Ikhebula le-drag chain, njengoba igama liphakamisa, ikhebula elikhethekile elisetshenziswa ngaphakathi kweketango lokudonsa. Ezimeni lapho amayunithi emishini edinga ukuya emuva naphambili, ukuvimbela ukubosheka kwekhebula, ukuguga, ukudonsa, ukuhuqwa, nokuhlakazeka, izintambo zivame ukufakwa ngaphakathi kwamaketanga okudonsa ikhebula. Lokhu kunikeza isivikelo kuzintambo, okuzivumela ukuthi ziye emuva naphambili kanye neketango lokuhudula ngaphandle kokuguga okubalulekile. Le ntambo eguquguqukayo kakhulu eklanyelwe ukunyakaza kanye neketango lokuhudula ibizwa ngokuthi ikhebula le-drag chain. Idizayini yezintambo zokudonsa kufanele icabangele izidingo ezithile ezibekwe imvelo yeketango lokudonsa.
Ukuze uhlangabezane nomnyakazo oqhubekayo wokubuyela emuva naphambili, ikhebula elijwayelekile lokudonsa liqukethe izingxenye ezimbalwa:
Isakhiwo Socingo Lwethusi
Amakhebuli kufanele akhethe umqhubi oguquguquka kakhulu, ngokuvamile, uma umqhubi abe mncane, ngcono ukuguquguquka kwekhebula. Kodwa-ke, uma ikhondukta izacile kakhulu, kuzoba khona into ethile lapho amandla aqinile nokusebenza kokushwibeka konakala. Uchungechunge lokuhlola lwesikhathi eside lufakazele ubukhulu obufanele, ubude, nokuhlanganiswa kokuvikela komqhubi oyedwa, okunikeza amandla angcono kakhulu okubamba. Ikhebula kufanele likhethe umqhubi ovumelana nezimo kakhulu; ngokuvamile, umqhubi mncane kakhulu, ngcono ukuguquguquka kwentambo. Kodwa-ke, uma i-conductor incane kakhulu, izintambo ezinama-multi-core stranded ziyadingeka, okwandisa ubunzima bokusebenza kanye nezindleko. Ukufika kwezintambo ze-copper foil kuyixazulule le nkinga, ngakho kokubili izakhiwo ezingokwenyama nezikagesi kuyisinqumo esifanele uma kuqhathaniswa nezinto ezitholakalayo njengamanje emakethe.
I-Core Wire Insulation
Izinto zokufakelwa ngaphakathi kwekhebula akumele zinamathele kwenye futhi zidinga ukuba nezakhiwo ezinhle kakhulu zomzimba, ukushwibeka okuphezulu, namandla aphezulu okudonsa. Okwamanje, ishintshiweI-PVCkanye nezinto ze-TPE zikufakazele ukwethembeka kwazo enqubweni yokufaka isicelo sezintambo zokudonsa, ezihamba ngezigidi zemijikelezo.
Isikhungo se-Tensile
Kukhebula, ingqikithi emaphakathi kufanele ngokufanelekile ibe nesiyingi esimaphakathi sangempela esisekelwe enanini lama-cores kanye nesikhala endaweni ngayinye yokuwela intambo ewumgogodla. Ukukhethwa kwemicu ehlukahlukene yokugcwalisa,izintambo ze-kevlar, nezinye izinto ezisetshenziswayo ziba semqoka kulesi simo.
Isakhiwo socingo oluyintambo kufanele siboshwe endaweni eqinile eqinile enephimbo elixhumene elifanele. Kodwa-ke, ngenxa yokusetshenziswa kwezinto zokufakelwa, i-wire stranded structure kufanele yakhelwe ngokusekelwe esimweni sokunyakaza. Kusukela ezintanjeni eziyi-12, kufanele kusetshenziswe indlela yokusonta ehlanganisiwe.
Ukuvikela
Ngokulungiselela i-engeli yokuluka, isendlalelo esivikelayo silukwa ngokuqinile ngaphandle komgodla wangaphakathi. Ukweluka okuxekethile kunganciphisa ikhono lokuvikela le-EMC, futhi isendlalelo sokuvikela sihluleka ngokushesha ngenxa yokwephuka kwesivikelo. Isendlalelo esivikelekile esilukwe ngokuqinile futhi sinomsebenzi wokumelana ne-torsion.
Igobolondo langaphandle elenziwe ngezinto eziguquliwe ezahlukahlukene linemisebenzi eyahlukene, okuhlanganisa ukumelana ne-UV, ukumelana nezinga lokushisa eliphansi, ukumelana nowoyela, nokwenza ngcono izindleko. Kodwa-ke, wonke la mashethi angaphandle ahlanganyela isici esivamile: ukumelana nokuhuzuka okuphezulu nokunganamatheli. Umgodla wangaphandle kufanele uguquguquke kakhulu ngenkathi unikeza ukwesekwa, futhi, yiqiniso, kufanele ube nokumelana nokucindezela okuphezulu. Igobolondo langaphandle elenziwe ngezinto eziguquliwe ezahlukahlukene linemisebenzi ehlukene, okuhlanganisa ukumelana ne-UV, ukumelana nezinga lokushisa eliphansi, ukumelana nowoyela, nokwenza ngcono izindleko. Kodwa-ke, wonke la mashethi angaphandle ahlanganyela isici esivamile: ukumelana nokuhuzuka okuphezulu nokunganamatheli. Umgodla wangaphandle kufanele uguquke kakhulu.
