SAS (Serial Attached SCSI) ndi mbadwo watsopano wa ukadaulo wa SCSI. Ndi chimodzimodzi ndi ma hard disk otchuka a Serial ATA (SATA). Imagwiritsa ntchito ukadaulo wa Serial kuti ikwaniritse liwiro lalikulu la kutumiza ndikuwongolera malo amkati mwa kufupikitsa mzere wolumikizira. Pa waya wopanda kanthu, pakadali pano makamaka kuchokera ku magwiridwe antchito amagetsi kuti asiyanitse, ogawika m'magulu 6G ndi 12G, SAS4.0 24G, koma njira yayikulu yopangira ndi yofanana, lero tikubwera kugawana, Mini SAS bare wire introduction and production process control parameters. Pa mzere wa SAS high frequency, impedance, attenuation, loop loss, crosswish ndi zizindikiro zina zotumizira ndizofunikira kwambiri, ndipo pafupipafupi yogwira ntchito ya mzere wa SAS high frequency nthawi zambiri imakhala 2.5GHz kapena kuposerapo pansi pa high frequency, tiyeni tiwone momwe tingapangire mzere wothamanga kwambiri wa SAS.
Tanthauzo la kapangidwe ka chingwe cha SAS
Kutayika kochepa pa chingwe cholumikizirana cha pafupipafupi nthawi zambiri kumapangidwa ndi polyethylene yotulutsa thovu kapena polypropylene yotulutsa thovu ngati zinthu zotetezera kutentha, kondakitala ziwiri zoteteza kutentha zokhala ndi waya wapansi (msika ulinso ndi wopanga WOGWIRITSA NTCHITO njira ziwiri ziwiri) kulowa mu ndege zoyatsira, kunja kwa kondakitala yoteteza kutentha ndi waya wapansi ndi lamba wa polyester wopangidwa ndi aluminiyamu, kapangidwe ka njira zotetezera kutentha ndi kuwongolera njira, kapangidwe ndi zofunikira zamagetsi pakugwiritsa ntchito njira yotumizira mwachangu komanso kusamutsa.
Zofunikira pa owongolera
Kwa SAS, yomwenso ndi mzere wotumizira ma frequency ambiri, kufanana kwa kapangidwe ka gawo lililonse ndiye chinthu chofunikira kwambiri podziwa kuchuluka kwa ma transmission a chingwe. Chifukwa chake, monga kondakitala wa mzere wotumizira ma frequency ambiri, pamwamba pake ndi pozungulira komanso posalala, ndipo kapangidwe ka mkati mwa lattice ndi kofanana komanso kokhazikika, kuti zitsimikizire kufanana kwa magwiridwe antchito amagetsi kutalika; kondakitala ayeneranso kukhala ndi kukana kochepa kwa DC; Nthawi yomweyo ziyenera kupewedwa chifukwa cha mawaya, zida, kapena chipangizo china cholowera mkati chomwe chimapindika nthawi ndi nthawi kapena kupindika kwakanthawi, kusintha ndi kuwonongeka, ndi zina zotero. M'mizere yotumizira ma frequency ambiri, kukana kwa kondakitala kumachitika chifukwa cha kuchepa kwa chingwe (ma frequency parameters base paper 01 - kuchepa) kwa zinthu zazikulu, pali njira ziwiri zochepetsera kukana kwa kondakitala: kumawonjezera m'mimba mwake wa kondakitala, kusankha zinthu za kondakitala ndi resistivity yotsika. Pamene m'mimba mwake wa kondakitala wawonjezeka, kuti akwaniritse zofunikira za impedance yodziwika bwino, m'mimba mwake wakunja wa insulation ndi chinthu chomalizidwa ziyenera kuwonjezeredwa moyenerera, zomwe zimapangitsa kuti ndalama ziwonjezeke komanso kukonza kosasangalatsa. Kawirikawiri amagwiritsidwa ntchito poletsa kukana kwa zinthu zoyendetsera magetsi pa siliva, m'malingaliro, amagwiritsa ntchito dalaivala wa siliva, kukula kwa chinthu chomalizidwa kudzachepa, kudzakhala ndi magwiridwe antchito abwino, koma chifukwa mtengo wa siliva ndi wapamwamba kwambiri kuposa mtengo wa mkuwa, mtengo wake ndi wokwera kwambiri, sitingathe kupanga, kuti tithe kuganizira mtengo wake komanso kukana kwake kotsika, tidagwiritsa ntchito zotsatira za khungu, kuti tipange dalaivala wa chingwe. Pakadali pano, SAS 6G imagwiritsa ntchito dalaivala wa mkuwa wopangidwa ndi zitini kuti ikwaniritse magwiridwe antchito amagetsi, pomwe SAS 12G ndi 24G zimayamba kugwiritsa ntchito dalaivala wopangidwa ndi siliva.
