the output shafts of the sea water pump 4 and the motor 1 are fixedly connected with the input shaft of the speed reducer 3, and the output shaft of the speed reducer 3 is coaxially connected with the fuel pump 5 and the lubricating oil pump 6.
In this embodiment, the speed reducer 3 has a two-branch two-stage speed reduction structure. The marine integrated fuel-lubricating oil-seawater pump set device adopts a single-input and double-output pump set structure, a variable frequency motor 1 is used for directly driving a seawater pump 4 through a speed reducer 3 with double branch gears, and a fuel pump 5 and a lubricating oil pump 6 which are connected in series are driven after two-stage speed reduction through the speed reducer 3.
