Kanjani nokuthi yiziphi electrodes ezizokhetha ukuthungela inverter? Ukubuka konke, izici, izinhlobo nokubuyekeza

Ukwehliswa manje kuyinkinga edingekayo kokubili emisebenzini yamakhosi ochwepheshe kanye nochwepheshe bezindlu. Ngesizo salo, ungalungisa imikhiqizo yensimbi, futhi uma kunesidingo, yakha amasha. Ukuze uqiniseke ukuthi ikhwalithi yezinyawo zihloniphekile, udinga isipiliyoni esincane nomshini wokushisa. Akuyona indima encane edlalwa ngamathengi akhethiwe kahle.

Ngakho-ke, abaningi abafake ama-novice bafake isithakazelo embuzweni wokuthi yiziphi i-electrodes ezizokhetha ukuthungela inverter. Thatha le nqubo ngokuziphendulela. Iseluleko sabaphathi abanolwazi luzosiza ukuqonda umehluko phakathi kwezinto ezihanjisiwe bese ukhetha okukhethwa kukho okungcono kunoma yiluphi uhlobo lomsebenzi.

Izimpawu zokuthungela inverter

Ngaphambi kokukhetha ama-electrodes for welding inverter, kubalulekile ukuzijwayeza ngezici zalolu hlelo. Kuhilela ukusebenzisa imishini ekhethekile. Umshini wokushisa umshini wokushisa, osebenzisa indlela yokuqhaqhazela i-arc welding.

Izinzuzo zale nqubo uma kuqhathaniswa nezinhlobo ze-transformer seziye zaziswa isikhathi eside ngabaphathi bezobuchwepheshe. Abaphenduli manje basebenzise kaningi kunezinye izinhlobo zemishini. Lokhu kubangelwa ukushisa kwabo okwamanje. Ngakho-ke kuphenduka isikhathi eside kakhulu futhi siphezulu kakhulu.

I-unit inverter, enezinsiza zokuvuselela, iyakwazi ukukhiqiza i-voltage njalo neyashintshayo ekusebenzeni amandla. Uma kungekho izihlungi zamaminithi, kuphela umthamo oqhubekayo okhishwayo. Lesi sici kufanele sicatshangelwe uma senza umsebenzi.

Umdwebo wokudonsa

Uma usebenzisa umshini wokusebenza emisebenzini yayo, kubalulekile ukuthi ufunde ngehlelo layo lokusebenza. Izinto ezisetshenziswayo ezinkulu kulezi zixhobo ziyi-electrodes. Zenziwe ngendlela yenduku yensimbi, lapho ikhona manje isondela endaweni yokusebenza. Ukufunda ukuthi yiziphi i-electrocodes ezingcono kumishini yokudonsa i- inverter , kubalulekile ukungena ngokujulile ohlelweni lokusebenza kwemishini kanye nenqubo.

Uma usebenzisa i-inverter, amanye amathuluzi nawo asetshenziswa. Lezi zihlanganisa uhlelo lokulawula, isihlungi samaminithi (noma isilungiselelo), i-transformer, kanye ne-converter yemvamisa. Lokhu kuvumela ukuthi idivayisi isebenze ngezinto ezihlukahlukene. Ngisho nesibonelo esifanayo salesi sitshalo sikhombisa ukusebenzisa ama-electrode amamaki ahlukile uma uhambisa izinto ezahlukene. Ngakho-ke, ukhetho lwabo kufanele lunikezwe ukunakwa okukhethekile.

Essence of electrodes

Uma ufunda umbuzo wokuthi yimaphi ama-electrode okumele ukhethe ukudonsa nge-inverter, kufanele uzijwayele ngedivayisi yalesi sici esisebenzisekayo. Njengoba sekushiwo ngenhla, imodeli efanayo yedivayisi isetshenziswa ezimweni ezahlukene. Ngakho-ke, ama-electrode kufanele akhethwe ngokusho kwenqubo yokusebenza.

Ukukhiqizwa kwansuku zonke kwengxenye enkulu yemikhiqizo yayo ngendlela yokuthengwa kwe- inverter ye- arc welding manual . Leli thuluzi lenziwe ngentambo yensimbi. Le nduku iphathwa ngokugqoka okukhethekile ngokucindezela. Yenzelwe ukuqinisekisa ukuqina komlilo, kanye nokuvikela ukugeza okufakwe emanzini emiphumeleni yomoya emoyeni. Izinto zokukhiqiza kwemikhiqizo enjalo zisetshenziswa ngokuhluke kakhulu. Izindinganiso zokukhiqiza ze-electrode zilawulwa yi-GOST 2246, evunyelwe ngo-1970.

Izinhlobo

Lapho unquma ukuthi yiziphi futhi ama electrode okumele ukhethe ukudonsa nge-inverter, kubalulekile ukubhekisela ku-GOST engenhla. Ithi kunezinhlobo ezintathu zemithengethe ezifanelekayo emisebenzini enjalo. Ama-electrode angaba ne-carbonaceous, alloyed ne-doped kakhulu. Zenziwe ngezinhlobo ezahlukene zocingo.

Umsunguli ozokhiqiza ukukhwelisa kwe-inverter ekhaya, akudingeki ukuba angene ezinhlobonhlobo ezinjalo. Kumele kuqashelwe ukuthi wonke ama-electrode ahlukaniswe ngamaqembu amabili amakhulu. Isigaba sokuqala sihlanganisa izinto ezenzelwe izakhiwo ezithintekayo, nasesigaba sesibili sokwejwayelekile.

