Abstract

A marine fuel oil supply device comprises an oil mixing barrel, an oil cabinet and a master control system. An oil mixing pipeline is arranged between the oil mixing barrel and the oil cabinet. An oil supply pipeline is arranged between the oil mixing barrel and an engine, and the oil mixing pipeline is provided with a first oil supply electric control valve, a filter, a supply oil pump and a flow meter. The oil supply pipeline is provided with an oil supply pressurizing oil pump, a second oil supply electric control valve and a viscometer. A heating device and a cooling device are further connected between the second oil supply electric control valve and the viscometer in parallel. The master control system comprises a CPU. The oil mixing barrel, the first oil supply electric control valve, the supply oil pump, the flow meter, the oil supply pressurizing oil pump, the second oil supply electric control valve and the viscometer are connected with the CPU through signal lines. The invention further provides a marine fuel oil supply method. By means of the marine fuel oil supply device and method, heavy oil or diesel oil or gas oil is provided for a power generator of a ship, the fuel oil amount, pressure and viscosity can be adjusted according to needs, and the marine fuel oil supply device and method have the beneficial effects that the fuel oil quality is improved, the fuel oil efficiency is improved, the fuel oil cost is reduced, and the engine is better protected.

Description

technical field [0001] The invention relates to marine equipment, in particular to a marine fuel oil supply device and method. Background technique [0002] The power engine of the main engine in a large ship mainly uses gas oil, diesel oil and heavy oil as fuel, and the oil supply devices of the three kinds of oil are scattered in various positions of the engine room. Devices cannot be controlled cooperatively as a whole device. Its main defects are as follows: [0003] (1) The control method is old and the control effect is not good. [0004] (2) The degree of automation is not high, and it is impossible to respond in time, which affects the operating efficiency of the entire system. [0005] (3) The control is relatively scattered, and it is easy to operate incorrectly. [0006] (4) The pressure and viscosity values ​​of different oils cannot be provided to the engine according to a unified standard. Contents of the invention [0007] The technical problem to be so...
