Yintoni Eyenza Isixhumi Sentambo Singangeni Manzi Ngokwenene Ekusetyenzisweni Ngolwandle Nakwizithuthi?

Nabani na oye walandela ingxaki eyenzeka rhoqo kwisikhephe okanye kwitreyila uyazi ukuba imbangela idla ngokuba yi-splice ebolileyo. Amanzi afumana indlela yawo yokunxibelelana, i-copper oxidizes, i-resistance iyanyuka, kwaye i-circuit iqala ukungasebenzi kakuhle. "Amanzi angangeni" aprintwa kwiipakethe ezininzi ze-connector, kodwa ayizizo zonke iimveliso eziyifumanayo. Nantsi into eyenza i-wire connector ingangeni manzi, kunye nendlela yokufumana i-seal ehlala iminyaka emininzi yokufuma, ityuwa, kunye nokungcangcazela.

Kutheni izihlanganisi eziqhelekileyo zingaphumeleli ngaphandle

Isixhumi esiqhelekileyo se-crimp senza i-joint eqinileyo yombane, kodwa ayenzi nto ukuthintela amanzi ukuba angangeni. Ukufuma kunamathela kwimicu ye-conductor ngesenzo se-capillary, kuhamba phantsi kwe-insulation ngaphaya kwe-slice ebonakalayo. Nje ukuba amanzi afikelele kwi-copper, i-corrosion iqala, kwaye kwindawo enetyuwa ikhawuleza kakhulu. Isiphumo siba yi-conductor eluhlaza, ebuthathaka kunye nonxibelelwano olungasebenzi kancinci ngokwaneleyo ukuba luphazamise ukuxilonga.

Yingakho ukufakelwa kwezixhobo zasemanzini, zeemoto, ezolimo, nezangaphandle zifuna izihlanganisi ezenzelwe ngokukodwa ukuvala i-slice, kungekhona nje ukuyidibanisa. Injongo sisithintelo esithintela amanzi ukuba angafiki kwi-conductor.

Indlela yokutywina kunye nobushushu be-solder Izihlanganisi ze-Shrink yenza uphawu

Isixhumi sesitywino sesolder sidibanisa imisebenzi emibini kwisingxobo esinye. Ngaphakathi kwityhubhu ekhanyayo yokunciphisa ubushushu kukho indandatho yesolder enobushushu obuphantsi, ejikelezwe yindandatho yeglue enyibilikayo. Uhluba uze ufake ii-conductors ezimbini ukuze zilingane ngaphakathi Indandatho yeSolder, uze ufake ubushushu. Izinto ezintathu zenzeka ngokulandelelana: ityhubhu iyancipha, iringi yesolder iyanyibilika ize ingene kwiintambo ukuze izibophe ngombane, kwaye iringi ze-adhesive ziyanyibilika kwaye zenze isitywino esingangeni manzi kwisiphelo ngasinye sesingxobo.

Loo nto yokuncamathelisa yinxalenye ebangela ukuvalwa kwamanzi. Xa i-hot-melt iphola, itshixa kwi-insulation yentambo kunye netyhubhu, ivale indlela amanzi ebeya kuhamba ngayo kwi-conductor. Isixhumi esicacileyo se-heat-shrink butt sisebenza ngendlela efanayo, sisebenzisa ityhubhu enamatheleyo ukuvala i-joint egobileyo nokuba ingenaso i-solder ring. Zombini ezi ndlela zinomgaqo ofanayo: dibanisa i-bond yombane ethembekileyo kunye ne-glue moisture barrier.

Ukuqonda iireyithingi ze-IP

Xa isixhumi sithi sisebenza kakuhle emanzini, khangela umlinganiselo we-IP (Ingress Protection) endaweni yegama ngokwalo. Umlinganiselo unamanani amabini. Elokuqala ligubungela izinto eziqinileyo kunye nothuli; elesibini ligubungela amanzi. Kwizixhumi zentambo, idijithi yamanzi yeyona nto ibalulekileyo. Umlinganiselo ojikeleze i-IP67 uthetha ukuba uqhagamshelo oluvaliweyo lunokumelana nokuntywiliselwa okwethutyana emanzini phantsi kweemeko ezichaziweyo, nto leyo efanela uninzi lwezihlunu zasemanzini nezeemoto. Umlinganiselo ophezulu ubonisa ukumelana nokuvezwa kwamanzi ngamandla.

