I-SAS (Serial Attached SCSI) iyisizukulwane esisha sobuchwepheshe be-SCSI. Ifana nama-hard disk e-Serial ATA (SATA) athandwayo. Isebenzisa ubuchwepheshe be-Serial ukufeza isivinini sokudlulisa esiphezulu nokuthuthukisa isikhala sangaphakathi ngokufinyeza umugqa wokuxhuma. Kwintambo engenalutho, okwamanje ikakhulukazi kusukela ekusebenzeni kukagesi ukuhlukanisa, ihlukaniswe phakathi kwe-6G ne-12G, i-SAS4.0 24G, kodwa inqubo yokukhiqiza evamile iyafana, namuhla siza ukwabelana, i-Mini SAS bare wire introduction kanye nemingcele yokulawula inqubo yokukhiqiza. Kumugqa we-frequency ephezulu ye-SAS, impedance, attenuation, loop loss, crosswish kanye nezinye izinkomba zokudlulisa yizona ezibaluleke kakhulu, kanti imvamisa yokusebenza komugqa we-frequency ephezulu ye-SAS ngokuvamile ingama-2.5GHz noma ngaphezulu ngaphansi kwemvamisa ephezulu, ake sibheke ukuthi singayikhiqiza kanjani i-SAS yomugqa wesivinini esiphezulu ofanelekayo.
Incazelo yesakhiwo sekhebula le-SAS
Ukulahlekelwa okuphansi kukhebula lokuxhumana elivame kakhulu kuvame ukwenziwa nge-polyethylene egwebu noma i-polypropylene ene-foam njengezinto zokufaka umswakama, umqhubi ofakwe umswakama amabili onentambo yomhlabathi (imakethe nayo inomkhiqizi OKUSEBENZISA izindlela ezimbili eziphindwe kabili) ezindizeni eziqashiwe, ngaphandle komqhubi ofakwe umswakama kanye nomshini wokugoqa ugesi kanye nebhande le-aluminium foil kanye ne-polyester lamination, ukwakheka kwenqubo yokufakwa umswakama kanye nokulawula inqubo, isakhiwo kanye nezidingo zokusebenza kukagesi zethiyori yokudlulisa ngesivinini esikhulu kanye nokudlulisa.
Izidingo zabaqhubi
Ku-SAS, okuwumugqa wokudlulisa imvamisa ephezulu, ukufana kwesakhiwo sengxenye ngayinye kuyisici esibalulekile sokunquma imvamisa yokudlulisa yekhebula. Ngakho-ke, njengomqhubi womugqa wokudlulisa imvamisa ephezulu, ubuso buyindilinga futhi bubushelelezi, futhi isakhiwo sokuhlelwa kwe-lattice yangaphakathi siyafana futhi sizinzile, ukuqinisekisa ukufana kokusebenza kukagesi ohlangothini lobude; Umqhubi kufanele futhi abe nokumelana kwe-DC okuphansi; Ngesikhathi esifanayo kufanele kugwenywe ngenxa yezintambo, imishini, noma enye idivayisi ukugoba komqhubi wangaphakathi ukugoba ngezikhathi ezithile noma okungajwayelekile, ukuguqulwa kanye nomonakalo, njll., emigqeni yokudlulisa imvamisa ephezulu, ukumelana komqhubi kubangelwa ukuncishiswa kwekhebula (amapharamitha emvamisa ephezulu iphepha eliyisisekelo 01 - ukuncishiswa) kwezici eziyinhloko, kunezindlela ezimbili zokunciphisa ukumelana komqhubi: kwandisa ububanzi bomqhubi, khetha izinto zomqhubi ngokumelana okuphansi. Lapho ububanzi bomqhubi bukhuliswa, ukuze kuhlangatshezwane nezidingo zokuphazamiseka kwesici, ububanzi bangaphandle bokufakwa kokushisa kanye nomkhiqizo oqediwe kufanele bukhuliswe ngokufanele, okuholela ekwandeni kwezindleko kanye nokucutshungulwa okungahambi kahle. Ngokuvamile, i-resistivity ephansi esetshenziswa kakhulu yezinto zokuqhuba isiliva, ngokombono, ISEBENZISA umqhubi wesiliva, ububanzi bomkhiqizo oqediwe buzoncipha, buzoba nokusebenza okuhle kakhulu, kodwa ngenxa yokuthi intengo yesiliva iphakeme kakhulu kunentengo yethusi, izindleko ziphezulu kakhulu, azikwazi ukukhiqiza, ukuze sikwazi ukucabangela intengo kanye nokumelana okuphansi, sisebenzise umphumela wesikhumba, ukuklama umqhubi wekhebula. Njengamanje, i-SAS 6G isebenzisa umqhubi wethusi ofakwe ethini ukuze ihlangabezane nokusebenza kukagesi, kuyilapho i-SAS 12G kanye ne-24G ziqala ukusebenzisa umqhubi wesiliva ofakwe ephepheni.
