of the electrical submersible pump. |
