A drum type high-efficiency diesel 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 further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] A drum-type high-efficiency diesel oil-gas separator includes an upper filter assembly and a lower filter assembly. like figure 1 As shown in the figure, during installation, the upper filter assembly and the lower filter assembly are rotated and 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 welding, bolts, etc.

[0041] like figure 2 and image 3 As shown, the upper separation assembly includes an upper housing 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 thereof, and the air intake duct 2 penetrates the inner cavity of the upper casing 1 .

[0042] The upper filte...

Abstract

The invention belongs to the technical field of diesel engine oil and gas separation devices, and in particular relates to a drum type high-efficiency diesel engine oil and gas separator, the separation design of the upper filter assembly and the lower filter assembly, without redesigning the mold, increasing the cost and manufacturing difficulty. The space layout of the diesel engine, adjust the position of the intake pipe and the exhaust pipe to meet the installation requirements; the first filter chamber, the second filter chamber and the one-way valve assembly can be used together to automatically adjust the airflow direction according to the amount of blow-by gas, ensuring that each The pressure loss and separation effect in the case of various blow-by gas volumes; the independent setting of the oil return hole and the oil return channel can avoid poor oil return, which will lead to the accumulation of oil and be carried out by the air flow from the air outlet, and the oil can be effectively collected and returned. The drum type high-efficiency diesel engine separator provided by the invention solves the problem that the outlet position of the oil and gas separator in the prior art is not adjustable, which limits the versatility of different models and the serial production of products, and cannot be automatically adjusted according to the amount of blow-by gas to ensure the separation effect. pressure loss problem.

Description

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