Description
Technical field
The present invention relates to it is a kind of it is portable alter oily detection device and its detection method, belong to the movement parts abrasion skill of air compressor machine
Art field.
Background technology
Air compressor machine alters the fault mode that oily failure is most commonly seen in commercial car industry.It is normal phenomenon that air compressor machine, which alters oil,
It is the unavoidable phenomenon caused by its own structure, normally alters oil and can be filtered and be discharged by subsequent drier
In air.But excessively high abnormal of air compressor machine alters oil and can cause drier that can not filter completely, not only the dry of drier is imitated
Fruit can gradually be lost, and extra machine oil can flow into gas receiver, hand valve, foot valve etc., solenoid valve etc. and subsequently use compressed air
Parts, it is serious to lead to various valve class product failures, eventually lead to vehicle brake system non-functional, influence driving peace
Entirely.
Air compressor machine is carried out at present alters the judgement of oily failure mainly using two ways：
Method 1：Air compressor machine is removed from engine, return air compressor machine manufacturer, which is on special test rack, to carry out altering oily survey
Examination.
Method 2：Publication No. is that the patent of invention of 105464957 A of CN discloses method：By air compressor machine on vehicle
Exhaust pipe disconnects, and is placing A4 cardboards apart from the positions exhaust outlet 10cm, is continuously connecing oil 1 minute, by the oil stain that gushes out come into
Row is judged.
Method 1 can accurately carry out altering oily judge, but need to remove air compressor machine from engine, and return to manufacture
It at quotient, needs to take a substantial amount of time and manpower and materials, simultaneously because test environment changes, therefore test result can not be complete
Reflect that alter oil meter of the air compressor machine on vehicle shows.Method 2 can not remove air compressor machine and directly be tested on vehicle, but by
What is gushed out in air compressor machine is oil water mixture, on connecing oiled cardboard is difficult that distinguish one from the other be oil be water, and sentencing for oil stain
Establish a capital be rely on direct feel, can not quantized values, be easy to cause judgement disagreement.Simultaneously because air compressor machine discharge is high pressure height
Wet body, therefore it is be easy to cause injury to personnel, safety is low.
Invention content
Problem that the purpose of the present invention is to overcome the above shortcomings provides a kind of not only safe but also convenient while also accurately portable
Formula alters oily detection device, for fast and accurately judging the air compressor machine on vehicle with the presence or absence of the abnormal situation and failure for altering oil.
The technical solution adopted by the present invention is：It is a kind of it is portable alters oily detection device, it includes gas path plate, collection tube, true

Sealing ring, hexagon socket head cap screw.Intake interface, pressure gauge, safety valve, regulating valve, acquisition interface are installed on gas path plate, air inlet
Interface is connected with air compressor machine gas outlet, and acquisition interface is connected with collection tube.Collecting tank is carried out with gas path plate by O-ring seal
Sealing, and be fastenedly connected by 6 uniformly distributed hexagon socket head cap screws, it is ensured that good seal.
Pressure gauge is used to monitor and show the pressure value of compressed air in collecting tank.Safety valve is by setting safe pressure
Value, it is ensured that the pressure value in collecting tank ensures equipment safety without departing from limit value.Regulating valve is used to adjust the pressure in collecting tank
Value, so that it is equal to Full Vehicle System pressure, while having both the effect of unloading valve, the compressed air after voltage stabilizing will be arranged from regulating valve to
Air.Acquisition interface is connected with collection tube, is the compressed air outlet of collection device.Collecting tank is the pressure vessel of customization,
The compressed air of certain pressure value can be stored.The compressed air that air compressor machine can be discharged for collection device is stablized in certain pressure
Force value, and temperature is reduced to≤30 °C.
Intake interface is connected by metal hose with air compressor machine gas outlet, is the compressed air inlet of collection device.It collects
Tank is pressure vessel, and it is 30bar that maximum, which bears pressure,.Detection pipe is mist of oil detection pipe, can individually be absorbed in compressed air
Mist of oil, and different colors is shown according to different oil concentrations, by color contrast standard color card, read concentration values.It adopts
Collector uses rubber material, is the path of compressed air circulation for connecting collection device and detection pipe.Vacuum hand pump need to be with inspection
Test tube matches, and the compressed air for extracting quantitative enters detection pipe.
Detection pipe is by reaction reagent pipe, and fracture area, filter layer, arrow mark, glass tube composition.Examination in reaction reagent pipe
The main component of agent is that sulfuric acid adds catalyst.Snap point is to be flexible coupling, and is point of penetration when detection pipe fractures.Filter layer is special
Weaving filter layer, adsorbable Oil in circulating gas mist.Arrow mark is the mark being printed on glass tube.Glass tube is outside transparent glass
Shell.Arrow mark must be directed toward vacuum hand pump when normal mounting.Surely there is oil-containing gases stream when empty-handed pump work, inside detection pipe
Logical, mist of oil will be attracted in filter layer；Surely empty-handed pump is stopped, then needs detection pipe to remove, firmly from the area that fractures
Detection pipe is fractureed, so that reaction reagent is flowed into filter layer, is fully reacted in filter layer, generates atrament, filtering
Color in layer can gradually from light to dark（White->Light brown or yellow->Black）, color variation range can also be gradually expanded.1
The color of detection pipe is compared with the subsidiary standard color card of detection pipe immediately after minute, you can read the dense of oil content
Angle value.