Uma kukhona insimu yamandla kagesi eshintshanayo noma eshintshanayo kumqhubi, kuzovela isimo sokusatshalaliswa kwamandla kagesi angalingani kumqhubi. Njengoba ibanga ukusuka ebusweni bomqhubi likhula, ubuningi bamandla kagesi kumqhubi buyancipha kakhulu, okungukuthi, amandla kagesi kumqhubi agxila ebusweni bomqhubi. Kusukela ekubukeni kwesigaba esiphambeneyo kuya ekuqondeni kwamandla kagesi, amandla kagesi engxenyeni ephakathi yomqhubi ngokuyisisekelo ayi-zero, okungukuthi, cishe akukho ukugeleza kwamanje, kuphela engxenyeni yomphetho womqhubi kuzoba nokugeleza okuncane. Ngamagama alula, amandla kagesi agxile engxenyeni "yesikhumba" yomqhubi, ngakho-ke kubizwa ngokuthi umphumela wesikhumba futhi umphumela ubangelwa ngokuyisisekelo insimu kagesi kagesi eshintshayo edala insimu kagesi ye-vortex ngaphakathi komqhubi, ekhansela amandla kagesi okuqala. Umphumela wesikhumba wenza ukumelana komqhubi kukhuphuke ngokuvama kokwanda kwamandla ashintshanayo, futhi kuphumela ekwehleni kokusebenza kahle kwamanje kokudluliselwa kwentambo, ukusetshenziswa kwezinsiza zensimbi, kodwa ekwakhiweni kwekhebula lokuxhumana elivame kakhulu, kodwa kungasebenzisa lesi simiso, ngendlela yokufaka isiliva ebusweni ukuze kuhlangatshezwane nezidingo ezifanayo zokusebenza ngaphansi kwesisekelo sokunciphisa ukusetshenziswa kwensimbi, ngaleyo ndlela kuncishiswe izindleko.
Izidingo zokufaka ugesi
Indawo yokushisa kumele ifane, efana neye-conductor. Ukuze uthole i-dielectric constant ephansi i-S kanye ne-tangent ye-dielectric loss Angle, izintambo ze-SAS zivame ukufudumala nge-PP noma i-FEP, kanti ezinye izintambo ze-SAS nazo zifudunyezwa nge-foam. Uma izinga lokuhwamuka lingaphezu kuka-45%, kunzima ukufeza ukuhwamuka kwamakhemikhali, futhi izinga lokuhwamuka alizinzile, ngakho-ke ikhebula elingaphezu kuka-12G kumele lisebenzise ukuhwamuka ngokomzimba.
Umsebenzi oyinhloko we-endodermis enegwebu elingokoqobo ukwandisa ukunamathelana phakathi komqhubi kanye nokufakwa komoya. Ukunamathelana okuthile kumele kuqinisekiswe phakathi kwesendlalelo sokufaka ugesi kanye nomqhubi; ngaphandle kwalokho, kuzokwakhiwa igebe lomoya phakathi kwesendlalelo sokufaka ugesi kanye nomqhubi, okuzoholela ekushintsheni kwe-dielectric constant £ kanye nenani eliqondile le-Angle yokulahlekelwa yi-dielectric.
