I-SAS (Serial Attached SCSI) sisizukulwana esitsha setekhnoloji ye-SCSI. Ifana neediski eziqinileyo ze-Serial ATA (SATA) ezidumileyo. Isebenzisa itekhnoloji ye-Serial ukufikelela kwisantya esiphezulu sokudlulisa kunye nokuphucula indawo yangaphakathi ngokunciphisa umgca woqhagamshelo. Kwintambo engenanto, okwangoku ikakhulu ukusuka ekusebenzeni kombane ukwahlulahlula, yahlulwe kwi-6G kunye ne-12G, i-SAS4.0 24G, kodwa inkqubo yemveliso eqhelekileyo iyafana, namhlanje siza kwabelana, iMini SAS bare wire introduction kunye neeparamitha zolawulo lwenkqubo yemveliso. Kwimigca ye-SAS ephezulu, i-impedance, i-attenuation, i-loop loss, i-crosswish kunye nezinye izalathisi zokudlulisa zezona zibalulekileyo, kwaye i-SAS high frequency line frequency frequency isebenza ngokubanzi kwi-2.5GHz okanye ngaphezulu phantsi kwe-high frequency, makhe sijonge indlela yokuvelisa umgca we-SAS ofanelekileyo wesantya esiphezulu.
Inkcazelo yolwakhiwo lwentambo ye-SAS
Ilahleko ephantsi kwintambo yonxibelelwano oluqhelekileyo idla ngokwenziwa nge-polyethylene ekhupha ulwelo okanye i-polypropylene ekhupha ulwelo njengezinto zokukhusela, umqhubi ogqunyiweyo ezimbini onentambo yomhlaba (imarike ikwanayo nomenzi OKUSEBENZISA iindlela ezimbini eziphindwe kabini) ukuya kwiindiza ze-charter, ngaphandle komqhubi ogqunyiweyo kunye nentambo yomhlaba kunye ne-aluminium foil kunye ne-lamination polyester belt, uyilo lwenkqubo yokukhusela kunye nolawulo lwenkqubo, isakhiwo kunye neemfuno zokusebenza kombane zethiyori yokudlulisa ngesantya esiphezulu kunye nokudlulisa.
Iimfuno zabaqhubi
Kwi-SAS, ekwangumgca wokudlulisa ohamba rhoqo, ukufana kwesakhiwo senxalenye nganye yeyona nto iphambili ekumiseleni imvamisa yokudlulisa yentambo. Ke ngoko, njengomqhubi womgca wokudlulisa ohamba rhoqo, umphezulu ujikelezile kwaye ugudile, kwaye isakhiwo solungiselelo lwangaphakathi lwelatisi siyafana kwaye sizinzile, ukuqinisekisa ukufana kokusebenza kombane kwicala lobude; Umqhubi kufuneka abe nokumelana okuphantsi kwe-DC; Kwangaxeshanye kufuneka kuthintelwe ngenxa yezintambo, izixhobo, okanye esinye isixhobo ukugoba komqhubi wangaphakathi okanye ukugoba okungahambi kakuhle, ukuguquguquka kunye nomonakalo, njl.njl., kwimigca yokudlulisa ohamba rhoqo, ukumelana komqhubi kubangelwa kukuncipha kwentambo (iiparameters zemvamisa ephezulu iphepha lesiseko 01 - ukuncitshiswa) kwezinto eziphambili, kukho iindlela ezimbini zokunciphisa ukumelana komqhubi: ukwandisa ububanzi bomqhubi, khetha izinto zomqhubi ngokumelana okuphantsi. Xa ububanzi bomqhubi bunyusiwe, ukuze kuhlangatyezwane neemfuno ze-impedance yempawu, ububanzi bangaphandle bokugquma kunye nemveliso egqityiweyo kufuneka bunyuswe ngokufanelekileyo, okubangela ukwanda kweendleko kunye nokucutshungulwa okungahambi kakuhle. Isetyenziswa rhoqo njenge-resistivity ephantsi yezinto eziqhuba isilivere, ngokwethiyori, ISEBENZISA umqhubi wesilivere, ububanzi bemveliso egqityiweyo buya kuncipha, buya kuba nokusebenza okuhle, kodwa ngenxa yokuba ixabiso lesilivere liphezulu kakhulu kunexabiso lethusi, ixabiso liphezulu kakhulu, alikwazi ukuvelisa, ukuze sikwazi ukuqwalasela ixabiso kunye ne-resistivity ephantsi, sisebenzise isiphumo sesikhumba, ukuyila umqhubi wekhebula. Okwangoku, i-SAS 6G isebenzisa umqhubi wethusi ofakwe kwitini ukuhlangabezana nokusebenza kombane, ngelixa i-SAS 12G kunye ne-24G ziqala ukusebenzisa umqhubi wesilivere ofakwe kwisinyithi.