Phatha iireyithingi ze-IP njengesikhokelo esithatha ukufakelwa ngokuchanekileyo. Isixhumi esikwaziyo ukutywina okuphezulu sisavuza ukuba sishushubezwa ngokungalinganiyo, ukuba iglu ayikaze iphume ngokupheleleyo, okanye ukuba ucingo alulingani kakuhle kwisingxobo. Uvavanyo luchaza amandla emveliso; ubuchule bakho bugqiba ukuba uyafikelela na kuyo.

Ukufaka izihlanganisi ezingangeni manzi ngokuchanekileyo

Isitywino sixhomekeke ngokupheleleyo ekufudumaleni okufanelekileyo, ngoko ke eli nyathelo livuza unonophelo oluncinci. Hlukanisa umqhubi ngamnye ukuya kubude obuchaziweyo kwisixhumi, uze ujike iziphelo ezixineneyo ukuze kungabikho micu ilahlekayo. Faka zombini izixhumi ukuze zidibane ngaphakathi kwe-solder ephakathi okanye kwindawo ye-crimp. Kwisixhumi se-heat shrink esifana ne-crimp, crimp kuqala, uze emva koko ufudumale.

Faka ubushushu ngokulinganayo ngesixhobo sobushushu, ujikeleze umkhono endaweni yokujolisa kwindawo enye. Jonga imiqondiso ebonakalayo: umbhobho utsalela phantsi kakuhle kwintambo, iringi yesolder iyanyibilika kwaye ingene kwiintambo ukuze umkhono ube nembonakalo efanayo yesinyithi, kwaye kuvela intsimbi encinci yeglue kumacala omabini omkhono. Loo ntsimbi yeglue iphuma luphawu lokuba isitywino sakho senziwe. Vumela umkhono uphole ungaphazanyiswa ngaphambi kokuba uwuthambise.

Kuphephe ilangatye elivulekileyo. Ubushushu obuninzi kakhulu butshisa ityhubhu kwaye bunokuthintela iglu ukuba ingahambi kakuhle, ngelixa incinci kakhulu ishiya i-solder inganyibiliki kwaye itywina lingagqitywanga. Isibhamu sobushushu esilawulekayo sisixhobo esifanelekileyo.

Ukukhetha isiqhagamsheli esifanelekileyo somsebenzi

Tshatisa isixhumi nobukhulu bomqhubi; imiphetho yombala kwizixhumi zesitywini se-solder ibonisa uluhlu lwazo lweengcingo, ngoko sebenzisa ibhendi ehambelana negeyiji yakho. Ukuze ucwilise ngokuqhubekayo okanye utshize rhoqo, beka phambili iimveliso ezinereyithingi yesitywini echazwe ngokucacileyo kunye ne-glue lining enkulu. Kumsebenzi wemoto ongaphantsi kwe-hood, khangela umlinganiselo wobushushu ohambelana nobushushu be-injini. Kwaye uthenge kumthengisi ochaza izixhobo, kuba umgangatho wesincamathelisi kunye ne-solder umisela ukuba isitywini sihlala ixesha elingakanani ngokwenene.

Uqhagamshelo lokutywina oluhlala ixesha elide

Isixhumi esingangeni manzi ngokwenene senza imisebenzi emibini ngaxeshanye: senza ikhonkco lombane elivakalayo kwaye sivala umqhubi nxamnye nokufuma ngeglue ehamba xa ishushu. Izixhumi zeglue ezitywiniweyo kunye nezincamathelisi ezinamathelayo ziyakwenza oku xa uzidibanisa nocingo, uzifudumeze ngokulinganayo, kwaye uqinisekise i-glue enamathelayo kwicala ngalinye. Yenza loo manyathelo ngokuchanekileyo kwaye iziqwenga zakho zasemanzini, zemoto, nezangaphandle ziya kuzisusa amanzi kunye netyuwa etshabalalisa izixhumi eziqhelekileyo. Ukuba ufuna izixhumi ezingangeni manzi kunye neemveliso ezinciphisa ubushushu ezihambelana nobukhulu bomqhubi wakho kunye nokusingqongileyo, sithumelele iinkcukacha zakho zesicelo kwaye siya kucebisa uluhlu kunye nobukhulu obufanelekileyo.
