Yini Eyenza Isixhumi Simelane Nokushisa?
Izixhumi ezivikelwe ezimelana nokushisa okuphezulu zenzelwe izinto ezingamelana nokushisa okuphezulu kunezixhumi ezivamile. Izingxenye zensimbi zivame ukwenziwa nge-alloys zethusi, zethusi, noma ezifakwe ithini, ezigcina ugesi uqhutshwa ngaphansi kokucindezeleka kokushisa okuphezulu. Izingxenye zokuvimbela zenziwe ngama-polymer akhethekile njenge-nylon, i-polytetrafluoroethylene (PTFE), noma i-silicone, ekwazi ukumelana nokuncibilika, ukuguquka, kanye nokuwohloka emazingeni okushisa aphezulu. Lokhu kuhlanganiswa kuqinisekisa ukuqhubeka kukagesi kanye nokuzinza kwemishini ngaphansi kwezimo ezahlukahlukene.
Yiziphi izinzuzo zokusebenzisa izixhumi ezivikela ukushisa ezivikela ukushisa?
1. Ukuphepha Okuthuthukisiwe Nokuvimbela Umlilo: Lena inzuzo eyinhloko. Ukushisa okumelana nokushisa, okuvame ukwenziwa ngezinto ezifana ne-silicone, i-fiberglass, noma ama-polymer akhethekile axhumene, kungamelana namazinga okushisa aphezulu ngaphandle kokuncibilika, ukonakala, noma ukubamba umlilo. Lokhu kuqukethe ama-arc kagesi noma ama-short circuits ngaphakathi kwesixhumi, okuvimbela ekushiseni izinto ezizungezile.
2. Ukuthembeka Okuphezulu Ezindaweni Ezinokushisa Okuphezulu: Ezinhlelweni ezifana nezindawo zezinjini zezimoto, imishini yezimboni, izintambo zangaphakathi zemishini, kanye nezibani, amazinga okushisa angakhuphuka. Ukushisa okujwayelekile (njenge-PVC) kungancibilika, kuqhekeke, futhi kuqhekeke, kuveze ama-conductor aphilayo. Amelana nokushisa.Izixhumi ze-T balondoloze ubuqotho babo, baqinisekise ukuxhumana okuqhubekayo nokuphephile futhi bavimbele ukwehluleka okungalindelekile.
3. Ukuvikelwa Emithonjeni Yokushisa Yangaphandle: Izixhumi zivame ukuhanjiswa eduze kwezingxenye ezishisayo njenge-exhaust manifolds, ama-boiler, noma ama-oven. Ukushisa okumelana nokushisa kusebenza njengesivikelo esivikelayo, kuvimbela ukushisa kwangaphandle ukuthi kulimaze i-terminal yensimbi yangaphakathi kanye ne-wire crimp, okungase kuholele ekukhuleni kokumelana kanye nokwehluleka okungenzeka.
4. Ukuvimbela i-Insulation Shrinkback: Uma zishiswa, ezinye izinto zokuvikela zingancipha zisuka esigungwini sensimbi, ziveze ucingo olungenalutho. Izinto ezingamelana nokushisa zenzelwe ngqo ukumelana nalokhu, zigcine ukumbozwa okugcwele futhi zivimbele ama-short circuits angengozi.
5. Ukuqina Okuthuthukisiwe Kwemishini: Izinto ezisetshenziselwa ukumelana nokushisa zivame ukuba nokuguquguquka okuhle kakhulu kanye nokumelana namakhemikhali, uwoyela, kanye nokuhuzuka. Lokhu kwenza indawo yokuxhuma iyonke ibe namandla kakhulu, ikwazi ukumelana nezimo ezinzima ngale kokushisa okuphezulu, njengasezinhlelweni zezimboni noma zezimoto.