Pakakhala mphamvu yosinthira kapena mphamvu yosinthira yamagetsi mu conductor, vuto la kugawa kwa mphamvu yosagwirizana lidzachitika mu conductor. Pamene mtunda kuchokera pamwamba pa conductor ukuwonjezeka, kuchuluka kwa mphamvu yamagetsi mu conductor kumachepa kwambiri, ndiko kuti, mphamvu yamagetsi mu conductor imakhazikika pamwamba pa conductor. Kuchokera ku mawonekedwe a gawo lopingasa kupita ku mbali ya mphamvu yamagetsi, mphamvu yamagetsi pakati pa conductor kwenikweni ndi zero, ndiko kuti, palibe mphamvu yamagetsi, koma m'mbali mwa conductor m'pamene padzakhala kuyenda pang'ono. Mwachidule, mphamvu yamagetsi imakhazikika mu gawo la "khungu" la conductor, kotero imatchedwa zotsatira za khungu ndipo zotsatira zake zimachitika chifukwa cha kusintha kwa mphamvu yamagetsi kupanga vortex electric field mkati mwa conductor, zomwe zimachotsa mphamvu yamagetsi yoyambirira. Mphamvu ya khungu imapangitsa kukana kwa kondakitala kuwonjezeka ndi kuchuluka kwa mphamvu yosinthira, ndipo zimapangitsa kuti mphamvu yotumizira mawaya ichepe, kugwiritsa ntchito zinthu zachitsulo, koma popanga chingwe cholumikizirana cha pafupipafupi, koma angagwiritse ntchito mfundoyi, pogwiritsa ntchito njira yopaka siliva pamwamba kuti akwaniritse zofunikira zomwezo potengera kuti achepetse kugwiritsa ntchito chitsulo, motero amachepetsa mtengo.
Zofunikira pa kutchinjiriza
Chotenthetsera mpweya chiyenera kukhala chofanana, chomwe chili chofanana ndi cha kondakitala. Kuti mupeze chokhazikika cha dielectric chotsika S ndi tangent ya Angle yotayika ya dielectric, zingwe za SAS nthawi zambiri zimatetezedwa ndi PP kapena FEP, ndipo zingwe zina za SAS zimatetezedwanso ndi thovu. Ngati digiri ya thovu ili yoposa 45%, thovu la mankhwala limakhala lovuta kukwaniritsa, ndipo digiri ya thovu silikhazikika, kotero chingwe choposa 12G chiyenera kugwiritsa ntchito thovu la thupi.
Ntchito yaikulu ya endodermis yokhala ndi thovu lakuthupi ndikuwonjezera kumatirira pakati pa kondakitala ndi kutchinjiriza. Kumatirira kwina kuyenera kutsimikizika pakati pa kondakitala yotchinjiriza ndi kondakitala; apo ayi, mpata wa mpweya udzapangidwa pakati pa kondakitala yotchinjiriza ndi kondakitala, zomwe zimapangitsa kusintha kwa dielectric constant £ ndi tangent value ya dielectric loss Angle.
