I-SAS(i-Serial Attached SCSI) sisizukulwana esitsha sobuchwepheshe be-SCSI.Iyafana neseriyeli edumileyo ATA(SATA) hard disks.Isebenzisa iteknoloji ye-Serial ukufezekisa isantya esiphezulu sothumelo kunye nokuphucula indawo yangaphakathi ngokunciphisa umgca wokudibanisa.Kuba ucingo olungenanto, okwangoku ikakhulu ukusuka ekusebenzeni kombane ukwahlula, yahlulwe yaba yi-6G kunye ne-12G, i-SAS4.0 24G, kodwa inkqubo yemveliso yesiqhelo iyafana, namhlanje siza ukwabelana, i-Mini SAS ingabizi ingeniso yocingo kunye nemilinganiselo yokulawula inkqubo yemveliso. .Kwi-SAS i-high frequency line, i-impedance, i-attenuation, ilahleko ye-loop, i-crosswish kunye nezinye izikhombisi zothumelo zezona zibalulekileyo, kwaye i-SAS i-frequency ye-frequency ye-SAS ephezulu yokusebenza rhoqo yi-2.5GHz okanye ngaphezulu phantsi kwe-frequency ephezulu, makhe sijonge indlela yokuvelisa i-frequency umgca wesantya esiphezulu esifanelekileyo SAS.
Inkcazo yesakhiwo sentambo ye-SAS
Ilahleko ephantsi kwintambo yonxibelelwano yefrikhwensi ephezulu idla ngokwenziwa ngepolyethylene ebilayo okanye i-polypropylene enogwebu njengezixhobo zokugquma, i-conductor ezimbini ezigqunyiweyo ezinocingo oluphantsi (imarike ikwanayo nomvelisi USEBENZISA iindlela ezimbini eziphindwe kabini) kwiinqwelomoya zokutshatha, ngaphandle kwe-conductor egqunyiweyo kunye nomhlaba. i-wire winding kunye ne-aluminium foil kunye ne-lamination polyester ibhanti, ukuyila inkqubo yokufakelwa kunye nokulawulwa kwenkqubo, ulwakhiwo kunye neemfuno zokusebenza kombane ze-high-speed transmission and transfer theory.
Iimfuno zabaqhubi
Kwi-SAS, ekwangumgca ophezulu wokuhanjiswa kwamaza, ukufana kwesakhiwo secandelo ngalinye yinto ephambili yokumisela ukuhanjiswa kwentambo.Ngoko ke, njengomqhubi we-high-frequency transmission line, umphezulu ujikelezileyo kwaye ugudileyo, kwaye isakhiwo sangaphakathi se-lattice sangaphakathi siyafana kwaye sizinzile, ukuqinisekisa ukufana kokusebenza kombane kwindlela yobude;I-conductor kufuneka kwakhona ibe nokumelana okuphantsi kwe-DC;Kwangaxeshanye kufuneka kuphetshwe ngenxa yocingo, izixhobo, okanye esinye isixhobo sokugoba kwangaphakathi kwesixhobo sokugoba ngamaxesha athile okanye ukugoba, ukuguqulwa nomonakalo, njl. iphepha 01 - attenuation) kwizinto eziphambili, kukho iindlela ezimbini zokunciphisa ukuchasana komqhubi: ukwandisa i-conductor diameter, khetha i-conductor material with low resistivity.Xa i-diameter ye-conductor inyuswa, ukuze kuhlangatyezwane neemfuno ze-impedance yeempawu, i-diameter yangaphandle ye-insulation kunye nemveliso egqityiweyo kufuneka yandiswe ngokufanelekileyo, okukhokelela ekunyuseni kweendleko kunye nokungahambi kakuhle.Ngokuqhelekileyo kusetyenziswa resistivity ephantsi izinto conductive zesilivere, ngokwethiyori, USEBENZISA umqhubi wesilivere, imveliso egqityiweyo ububanzi iya kunciphisa, iya kuba nentsebenzo enkulu, kodwa ngenxa yokuba ixabiso lesilivere liphezulu kakhulu kunexabiso lobhedu, ixabiso eliphezulu kakhulu, ayikwazi ukuvelisa, ukwenzela ukuba sikwazi ukuqwalasela ixabiso kunye nokumelana okuphantsi, sasebenzisa umphumo wesikhumba, ukuyila umqhubi wentambo, Okwangoku, i-SAS 6G isebenzisa umqhubi wobhedu owenziwe ngetoti ukuhlangabezana nokusebenza kombane, ngelixa i-SAS 12G kunye ne-24G iqala ukusebenzisa i-conductor enesilivere.
