Description
Technical field
The utility model is related to supply technology field, more particularly to a kind of braking air supply system.
Background technology
Domestic loading machine, various truck, car, use gas-liquid brake system at present.The system air compressor machine course of work
In, while compressed air is provided to gas receiver, can will let out generation in the steam in external environment condition, impurity and air compressor machine
Machine oil brings system into, causes concerned brake system failure, therefore braking air supply system preferably band oily-water seperating equipment.Band self-unloading
The air compressor machine of function, it is possible to decrease the power attenuation of engine, is greatly decreased the consumption of lubricating oil of air compressor machine, reduces noise etc..At present
It is divided into two kinds with self-unloading function, braking air supply system is free of according to air compressor machine function containing self-unloading.
The first is to brake air supply system for the air compressor machine without self-unloading function, and oil water separator is carried in system,
Compressed air from air compressor machine, oil water separator is entered by air inlet, oil, water and the impurity contained in air, through filter screen pair
Compressed air is filtered, and the compressed air for being filtered enters gas receiver through one-way cock, gas outlet.When gas receiver air pressure reaches
Highest limit value, the compressed air of gas outlet is acted on diaphragm by controlling gas circuit, is promoted and is moved in control piston assembly, and compression is empty
Gas enters into exhaust pition epicoele, promotes piston to open drain tap, the impurity such as the profit of internal separation is arranged by exhaust outlet
Go out.Now air inlet is communicated with exhaust outlet, and air compressor machine compressed air out enters air by the exhaust outlet of oil water separator.
When the air pressure of gas receiver drops to minimum limit value, when air pressure is not enough to overcome pressure spring pressure, control piston assembly is moved down,
Upper shifting closes exhaust valve port to drain tap under the action of the spring, and inlet, outlet is connected, and air compressor machine continues to be supplied to gas receiver.
Second is to brake air supply system for the air compressor machine containing self-unloading function, all without oil water separator.Gas receiver
Feedback port to air compressor machine is connected to pressure regulator valve.When brakes air pressure is to highest limit value, pressure regulator valve inlet, outlet is opened, storage
Air pressure in inflator reaches the elastic spring inside feedback port control aerostatic press, and the compressed air for exporting air compressor machine reaches it and enters
Gas port, realizes that air compressor machine dallies.When brakes air pressure drops to minimum value, pressure regulator valve inlet, outlet is closed, while outlet
Mouth is connected with exhaust outlet, and air compressor machine feedback port leads to air, and pressure spring off-load, air compressor machine recovers supply.
Increase oil water separator, the control gas circuit and profit of pressure regulator valve in the air supply system of the air compressor machine of function containing self-unloading
The control gas circuit of separator is communicated.If the Opening pressure of pressure regulator valve is higher than the Opening pressure of oil water separator, water-oil separating
Device is opened and pressure regulator valve will not be opened, and compressed air cannot reach feedback port, and air compressor machine loses feedback function.Now system passes through
Oil water separator pressure regulation, with above-mentioned the first system.If the Opening pressure of pressure regulator valve is less than the Opening pressure of oil water separator,
Then pressure regulator valve is opened and oil water separator exhaust outlet cannot be opened, air compressor machine possesses feedback function, but now oil water separator
Exhaust outlet is not turned on, and its internal separate impurity cannot be discharged, and will bring braking system faults.Therefore for function containing self-unloading
The air supply system of air compressor machine, cannot be provided simultaneously with two kinds of functions of water-oil separating and air compressor machine self-unloading at present.
Utility model content

Into the control piston assembly outside is arranged with pressure spring, and pressure spring upper end is connected with spring base, the spring base peace
On oil water separator inwall, the exhaust pition side is communicated with air inlet, and air inlet extends outside oil water separator
Side, another upper lateral part of exhaust pition is communicated with control gas circuit, and control gas circuit is communicated with one-way cock, the one-way cock
Side is communicated with the air inlet on oil water separator；
The gas outlet of the oil water separator is communicated in the import of air compressor machine, and the outlet of air compressor machine is connected by pipeline
In Ls feedback ports, the gas outlet of the oil water separator is connected to gas receiver by pipeline.
Preferably, it is provided with diaphragm between the exhaust pition and control piston assembly.
Preferably, the import of the air compressor machine is provided with joint with exit, and joint is connected to pipeline for connecting
Oil water separator.
The utility model proposes a kind of braking air supply system, beneficial effect is：The braking air supply system is realized
In the air supply system of the air compressor machine of function containing self-unloading, Ls feedback ports are increased by oil water separator, profit point is increased to system
From device, the cleaning inside air supply system is ensure that while energy-conservation, be provided simultaneously with water-oil separating and air compressor machine self-unloading two
Function is planted, while water-oil separating is realized, the self-unloading of air compressor machine is realized, the power attenuation of engine is reduced, significantly subtracted
The consumption of lubricating oil of few air compressor machine, reduces noise.
