Problems solved by technology

[0004] Since the working pressure in the crankcase will change during the working process of the crankcase, the oil-gas separator installed in the crankcase ventilation system cannot be adjusted according to the change of the working pressure in the crankcase. The pressure difference changes greatly, which affects the oil-gas separation effect of the oil-gas separator

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] Such as figure 1 As shown, a fine separation module of an oil-gas separator includes a fine separation shell 1, a fine separation pipeline 2 arranged in the fine separation shell, a fine separation cotton layer 3 positioned between the fine separation shell and the fine separation pipeline, and a fine separation cotton layer arranged in the fine separation shell. The self-adaptive pressure difference adjustment mechanism 4 in the separation pipeline.

[0028] The fine separation shell is a plastic shell. The lower part of the outer surface of the fine separation shell is provided with an oil return hole 1.1. The fine separation pipe is a plastic pipe. The fine separation shell and the fine separation pipeline are connected by a buckle. Several protrusions are arranged on the outer surface of the fine separation pipe.

[0029] The fin...

Abstract

The invention discloses a fine separation module of an oil-gas separator. According to the aim, the gas flow passing area of the oil-gas separator can be adjusted according to the change of work pressure in a crankcase, the differential pressure change of the oil-gas separator is reduced, and therefore the oil-gas separation effect is improved. The fine separation module comprises a fine separation shell, a fine separation pipeline arranged in the fine separation shell, a fine separation cotton layer located between the fine separation shell and the fine separation pipeline, and a self-adaption differential pressure adjusting mechanism arranged in the fine separation pipeline. The fine separation pipeline comprises a gas inlet section pipeline and a separation section pipeline, and a plurality of oil-gas via holes penetrating the inner side face and the outer side face of the separation section pipeline are formed in the separation section pipeline. The self-adaption differential pressure adjusting mechanism comprises a limiting block arranged on the inner side face of the separation section pipeline, a sealing ball arranged in the fine separation pipeline in a sliding manner and asealing ball pre-tightening compression spring arranged in the fine separation pipeline.

Description

technical field [0001] The invention relates to an oil-gas separator, in particular to a fine separation module of the oil-gas separator. Background technique [0002] When the engine is working, there is always a part of the oil gas of the combustible mixture and the exhaust gas that escapes into the crankcase through the piston ring. This part of the oil and gas escapes into the crankcase. On the other hand, this part of the oil gas that escapes into the crankcase will increase the pressure in the crankcase, and the oil will seep out from the crankshaft oil seal, crankcase gasket, etc. Large, resulting in loss of engine power. [0003] In order to prevent the loss of oil and gas into the atmosphere and increase the pollution to the atmosphere, an oil-gas separator is usually installed in the crankcase ventilation system at present, and the oil is separated from the exhaust gas through the oil-gas separator. On the one hand, the consumption of engine oil is reduced, on the...