Xa kukho indawo etshintshayo yangoku okanye i-electromagnetic field kwi-conductor, isenzeko sokusasazwa kokungalingani kwangoku kuya kwenzeka kwi-conductor.Njengoko umgama ovela kumphezulu womqhubi ukhula, ukuxinana kwangoku kwi-conductor kuncipha ngokukhawuleza, oko kukuthi, i-current in conductor igxininise kumphezulu womqhubi.Ukusuka kwimboniselo yecandelo lomnqamlezo ngokwe-perpendicular ukuya kwicala le-current, intensity yangoku kwindawo esembindini ye-conductor ngu-zero, oko kukuthi, akukho phantse ukuhamba kwangoku, kuphela kwinxalenye yomqhubi we-edge iya kuba ne-sub. -hamba.Ngamagama alula, umsinga ugxininiswe kwinxalenye "yesikhumba" yomqhubi, ngoko ke ibizwa ngokuba yimpembelelo yesikhumba kwaye umphumo ubangelwa ngokusisiseko kwintsimi ye-electromagnetic eyenza intsimi yombane ye-vortex ngaphakathi kwe-conductor, ecima umbane wokuqala. .Impembelelo yesikhumba yenza ukuchasana kwe-conductor kunyuke ngokuphindaphindiweyo kokunyuka kwangoku okutshintshisayo, kwaye kubangele ukuncipha kokusebenza kwangoku kokuhanjiswa kwecingo, sebenzisa izixhobo zetsimbi, kodwa kuyilo lwentambo yoqhagamshelwano oluphezulu, kodwa unokuthatha ithuba loku. umgaqo, kunye nendlela yokubeka isilivere kumphezulu ukuhlangabezana neemfuno ezifanayo zokusebenza phantsi kwesiseko sokunciphisa ukusetyenziswa kwesinyithi, ngaloo ndlela ukunciphisa iindleko.
Iimfuno ze-insulation
I-insulation medium kufuneka ibe yinto efanayo, efana neyomqhubi.Ukufumana i-dielectric ephantsi rhoqo i-S kunye ne-tangent ye-dielectric loss Angle, iintambo ze-SAS zihlala zifakwe kwi-PP okanye i-FEP, kwaye ezinye iintambo ze-SAS nazo zifakwe kwi-foam.Xa idigri yogwebu ingaphezulu kwe-45%, kunzima ukuphumeza ugwebu lwekhemikhali, kwaye iqondo logwebu aluzinzanga, ngoko ke intambo engaphezulu kwe-12G kufuneka ikhuphe amagwebu emzimbeni.
Umsebenzi ophambili we-endodermis enegwebu ngokwasemzimbeni kukwandisa ukunamathela phakathi komqhubi kunye nokugquma.Ukubambelela okuthile kufuneka kuqinisekiswe phakathi kwe-insulating layer kunye nomqhubi;ngaphandle koko, i-gap yomoya iya kwenziwa phakathi kwe-insulating layer kunye ne-conductor, okubangelwa utshintsho kwi-dielectric constant £ kunye nexabiso le-tangent ye-dielectric loss Angle.
