Ultrasonic hlau txuas

Ntsiab Cai ntawm Vuam

Ultrasonic hlau vuam siv cov kev co ua haujlwm siab ua kom muaj lub zog xa mus rau ob chav hlau kom tau txais welded. Nyob rau hauv qhov siab ceev, ob txheej hlau yog rub tawm mus rau lwm tus los tsim lub fusion ntawm txheej txheej molecular

Kev vuam

(1) Kev co thiab txhuam kev sib tsoo: thawj txheej txheem ntawm ultrasonic hlau vuam feem ntau yog qhov kev sib txhuam, thiab nws qhov kev sib txhuam ntawm kev sib txhuam ceev zoo ib yam li qhov sib txhuam ntawm qhov sib txhuam, tab sis qhov nrawm tsuas yog kaum tawm microns. Lub luag haujlwm tseem ceeb ntawm cov txheej txheem no yog tshem tawm cov impurities xws li roj thiab oxides nyob rau sab nraud ntawm lub weldment, kom lub ntsej muag muaj hlau ntshiab.

(2) Kub nce mus rau theem: Hauv cov txheej txheem txuas ntxiv ultrasonic rov qab ua rau muaj kev sib txhuam, qhov kub ntawm qhov chaw sib chwv nce (qhov kub ntawm qhov chaw vuam yog li ntawm 35% mus rau 50% ntawm qhov chaw melting ntawm cov hlau), qhov cuam tshuam deformation poob, thiab lub zog zoo li qub thiab elastic tshuab kev co Nyob rau hauv cov yeeb yaj kiab sib xyaw ua ke ntawm kev sib koom ua ke kev ntxhov siab, cov yas ntws ntawm qhov chaw sib txuas ntawm qhov txuas txuas txuas ntxiv, yog li ntawd cov yeeb yaj kiab tawg oxide tseem ua rau tawg thiab txawm nkag mus rau hauv cov khoom siv welded, thiab cov atoms ntawm lub ntshiab hlau nto yog infinitely ze rau atomic zog. Tsis pub dhau ntawm qhov muaj feem ntawm kev sib tsoo, atoms diffuse thiab sib xyaw ua ke, sib sau ua cov kua siv lead ua siv los yog kev rov ua dua tshiab.

(3) Cov theem sib khi ua ntu zus: Nrog kev nce qib ntawm cov txheej txheem kev sib txhuam, qhov chaw hu rau qhov chaw me me tau loj dua thiab loj dua, thiab cov yas deformation ntawm qhov sib tiv tauj kuj nce zuj zus. Lub eddy tam sim no yas ntws txheej txawm yog tsim hauv qhov chaw vuam, thiab cov neeg kho tshuab ntawm qhov txuas tau tshwm. Tom

Adaiv

1)Cov khoom siv vuam tsis yaj, thiab cov hlau tsis tawg yooj yim.

2) Nws tuaj yeem paub txog lub vuam ntawm tib hom, tsiaj sib txawv, hlau thiab tsis yog hlau.

3) Tsis muaj cua sov, siv zog hluav taws xob, tsim nyog rau vuam siab thermal conductivity, conductive hlau xws li tooj liab thiab txhuas.

4) Qhov kev coj ua yog qhov zoo tom qab vuam, thiab lub resistivity tsawg kawg los sis yuav luag tsis tau.

5) Cov uas yuav tsum tau muaj tsawg dua ntawm cov vuam hlau nto, ob leeg xeb thiab xaim hluav taws xob tuaj yeem txuas nrog.

6) Sev luv luv lub sijhawm, tsis muaj flux, roj lossis solder.

7) Vuam yam tsis muaj qhov txhuam, kev tiv thaiv ib puag ncig thiab kev nyab xeeb.
