WELL PUMP WITH SEAL SECTION HAVING A LABYRINTH FLOW PATH IN A METAL BELLOWS |
摘要 |
A submersible well pump assembly has a rotary pump, a motor, and a seal section coupled between the motor and the pump. The seal section has a cylindrical housing having upper and lower adapter and a shaft extending axially through the housing. A guide tube surrounds the shaft and a bellows surrounds the guide tube. A well fluid passage communicates well fluid to a well fluid chamber between the bellows and the housing. A guide tube passage extends axially within the guide tube between an interior and an exterior of the guide tube from an upper portion to a lower portion of the guide tube for communicating lubricant in the motor with lubricant within the bellows. |
