Abstract

The invention discloses a multi-cylinder diesel engine lubricating system for a lifeboat. The lubricating system comprises an engine oil pump, a lubricating oil tank, a breathing tube, a machine body and an oil bottom shell, wherein the engine oil pump is a duplex pump with an oil inlet and an outlet which are separately independent, and is superposed up and down, the upper layer of the duplex pump is equipped with a lubricating pump and the lower layer of the duplex pump is equipped with an oil return pump; an oil inlet of the oil return pump extends to the bottom of an oil bottom shell mould cavity, and an oil outlet of the oil return pump extends to the lubricating oil tank; an oil inlet of the lubricating pump extends to the lubricating oil tank, an oil outlet of the lubricating pump extends to an inlet of a filter, and an outlet of the filter communicates with a machine body main oil path; a breathing one-way valve and an oil adding hole are arranged on an oil tank cover of the lubricating oil tank; an outlet of the breathing one-way valve communicates with one end of the breathing tube, and the other end of the breathing tube communicates with a crankcase; and meanwhile, an lubricating oil flow distributing method for a lifeboat diesel engine is set. According to the multi-cylinder diesel engine lubricating system disclosed by the invention, functions of collecting engine oil and storing the engine oil of an oil bottom shell of the lifeboat diesel engine are separated, so that the diesel engine can normally work regardless of being longitudinally and transversely turned over and reversed.

Description

technical field [0001] The invention relates to a diesel engine lubricating system, in particular to a multi-cylinder diesel engine lubricating system for a lifeboat, which enables the lifeboat to be dropped into water from a drop frame of a mother ship when the diesel engine is working, and belongs to the technical field of marine diesel engines. Background technique [0002] The lifeboat is dropped and released on the mother ship, which can greatly improve the lifesaving efficiency. This technology is paid more and more attention to and used by people. However, the main engine of the lifeboat is an inverted parking diesel engine, that is, the diesel engine starts to ignite after the lifeboat enters the water and automatically straightens, which will waste some precious lifesaving time, and thus restricts the rapid performance of the lifeboat when it is thrown into the water. [0003] At present, in the diesel engine lubrication system of an inverted non-stop lifeboat, whe...
