Beschreibung
Zusammenfassung:	The invention provides a deep-sea mining lifting electric pump. The deep-sea mining lifting electric pump comprises a first pump, a double-output-shaft submersible motor and a second pump, the first pump is installed at the first output end of the double-output-shaft submersible motor, the second pump is installed at the second output end of the double-output-shaft submersible motor, a first output shaft located at the first output end is connected with a first pump shaft of the first pump and used for driving the first pump shaft to generate first axial force, and a second output shaft located at the second output end is connected with a second pump shaft of the second pump and used for driving the second pump shaft to generate second axial force opposite to the first axial force in direction. According to the technical scheme, due to the fact that the direction of the first axial force generated on the first pump is opposite to the direction of the second axial force generated on the second pump, the total
