Drum-type efficient diesel engine oil-gas separator

A technology for oil and gas separators and diesel engines, which is applied in the directions of machines/engines, mechanical equipment, engine components, etc., which can solve the problem of not being able to automatically adjust to ensure separation effect and pressure loss, limiting the versatility of different models and product series production, oil and gas separation. The position of the outlet of the device cannot be adjusted, which can increase the cost and manufacturing difficulty, avoid excessive air pressure loss, and avoid poor oil return.

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0040] A drum-type high-efficiency diesel engine oil-gas separator includes an upper filter assembly and a lower filter assembly. Such as figure 1 As shown, during installation, the upper filter assembly and the lower filter assembly are rotatably connected, and after being adjusted to a suitable position, the relative positions of the upper filter assembly and the lower filter assembly are fixed by means of welding, bolts, etc.

[0041] Such as figure 2 and image 3 As shown, the upper separation assembly includes an upper casing 1 and an upper filter part. The upper casing 1 is a cylindrical casing with a closed upper end surface and an open lower end surface, and an air intake duct 2 is fixedly connected to the side end surface, and the air intake duct 2 runs through the inner cavity of the upper housing 1 .

[0042] The upper fil...

Abstract

The invention belongs to the technical field of diesel engine oil-gas separation devices, and particularly relates to a drum-type efficient diesel engine oil-gas separator, an upper filtering assembly and a lower filtering assembly are designed in a separated mode, under the condition that a mold does not need to be redesigned, cost does not need to be increased and manufacturing difficulty does not need to be increased, the positions of a gas inlet pipeline and a gas outlet pipeline can be adjusted according to diesel engine space layout, the mounting requirement is met, a first filtering cavity, a second filtering cavity and a one-way valve assembly are used in cooperation, the airflow direction can be automatically adjusted according to the blow-by amount, and the pressure loss and the separation effect under the condition of various blow-by amounts are guaranteed; and an oil return hole and an oil return channel are independently arranged, so that unsmooth oil return is avoided, engine oil is prevented from being accumulated and brought out of an air outlet by airflow, and the engine oil can be effectively collected and reflowed. According to the drum-type efficient diesel engine separator, the problems that in the prior art, the position of an outlet of an oil-gas separator cannot be adjusted, universality of different types and series production of products are limited, and automatic adjustment cannot be conducted according to the blow-by amount to guarantee the separation effect and pressure loss are solved.

Description

technical field [0001] The invention belongs to the technical field of oil-gas separation devices for diesel engines, and in particular relates to a drum-type high-efficiency diesel engine oil-gas separator. Background technique [0002] The main emissions of the diesel engine are NOx and soot; when the diesel engine is working, some high-temperature and high-pressure gas leaks into the crankcase through the piston ring, which makes the oil in the crankcase oil pan thinner and the performance deteriorates. After the separator, the harmful gas in the crankcase can be discharged and the engine oil can be recovered to prolong the service life of the engine oil and save the engine oil. [0003] At present, the valve chamber cover of many diesel engines is equipped with an external integrated oil-gas separator. After the oil-gas separator is integrated into the valve chamber cover, the orientation of the air outlet of the oil-air separator is determined and unique; if the directi...
