Infomesen blong Testing
Ruba sil testing i wan janis blong testim ol kain sil we oli mekem long ruba, mo sevices blong testing long laboratori blong ZHONGXI Testing i kovaem testim ol produksion sil, O-ring, gasket, ol seal ring blong mota, ol seal blong paip, mo ol sil elektromekanikal. Ol ruba sil oli yusum long planti indastri, inkluudem otomotiv, oil en gas, kemikal plante, fud mo drink, famasutikal, aerospes, maritim, mo ol sistem hydraulik mo pneumatik, we sil i mas stopem lekej blong fluid, gas, pressa, ol dasti samting, mo environment sosaes we i kam aotsaed.
Purpos blong ruba sil testing i blong checkem se ol propati blong matirial ruba mo ol dimensen blong sil oli stanap long kondisen blong wok long rael saes, from wan sil we i foldaon save mekem lekej, kontaminesen, daon blong sistem, mo evy expensive repec. Teknik blong testing inkludem testim mechanical propati olsem tensail strength, elongasen, hardness, mo compressen set; testim termal stabeliti blong luk ol senj long propati afta long-taem ekspos long hat; testim kemikal resistens blong luk swelling mo degradesen afta kontak wetem ol, gas, mo solvasen; mo testim dimensen mo surface finis blong sil fo mekem shua se i fittaum wetem ol tolrens blong disain.
Taem ol kastoma sendem sanpol, laboratori i mekem testing long difren step:, inspeksen visual mo idientifikesen blong matirial; seken, testim dimensen mo hardness; thid, mekem testim mechanical olsem tensail, compressen set, mo aging; foa, testim environment eksposjen olsem hat, ozaon, fluid imersen; mo laswan, analisim data mo preparim testing report. Ol koa paramita oli inkludem Shore A hardness, tensail strength long MPa, elongasen long persen, compressen set long persen, servis temperacha renj, mo medya compatibiliti. Ol sample tipikali mas kam long produksion-bec ov sil o fram wan batol blong matirial, mo kastoma save spesifaiem standad we i aplikaem, olsem ISO, ASTM, DIN, JIS, o GB standad, o spesifikesen internal blong manifactura.
Ol Common Question
Hamas dei bae tekem blong finisem wan ruba sil testing?
Turnaraon blong ruba sil testing i save senj depend long namba blong testing item mo taip blong sanpol. Blong testim routine we i inkludem hardness, tensail, mo compressen set, bae i tekem samba 7 go antil 10 woking dei. Taem sanpol i nidim aging test long 70 ia, 168 awo, o 1000 awo eksposjen, o testim fluid imersen long 7 dei, bae turnaraon i go antil 10 go antil 15 woking dei. Taem kastoma wantem ful kaaakterisesen we i inkludem ol aging test long difren temperacha, ozaon eksposjen, compresen stress relaxasen, mo media compatibiliti long difren fluid, bae i tekem 15 woking dei o moa from nidim long-taem kondisenyen. Kastoma save askem long enjini long laboratori blong gaetam plan blong testing we i fittaum wetem timetable blong projek.
Hamas i kostem blong wan ruba sil testing?
Kos blong testing i determine long namba blong testing item we kastoma selektem, no long taip blong sanpol wanwan. Wan paket smol we i inkludem hardness, densiti, mo tensail, kos blong em i loa tumas frantesta ful paket we i inkludem compressen set long multi temperacha, hot air aging, ozaon resistens, fluid imersen, mo FTIR idientifikasen. Ol test item we i nidim long-taem eksposjen o spesal instrumen, olsem compresen stress relaxasen, low temperacha flexibility (TR10, Gehman), o gas permeabiliti, oli kareem kos haeha mo from testing long difren kondisen. Blong gaetam exak kos, kastoma save kontakem enjini blong ZHONGXI Testing, sendem deteil blong produksion, taip blong ruba, standad we i aplikaem, mo lis blong item we oli nidim, mo enjini bae preparim kwotesen blong testing bifolem sampling.
Ol testing item wanwan oli inkludem long ruba sil testing?
Testing item oli depend long taip blong produksion mo standad we i aplikaem. Blong O-ring, item tipikal oli inkludem Shore A hardness, tensail strength, elongasen at break, compressen set, hot air aging, ol stud blong fluid imersen olsem volumen senj, mo dimensen kaaaking. Blong gasket flanj, item oli inkludem sealabiliti long pressa, compressen mo recovery, mo leak reit. Blong shaft seal, item oli inkludem lip forsen, friction toka, mo dinamic leak test. Blong medikal o fud-grad sil, item oli inkludem migrasen test, extractabal, mo biocompatibiliti screening. Kastoma save spesifaiem standad international, nasional, o internal, mo enjini bae helpem blong define paket blong item we i relevanm long aplikasen blong sil mo matirial ruba we i mekem.
Hamas samtaon blong sanpol mas preparem blong wan ruba sil testing?
Namba blong sanpol i depend long testing item we i selektem. Blong testim tensail, laboratori i nidim samba 15 go antil 25 pies O-ring o dumbbell specimem fram shi blong matirial, o samba 200 go antil 500 gram ruba blong mekem specimen fram. Blong testim compressen set, i nidim samba 3 pies blong wanwan kondisen, mo samba 9 pies taem oli test long tri temperacha. Blong testim dimensen mo hardness, 5 pies i inaf. Blong fluid imersen, specimen smol we samba 50 gram i inaf blong wanwan fluid. Long adisen, i gud blong sendem wan pis blong produksion finis olgeta, from testing long surface koating, o densiti i nidim specimem we surface em i stap olsem long prodaksen. Kastoma save askem long enjini blong gaetam exak lis blong sampling bifolem sendem.
