Setting method of wet sump for diesel engine

Abstract

The invention discloses a setting method of a wet sump for a diesel engine. A filter screen body, a filter screen, a filter, a check valve, a lubricating oil sucking pipe, an oil separator suction pipe, an oil pre-supplying and pumping pipe, a cable pipe and a liquid level alarm device are arranged in the wet sump, wherein the liquid level alarm device is positioned at the central line position of a sump. The method comprises the following steps of: (1) determining the lowest liquid level Hmin and the highest liquid level Hman of the sump when the diesel engine is at a horizontal position; (2) calculating the alarm height h of the lubricating oil liquid level; (3) forming a longitudinal trim of 5 degrees when a user uses the wet sump, wherein when the alarm height of the lubricating oil liquid level is 313mm after being checked, the requirement of the longitudinal trim of 5 degrees can also be met by simulating the position of the lubricating oil liquid level; (4) calculating the depth H of the sump; and (5) setting result check. The practical requirements on use of ships provided by the user are met; and at the same time, the horizontal trim and the longitudinal trim of the highest liquid level are considered, so the diesel engine is still at a reliable working state under the conditions that the horizontal trim is 15 degrees and the longitudinal trim is 5 degrees.

Description

technical field [0001] The invention relates to a 16PA6STC diesel engine in a ship, in particular to a setting method for a wet oil pan of the 16PA6STC diesel engine. Background technique [0002] In the process of designing and building existing ships, more and more factors need to be considered, such as the actual situation of engine room space and height, etc. The dry oil pan used by diesel engines has been replaced by a wet oil pan, but the wet oil sump It is difficult to set the height of the lubricating oil level alarm device in the shell. Relevant background technologies may be supplemented. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, under the situation that does not affect the normal operation of diesel engine, provide a kind of wet oil sump setting method of diesel engine, make diesel engine in the situation of heeling 15 ° and pitching 5 ° Under this condition, a reliable ...
