Yini Eyenza Isixhumi Sentambo Singangeni Manzi Ngempela Ukuze Sisetshenziswe Emanzini Nasezimotweni?
Noma ubani oke walandela iphutha eliqhubekayo esikebheni noma enqoleni uyazi ukuthi imbangela ivame ukuba yi-splice ebolile. Amanzi athola indlela yawo yokuxhumana, ithusi liyaqina, ukumelana kuyakhuphuka, bese isekethe iqala ukuziphatha kabi. "Amanzi angangeni" anyatheliswa emaphaketheni amaningi ezixhumi, kodwa akuwona wonke umkhiqizo ozuzayo. Nakhu okwenza isixhumi sentambo singangeni manzi, nokuthi ungasithola kanjani isivalo esisinda iminyaka eminingi yomswakama, usawoti, kanye nokudlidliza.
Kungani izixhumi ezivamile zihluleka ngaphandle
Isixhumi esijwayelekile se-crimp senza i-joint kagesi eqinile, kodwa ayenzi lutho ukuvimba amanzi ukuthi angangeni. Umswakama ugoqa imicu ye-conductor ngesenzo se-capillary, uhamba ngaphansi kwe-insulation ngale kwe-slice ebonakalayo. Uma amanzi efika ethusi, ukugqwala kuyaqala, futhi endaweni enosawoti kuyashesha kakhulu. Umphumela uba i-conductor eluhlaza, ephukile kanye nokuxhumana okwehluleka kancane ngokwanele ukuba kukhungathekise ukuxilonga.
Yingakho ukufakwa kwezasolwandle, kwezimoto, kwezolimo, nangaphandle kudinga izixhumi ezenzelwe ngqo ukuvala i-splice, hhayi nje ukuyihlanganisa. Umgomo uwukuvimbela amanzi ukuthi angafiki kumqhubi.
Indlela yokufaka uphawu nokushisa kwe-solder Izixhumi ze-Shrink dala uphawu
Isixhumi sesivalo se-solder sihlanganisa imisebenzi emibili esikhwameni esisodwa. Ngaphakathi kwepayipi elikhanyayo lokunciphisa ukushisa kuhleli indandatho yesivalo esinokushisa okuphansi, esizungezwe yizindandatho zesinamathiseli esincibilikisa ukushisa. Uhlubula bese ufaka ama-conductor amabili ukuze ahlangane ngaphakathi kwe- Indandatho Yomshisi, bese ufaka ukushisa. Izinto ezintathu zenzeka ngokulandelana: ithubhu liyancipha liqine, indandatho ye-solder iyancibilika bese igeleza ezintanjeni ukuze izibophe ngogesi, bese izindandatho ze-glue ziyancibilika bese zenza uphawu olungangeni manzi ekugcineni ngakunye kwesikhafu.
Leso sivalo sokunamathela siyingxenye eletha ukuvimbela amanzi. Lapho ukuncibilika okushisayo kuphola, kukhiyeka ku-insulation yentambo kanye nepayipi, ukuvala indlela amanzi abezohamba ngayo nomqhubi. Isixhumi esilula se-heat-shrink butt sisebenza ngendlela efanayo, sisebenzisa ipayipi elinamathelayo ukuvala ijoyinti eligobekile ngisho nangaphandle kwendandatho yokugoqa. Zombili izindlela zihlanganyela isimiso esifanayo: hlanganisa isibopho sikagesi esithembekile nesithiyo somswakama sokunamathela.
Ukuqonda izilinganiso ze-IP
Uma isixhumi sithi sisebenza kahle ngokungangeni manzi, funa isilinganiso se-IP (Ingress Protection) kunokuba igama ngokwalo livele. Isilinganiso sinezinombolo ezimbili. Esokuqala simboza izinto eziqinile nothuli; esesibili simboza amanzi. Kwabaxhumanisi bezintambo, inombolo yamanzi yiyona ebalulekile. Isilinganiso esizungeze i-IP67 sisho ukuthi uxhumano oluvaliwe lungamelana nokucwiliswa kwesikhashana emanzini ngaphansi kwezimo ezichaziwe, okuhambisana nezinhlayiya eziningi zasolwandle nezezimoto. Izilinganiso eziphakeme zibonisa ukumelana nokuchayeka emanzini okunamandla.
