Xaiv Cov Dej Dej Yeeb Nkab Sib Txuas ntawm Phosphor Bronze Yeeb Nkab
(1) Xov txuas. Qhov no yog daim ntawv lees paub zoo rau cov kav dej me me, thiab muaj qhov zoo uas lwm cov ntawv sib txuas tsis tuaj yeem sib piv. Xws li lub qhov taub me me. Yuav luag tag nrho cov khoom siv dej siv siv xov txuas; cov yeeb nkab fittings yog tus qauv. Siab sib xws; lub zog thiab airtightness ntawm kev sib txuas yog ob qho tib si. Txawm li cas los xij, cov xov tooj cua phosphor tooj liab yuav tsum muaj cov phab ntsa tuab dua, thiab tus nqi yog ib txwm siab dua, uas yuav zam tsis tau qhov cuam tshuam rau kev nrov npe ntawm phosphor tooj liab yeeb nkab hauv cov tsev pej xeem.
(2) Brazing thiab qhov txuas txuas. Cov txheej txheem yog qhov nyuaj dua, xav tau qhov tseeb siab, kev sib txuas lub zog thiab kev nyab xeeb. Cov yam ntxwv ntawm daim ntawv sib txuas no yog tias lub raj tooj liab phosphor tuaj yeem ua cov phab ntsa nyias, kom cov nqi tsev qis dua. Yog li ntawd, raws li cov qauv kev nyob tam sim no, nws muaj tus nqi txhawb nqa zoo hauv cov tsev pej xeem nyob.
(3) Clamp type mechanical extrusion txuas. Nws muaj kev ua haujlwm yooj yim. Nrog cov yam ntxwv ntawm kev tsim kho yooj yim, cov phab ntsa nyias nyias phosphor tooj liab kuj tseem tuaj yeem txuas nrog, thiab vim tias cov yeeb nkab fittings raug pov tseg tooj liab, tus nqi yog qhov pheej yig. Txawm li cas los xij, tib neeg qhov tseem ceeb ntawm kev teeb tsa kav dej yog qhov loj, thiab nws yog qhov tsim nyog rau kev teeb tsa saum npoo ntawm cov kav dej.
Txog kev txuas ntawm phosphor tooj liab yeeb nkab thiab fittings, peb qhov kev paub yog tias nws tuaj yeem khoov ncaj qha yam tsis muaj lub luj tshib txuas. Rau cov yeeb nkab kab hauv qab φ28mm, feem ntau ntawm lawv yog ib nrab-tawv phosphor tooj liab yeeb nkab. Nws yog ib qho yooj yim los siv txuam cov yeeb nkab khoov. Khoov rau hauv ≤900 ℃; tuaj yeem brazed (qhov kub siab tshaj 500 ℃) yam tsis muaj soldering (kub qis dua 450 ℃); solderable tuaj yeem siv tau yam tsis muaj daim npav. Kev sib txuas siab. Tsuas yog siv daim npav hauv qhov tsis xwm txheej. Crimping txoj kev. Cov ntaub ntawv sim qhia tias lub zog tensile ntawm brazed sib koom ua ke yog ob peb zaug uas ntawm phosphor tooj liab raj nws tus kheej. Daim npav. Lub zog tensile ntawm crimping txuas yog qis dua lub zog ntawm phosphor tooj liab raj nws tus kheej. Qhov kev sib txuas no raug rau qhov kub thiab txias ntev thiab ib puag ncig hloov pauv, thiab qhov teeb meem tsis zoo tuaj yeem tshwm sim.
