Embodiment Construction

[0030] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0031] This example figure 1 , figure 2 , image 3 As shown, a plastic oil-gas separator combining a labyrinth type and a spiral type, the shell 4 is a flat box structure formed by one-time injection molding, the inside of the shell 4 has a smooth surface, and the surface roughness value Ra≤0.08μm (The smooth surfaces mentioned in this technical solution are all the same). The circular card cover 1 on the outer end surface of the housing, the oil-gas separation membrane 2 is installed at the joint between the card cover 1 and the housing 4, and the oil-gas separation membrane 2 is also a one-time injection-molded disc-shaped structure, and there are distribution points on its width. Around the center of the circle, there are 12 long strip-shaped geometric protrusions with a semicircular cross-secti...

Abstract

The invention relates to a plastic oil and gas separator with the labyrinth type and the screw type combined in order to solve the problems that oil and gas separation efficiency can not be optimized, and the mixture of engine oil and gas can not be completely separated. The plastic oil and gas separator with the labyrinth type and the screw type combined comprises a shell and a clamping cover arranged on the end face of the shell and is characterized in that the shell is of a flat box type structure formed through one-time injection molding, and an oil and gas mixture inlet, an oil return cavity and an air separation cavity are all provided with smooth surfaces; the oil and gas mixture firstly passes through a labyrinth type channel and then passes through a fine separator assembly; the fine separator assembly is provided with a plurality of oil and gas separation holes with screw-type channels; the position where the clamping cover is matched with the shell is provided with an oil and gas separation diaphragm. The plastic oil and gas separator with the labyrinth type and the screw type combined is scientific and reasonable in structure and has good economic benefits and the environmental-friendly working effect, and separated matter can be recycled.

Description

technical field [0001] The invention relates to the technical field of automobile engine parts, in particular to a plastic oil-gas separator combining a labyrinth type and a spiral type, which can improve the oil-gas separation efficiency of the engine. Background technique [0002] At present, most domestic automobile engines use aluminum oil-gas separators, which are cast as a whole with aluminum alloy materials, and their advantages are relatively compact structure and high strength. However, the aluminum oil-gas separator also has objective defects, such as heavy weight; due to the process characteristics of aluminum casting, the design limitations of the separation method of the oil-gas separator are small, and the optimal separation method design scheme cannot be obtained; aluminum alloy casting The inner wall of the oil-gas separator is relatively rough, which leads to low efficiency of oil-gas separation; although a small number of automobile engines use plastic oil-...
