Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to an oil-gas separator shell capable of effectively reducing noise. Background Art

[0002] The oil-gas separator for automobiles is installed next to the engine crankcase ventilation valve. When the engine is working, the cylinder's bubbling and oil vapor will generate pressure, which will cause damage to the engine. Therefore, it is necessary to use the crankcase ventilation valve to create a vacuum. Since the gas extracted from the crankcase ventilation valve contains a large amount of oil vapor, an oil-gas separator is needed to separate the oil vapor into oil and steam.

[0003] At present, when the oil-gas separator is working, the noise caused by vibration is relatively large, and it will deform under long-term high temperature, which will cause oil leakage in the product. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0005] Provides an oil-gas separator housing with effective noise reduction, strengthens the product geometry, enhances product rigidity, reduces product deformation under long-term high temperature, reduces product oil leakage, improves reliability and service life, and reduces noise 。

[0006] To achieve the above purpose, the utility model provides an oil-gas separator housing with effective noise reduction, including a shell, a side of the shell is provided with an intake manifold connecting pipe, and the bottom of the shell is provided with a crankcase connecting pipe, characterized in that: a plurality of ribs are provided on the inner wall of the shell.

[0007] By adopting the above technical solution and adding several ribs, the product's geometric structure is strengthened, the product's rigidity is enhanced, the product's deformation under long-term high temperature is reduced, the product's oil leakage is reduced, and the reliability and service life are improved. After the product structure is strengthened, the vibration amplitude of the object is reduced, the sound source increases resistance, the ribs absorb part of the sound waves, and the frequency is changed, which can avoid resonance with the crankcase, thereby achieving the effect of reducing noise.

[0008] The above technical solution is further configured as follows: an end of the shell away from the crankcase connecting pipe is provided with an end cover connected to the shell.

[0009] By adopting the above technical solution, the connection between the end cover and the shell can further reduce noise.

[0010] The above technical solution is further configured as follows: a plurality of annular grooves are provided on the outer wall of the crankcase connecting pipe, and a rubber ring matching the annular groove is provided on the annular groove.

[0011] The above technical solution is further configured as follows: the number of the ribs is 4.

[0012] By adopting the above technical solution and adding four ribs, the geometric structure of the product is strengthened, the rigidity of the product is enhanced, the deformation of the product under long-term high temperature is reduced, the oil leakage of the product is reduced, and the reliability and service life are improved. After the product structure is enhanced, the vibration amplitude of the object is reduced, the sound source increases the resistance, and the four ribs absorb part of the sound waves, the frequency is changed, and resonance with the crankcase can be avoided, thereby achieving the effect of reducing noise.

[0013] The beneficial effects achieved by the utility model are as follows: after adding a number of ribs, the geometric structure of the product is strengthened, the rigidity of the product is enhanced, deformation of the product under long-term high temperature is reduced, oil leakage of the product is reduced, and reliability and service life are improved. After the product structure is enhanced, the vibration amplitude of the object is reduced, the resistance of the sound source is increased, the ribs absorb part of the sound waves, the frequency is changed, and resonance with the crankcase can be avoided, thereby achieving the effect of reducing noise.

[0017] An oil-gas separator housing with effective noise reduction shown in this embodiment includes a shell 1, an intake manifold connecting pipe 3 is provided on the side of the shell 1, a crankcase connecting pipe 5 is provided on the bottom of the shell 1, a plurality of annular grooves 6 are provided on the outer wall of the crankcase connecting pipe 5, a rubber ring 7 matching the annular groove 6 is provided on the annular groove 6, the crankcase connecting pipe 5 is connected to the crankcase, a separator device is provided in the shell, a plurality of ribs 4 are provided on the inner wall of the shell 1, the inner cavity of the oil-gas separator shell increases the damping of oil vapor convection, so that the rising oil and gas in the crankcase increases the damping distance during the wandering process, and obtains lighter oil and gas sedimentation and is converted into oil droplets, which then flow back to the crankcase along the inner wall of the shell 1 and the crankcase connecting pipe 5, thereby reducing the loss of engine oil.

[0018] An end of the shell 1 away from the crankcase connecting pipe 5 is provided with an end cover 2 connected to the shell 1 . The connection between the end cover 2 and the shell 1 can further reduce noise.

[0019] The number of the ribs 4 is 4. After adding the ribs 4, the geometric structure of the product is strengthened, the rigidity of the product is enhanced, the deformation of the product under long-term high temperature is reduced, the oil leakage of the product is reduced, and the reliability and service life are improved. After the product structure is enhanced, the vibration amplitude of the object is reduced, the sound source increases the resistance, the ribs 4 absorb part of the sound waves, the frequency is changed, and resonance with the crankcase can be avoided, thereby achieving the effect of reducing noise.

[0020] The crankcase connecting pipe 5 is connected to the crankcase through the ventilation valve. The oil and gas generated in the engine combustion chamber enter the housing 1 through the crankcase and the ventilation valve, and the oil and gas swirl around the inner wall above the housing. The 4 ribs provided can increase the damping distance of the rising oil and gas in the crankcase during the swirling above the housing 1, making it easier for the oil and gas to condense and convert into oil droplets, and then flow back to the crankcase along the inner wall of the housing 1 and the crankcase connecting pipe 5, thereby reducing the loss of engine oil. The gas separated from the oil and gas enters the intake manifold through the intake manifold connecting pipe 3, and re-enters the combustion chamber from the intake valve for secondary combustion.
