when the lubricating oil level in the oil-gas separator is low, the lower end part of the supporting and positioning rod is inserted into the lower groove, the supporting and positioning rod is in clearance fit with the lower groove, and the boss is inserted into the upper groove;
when the lubricating oil level in the oil-gas separator is high, the groove protrudes from the lower groove.
The invention further improves that:
preferably, the supporting and positioning rod comprises a supporting rod and a liquid level rod which are coaxially and integrally connected, and the boss is arranged between the supporting rod and the liquid level rod;

Compared with the prior art, the invention has the following beneficial effects:
The invention discloses an oil-gas separator based on an oil-disturbance noise suppression structure, wherein a through hole and a groove are arranged at the lower part of a supporting rod, deposited lubricating oil can flow into a lubricating oil hole from a through hole mixed groove, and the supporting and positioning rod can float when the lubricating oil quantity is large through the matching of the lower end of the supporting and positioning rod and a lower groove and the matching of a boss and an upper groove. After the separator is used, the oil quantity in the cylinder can be maintained at a proper level. The upper surface and the lower surface of the separator are both provided with porous materials, when the separator is used, the optimal state is that the porous materials on the lower surface of the floating plate are always soaked in the lubricating oil liquid level at the bottom of the oil-gas separator, and the porous materials on the upper surface of the floating plate are not soaked in the lubricating oil liquid, so that the oil disturbing noise generated by fluctuation of the lubricating oil liquid level can be restrained, and the noise of the oil-gas separator is reduced.
Further analysis, the liquid level fluctuation generates bubbles on one hand, the bubbles break to generate noise, and on the other hand, the liquid level fluctuation impacts the structural member to generate vibration radiation noise, and the vibration radiation noise is induced by the liquid level fluctuation and is called oil disturbing noise. The porous material at the lower part just contacts the liquid surface or is partially immersed in the liquid surface, on the one hand, bubbles are not easy to generate due to the existence of the porous material, and even a small amount of bubbles are generated, the bubbles are easily absorbed by the porous material, on the other hand, when the porous material is immersed in the liquid surface of the lubricating oil, the fluctuation of the liquid surface can be reduced. In contrast, if the level of the lubricating oil exceeds the upper porous material, the phenomenon of air bubbles and liquid level fluctuation will continue to occur, and the oil noise suppressing structure at this time is immersed in the lubricating oil as if it were a solid structure, and only the liquid level is increased, but a certain effect is lost in reducing the oil noise.
Further, the supporting and positioning rod is divided into a supporting rod at the upper part and a liquid level rod at the lower part, the supporting rod is used for being connected with the floating plate, and the lower end of the liquid level rod is used for being matched with the groove to realize flow control.
Further, the diameter of the boss is larger than that of the liquid level rod, so that when the quantity of lubricating oil is small, the lower surface of the boss is attached to the upper surface of the lower groove, and a part of oil is prevented from entering the lower groove, so that lubricating oil can only flow into the lubricating oil hole through the horizontal through hole in the boss.
Further, the annular cavity of the floating plate is a cavity, so that when the amount of lubricating oil is small, the volume of the annular cavity of the floating plate immersed in lubricating oil is reduced, buoyancy is reduced, the oil disturbing noise structure is restrained from moving downwards, the lower end of the liquid level rod is inserted into the lower groove, and lubricating oil can only be discharged into the oil drain hole through the through hole in the boss. Because the effective through flow area of the through hole on the boss is smaller, the lubricating oil at the bottom of the oil content barrel is gradually increased, the liquid level is increased, the volume of the annular cavity of the floating plate immersed in the lubricating oil is increased, the buoyancy is increased, the oil disturbing noise structure is restrained from moving upwards, the groove at the lower part of the supporting rod is protruded out of the lower groove, the lubricating oil can be discharged from the through hole on the boss and the groove at the lower part of the supporting rod at the same time, the oil discharge sectional area is increased, the liquid level of the lubricating oil is reduced, and the dynamic balance of the liquid level of the lubricating oil is realized.
Further, the annular cavity is provided with a lubricating oil channel, so that lubricating oil can flow into the lower part above the floating plate.
Further, porous materials are arranged on the upper surface and the lower surface of the annular cavity and are always soaked in the lubricating oil liquid level at the bottom of the oil-gas separator, so that bubbles in the lubricating oil can be absorbed.
Further, the limit portion of annular cavity and porous material's limit portion are wrapped up by the cutting ferrule jointly, on the one hand can make porous material be difficult to remove on annular cavity, on the other hand cutting ferrule can seal the gap between annular cavity and the barrel.
Further, the horizontal through holes are arranged around the boss in an equal mode, so that the number and the positions of the through holes can meet the requirement of lubricating oil outflow.
Further, the effective flow area of the horizontal through hole and the groove is limited, and outflow of liquid is ensured.

Furthermore, the height of the liquid level is adjusted through the arrangement of the through flow area of the horizontal through hole and the effective through flow area of the groove, so that the liquid level can reach the optimal height, for example, the porous material on the lower surface of the floating plate is always soaked in the lubricating oil liquid level at the bottom of the oil-gas separator, and the porous material on the upper surface of the floating plate is not soaked in the lubricating oil.
Referring to fig. 5, the base 22 is provided with an upper groove 2201, a lower groove 2202, a base drain hole 2203 and a screw hole 2204.

the oil-gas mixture enters a cavity mainly composed of the cylinder 21, the base 22 and the upper cover 23 from the flange 26 and the air inlet pipe 27 for oil-gas separation, the separated gas is discharged from the upper cover 23 into the gas path system, and the separated lubricating oil is firstly stored at the bottom of the cylinder 21 through the lubricating oil channel 1203 and then discharged into the oil path system through the oil discharge pipe 29.
When the liquid level of the lubricating oil rises, the volume of the oil disturbing noise structure 1 immersed in the lubricating oil increases, the buoyancy received increases, the oil disturbing noise structure 1 is restrained from moving upwards, the effective flow area of the lubricating oil passing through the horizontal through hole 1104 and/or the groove 1105 increases, the oil discharge amount increases, and the liquid level of the lubricating oil decreases. When the lubricating oil level falls, the volume of the oil noise suppressing structure 1 immersed in the lubricating oil level is reduced, the buoyancy received is reduced, the oil noise suppressing structure 1 is suppressed from moving downward, the liquid level rod 1103 falls into the lower groove 2202, and simultaneously the boss 1102 falls into the upper groove 2201, at this time, the effective flow area of the lubricating oil through the horizontal through hole 1104 and/or the groove 1105 is reduced, the oil discharge amount is slowed down, and the lubricating oil level rises. By designing the relative positions of the horizontal through hole 1104 and the bevel 1105 in the vertical direction of the supporting and positioning rod 11, the liquid level height of the lubricating oil is controlled, the dynamic balance of the liquid level of the lubricating oil is realized, and the oil disturbing noise induced by fluctuation of the liquid level of the lubricating oil is restrained.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
