Abstract

The invention discloses a fuel oil leakage positioning system and a fuel oil leakage alarm system for a marine diesel engine. The positioning system comprises leaked oil branch pipes and leakage directing valves, wherein one end of each leaked oil branch pipe is connected to a position between the inner wall and the outer wall of one high-pressure fuel oil double-wall pipe of a diesel engine, and the other end of each leaked oil branch pipe is equipped with the corresponding leakage indicating valve; indication on a condition whether each leaked oil branch pipe has leaked oil or not is carried out by judging whether the valve element of each leakage indicating valve is ejected out or not, so that positioning for a fuel oil leaking part is realized. The alarm system comprises the positioning system. The invention discloses the fuel oil leakage positioning system and the fuel oil leakage alarm system. The leakage indicating valve is arranged in each branch pipe of each high-pressure fuel oil double-wall pipe, so that the leakage positioning function can be realized; and a leakage alarm device is arranged in a fuel oil recycling device, so that an alarm function is realized.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine operation security monitoring, in particular to a fuel oil leakage positioning system and an alarm system for a marine diesel engine. Background technique [0002] Current diesel engines are equipped with high-pressure fuel flow pipes, which are usually high-pressure fuel double-wall pipes, and the outer layer of the high-pressure fuel double-wall pipes receives fuel that may leak. When there is leaking fuel in the system, the leaking fuel flows into the outer tube of the high-pressure fuel double-wall piping. The existing high-pressure fuel oil double-wall pipe leakage alarm system generally collects the leakage oil from the high-pressure fuel pipes of each cylinder to the leakage oil main pipe, and connects a leakage alarm in series near the oil outlet of the leakage oil main pipe. Among them, the leakage alarm realizes the leakage alarm function through the oil collecting ta...
