Abstract

The invention discloses a floating type variable cross-section impeller structure in an oil-gas separation system. The impeller comprises a rotating shaft and a plurality of blades uniformly arranged along the circumference of the rotating shaft, wherein the blades are variable-section blades of which the widths are gradually changed along the axial direction of the rotating shaft. The impeller structure with the blades gradually changing in width in the axial direction of the rotating shaft is simple in structure and convenient to manufacture, and when the impeller structure is applied to a floating type oil-gas separation system, the contact area of the blades of the impeller structure and engine oil is changed by controlling the position change of the impeller structure to achieve impeller rotating speed control. And the separation efficiency of the oil-gas separator is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to a floating variable-section impeller structure in an oil-gas separation system. Background technique [0002] When the engine is working, the high-pressure combustible mixture in the combustion chamber will more or less leak into the crankcase through the gap between the piston group and the cylinder, causing blow-by. The components of blow-by gas are unburned fuel gas, water vapor and exhaust gas, etc., which will dilute the engine oil, reduce the performance of the engine oil, and accelerate the oxidation and deterioration of the engine oil. Moisture condenses in the engine oil, which will form sludge and block the oil circuit; the acid gas in the exhaust gas will be mixed into the lubrication system, which will cause corrosion and accelerated wear of engine parts; blow-by gas will also cause the pressure of the crankcase to be too high and damage the cra...
