Tooj Tooj Liab Yeeb Nkab Xaiv Tp2 Tsheb Liab, Tooj Liab Cov Ntsiab Lus Ntawm 99.97% (Ntau dua cov nyhuv tooj liab, qhov zoo dua cov nyhuv tooj liab,. Tuam Tshoj engine engineation cov qauv "tsim dej txau cov neeg kho tshuab tooj liab engineering) 1. {4 4}}. 1 Vim tias xim liab tooj liab tsis muaj hlau hnyav, nws ua tau raws li tus qauv kev noj qab haus huv. Nws yog tus cwj pwm los ntawm kev ua tau ruaj khov, siab zog thiab cov coefficient ntawm thermal expansion. Yog li, dab tsi yuav tsum tau them nyiaj rau hauv lub vuam ntawm tooj liab yeeb nkab?
Vuam qog
Cov yam ntxwv:
Cov khoom siv brazing ntws tawm sab nraum lub npoo ntawm cov leeg thiab cov ntaub ntawv tsub zuj zuj.
Tsim kom muaj:
1, ntau dhau vuam ua hauj lwm siv hluav taws xob;
2, cov khoom siv brazing yog thov ntau dhau los yog thov hauv txoj kev tsis raug;
3, Weld Seam tsis nyob hauv tib theem thaum vuam;
Kev tiv thaiv kev ntsuas:
1, viav vias lub tshuab tso rau tom qab thaum muaj cua sov kom tiv thaiv kev kub ntxhov hauv lub zos;
2, Ntxiv cov ham rau xaub raws Weld los ntawm sab nraum qab ntawm txoj haujlwm cua sov;
3, Weldments tau npaj siab heev.
Tom ntug
Cov yam ntxwv:
Tus ntug ntawm Weld yog hlawv los ntawm cov nplaim taws mus rau hauv cov duab rotting, tab sis tsis tag kiag li hlawv los ntawm, thiab phab ntsa yeeb nkab nws tus kheej hlawv.
Tsim kom muaj:
1, vuam thermal efficievic yog loj heev;
2, txoj kev cua kub yog tsis ncaj ncees lawm.
Kev tiv thaiv kev ntsuas:
1, siv cov nplaim taws rau nruab nrab hlawv vuam.
2, Nplaim Swing rov qab thiab rov qab vuam tsau, zam cov cua sov hauv nruab nrab.
Overcooking lossis corrosion
Cov yam ntxwv:
Kev sib koom ua ke oxides tom qab vuam chunks tawm ntawm cov pob qij txha tom qab so kom huv si, muaj cov pob dub inlaid hauv kev sib koom ua ke.
Tsim kom muaj:
1, vuam thermal efficiency yog ntau heev (kub dhau lawm);
2, lub sijhawm vuam ntev heev.
3, Kev siv ntawm oxidizing nplaim taws vuam.
4, rov qab vuam (filler vuam)
Kev tiv thaiv kev ntsuas:
1, nruab nrab nruab nrab nplaim taws vuam;
2, tsis txhob rov ua dua vuam. Lub tsheb ciav hlau
Cov yam ntxwv:
Weld muaj impurities, uas ua rau tob tob ntawm weld nto.
Tsim kom muaj:
1, cov khoom siv brazing lossis cov khoom siv hauv paus nws tus kheej muaj roj, impurities lossis oxide zaj duab xis.
2, qhov ntsuas kub ntawm Weld yog siab dhau, ua rau lub phosphorus hauv cov khoom brazing rau kev loj hlob.
3, Lub cua kub ceev nrawm nrawm dhau.
Kev tiv thaiv kev ntsuas:
1, xyuas kom qhov huv huv ntawm brazing cov khoom thiab cov khoom siv hauv paus;
2, VUAM RAWS ZOO yog qhov tsim nyog, kom cov roj yaj cov pas dej siab molten ntau yog zoo tso tawm thaum weld solidifies
Porosity
Cov yam ntxwv:
Cov cua sov tsis txaus, cov roj hauv cov kua tsev poj niam hu ua kua hlau tsis ua tiav kom nchuav tag nrho, ua qhov ntawm qhov chaw lossis sab hauv.
Tsim kom muaj:
1, cov khoom siv fiber ntau lossis cov khoom siv hauv paus nws tus kheej muaj roj lossis oxidation;
2, lub vuam ceev nrawm heev, thiab roj hauv lub vuam tsis zoo tawm;
3, cov nplaim hluav taws yog nplaim taws, ua rau txo cov qhov cub hydrogen qhov;
Kev tiv thaiv kev ntsuas:
1, kom ntseeg tau tias niam txiv cov khoom siv fiber ntau;
2, Xaiv nruab nrab nplaim taws vuam, qog nrawm.
