| titleOfInvention | Below motor pressure compensation system for submersible pump |
| abstract | ABSTRACT OF THE DISCLOSURE A submersible pump assembly has pressure compensator features to avoid negative pressure at the top of the tool during installation. The submersible pump assembly has an electric motor contained within a lubricant filled motor chamber below a pump. A pressure compensator chamber is located below the motor chamber and separated by a parti-tion. The pressure compensator chamber is also filled with lubricant. A passage bypasses the partition and leads to the motor chamber above the motor. A bellows is mounted in the pressure compensator chamber with its mouth facing upwardly. A port extends from the exter-ior of the pressure compensator chamber to the interior of the bellows for admitting well fluid. Also, the bel-lows may be filled with a heavy fluid during installation so as to retard contraction of the bellows if the tool is suddenly jerked to a stop. The bypass passage is not re-quired in this embodiment. |
