PROTECTION SYSTEM FOR SUBMARINE SEA WATER INJECTION PUMPS

摘要

protection system for underwater seawater injection pumps the present invention relates to a pump system, especially for boosting the flow rate of a fluid through a pipe (1, 2, 6), comprising a pump positioned in a pump chamber (10) for pumping at a chosen rate, and a motor pulling that pump, the motor being positioned in a chamber (9) being provided with a pressurized fluid, the pressure of which being higher than the pressure in the pump chamber, the motor and the pump chambers being separated by a seal (8), the seal enabling a leakage of said pressurized fluid between them, in which the pressurized fluid is acceptable for the pump environment and the system comprises a line discharge branch (3) coupled to the pipe (6) and positioned downstream from said pump, the discharge branch line having an outlet for the environment.
