る低温サブマージドモータポンプ。In a low-temperature submerged motor pump that uses part of the liquefied gas discharged from a pump driven by a motor to lubricate the bearings of the motor and cool the inside of the motor, when the internal pressure of the motor exceeds a first predetermined pressure, the inside and outside of the motor are communicated. and a gas vent valve that closes when the internal pressure of the motor exceeds a second predetermined pressure, and communicates between the inside and outside of the motor when the internal pressure of the motor exceeds a second predetermined pressure, so that the fluid pressure inside the motor is kept constant without allowing a predetermined flow rate to flow. A flow rate control valve is provided on the upper part of the motor, and the pump is configured as a multi-stage pump so that a part of the intermediate discharge liquefied gas of the pump is supplied from the lower part of the motor into the motor, and a part of the intermediate discharge liquefied gas of the pump is supplied into the motor. A low-temperature submerged motor pump characterized in that it is configured to supply a portion of the gas to a bearing of the motor.
