Clean air through Vehicular air compression set compression after, be stored in vehicle air accumulator.Unloading valve senses gas in air accumulator
After body air pressure reaches setup pressure value, unloading valve can cut off the connection of Vehicular air compression set and air accumulator, simultaneously turn on big
Gas, because Vehicular air compression set continues to work, bulk gas will be arranged by unloading port to atmosphere.But at present
Most of Vehicular air compression set is mostly liquid oil lubrication, and the high temperature that when compressed air generates causes piston position lubricating oil
The phenomenon that being gasified and entering in gas exhaust piping with compressed gas, cause air-following oil drain.It will lead to oil, water contained in gas
Equal impurity finally deposit and adsorb dust in the position of sewage draining exit, ultimately form the greasy dirt at sewage draining exit position, influence the beauty of vehicle
It sees.Bulk gas is discharged from sewage draining exit for a long time, if the greasy dirt of sewage draining exit reaches a certain level and cannot timely cleaning maintenance
If, it can further block silencer.Silencer after obstruction increases the off-load resistance of air compression plant, air compression dress
The service life set will be affected, while also increase the oil consumption of engine.
Summary of the invention
The utility model provides a kind of Vehicular air compression set with self-circulation system, can inhibit Vehicular air pressure
The phenomenon that compression apparatus air-following oil drain.
The following are the technical solution of the utility model includes:
A kind of Vehicular air compression set with self-circulation system, including it is air cleaner, air compressor for vehicle, dry
Dry device, air accumulator and exhaust circulating system, the drier are equipped with sewage draining exit, the air cleaner, the Vehicular air
Compressor and the air accumulator are sequentially communicated by connecting tube, the input terminal and output end of the exhaust circulating system respectively with institute
The outlet side for stating air compressor for vehicle is connected to inlet end.
The above-mentioned Vehicular air compression set with self-circulation system, the exhaust circulating system include exhaust cycle pipe and
Three interfaces of two-bit triplet reversal valve, the two-bit triplet reversal valve distinguish the input terminal of the exhaust cycle pipe, the vehicle
It is connected to the output end of air compressor with the input terminal of the drier；The output end of the exhaust cycle pipe with it is described automobile-used
The input terminal of air compressor is connected to.
The above-mentioned Vehicular air compression set with self-circulation system, is additionally provided with reversing valve signal driving tube, and described two
Three-way diverter valve be solenoid valve or Pneumatic valve, the both ends of the reversing valve signal driving tube respectively with two-bit triplet reversal valve and do
Dry device connection.
The above-mentioned Vehicular air compression set with self-circulation system is connected with silencing means on sewage draining exit.
Compared with prior art, exhaust when gas atmosphere reaches setup pressure value in air accumulator, in the utility model
Gas in drier can be introduced to the air inlet pipeline of air compressor for vehicle by the circulatory system, to reduce showing for air-following oil drain
As decreasing the exhaust of oil of drier sewage draining exit, being conducive to environmental protection；Extend the service life of gas exhaust piping component；
Reduce the off-load resistance of air compressor for vehicle, reduces engine power consumption；The aesthetics of vehicle is improved simultaneously.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Label in attached drawing indicates: 1. air cleaners；2. air compressor for vehicle；3. drier；4. air accumulator；5.
Exhaust cycle pipe；6. reversing valve signal driving tube；7. two-bit triplet reversal valve；9. sewage draining exit；91. silencing means.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is for illustrating the utility model.
As shown in Fig. 1, the utility model includes air cleaner 1, air compressor for vehicle 2, drier 3, air accumulator 4
And exhaust circulating system, the drier are equipped with sewage draining exit 9, are connected with silencing means 91 on sewage draining exit 9.The air-filtering
Device 1, the air compressor for vehicle 2 and the air accumulator 4 are sequentially communicated by connecting tube, the input of the exhaust circulating system
End and output end are connected to the outlet side of the air compressor for vehicle 2 and inlet end respectively.
The exhaust circulating system includes exhaust cycle pipe 5 and two-bit triplet reversal valve, the two-bit triplet reversal valve 7
Three interfaces distinguish the output end and the drier 3 of the input terminal of the exhaust cycle pipe 5, the air compressor for vehicle 2
Input terminal connection；The output end of the exhaust cycle pipe 5 is connected to the input terminal of the air compressor for vehicle.
In order to realize automatic control off-load, it is additionally provided with reversing valve signal driving tube 6, the two-bit triplet reversal valve is electromagnetism
The both ends of valve or Pneumatic valve, the reversing valve signal driving tube 6 are connected to two-bit triplet reversal valve and drier respectively.
In practical work process, two-bit triplet reversal valve makes between air compressor for vehicle and drier for access, row