Izinto zokugquma i-polyethylene zikhutshelwa empumlweni nge-screw, kwaye ngokukhawuleza zibonakaliswe kuxinzelelo lwe-atmospheric ekuphumeni kwempumlo, zenza imingxuma kunye namaqamza okudibanisa.Ngenxa yoko, igesi ikhutshwa kwisithuba phakathi komqhubi kunye nokuvulwa kokufa, okwenza umngxuma omde we-bubble phezu kobuso bomqhubi.Ukusombulula ezi ngxaki zimbini zingasentla, kuyimfuneko ukukhupha umaleko we-foam ngaxeshanye… Ulusu olubhityileyo lucinezelwa kumaleko angaphakathi ukuthintela ukukhutshwa kwerhasi kumphezulu womqhubi, kwaye umaleko wangaphakathi unokutywina amaqamza. ukuqinisekisa ukuzinza okufanayo kwendlela yothumelo, ukwenzela ukunciphisa ukuthotywa kunye nokulibaziseka kwentambo, kunye nokuqinisekisa ukungazinzi kwempawu zokuthintela kuwo wonke umgca wothumelo.Ukukhethwa kwe-endodermis, kufuneka ihlangabezane neemfuno ze-extrusion yodonga oluncinci phantsi kweemeko zemveliso yesantya esiphezulu, oko kukuthi, izinto eziphathekayo kufuneka zibe neempawu ezintle kakhulu.I-LLDPE lolona khetho lulungileyo lokuhlangabezana nale mfuneko.
Iimfuno zezixhobo
I-insulated core wire isiseko sokuvelisa i-cable, kwaye umgangatho we-core wire unempembelelo ebaluleke kakhulu kwinkqubo elandelayo.Kwinkqubo yokwamkela i-core wire, izixhobo zokuvelisa kufuneka zibe ne-intanethi yokubeka iliso kunye nomsebenzi wokulawula ukuqinisekisa ukufana kunye nokuzinza kwe-core wire, kunye neeparitha zenkqubo yokulawula, kubandakanywa nobubanzi be-core wire, i-capacitance emanzini, i-concentricity, njl.
Ngaphambi kokudibanisa i-wiring, kuyimfuneko ukufudumeza ibhanti le-polyester elizincamatheleyo ukuze linyibilike kwaye libophe i-adhesive eshushu inyibilikayo kwibhanti ye-self-adhesive polyester.Indawo eshushu yokunyibilika ithatha iqondo lobushushu elilawulekayo lobushushu be-electromagnetic heatheater, enokulungelelanisa ubushushu ngokufanelekileyo ngokweemfuno zokwenyani.Kukho iindlela zofakelo ezithe nkqo nezithe tyaba ze-preheater ngokubanzi.I-preheater ethe nkqo inokugcina indawo, kodwa ucingo olujikajikayo kufuneka ludlule kumavili alawulayo amaninzi aneengile ezinkulu zokungena kwi-preheater, ekulula ukutshintsha indawo ehambelanayo yocingo olungundoqo olukhuselayo kunye nebhanti lokusonga, okukhokelela ekwehleni kwesixhobo sokufudumeza. ukusebenza kombane kumgca wokuhanjiswa kwesantya esiphezulu.Ngokwahlukileyo, i-preheater ethe tyaba ikumgca ofanayo kunye nesibini somgca wokusonga, ngaphambi kokungena kwi-preheater, isibini somgca sidlula kuphela amavili ambalwa alawulayo kunye nendima yolungelelwaniso lwesizwe, ukunitha komgca wokusonga akutshintshi i-Angle xa udlula. ngevili elilawulayo, ukuqinisekisa uzinzo lwendawo yokunitha yesigaba socingo olukhuselayo kunye nebhanti lokusonga.Okukuphela kokungalunganga kwe-preheater ethe tyaba kukuba ithatha indawo eninzi kwaye umgca wemveliso ude kunomatshini wokujija onesifudumezi esithe nkqo.