Zipangizo zotetezera kutentha za polyethylene zimatulutsidwa m'mphuno kudzera mu sikuru, ndipo mwadzidzidzi zimakumana ndi kupsinjika kwa mlengalenga potuluka m'mphuno, ndikupanga mabowo ndi thovu lolumikizira. Zotsatira zake, mpweya umatulutsidwa pakati pa kondakitala ndi potsegulira die, ndikupanga dzenje lalitali la thovu pamwamba pa kondakitala. Kuti athetse mavuto awiri omwe ali pamwambapa, ndikofunikira kutulutsa thovu nthawi imodzi… Khungu lopyapyala limakanikizidwa mkati mwa wosanjikiza wamkati kuti mpweya usatuluke pamwamba pa kondakitala, ndipo wosanjikiza wamkati ukhoza kutseka thovu kuti zitsimikizire kukhazikika kofanana kwa cholumikizira chotumizira, kuti achepetse kuchepa ndi kuchedwa kwa chingwe, ndikuwonetsetsa kuti chingwe chonsecho chili ndi kukhazikika kwabwino. Posankha endodermis, iyenera kukwaniritsa zofunikira za extrusion yopyapyala pansi pa mikhalidwe yopanga mwachangu, kutanthauza kuti, zinthuzo ziyenera kukhala ndi mphamvu zabwino kwambiri zomangirira. LLDPE ndiye chisankho chabwino kwambiri chokwaniritsa izi.
Zofunikira pa zida
Waya wapakati wotetezedwa ndi insulated ndiye maziko a kupanga chingwe, ndipo ubwino wa waya wapakati uli ndi mphamvu yofunika kwambiri pa ndondomeko yotsatira. Pogwiritsira ntchito waya wapakati, zipangizo zopangira ziyenera kukhala ndi ntchito yowunikira ndi kuwongolera pa intaneti kuti zitsimikizire kufanana ndi kukhazikika kwa waya wapakati, ndi magawo a njira yowongolera, kuphatikizapo kukula kwa waya wapakati, mphamvu m'madzi, kukhazikika, ndi zina zotero.
Musanayambe kugwiritsa ntchito mawaya osiyanasiyana, ndikofunikira kutentha lamba wa polyester wodzipangira kuti asungunuke ndikulumikiza guluu wotentha wosungunuka pa lamba wa polyester wodzipangira. Gawo losungunuka lotentha limagwiritsa ntchito chotenthetsera chotenthetsera chamagetsi chowongolera kutentha, chomwe chingasinthe kutentha kotenthetsera moyenera malinga ndi zosowa zenizeni. Pali njira zoyikira zoyimirira ndi zopingasa za chotenthetsera chachikulu. Chotenthetsera choyimirira chingasunge malo, koma waya wozungulira uyenera kudutsa mawilo angapo owongolera okhala ndi ngodya zazikulu kuti alowe mu chotenthetsera, zomwe ndizosavuta kusintha malo oyerekeza a waya woteteza ndi lamba wokutira, zomwe zimapangitsa kuti magwiridwe antchito amagetsi a mzere wotumizira wamagetsi apamwamba achepe. Mosiyana ndi izi, chotenthetsera choyimirira choyimirira chimakhala pamzere womwewo ndi mzere wokutira, chisanalowe mu chotenthetsera, mzere wozungulira umadutsa mawilo ochepa owongolera ndi udindo wofanana ndi dziko lonse, kuluka kwa mzere wokutira sikusintha Ngongo ikadutsa mu gudumu lowongolera, kuonetsetsa kuti malo olumikizira gawo la waya woteteza ndi lamba wokutira ndi kukhazikika. Vuto lokhalo la chotenthetsera chopingasa ndilakuti chimatenga malo ambiri ndipo mzere wopanga ndi wautali kuposa makina ozungulira okhala ndi chotenthetsera choyimirira.
