Description

Technical Field

[0001] The present invention relates to the technical field of sealing test, and in particular to a sealing test device for oil pan production and a use method thereof. Background Art

[0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to seal the crankcase and act as an oil reservoir, preventing impurities from entering. It also collects and stores lubricating oil returning from the engine's friction surfaces, dissipating some of the heat and preventing lubricating oil oxidation. Located at the bottom of the engine, the removable oil pan seals the crankcase and acts as an oil reservoir. Oil pans are often stamped from thin steel sheets, while more complex shapes are typically cast from cast iron or aluminum alloy. An internal oil stabilization baffle prevents oil surface oscillation and splashing caused by engine turbulence, facilitating the settling of impurities. A dipstick is mounted on the side for checking the oil level. A drain plug is also installed at the lowest point of the oil pan. Most vehicles on the market have a wet oil pan, so-called because the crankshaft throw and connecting rod big end are immersed in the oil in the oil pan once per crankshaft rotation, providing lubrication.

[0003] Existing oil pans need to undergo airtightness tests during production to detect the sealing of the oil pan and avoid oil leakage during use. Currently, the sealing test equipment used for oil pan production on the market has a single function and cannot well simulate the sealing condition of the oil pan during use, which affects the service life of traffic lights.
