Abstract
The invention discloses an oil-gas separation device for an engine. The oil-gas separation device belongs to parts in the technical field of engines. The oil-gas separation device mainly comprises an oil-gas separation chamber, a gas inlet pipe and a gas outlet pipe are arranged above the oil-gas separation chamber, an oil return pipe is arranged at the bottom of the oil-gas separation chamber, and the gas inlet pipe penetrates through the top of the oil-gas separation chamber and extends into the inner bottom of the oil-gas separation chamber; an oil-gas separator is arranged at an outlet of the gas inlet pipe inside the oil-gas separation chamber; a fixing device can be arranged on one side of the oil-gas separation chamber. The oil-gas separation device is simple in structure, low in cost and convenient to use; the oil-gas separation chamber is arranged outside the engine, so the oil-gas separation device inside the engine is simplified; in addition, engine oil can be effectively prevented from leaking out of the engine on the basis that the original lubricating effect of the engine is not affected. The oil-gas separation device is mainly applied to the engine.
Description
Technical field
The invention belongs to a kind of parts in technical field of engines, specifically, relate in particular to a kind of engine oil-gas separating device.
Background technique
Engine fuel in the course of the work, due to the operation up and down of piston and the existence of piston ring gap, cause the pressure leakages of firing chamber to engine interior, cause motor internal pressure to change at any time, therefore engine interior need to have the connectivity structure of connecting with ambient atmosphere, and the pressure of balanced engine inside changes.Due to engine interior, there is in addition the machine oil of lubricated use, machine oil can be along with the variation of engine interior pressure, and the connectivity structure of connecting by engine interior and atmosphere is leaked to external engine, causes the disappearance of machine oil, cause engine failure, and cause environmental pollution.
Traditional motor, connectivity structure is placed on middle part or the top of motor, labyrinth structure or gas and oil separating plant are set in connectivity structure, at machine oil, along with changing, motor internal pressure enters after connectivity structure, by labyrinth structure or gas and oil separating plant, the mobile of machine oil hindered, make machine oil under the effect of gravity, be back to engine interior.Because engine interior pressure changes greatly, labyrinth structure or gas and oil separating plant cannot will filter out along with pressure changes mobile machine oil in motor completely, and part machine oil still can be along with air-flow is leaked to external engine.
Summary of the invention
For the connectivity structure that solves conventional engines in prior art cannot will filter out along with pressure changes mobile machine oil in motor completely, cause part machine oil still can be leaked to along with air-flow the defect of external engine, the invention provides a kind of engine oil-gas separating device.
The present invention is achieved by the following technical solutions:
A kind of engine oil-gas separating device, comprises Oil-gas Separation chamber, and top, Oil-gas Separation chamber is provided with suction tude and steam outlet pipe, and bottom, Oil-gas Separation chamber is provided with return tube, and suction tude is passed top, Oil-gas Separation chamber and extended to the inner bottom part of Oil-gas Separation chamber.
The high-pressure oil gas with oil droplet of discharging through motor connectivity structure, by suction tude, enter into bottom, Oil-gas Separation chamber, due to the existence of steam outlet pipe, Oil-gas Separation chamber internal pressure reduces, oil droplet in high-pressure oil gas is due to the effect of the gravity of pressure, can accumulate in the bottom of Oil-gas Separation chamber, then via return tube, flow back in the engine oil chamber of motor.
The outlet port of the indoor suction tude of Oil-gas Separation is provided with deaerator.
The oil gas that suction tude is discharged further filters through deaerator, high-pressure oil gas is filtered more thorough.
One side of Oil-gas Separation chamber can be provided with fixing device.
The present invention can be arranged on motor by fixing device.
Oil-gas Separation chamber can adopt cylindrical structure.
Oil-gas Separation chamber also can adopt special pipe structure.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is simple in structure, with low cost, easy to use, Oil-gas Separation chamber is arranged on to external engine, simplify the gas and oil separating plant of engine interior, and can not affect on the basis of the original lubrication effect of motor, effectively avoided oil leakage to arrive external engine.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment one: a kind of engine oil-gas separating device, comprise Oil- gas Separation chamber 2,2 tops, Oil-gas Separation chamber are provided with suction tude 3 and steam outlet pipe 1, and 2 bottoms, Oil-gas Separation chamber are provided with return tube 6, and suction tude 3 is passed 2 tops, Oil-gas Separation chamber and extended to the inner bottom part of Oil-gas Separation chamber 2; The outlet port of the interior suction tude 3 in Oil-gas Separation chamber 2 is provided with deaerator 5; One side of Oil-gas Separation chamber 2 is provided with fixing device 4; Oil-gas Separation chamber 2 adopts cylindrical structure.
Embodiment two: Oil-gas Separation chamber 2 adopts special pipe structure; Other is identical with embodiment one.
The present invention is when making, and Oil-gas Separation chamber 2 can make as a wholely with the parts of motor, also can by bonding, fastening or bolt, be fixedly connected with motor, during use, return tube 3 communicates with the engine oil chamber of motor, suction tude 3 is connected with the connectivity structure of motor, the high-pressure oil gas that engine interior running produces, by suction tude 3, enter Oil-gas Separation chamber 2, due to the steam outlet pipe 1 on Oil-gas Separation chamber 2, pressure in Oil-gas Separation chamber 2 is less, high-pressure oil gas enters behind Oil-gas Separation chamber 2, because pressure reduces and the effect of gravity, oil droplet in high-pressure oil gas can accumulate in the bottom of Oil-gas Separation chamber 2, high-pressure oil gas is again after deaerator 5 filters, through steam outlet pipe 1, discharge, oil droplet is by the engine oil chamber of return tube 6 inflow engines.
