Marine integrated fuel oil-lubricating oil-sea water pump set device

Abstract

The invention discloses a marine integrated fuel oil-lubricating oil-sea water pump set device which comprises a motor, a speed reducer, a sea water pump, a fuel oil pump and a lubricating oil pump, output shafts of the sea water pump and the motor are fixedly connected with an input shaft of the speed reducer, and an output shaft of the speed reducer is coaxially connected with the fuel oil pump and the lubricating oil pump. According to the marine integrated fuel oil-lubricating oil-sea water pump set device, the technical problems that the number of configured fuel oil pumps is too large, the adaptability is poor, and operation is complex are solved, comprehensive integration of structures and functions of the fuel oil pumps, the lubricating oil pumps, the sea water pumps and the like is achieved, the utilization rate of cabin arrangement space can be increased, the battle positions of operators are reduced, and overall integration and construction, installation and building of a real ship system are facilitated.

Description

technical field [0001] The invention relates to the technical field of ship steam power system structure, in particular to a marine integrated fuel-lubricating oil-seawater pump set device. Background technique [0002] Gas turbines and diesel engines are the main power devices to ensure the propulsion and power generation of underwater ships. In order to ensure the normal operation of gas turbines and diesel engines, it is necessary for the actual ship to ensure the supply of heat resources and cooling resources provided by fuel pumps, lubricating oil pumps, and seawater pumps. Among them, the fuel pump provides fuel supply for gas turbine and diesel engine, the lubricating oil pump provides lubrication for mechanical power equipment, and the seawater pump provides cooling source for the unit. [0003] In the normal design of actual ships, each diesel engine and gas turbine unit will be equipped with fuel pumps, lubricating oil pumps and seawater pumps independently. For th...

AI Technical Summary

Problems solved by technology

[0003] In the normal design of actual ships, each diesel engine and gas turbine unit will be equipped with fuel pumps, lubricating oil pumps and seawater pumps independently. For the consideration of the reliability of the pump unit, each pump unit needs redundant backup, which makes the whole ship install a large number of Fuel pumps, lubricating oil pumps, and seawater pumps, considering the space constraints of the ship’s cabin, it is difficult to arrange a large number of fuel oil, lubricating oil, and seawater pumps, and it is more difficult to arrange the complex and large-sized oil-water connection pipelines. The installation process is difficult

At the same time, there are differences in the operation and operation modes of each type of pump set, which increases the number of crew members for operation and maintenance of the pump set accordingly

[0004] Therefore, in order to solve technical problems such as too many fuel, lubricating oil, and seawater pumps in a narrow marine environment, poor fitability, and complex operation, it is urgent to integrate fuel pumps, lubricating oil pumps, and seawater pumps. In terms of structure, it realizes the integration of functions and structures, reduces capacity and reduces weight, and realizes coordination of pumps and machines, reducing personnel and increasing efficiency in terms of operation, and also reserves technologies for the overall design of related underwater and underwater ship power systems.