Xa kukho intsimi yamandla atshintshanayo okanye i-electromagnetic etshintshanayo kwi-conductor, isiganeko sokusasazwa kwamandla angalinganiyo siya kwenzeka kwi-conductor. Njengoko umgama ukusuka kumphezulu womqhubi ukhula, uxinano lwamandla kumqhubi luyancipha ngokukhawuleza, oko kukuthi, amandla akhoyo kwi-conductor agxila kumphezulu womqhubi. Ukusuka kumbono wecandelo elinqamlezileyo ukuya kwicala lamandla akhoyo, amandla akhoyo kwinxalenye ephakathi yomqhubi ngokusisiseko yi-zero, oko kukuthi, akukho flow yamandla akhoyo, kuphela kwinxalenye yomphetho womqhubi kuya kuba ne-sub-flow. Ngamazwi alula, amandla akhoyo agxininiswe kwinxalenye "yesikhumba" yomqhubi, ngoko ke ibizwa ngokuba yi-skin effect kwaye isiphumo sibangelwa yi-electromagnetic field etshintshayo edala i-vortex electrical field ngaphakathi komqhubi, erhoxisa amandla akhoyo okuqala. Isiphumo solusu senza ukuba ukumelana komqhubi kunyuke ngokunyuka kombane otshintshanayo, kwaye kukhokelela ekunciphiseni ukusebenza kakuhle kothumelo lwentambo, kusetyenziswa izixhobo zesinyithi, kodwa kuyilo lweentambo zonxibelelwano ezisebenzisa amaxesha amaninzi, kodwa banokusebenzisa eli thuba, ngendlela yokugquma isilivere kumphezulu ukuze bahlangabezane neemfuno ezifanayo zokusebenza phantsi kwengcamango yokunciphisa ukusetyenziswa kwesinyithi, ngaloo ndlela banciphise iindleko.
Iimfuno zokuvala ubushushu
Isixhobo sokukhusela kufuneka sifane, esifana nesomqhubi. Ukuze ufumane i-dielectric constant ephantsi i-S kunye ne-tangent ye-dielectric loss Angle, iintambo ze-SAS zihlala zigqunywe yi-PP okanye i-FEP, kwaye ezinye iintambo ze-SAS nazo zigqunywe yi-foam. Xa iqondo lokukhupha i-foam lingaphezulu kwe-45%, kunzima ukufikelela kwi-chemical foam, kwaye iqondo lokukhupha i-foam alizinzanga, ngoko ke intambo engaphezulu kwe-12G kufuneka isebenzise i-physical foam.
Umsebenzi oyintloko we-endodermis enefoam ebonakalayo kukwandisa ukunamathelana phakathi komqhubi kunye nokufakwa kwe-insulation. Ukunamathelana okuthile kufuneka kuqinisekiswe phakathi komaleko wokufaka i-insulation kunye nomqhubi; kungenjalo, kuya kubakho umsantsa womoya phakathi komaleko wokufaka i-insulation kunye nomqhubi, nto leyo ekhokelela kutshintsho kwi-dielectric constant £ kunye nexabiso le-tangent le-Angle yokulahleka kwe-dielectric.
