Cov roj casing yog luv luv sib koom ua ke, ua rau qhov tshwm sim no los ntawm kev ua haujlwm tsis zoo xws li cov menyuam lossis cov ncej eccentricity, lossis lub zog vuam ntau dhau, lossis lwm yam laj thawj. Raws li qhov vuam ceev nce, lub raj khoob extrusion ceev nce. Qhov no pab txhawb lub extrusion ntawm cov kua hlau txheej thiab oxides uas tau rhuab mus rau yaj mus rau lub zoo weld. Nyob rau tib lub sijhawm, nce qhov vuam ceev kuj tseem tuaj yeem txo lub sijhawm cua sov ntawm qhov zawj ntawm qhov chaw, kom lub voj voog luv luv ntawm cov roj tuaj yeem ua kom luv luv thiab cov tshav kub cuam tshuam tuaj yeem nqaim.

Ntawm qhov tsis sib xws, tsis tsuas yog lub tshav kub cuam tshuam rau thaj tsam dav, tab sis kuj yog txheej nyias ntawm cov kua hlau tseem ceeb ua rau ntawm qhov zawj nto ua tuab, thiab cov burrs loj yog tsim, uas ua rau qhov zoo ntawm cov vuam. Txawm li cas los xij, ntawm qee qhov tso zis hluav taws xob, qhov txias vuam ceev tsis tuaj yeem nce ntxiv yam tsis muaj kev txwv. Txwv tsis pub, cov cua sov ntawm ob sab ntawm lub qhov cub yuav tsis ncav cuag qhov kub ntawm qhov vuam, kom muaj qhov tsis xws luag lossis tsis muaj vuam txhua.

Rau cov hlau tsis muaj steel, qhov luv luv sib txuas ripple coefficient ntawm cov roj cuam tshuam rau kev tsim cov welds. Capacitance filtering txo cov ripple kom tsawg dua 1%. Thaum vuam stainless hlau, qhov zaus feem ntau yog 200 welds nrog zoo toughness thiab siab zaus tshav kub cuam tshuam cheeb tsam. . Feem ntau, cov phab ntsa sab hauv thiab sab nrauv ntawm cov yeeb nkab welded yog txau rov qab los ntawm qhov chaw vuam. Nruab nrab, nruam foams yog qhov zoo ntawm kev tawm tswv yim tias lub vuam fais fab yog txaus thiab cov neeg kho tshuab tsis sib xws thiab cov npuas dej tsaus welding tsis sib xws thiab cov vuam tsis zoo.
