Problems solved by technology

[0004] However, the method of making the oil pan deep or a single partial deep cavity can cope with a limited angle of engine inclination; and the single deep cavity oil pan is often at the front or at the rear due to matching reasons, and at this time only one can be solved. The problem of inclination of the direction; and the local deep pit of the oil pan will make the lower part of the engine protrude, and the height of the whole machine will increase, which will reduce the adaptability of the engine

Abstract

The invention discloses a dual-zone dual-pump wet sump system. The system is arranged in a sump body. The sump body comprises a first oil collecting zone and a second oil collecting zone, and the bottom of the first oil collecting zone and the bottom of the second oil collecting zone are lower than the bottom of other zones of the sump body. According to the dual-zone dual-pump wet sump system, due to the arrangement of the double oil collecting zones, and normal lubrication can be guaranteed when an engine is inclined due to bumpy road surface or water surface waves.

Description

technical field [0001] The invention relates to the field of engines, in particular to a wet oil sump system with two zones and two pumps. Background technique [0002] At present, the engine generally adopts a wet oil pan, which is generally assembled at the lower part of the engine. The oil pump draws lubricating oil from the oil pan through the oil suction plate to form a certain pressure. After filtering and cooling, it is sent to each lubrication node of the engine to complete the lubrication. Oil relies on gravity to return to the oil pan at the lower part of the engine to complete the cycle. [0003] During the working process of the walking machinery, the engine will tilt due to the ups and downs and the water waves of the ship, which will cause the relative position of the lubricating oil liquid level in the oil sump and the oil suction plate to change, which may cause the oil suction plate to be exposed to the liquid surface, causing the oil pump to pump The lubri...
