SYSTEM AND METHOD FOR PROTECTING A SUBMERGIBLE MOTOR FROM CORROSIVE AGENTS IN A SUBTERRANEAN ENVIRONMENT

摘要

A motor protector for use in protecting an electric motor in a subterrane an environment utilizes a dual, flexible bladder system. One of the expandable bladders 62 provides for the expansion and contraction of motor oil. The other expandabl e bladder 76 contains a supply of neutralizing solution 74. The bladder 76 filled with neutralizing solution 74 cooperates with the bladder 62 filled with motor oil to maintain the expandable bladder 62 bathed in neutralizing solution 74. This prevents migration of corrosive agents into the motor oil.