Izinto zokuvikela i-polyethylene zikhishwa ziye ekhaleni ngesikulufu, bese zivezwa ngokuzumayo kungcindezi yomoya lapho kuphuma ikhala, zakha izimbobo kanye nama-bubble axhumanisayo. Ngenxa yalokho, igesi ikhishwa esikhaleni esiphakathi komqhubi kanye nokuvulwa kwe-die, kwakha imbobo ende ye-bubble ebusweni bomqhubi. Ukuze kuxazululwe izinkinga ezimbili ezingenhla, kuyadingeka ukukhipha ungqimba lwe-foam ngesikhathi esifanayo… Isikhumba esincane sicindezelwa kungqimba lwangaphakathi ukuze kuvinjelwe igesi ukuthi ingakhishwa ebusweni bomqhubi, futhi ungqimba lwangaphakathi lungavala ama-bubble ukuqinisekisa ukuzinza okufanayo kwendawo yokudlulisela, ukuze kuncishiswe ukuncishiswa nokubambezeleka kwekhebula, futhi kuqinisekiswe ukuvimba okuqinile kwesici kulo lonke ulayini wokudlulisela. Ukuze kukhethwe i-endodermis, kumele ihlangabezane nezidingo zokukhishwa kodonga oluncane ngaphansi kwezimo zokukhiqiza okusheshayo, okungukuthi, izinto kumele zibe nezakhiwo ezinhle kakhulu zokudonsa. I-LLDPE iyisinqumo esingcono kakhulu sokuhlangabezana nale mfuneko.
Izidingo zemishini
Intambo eyinhloko efakwe ugesi iyisisekelo sokukhiqizwa kwekhebula, futhi ikhwalithi yentambo eyinhloko inethonya elibaluleke kakhulu enqubweni elandelayo. Enqubweni yokwamukela intambo eyinhloko, imishini yokukhiqiza iyadingeka ukuthi ibe nomsebenzi wokuqapha nokulawula ku-inthanethi ukuqinisekisa ukufana nokuzinza kwentambo eyinhloko, kanye nemingcele yenqubo yokulawula, okuhlanganisa ububanzi bentambo eyinhloko, amandla emanzini, ukugxila, njll.
Ngaphambi kokufaka izintambo ezihlukile, kuyadingeka ukushisa ibhande le-polyester elizinamathiselayo ukuze lincibilikise futhi libophe i-hot melt glue ebhandeni le-polyester elizinamathiselayo. Ingxenye yokuncibilika okushisayo isebenzisa i-preheater yokushisa kagesi elawulwayo, engalungisa izinga lokushisa lokushisa ngokufanele ngokwezidingo zangempela. Kunezindlela zokufaka eziqondile nezivundlile ze-preheater evamile. I-preheater evundlile ingonga isikhala, kodwa intambo egoqayo idinga ukudlula amasondo amaningi alawulayo anama-engeli amakhulu ukuze ingene kwi-preheater, okulula ukushintsha isikhundla esihlobene sentambo eyinhloko yokuvikela kanye nebhande lokusonga, okuholela ekwehleni kokusebenza kukagesi komugqa wokudlulisa ohamba ngesivinini esiphezulu. Ngokuphambene nalokho, i-preheater evundlile isemgqeni ofanayo ne-wrapping line pair, ngaphambi kokungena kwi-preheater, i-line pair idlula kuphela kumasondo ambalwa alawulayo enendima yokuqondanisa kazwelonke, ukuluka kwentambo yokusonga akushintshi i-Angle lapho kudlula esondweni elilawulayo, kuqinisekisa ukuzinza kwesikhundla sokuluka kwesigaba sentambo eyinhloko yokuvikela kanye nebhande lokusonga. Okuwukuphela kwenkinga ye-preheater evundlile ukuthi ithatha isikhala esiningi futhi umugqa wokukhiqiza mude kunomshini ogoqayo one-preheater evundlile.
