Engine sump assembly for ship

Abstract

The invention discloses an engine sump assembly for a ship. The engine sump assembly is an integral cold-rolled steel plate, and comprises the bottom surface and the front and back side faces of a sump, a first end plate and a second end plate, wherein integral cold-rolled steel plates are arranged on the left and right side faces of the first and second end plates. A sump flange is cast by an integral cold-rolled steel plate. In the sump, the integral cold-rolled steel plates are taken as the body and the end face of the sump, and longitudinal reinforcing ribs are uniformly arranged, so that the rigidity is enhanced, deformation difficultly occurs, the strength is high, welding seam connection is reduced, and the sump shape is improved. The amplitude of deformation occurring in the case of collision of the sump and the probability of failure of normal work of an engine oil pump are lowered. High toughness and high ductility are achieved, the shape of the sump is effectively fixed, the reliability and durability of the sump are enhanced, the machining process is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of engine accessories, in particular to a marine engine oil pan assembly. Background technique [0002] The oil sump is located at the bottom of the engine, and its function is to close the crankcase as the casing of the oil storage tank, prevent impurities from entering, and collect and store the lubricating oil flowed back by the friction surfaces of the diesel engine. [0003] In the prior art, the oil sump of a large marine engine is relatively large in size, and generally adopts a split welded structure: that is, the five oil retaining surfaces and flange surfaces of the oil sump are made separately and then connected together by welding. Therefore, the shape of the oil pan can only be a relatively regular rectangle. [0004] The oil pan adopts a split welding design, resulting in many welds in the oil pan, reduced overall strength, and complicated manufacturing process. The split welding design limits the shap...

[0004] The oil pan adopts split welding design, resulting in many welds in the oil pan, lower overall strength, and complicated manufacturing process

The split welding design limits the shape of the oil pan. Generally, it can only be rectangular and there is no gradient inside. When the operating condition is unstable, the collision deformation is large, resulting in the scrapping of the oil pan and the increase in the probability that the oil pump cannot absorb oil normally.