Uma ukushisa kungabandakanyeki ekwakheni izakhiwo zensimbi ezithwala imithwalo, okuzocindezelwa okukhulu, ngakho-ke izinhlobo ezilula zemikhiqizo kufanele zikhethwe. Uma usebenzisa i-inverter ngezidingo zezomnotho, lokhu kuzoba ngokwanele.

Ucwaningo lwama-electrode asekhaya

Abanikazi bezobuchwepheshe balungele ukwabelana nakho kwabo futhi bakutshele ukuthi yimaphi ama-electrodes angcono kumshini we-welding. Ukubuka konke izinhlobo ezithandwayo kuzovumela umuntu omusha ukuba akhethe imikhiqizo efanele. Kuze kube yimanje, ama-electrode athandwa kakhulu kuma-inverters asetshenziselwa izimo zasekhaya yi-ANO, MR-3. Ngezici zabo kufanele zixoxwe ngokuningiliziwe.

Uhlobo lokuqala lwe-electrodes alubangeli izinkinga ngesikhathi sokusebenza. Bashaywa kalula ngaphandle kokudinga ukuqala kokubala. Kumeluleki we-novice, i-ANS yindlela engcono kakhulu. I-MP-3 ibhekwa njengento engathengwa yonke indawo. Ivumela ukudonsa ngisho nasezindaweni ezinogwaja, ezihlambulukile, kanye nasezimo ezimanzi.

Sibutsetelo sama-electrodes aphezulu

Uma ufunda ukuthi yimaphi ama-electrode okumele ukhethe ukuhambisa nge-inverter, kubalulekile ukukhetha imikhiqizo enjengeM MR-3C, kanye no-SSSI-13/55 ngezinhlobo ezinokwethenjelwa zezakhiwo. Zihlukaniswa njengeqembu lezidakamizwa ezisetshenziselwa ukwakha izakhiwo ezithintekayo.

Njengoba izidingo ezikhudlwana zekhwalithi yesikhwama esiphelile, kungcono ukunikeza ukhetho kumkhiqizo MR-3C. Ama-electrode anjalo asetshenziselwa ukucubungulwa kwensimbi nge-current constant, alternating current of reverse polarity.

Imisebenzi ebaluleke kakhulu lapho ukhiqiza izakhiwo ezithwala imithwalo kufanele ukhethe amakhasimende angama-brand SSSI. Kodwa-ke, inkosi eyodwa kuphela engasebenza nabo. Ngomuntu oqalayo, uhlamvu olungenakuqhathaniswa lwalo electrode ngeke lube ngamazinyo. Kodwa, njengoba ufunde ukuphatha i-SSSI, kungenzeka ukuthi udale izingqimba ezihlala isikhathi eside ngokuqina okukhulu (ngisho nasezimo eziphansi zokushisa).

Izinhlobonhlobo zensimbi

Lapho ufunda ukuthi yimaphi ama-electrode okumele ukhethe ukuthungela inverter, udinga ukunaka uhlobo lwezinto zokusebenza. Ngensimbi ngayinye izinguqulo zabo zokwehliswa kwe-welding zenzelwe.

Ngensimbi ye-cast, okumele kwenziwe kunikwe ama-electrodes ohlobo lwe-OZCH-2. Ukukhiqizwa kwabo kulawulwa yiGOST 9466 kusukela ngo-1975. Uma kudingekile ukuthi usebenze nge- low-carbon steel, kungcono ukuthenga imikhiqizo ye-ANO-4 nge-layer ye-rutile phezulu noma i-ANO-6, ene-ilmenite yokugqoka.

Ama-carbon steels avamile adinga ukusebenzisa ama-electrodes OZS-4, MR-3S, MP-3, UONI13 / 45, ANO-21, njll. Amakhamera angenalutho futhi aphezulu afuna ukusetshenziswa kwamathengi okukhishwa kwe-inverter ngaphansi kwe-brand TsL-11.

Indlela yokukhetha i-electrode

Ngemva kokucabangela ukuthi kungcono ukukhetha ama-electrodes for welding inverter, kufanelekile ukukhuluma amagama ambalwa mayelana nezici zokuthenga kwabo. Okokuqala, kubalulekile ukunaka ukwakheka kwesimbozo esetshenziswa kumkhiqizo. Lolu lwazi lungatholakala kumilayezo yokusetshenziswa. Lokhu kuzokuvumela ukuba ukhethe uhlobo olufanele ngokusho kohlobo lwezinto ezibonakalayo.

Ngokuqhubekayo kumadokhumenti ahambisanayo kubalulekile ukucubungula ukulingana kwe-deposit. Kuye ngokulingana komsebenzi, kanye namanani okugeleza, inombolo edingekayo yama-electrode itholakala.

Futhi, ungathengi imikhiqizo engenazo izitifiketi ezifanele zekhwalithi. Lokhu kungaba okungaphephile. Ikhwalithi yamajoyina uma usebenzisa izinto ezihlukumezayo ingahluka kakhulu emphumela oyifunayo. Ngakho-ke, inqubo yokuzikhethela nokuthenga kufanele ithathwe ngokuziphendulela.

Ngemva kokucubungula ukuthi yimaphi ama-electrode okumele akhethe ukukhipha nge-inverter, ngisho nomphathi we-novice uzokwazi ukuthola izinhlobo ezifanele. Umsebenzi uzodlula ngokushesha futhi ngokuphepha. Umphumela uyoba omuhle ngisho nangokuqala.
