Description

Sealing gasket for engine oil pan

Technical Field

The utility model relates to a gasket technical field specifically is an engine oil pan seal gasket.

Background

The engine oil pan is the lower half of the crankcase, also known as the lower crankcase. The function of the device is to close the crankcase as the shell of the oil storage tank, collect and store the lubricating oil flowing back from each friction surface of the diesel engine, dissipate part of the heat and prevent the lubricating oil from being oxidized. A gasket is typically required to seal between the engine oil pan and the engine block. In the assembling process, the sealing gasket can be extruded by the oil pan and the engine cylinder body in the up-down direction to deform, so that a gap between the oil pan and the engine cylinder body is filled, and the sealing effect is achieved.

The gasket seal plays an important role in modern industry, and the phenomena of seepage, overflow, dripping, leakage and the like can be caused by the failure of the seal, so that the performance of parts is seriously influenced. If the sealing is not good, the failure of the parts can be caused and even serious accidents can be caused. According to the traditional engine oil pan gasket sealing structure, the top surface of the oil pan gasket is a flat and straight sealing surface generally, and the oil pan gasket with the structure is easy to wear a shell due to the fact that the shell is not positioned when the oil pan gasket is used, so that the shell is worn and scrapped quickly.