Izinto zokukhusela i-polyethylene zithunyelwa empumlweni ngeskrufu, kwaye ngequbuliso zityhileke kuxinzelelo lomoya ekuphumeni kwempumlo, zenze imingxunya kunye namaqamza adibanisayo. Ngenxa yoko, igesi ikhutshwa kwindawo ephakathi komqhubi kunye nokuvulwa kwedayethi, yenze umngxuma omde weqamza phezu komphezulu womqhubi. Ukusombulula ezi ngxaki zimbini zingasentla, kuyimfuneko ukukhupha umaleko we-foam ngaxeshanye… Ulusu olubhityileyo lucinezelwa kumaleko angaphakathi ukuthintela igesi ekukhutshweni kumphezulu womqhubi, kwaye umaleko ongaphakathi unokutywina amaqamza ukuqinisekisa uzinzo olufanayo lwesixhobo sokudlulisa, ukuze kuncitshiswe ukuncitshiswa kunye nokulibaziseka kwentambo, kwaye kuqinisekiswe ukuthintelwa okuzinzileyo kwimida yokudlulisa yonke. Ukukhetha i-endodermis, kufuneka ihlangabezane neemfuno zokukhupha udonga oluncinci phantsi kweemeko zemveliso ekhawulezayo, oko kukuthi, izinto kufuneka zibe neempawu zokuxinana ezibalaseleyo. I-LLDPE yeyona ndlela ilungileyo yokuhlangabezana nale mfuneko.
Iimfuno zezixhobo
Intambo engundoqo egqunywe yi-insulated sisiseko semveliso yekhebula, kwaye umgangatho wentambo engundoqo unempembelelo ebaluleke kakhulu kwinkqubo elandelayo. Kwinkqubo yokwamkela intambo engundoqo, izixhobo zemveliso kufuneka zibe nomsebenzi wokubeka esweni nokulawula kwi-intanethi ukuqinisekisa ukufana kunye nokuzinza kwentambo engundoqo, kunye neeparamitha zenkqubo yokulawula, kubandakanya ububanzi bentambo engundoqo, umthamo emanzini, ukuqina, njl.
Ngaphambi kokufaka iintambo ezahlukeneyo, kuyimfuneko ukufudumeza ibhanti yepolyester ezincamathelayo ukuze inyibilike kwaye ibophe i-hot melt adhesive kwibhanti yepolyester ezincamathelayo. Inxalenye enyibilikayo eshushu isebenzisa i-preheater yokufudumeza elawulwayo yobushushu obulawulwayo, enokulungisa ubushushu bokufudumeza ngokufanelekileyo ngokweemfuno zokwenyani. Kukho iindlela zokufakela ngokuthe nkqo nangokuthe tye kwi-preheater eqhelekileyo. I-preheater ethe nkqo inokonga indawo, kodwa i-wiring winding kufuneka idlule kumavili amaninzi alawulayo anee-engile ezinkulu ukuze ingene kwi-preheater, okulula ukutshintsha indawo ehambelanayo ye-insulating core wire kunye ne-wrap belt, okubangela ukwehla kokusebenza kombane komgca wokudlulisa ohamba rhoqo. Ngokwahlukileyo koko, i-preheater ethe tye ikumgca ofanayo ne-wrap line pair, ngaphambi kokuba ingene kwi-preheater, i-line pair idlula kuphela kumavili ambalwa alawulayo enendima yokulungelelaniswa kwesizwe, i-wrap line knitting ayitshintshi i-Angle xa idlula kwivili elilawulayo, iqinisekisa uzinzo lwendawo yokuluka yesigaba se-insulating core wire kunye ne-wrap belt. Eyona nto imbi nge-horizontal preheater kukuba ithatha indawo engaphezulu kwaye umgca wemveliso mde kunomatshini ojijayo one-preheater ethe nkqo.
