Description
Technical field
The present invention relates to engine components, be specifically related to a kind of gas and oil separating plant of engine crankshaft ventilation system.
Background technique
In traditional engine crankshaft ventilation system, the Oil-gas Separation labyrinth is designed to baffle-type or rotary type structure.As CN 20164956 U disclosed " labyrinth oil gas separator of crankcase ventilation system ", this device is provided with some in valve chamber cover and valve chamber cover is the baffle plate of one, the upper-end surface of baffle plate flushes with the Oil-gas Separation channel seal face of valve chamber cover, baffle plate one side is provided with opening, intersect wrong about the aperture position on the adjacent screen, make and flow through, to improve the effect of Oil-gas Separation through fluctuation ground about the oil gas of passage.But, find that in use the Oil-gas Separation labyrinth of baffle-type is lower to the separation effect of mixed oil and gas.And the suction port place that separates the labyrinth generally is designed to through hole, and mixed oil and gas directly enters and separates the labyrinth, causes the mixed oil and gas oil content higher, is unfavorable for the separation that oil is gentle.Therefore, exist improved needs.
Summary of the invention
The gas and oil separating plant that the purpose of this invention is to provide a kind of engine crankshaft ventilation system, it can reduce the oil droplet content that enters in the mixed oil and gas that separates in the labyrinth, improves Oil-gas Separation efficient.
The gas and oil separating plant of a kind of engine crankshaft ventilation system of the present invention is characterized in that: the inlet or the skimming baffle place of the mazy type oil gas split tunnel on the cylinder cover are provided with a macromolecule separating plate.
The gas and oil separating plant of described a kind of engine crankshaft ventilation system, the section of the mazy type oil gas split tunnel on its described cylinder cover is drawn together and is " doorframe " shape, on the end face of mazy type oil gas split tunnel is provided with the projection of a horizontal groove, two side, be respectively equipped with a vertical groove, below be connected with a ventilation cover plate; Horizontal groove and ventilation cover plate corresponding contact are passed by the bottom of described macromolecule separating plate, the dual-side of macromolecule separating plate respectively with two vertical groove fit; One plate that changes the outfit is connected with horizontal groove.
The gas and oil separating plant of described a kind of engine crankshaft ventilation system is provided with a long-pending oil groove at the middle part of described ventilation cover plate, is provided with a spill port at least in the bottom of this long-pending oil groove.
The gas and oil separating plant of described a kind of engine crankshaft ventilation system is provided with a bolt respectively via hole is installed, and is connected by the horizontal groove of the mazy type oil gas split tunnel on two bolts and the cylinder cover at the two end part of the described plate that changes the outfit.
The gas and oil separating plant of described a kind of engine crankshaft ventilation system, its described macromolecule separating plate is a disk construction, and cellular hole is arranged on it.
When mixed oil and gas passed through the macromolecule separating plate, the oil droplet that diameter is bigger was attracted in the macromolecule separating plate, and in hole flow to the long-pending oil groove that designs on the ventilation cover plate, machine oil can flow back in the camshaft grease chamber by spill port.Hole quantity in the pore size of macromolecule separating plate and the unit area directly has influence on separation effect, so can use unlike material (as: plastic polymer in nonwovens, crack with holes) as required when design.
During use, the present invention is arranged on the inlet that separates the labyrinth, perhaps be arranged on the skimming baffle place that separates the labyrinth, when mixed oil and gas passes through the macromolecule parting material, owing on the material the cellular hole that is evenly distributed is arranged, gas can pass through smoothly, but hole can adsorb the oil droplet in the mixed gas, isolates the bigger oil droplet of diameter in the oil gas.Can flow in the oil groove that separates the cover plate design by the hole in material after oil droplet is isolated, return the camshaft grease chamber.
The interference fit of macromolecule separating plate by the left and right sides is installed in the vertical groove on the cylinder cover, and the bottom is directly installed in the long-pending oil groove of ventilation cover plate, and top compresses by the plate that changes the outfit.Because after the long-time use of macromolecule separating plate, stopping up may appear in hole, so, need change the macromolecule separating plate.Only need pull down the plate that changes the outfit when changing the macromolecule separating plate and get final product, all very simple and easy during installation and removal.Plate need carry out gluing sealing because change the outfit, so the plate design length that changes the outfit is longer slightly than horizontal groove, like this, can pull down by the extension plate that will change the outfit easily when dismounting.
Beneficial effect of the present invention: effectively raise oil gas separation, reduced the consumption of machine oil, prolonged the service time of machine oil; Guarantee the performance of ventilation system, and prolonged the life cycle of system.
