Description
Technical field
The present invention relates to a kind of detection methods influencing Packaging Case for Satellite air-tightness defect.
Background technology
Protection when Packaging Case for Satellite is for satellite transfer and storage.Packaging Case for Satellite needs to be filled with indifferent gas when in use
Body needs to ensure to seal inside packing case to ensure the pressure of inert gas inside packing case.The structure of Packaging Case for Satellite is as schemed
(1) shown in.
Packaging Case for Satellite generally uses the structure of case lid and babinet, is locked using hasp and sealing ring between case lid and babinet
And sealing.Case lid is similar with the structure of babinet, and intermediate course is welded into basic framework using aluminium alloy or bar section of stainless steel, and
With filled and process, interior outside then uses stainless steel plate or aluminium alloy plate as covering.Packing case generally relies on inner metal plate company
Continuous welding ensures inner sealing.
The manufacturing process of Packaging Case for Satellite is generally：Welding equipment general frame, side skin in welding equipment, heat treatment, FCL machine add
Work, laminated foam filling, outer skin welding equipment, case lid are machined with babinet counterface, whole assembly and spray painting etc..
After the completion of FCL is assembled, FCL air seal test generally is carried out using inflation/deflation interface for Packaging Case for Satellite.This side
Method can directly detect it is various fill the connectors Air Leakage Defect such as exhaust, cable plug position, but when inside panel raw material and commissure are deposited
It, can not be directly from packet in the interlayer and sectional materials cage of the gas direct emission of leakage between interior exterior skin in defect gas leakage
Vanning external detection determines specific defective locations.It generally requires after opening packing case, using surface inspection method to babinet
It is detected, takes a substantial amount of time with the entire defect in inner surface of case lid, for part packing case, arranged by multiple detection
It looks into, all defect in inner surface cannot still be excluded.
Invention content
To solve deficiency in the prior art, the present invention provides a kind of airtight defect inspection method of Packaging Case for Satellite,
Can accurately, completely find out influences the defective locations of Packaging Case for Satellite air-tightness, and substantially shortens the time of airtight detection.
The object of the present invention is to provide a kind of detection methods of Packaging Case for Satellite air-tightness, and the detection method includes following
Step：
(1) the inside panel inner surface of babinet inside panel and case lid is carried out after Packaging Case for Satellite skeleton and inner covering welding
Dye penetrant inspection detects defect；
(2) and then the sealing of box cover closing lid, the interior inflation of case determine airtight defect by detecting air leakage point on the outside of inside panel
Position；
(3) after waiting for FCL assembly, after FCL closing lid, inflation, detects each airtight defective locations of crossing cabin connector in case；
(4) babinet and case lid separation, are inflated to babinet and case lid intraformational bed, covering and case lid Inner Mongol in detection case body respectively
Skin defective locations.
The airtight defect inspection method of a kind of Packaging Case for Satellite of the present invention, by design for a set of airtight of packing case
Experiment process completely detects the defect for influencing packing case air-tightness, and air seal test is greatly lowered and expends the time.
Description of the drawings
Fig. 1 is background technology Satellite packing box structure schematic diagram；
Fig. 2 is a kind of airtight defect inspection method flow chart of Packaging Case for Satellite of the present invention.
Specific implementation mode
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.It should be understood that following embodiment is only used
In illustrating rather than for limiting the scope of the present invention.
The detailed process implemented according to the present invention is now described in detail, detailed process is shown in shown in figure (2).
(1) in Packaging Case for Satellite babinet inside panel and case lid after the completion of side skin welding equipment, first respectively to babinet inside panel
Surface dye penetrant inspection inspection is carried out with case lid inside panel weld seam, excludes most of defect for influencing packing case air-tightness.
(2) after the completion of FCL machines and before laminated foam filling, babinet and the sealing of case lid closing lid, and block various
Crossing cabin nipple orifice carries out FCL air seal test.For the economy of guarantee test process, air seal test can carry out according to the following steps：
It is first filled with compressed air into case from gas-charging connection, air leakage point is checked using suds；Then nitrogen, pressurize 24 are filled with into case
Hour, if pressure drop is less than License Value, this step terminates, and continues step (3), on the contrary then continue to be filled with helium into case,
Helium mass spectrum leak detection is carried out outside case；Nitrogen is finally filled with into case, pressurize 24 hours stops, instead if pressure drop is less than License Value
The last two steps are then repeated, until pressure drop be less than License Value.This step is for excluding inner covering welding defect.
(3) after the completion of Packaging Case for Satellite integrally assembles, FCL air seal test is carried out, it is airtight for excluding each crossing cabin connector
Defect.Air seal test can carry out according to the following steps：It is filled with helium into case from gas-charging connection, each crossing cabin is checked using helium mass analyzer
Connector air leakage point；Then nitrogen pressurize is filled with into case 24 hours, if pressure drop is less than License Value, FCL air seal test leak detection
It completes, on the contrary then progress (4) step.
(4) this step is standby step, only when step (3) can not completely detect that had an impact Packaging Case for Satellite is airtight
Property defect when just use.Using to packing case interlayer inflating, case is interior to hunt leak, to exclude inside panel in step (2) following process system
Newly generated defect during making.Air seal test can carry out according to the following steps：By being reserved in advance towards babinet, case lid interlayer
Connector is filled with helium in interlayer, and air leakage point is checked out of case using helium mass spectrum；It is filled with nitrogen in FCL, pressurize 24 hours, such as
On the contrary pressure drop is less than License Value, and then FCL air seal test was completed, then above-mentioned steps are repeated, up to 24 hours nitrogen pressurize pressures
Drop is less than License Value.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring the substantive content of the present invention.