Phatha izilinganiso ze-IP njengesiqondiso esithatha ukufakwa okufanele. Isixhumi esikwazi ukuvala kahle sisavuza uma sishiswa ngokungalingani, uma inhlaka ingagelezi ngokugcwele, noma uma ucingo lungalingani kahle nesiketi. Isilinganiso sichaza amandla omkhiqizo; ubuchwepheshe bakho bunquma ukuthi uyafinyelela yini kuwo.
Ukufaka izixhumi ezingangeni manzi ngendlela efanele
Ukuvalwa kuncike ngokuphelele ekufudumaleni okufanele, ngakho-ke lesi sinyathelo sivuza ukunakekelwa okuncane. Hlukanisa umqhubi ngamunye ubude obuchazwe kusixhumi, bese ugoqa iziphetho ezivalekile ukuze kungabikho micu ephumayo. Faka womabili ama-conductor ukuze ahlangane ngaphakathi kwe-solder ephakathi noma indawo ye-crimp. Ukuze uthole isixhumi se-heat shrink sesitayela se-crimp, crimp kuqala, bese ufudumala.
Faka ukushisa ngokulinganayo ngesibhamu sokushisa, ujikeleze umkhono kunokuba uqondise endaweni eyodwa. Qaphela izinkomba ezibonakalayo: ithubhu lidonsa kahle ocingweni, indandatho ye-solder iyancibilika bese igeleza ezintanjeni ukuze ijoyinti libukeke njengensimbi efanayo, bese kuvela i-bead encane ye-glue ekugcineni kwe-sleeve. Leyo bead ye-glue ephumayo iyisibonakaliso sokuthi uphawu lwakho selukhona. Vumela ijoyinti liphole lingaphazanyiswa ngaphambi kokuligoqa.
Gwema ilangabi elivulekile. Ukushisa okuningi kakhulu endaweni ethile kuyayishisa ithubhu futhi kungavimbela inhlaka ukuthi ingagelezi kahle, kuyilapho okuncane kakhulu kushiya i-solder ingancibiliki futhi isivalo singaphelele. Isibhamu sokushisa esilawulekayo siyithuluzi elifanele.
Ukukhetha isixhumi esifanele somsebenzi
Qondanisa isixhumi nosayizi womqhubi; amabhande ombala ezixhumini zesivalo se-solder abonisa ububanzi bezintambo zazo, ngakho-ke sebenzisa ibhande elifanelana negeyiji yakho. Ukuze uthole ukucwiliswa okuqhubekayo noma ukufutha njalo, beka phambili imikhiqizo enesilinganiso sesivalo esichazwe ngokucacile kanye nolwelwesi olunamathelayo olukhulu. Ukuze uthole umsebenzi wezimoto ongaphansi kwe-hood, funa isilinganiso sokushisa esifanelana nokushisa kwenjini. Futhi uthenge kumhlinzeki ochaza izinto zokwakha, ngoba ikhwalithi yesivalo kanye nesivalo inquma ukuthi isivalo sihlala isikhathi esingakanani ngempela.
Ukuxhumanisa okugcina isikhathi eside
Isixhumi esingangeni manzi ngempela senza imisebenzi emibili ngesikhathi esisodwa: senza isibopho sikagesi esizwakalayo futhi sivala umqhubi ngokumelene nomswakama nge-glue egeleza lapho ishiswa. Izixhumi zokunciphisa ukushisa ezifakwe i-solder seal kanye ne-glue ezifakwe i-glue zifeza lokhu uma uzihlanganisa nentambo, uzifudumeze ngokulinganayo, bese uqinisekisa ubuhlalu obunamathelayo ekugcineni ngakunye. Yenza lezo zinyathelo zifanele futhi izixhumi zakho zasolwandle, zezimoto, nezangaphandle zizokhipha amanzi nosawoti obhubhisa izixhumi ezivamile. Uma udinga izixhumi ezingangeni manzi kanye nemikhiqizo yokunciphisa ukushisa ehambisana nosayizi we-conductor yakho nendawo ezungezile, sithumelele imininingwane yesicelo sakho futhi sizoncoma ububanzi nobukhulu obufanele.
