Abstract

The invention discloses a deep sea oil-charging motor capable of automatically removing water, and the motor comprises a motor body and a water removing system connected with the motor body. A side, far from an output shaft, of a rotor of the motor body is provided with an axial hole and a radial hole, so as to generate pressure difference in the axial and radial directions when the rotor rotates. The water removing system comprises an oil incoming pipe, an oil outgoing pipe, and a water removing unit, so as to enable oil liquid to circulate in the water removing system when the motor operates, thereby removing the water in the oil liquid. The motor provided by the invention can remove seawater in the oil liquid, increases the underwater working time, and is simple and reliable in structure.

Description

technical field [0001] The invention relates to the field of motors, in particular to a deep-sea oil-filled motor for automatic water removal and a water removal method using the motor. Background technique [0002] The current deep-sea oil-filled motor uses the method of filling the inside of the motor with a closed casing with transformer oil to achieve the following purposes: [0003] 1. The internal oil pressure resists the external seawater pressure to prevent seawater from entering the motor and corroding the motor core and windings, so that the motor can work in places with large water depths; [0004] 2. The oil can accelerate the heat dissipation well, so that the motor has high power and small volume; [0005] 3. The oil can lubricate the bearing. [0006] Deep-sea oil-filled motors operate in water for a long time, and seawater may seep into the motor, causing the internal oil pressure of the motor to be emulsified with water, resulting in reduced insulation and...
