What is the function of liquid seal?

The liquid seal of the gasoline in the fuel tank can prevent the gasoline from volatilizing, so that the gasoline will not be consumed quickly due to excessive volatilization. After the liquid seal, the gasoline can also be prevented from leaking out, resulting in engine failure. Liquid sealing refers to the use of liquid to form a sealed state. The liquid seal of gasoline can also be called oil seal. Oil seal is a mechanical part used to seal gasoline, which separates the part of transmission that needs lubrication from the contributing part, so that lubricating oil is not easy to penetrate. Rubber commonly used for oil seal includes silicone rubber, polyurethane and so on. When selecting the oil seal material, we should consider the compatibility of the material with the working medium and the adaptability to the ambient temperature. Automobile oil seal generally appears in the engine, and the crankshaft, throttle, transmission and camshaft of the engine need to be used. Million car purchase subsidy
