Imigqa yokushisela ivame kakhulu phakathi kwamaphutha amaningiumjovo olubunjiwe imikhiqizo.Ngaphandle kwezingxenye ezimbalwa ezibunjwe ngomjovo ezinobumo bejometri olula kakhulu, imigqa yokushisela ivela ezingxenyeni eziningi ezibunjwe ngomjovo (imvamisa isesimweni somugqa noma umsele omise okwe-V), ikakhulukazi emikhiqizweni emikhulu neyinkimbinkimbi edinga ukusetshenziswa kwesikhunta samasango amaningi. kanye nokufaka.
Umugqa we-weld awuthinti nje kuphela ikhwalithi yokubukeka yezingxenye zepulasitiki, kodwa futhi uthinta izakhiwo zemishini yezingxenye zepulasitiki, njengamandla omthelela, amandla aqinile, ukuphakama ngesikhathi sekhefu, njll. Ngaphezu kwalokho, umugqa we-weld nawo unomthelela omkhulu ukwakhiwa komkhiqizo kanye nempilo yezingxenye zepulasitiki.Ngakho-ke, kufanele kugwenywe noma kuthuthukiswe ngangokunokwenzeka.
Izimbangela eziyinhloko zomugqa we-weld yilezi: lapho ipulasitiki encibilikisiwe ihlangana nokufakwa, imbobo, indawo enezinga lokugeleza elingapheli noma indawo enesiphazamiso esiphazamisekile sokugeleza kwezinto zokugcwalisa emgodini wesikhunta, ukuncibilika okuningi kuyahlangana;Lapho ukugcwaliswa komjovo wesango kwenzeka, izinto azikwazi ukuhlanganiswa ngokugcwele.
(1) Izinga lokushisa eliphansi kakhulu
Izakhiwo zokushunqisa nokuguquguquka kwezinga lokushisa eliphansi lezinto ezincibilikisiwe azilungile, futhi imigqa yokushisela kulula ukwakha.Uma izindawo zangaphakathi nezangaphandle zezingxenye zepulasitiki zinemigqa emihle yokushisela endaweni efanayo, kuvame ukubangelwa ukushisela okungalungile okubangelwa ukushisa okuphansi kwezinto ezibonakalayo.Mayelana nalokhu, izinga lokushisa lomgqomo kanye ne-nozzle lingakhuliswa ngokufanelekile noma umjikelezo womjovo unganwetshwa ukwandisa izinga lokushisa lempahla.Ngesikhathi esifanayo, inani lamanzi okupholisa adlula esikhunjini kufanele lilawulwe, futhi izinga lokushisa lesikhunta kufanele lenyuke ngokufanele.
(2)Isikhuntaamaphutha
Imingcele yesakhiwo sesistimu ye-mold gating inethonya elikhulu ekuhlanganiseni kwe-flux, ngoba ukuhlanganiswa okungalungile kubangelwa ikakhulukazi i-shunt kanye nokuhlangana kwe-flux.Ngakho-ke, uhlobo lwesango olunokuphambukisa okuncane luzokwamukelwa ngangokunokwenzeka futhi indawo yesango izokhethwa ngokunengqondo ukuze kugwenywe izinga lokugcwalisa elingahambisani kanye nokuphazamiseka kokugeleza kwezinto zokugcwalisa.Uma kunokwenzeka, isango elilodwa lephoyinti kufanele likhethwe, ngoba leli sango alikhiqizi imifudlana eminingi yokugeleza kwezinto ezibonakalayo, futhi izinto ezincibilikisiwe ngeke zihlangane kusuka ezinkomba ezimbili, ngakho-ke kulula ukugwema imigqa ye-weld.
(3) Ukukhipha isikhunta esibi
Lapho umugqa wokuhlanganisa wento encibilikisiwe uqondana nomugqa wokuvala isikhunta noma i-caulking, umoya oqhutshwa imifudlana eminingi yezinto ezibonakalayo emgodini wesikhunta ungakhishwa esikhaleni sokuvala isikhunta noma i-caulking;Kodwa-ke, lapho umugqa we-welding ungahambelani nomugqa wokuvala isikhunta noma i-caulking, futhi imbobo ye-vent ingasethiwe kahle, umoya osele emgodini wesikhunta oqhutshwa yizinto zokugeleza awukwazi ukukhishwa.I-bubble iphoqeleka ngaphansi kwengcindezi ephezulu, futhi ivolumu iyancipha kancane kancane, futhi ekugcineni icindezelwe ibe iphuzu.Ngenxa yokuthi amandla ashukumisayo amangqamuzana omoya ocindezelwe aguqulwa abe amandla okushisa ngaphansi kwengcindezi ephezulu, izinga lokushisa endaweni okuqoqa kuyo izinto ezincibilikisiwe liyenyuka.Uma izinga lokushisa layo lilingana noma liphakeme kancane kunezinga lokushisa lokubola lempahla eluhlaza, amachashazi Aphuzi azovela endaweni encibilikayo.Uma izinga lokushisa liphakeme kakhulu kunezinga lokushisa lokubola kwezinto zokusetshenziswa, amachashazi amnyama azovela endaweni encibilikayo.
(4) Ukusetshenziswa okungalungile kwe-ejenti yokukhulula
I-ejenti yokukhulula kakhulu noma uhlobo olungalungile luzobangela imigqa yokushisela ebusweni bezingxenye zepulasitiki.Ekubumbeni umjovo, inani elincane le-ejenti yokukhulula ngokuvamile lisetshenziswa ngokulinganayo kuphela ezingxenyeni okungelula ukuzidiliza, njengezintambo.Ngokomthetho, inani le-ejenti yokukhululwa kufanele lincishiswe ngangokunokwenzeka.
