Engine oil flow configuration method for lubricating system for throwing boat diesel engine

Abstract

The invention provides an engine oil flow configuration method for a lubricating system for a throwing boat diesel engine. The diesel engine is controlled to be fully lubricated in the throwing state, namely an intercepting pipe is configured to an oil suction line of a lubricating pump, and an oil inlet line of the lubricating pump is configured to the oil inlet line of an oil suction opening, a flexible oil pipe, an oil inlet valve, the intercepting pipe, a sub manifold block and the lubricating pump oil inlet end. An oil outlet line of the lubricating pump is configured to the oil outlet line of the lubricating pump oil outlet end, the sub manifold block, a machine filtering device, the sub manifold block and a main oil way. Before the engine oil enters the machine filtering device, an overflow valve is arranged in the sub manifold block; it is guaranteed that the engine oil pressure of the main oil way ranges from 0.25 Pa to 0.3 Pa under the rated speed of the diesel engine, the opening of the oil inlet valve is reduced, and the continuous overflow rate of an overflow opening of the overflow valve is maintained within the range of 1-2 L / min; and after it is verified that the engine oil pressure of the diesel engine is not smaller than 0.05 MPa in the idling state, the drift diameter of the intercepting pipe is designed according to the opening of the oil inlet valve, the engine oil pressure of the diesel engine in the rated speed and idling state is verified again, and the waste of resources is avoided.

Description

technical field [0001] The invention relates to a method for configuring oil flow in a lubricating system of a diesel engine, in particular to a method for configuring the oil flow in a lubricating system for a diesel engine of a dropship, 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 will start to ignite after the lifeboat enters the water and automatically righting, which will waste some precious lifesaving time, thus restricting the rapid performance of the drop-off lifeboat. [0003] At present, in the diesel engine lubrication system of jettisoned boats, when the lifeboat is turned upside down, not only the diesel engine can only turn around t...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to overcome the diesel engine lubrication system of the existing inverted non-stop lifeboat, which can only be turned horizontally, but not vertically, and when the diesel engine is turned over, it will cause oil leakage pollution; Many, resulting in waste of resources and other issues
