Drier receiver is the core component in the automotive air-conditioning system, plays effect dry and storage liquid in air-conditioning system, also has simultaneously and filters and the booster action that is connected air-conditioning duct.For 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 to weld the process such as (soldering, argon arc welding), machining in process, so the possibility of impurity (such as iron filings, oxide skin etc.) to occur very large in drier receiver inside.Also there is not at present a kind of effective equipment to detect contained impurity 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 as follows: lower 18 ℃～28 ℃ of room temperature, weigh in advance through 90 ℃ ± 5 ℃, the filter paper that is no less than the 30min drying, the isooctane solvent that is about drier receiver volume 30% is poured 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 detecting, reality can't operate, reason is as follows: the structural representation of drier receiver is referring to Fig. 2: because due to the drier receiver structure, can't into the isooctane solvent of drier receiver will be poured, after shaking for 4～5 times, all pour out, more can't checked for impurities content.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of impurity detection device for receiver driers that can effectively detect impurity content in the automotive air-conditioning system drier receiver, to guarantee the cleanliness requirement of drier receiver.
The technical scheme that solves the problems of the technologies described above is: a kind of impurity detection device for receiver driers, this device comprises gas making device, drier receiver, impurity collector and weighing device, described drier receiver is airtight container, and drier receiver, be provided with filtering layer in the impurity collector, the output terminal of described gas making device is communicated with the top of drier receiver inner filtration layer by pipeline A, the below of drier receiver inner filtration layer is communicated with the below of impurity collector inner filtration layer by pipeline B, the top of impurity collector inner filtration layer is in communication with the outside by 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.
Again further technical scheme of the present invention is: automatic pressure control also is installed between the input end of described dry gas tank and the air valve.
Another technical scheme of the present invention is: described weighing device is electronic scales.
Because adopt technique scheme, the present invention's impurity detection device for receiver driers compared with prior art has following beneficial effect:
1, because the present invention's impurity detection device for receiver driers 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 by gas making device, make the impurity of drier receiver inside along with compression drying gas is discharged from drier receiver, enter 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, the impurity for the treatment of drier receiver all is collected in the impurity collector, can weigh up impurity content by 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 gauge tap of each parts, can finish testing, need not manually drier receiver to be 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 the fault such as air-conditioning system obstruction, prolonged the serviceable life of automotive air-conditioning system.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the present invention's impurity detection device for receiver driers is further described.
