Imvamisa emaphakathiimishini yokushisela amabalazidinga ama-electrode ukuqedela inqubo yokushisela. Izinga lama-electrode lithinta ngqo ikhwalithi yama-welds. Ama-Electrode asetshenziswa kakhulu ukudlulisa amandla amanje kanye nengcindezi kucezu lokusebenza. Kodwa-ke, ukusebenzisa izinto ezisezingeni eliphansi ze-electrode kungasheshisa ukuguga ngesikhathi sokusetshenziswa, okuholela ekwandeni kwesikhathi sokugaya kanye nokumoshakala kwezinto ezingavuthiwe. Ngakho-ke, kubalulekile ukukhetha ama-electrode ngokusekelwe ezintweni ezishiselwe.
Ama-electrode adinga ukuba nezinga elithile lobulukhuni bezinga lokushisa eliphezulu, ikakhulukazi ukugcina lobu bunzima emazingeni okushisa aphakathi kuka-5000-6000°C. Ubulukhuni obuphezulu bezinga lokushisa eliphezulu buvimbela ukunqwabelana kwe-electrode ngesikhathi senqubo yokushisela. Ngokuvamile, izinga lokushisa endaweni yokuxhumana phakathi kwendawo yokusebenza kanye ne-electrode ngesikhathi sokushisela cishe liyingxenye yephoyinti lokuncibilika lensimbi eshiselwe. Uma impahla ye-electrode inobunzima obuphezulu emazingeni okushisa aphezulu kodwa ubulukhuni obuphansi ngesikhathi sokushisela, ukupakisha kusengenzeka.
Ukuphela kokusebenza kwe-electrode kuza ngezindlela ezintathu: i-cylindrical, i-conical, ne-spherical. Izimo eziyisiyingi neziyindilinga zisetshenziswa kakhulu ngoba zithuthukisa ukupholisa futhi zinciphisa izinga lokushisa lama-electrode. Nakuba ama-electrode ayindilinga anesikhathi eside sokuphila, ukushabalaliswa kokushisa okusheshayo, nokubukeka okungcono kwe-weld, ukukhiqiza kanye nokuwalungisa ikakhulukazi kungaba inselele. Ngakho-ke, ama-electrode e-conical ngokuvamile ayathandwa.
Ukukhethwa kwendawo yokusebenza kuncike ekucindezelweni okusetshenzisiwe. Kudingeka indawo enkulu yokusebenza lapho ingcindezi iphezulu ukuvimbela ukulimala ekugcineni kwe-electrode. Ngakho-ke, njengoba ubukhulu bepuleti bukhula, ububanzi bomsebenzi osebenzayo budinga ukwanda. Indawo yokusebenza kancane kancane iguga futhi iyanda ngesikhathi sokusebenza. Ngakho-ke, ukulungiswa okufika ngesikhathi kuyadingeka ngesikhathi sokukhiqizwa kokushisela ukuvimbela ukwehla kokuminyana kwamanje okuholela ekunciphiseni ukungena kwe-fusion noma ngisho kungabikho i-fusion nucleus. Ukwamukela indlela lapho i-current ikhula ngokuzenzakalelayo ngokunyuka kwenani lama-welds kungandisa isikhathi phakathi kokulungiswa okubili.
Ungawaxazulula Kanjani Amaphutha Amancane Emishinini Yokushisela Imvamisa Emaphakathi?
Imishini ayisebenzi amandla: ukungavamile emshinini we-thyristor, iphutha ebhokisini lokulawula P ibhodi.
Izinto ezisetshenziswayo azisebenzi ngemva kokusebenza: ukucindezela kwegesi okunganele, ukuntuleka komoya ocindezelwe, i-valve ye-solenoid engavamile, ukushintsha kokusebenza okungavamile, noma isilawuli esingavulwanga amandla, ukusebenza kokudluliswa kwezinga lokushisa.
Imifantu ivela kuma-welds: ungqimba lwe-oxidation ngokweqile endaweni yokusebenza, umshini wokushisela ophezulu, ingcindezi ye-electrode ephansi, amaphutha ensimbi eshiselwe, ukungahambi kahle kwe-electrode ephansi, ukulungiswa kwemishini okungalungile.
Amandla anganele wamaphoyinti e-weld: ukucindezela okunganele kwe-electrode, noma ngabe induku ye-electrode ivikelwe ngokuqinile.
Ukuchafaza ngokweqile ngesikhathi sokushisela: i-oxidation eqinile yekhanda le-electrode, ukuthintana kabi kwezingxenye ezishiselwe, noma ngabe inkinobho yokulungisa isethwe phezulu kakhulu.
Umsindo omkhulu ovela ku-welding AC contactor: kungakhathaliseki ukuthi i-voltage engenayo ye-contactor ye-AC ngesikhathi sokushisela iphansi kune-voltage yayo yokukhululwa ngama-volts angu-300.
Izisetshenziswa zishisa ngokweqile: hlola ingcindezi yokungena kwamanzi, izinga lokugeleza kwamanzi, izinga lokushisa lamanzi, noma ngabe ukupholisa kwamanzi kuvinjiwe: leo@agerawelder.com
