SYSTEM AND METHOD FOR ABSORBING THE EXPANSION AND CONTRACTION OF INTERNAL FLUIDS OF A SUBMERGIBLE ELECTRIC MOTOR |
摘要 |
A motor protector for use in protecting an electric motor in a subterranean environment. The motor protector utilizes a dual chamber system for absorbing the expansion and contraction of the internal fluids of a submergible electric motor. One of the chambers provides for the expansion and contraction of the internal fluids of a submergible electric motor. The other chamber is in fluid communication with the subterranean environment. A gas pocket is disposed within the motor protector between and in fluid communication with both of the dual chambers. The volume of gas couples the fluid pressure of the subterranean environment to the internal fluids of the electric motor without direct contact between the internal fluids of the electric motor and fluids from the subterranean environment.
