The drier receiver impurity detection device
Technical field
The present invention relates to a kind of pick-up unit of automotive air-conditioning system drier receiver, particularly a kind of drier receiver impurity detection device.
Background technology
Drier receiver is the core component in the automotive air-conditioning system, in air-conditioning system, plays effect dry and storage liquid, also has simultaneously and filters and the booster action that is connected air-conditioning duct.As far as automotive air-conditioning system, its cleanliness to the air conditioning for automobiles parts require very high, if the impurity content that exists in the air-conditioning system is too high, will cause the air-conditioning system plugging fault; For drier receiver, drier receiver has two kinds in iron bottle and aluminum bottle; Two kinds of drier receivers all need weld process such as (soldering, argon arc welding), machining in process, so the possibility of impurity (like iron filings, oxide skin etc.) to occur very big in drier receiver inside.At present also there is not a kind of effective equipment to detect impurity contained in the drier receiver.In the automobile industry standard (QC/T662-200) of air conditioning for automobiles (HFC-134a) with drier receiver a kind of cleanliness test method has been proposed; Method is following: following 18 ℃~28 ℃ of room temperature; Weigh in advance through 90 ℃ ± 5 ℃, be no less than the dry filter paper of 30min, pour the isooctane solvent that is about drier receiver volume 30% into drier receiver; Pour out through filter paper filtering after shaking 4~5 times, filter paper is weighed after the same temperature, time drying.There is certain defective in this test method; In actual detected, can't operate; Reason is following: the structural representation of drier receiver is referring to Fig. 2: because due to the drier receiver structure; Can't be with the isooctane solvent of pouring drier receiver into, after shaking for 4~5 times, all pour out, more can't checked for impurities content.
Summary of the invention
The technical matters that the present invention will solve is: a kind of drier receiver impurity detection device that can effectively detect impurity content in the automotive air-conditioning system drier receiver is provided, to guarantee the cleanliness requirement of drier receiver.
The technical scheme that solves the problems of the technologies described above is: a kind of drier receiver impurity detection device; This device comprises gas making device, drier receiver, impurity collector and weighing device; Described drier receiver is airtight container; And be provided with filtering layer in drier receiver, the impurity collector, the output terminal of said gas making device is communicated with the top of drier receiver inner filtration layer through pipeline A, and the below of drier receiver inner filtration layer is communicated with the below of impurity collector inner filtration layer through pipeline B; The top of impurity collector inner filtration layer is in communication with the outside through pipeline C, and described impurity collector is positioned on the weighing device.
Further technical scheme of the present invention is: described gas making device comprises air strainer, air compressor, dry gas tank; Described air strainer input end is communicated with atmosphere; The air strainer output terminal is connected with the input end of air compressor; The output terminal of air compressor is connected with dry gas tank input end; The output terminal of dry gas tank is connected with pipeline A, on this pipeline A air valve is installed, and is communicated with the top of drier receiver inner filtration layer.
Further again technical scheme of the present invention is: automatic pressure control also is installed between the input end of said dry gas tank and the air valve.
Another technical scheme of the present invention is: described weighing device is an electronic scales.
Because adopt technique scheme, the present invention's drier receiver impurity detection device compared with prior art has following beneficial effect:
1, because the present invention's drier receiver impurity detection device comprises gas making device, drier receiver, impurity collector and weighing device; Can in drier receiver, be blown into a large amount of clean compression drying gases through gas making device; Make the inner impurity of drier receiver along with compression drying gas is discharged from drier receiver, get into afterwards in the impurity collector, owing to be provided with filtering layer in the impurity collector; Thereby impurity is blocked in the impurity collector; Compression drying gas then can be discharged from pipeline C, treats that the impurity of drier receiver all is collected in the impurity collector, can weigh up impurity content through weighing device.In addition, be clean compression drying gas owing to what in drier receiver, be blown into, can not bring any impurity to drier receiver again, thereby the present invention can accurate and effectively detect the impurity content in the drier receiver.
2, easy and simple to handle:
The present invention only need start the CS of each parts, can accomplish testing, need not manual work drier receiver is shaken repeatedly, and its operation is very easy.
3, can guarantee the high cleanliness requirement of air conditioning for automobiles parts:
Because the present invention can accurate and effectively detect the impurity content in the drier receiver, thereby it can guarantee the high cleanliness requirement of air conditioning for automobiles parts, thereby avoid fault such as air-conditioning system obstruction, prolonged the serviceable life of automotive air-conditioning system.
Below, in conjunction with accompanying drawing and embodiment the technical characterictic of the present invention's drier receiver impurity detection device is further described.
