Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separation filter elements, in particular to a novel centrifugal oil mist separation filter element. Background Art

[0002] The principle of the oil-gas separator is that the exhaust gas discharged by the engine passes through the separator to separate the oil and other impurities in it, and the separated gas is returned to the engine for use or discharged into the atmosphere (playing an environmental protection role). The oil-gas separator is part of the exhaust gas circulation system. It is an independent pipeline from the oil pan to the engine intake hole. Its function is to decompose the oil vapor in the oil pan and the water vapor coming out of the combustion chamber. The separated oil film flows along the pipe wall to the oil pan, and the filtered steam enters the engine to burn again. The oil-gas separator is generally installed at the engine crankcase breathing port or the exhaust pipe. It is to separate the oil in the crankcase exhaust gas and reduce the oil discharged from the crankcase breathing port to the outside of the engine.

[0003] The existing centrifugal oil mist separation filter element has a significant problem of inconvenient assembly. The traditional centrifugal oil mist separation filter element is complex in design, which increases the difficulty of installation and reduces work efficiency. Due to the complex design, expensive materials and complex processing technology are required in the production process, resulting in high production costs. On the other hand, due to the inconvenience of assembly, a large amount of manpower and time costs are required during the installation and maintenance process, further increasing the total cost. Therefore, a new centrifugal oil mist separation filter element is proposed. Utility Model Content
