Qib kev ua tau zoo 4.8
Cov lugs ntawm qib no siv tau rau kev sib sau ua ke cov rooj tog niaj hnub, kho cov khoom sab hauv ntawm cov khoom siv hauv tsev, cov qauv sib dua, thiab kev kho ib ntus nrog cov kev xav tau qis zog.
Qib kev ua tau zoo 8.8
Cov qib no ntawm cov bolts tuaj yeem siv rau cov khoom siv hauv tsheb, kev sib txuas tseem ceeb ntawm cov khoom siv kho tshuab dav dav, thiab kev tsim cov qauv hlau; nws yog qib muaj zog tshaj plaws, siv rau kev sib txuas tseem ceeb uas yuav tsum tau tiv taus cov khoom loj lossis kev cuam tshuam.
Qib kev ua tau zoo 10.9
Cov qib no ntawm cov bolts tuaj yeem siv rau hauv cov tshuab hnyav (xws li cov excavators), cov qauv hlau choj, kev sib txuas khoom siv siab, thiab cov qauv hlau tseem ceeb hauv tsev; lawv tuaj yeem dais cov khoom hnyav thiab kev co hnyav, thiab muaj cov kev xav tau siab heev rau kev ntseeg tau thiab kev tiv taus qaug zog.
Qib kev ua tau zoo 12.9
Cov qib ntawm cov bolts no tuaj yeem siv rau hauv cov qauv aerospace, cov tshuab precision siab, thiab cov khoom sib tw cav; rau cov xwm txheej hnyav uas qhov hnyav thiab ntim yog qhov tseem ceeb thiab qhov twg lub zog kawg yog qhov xav tau.
Cov hlau tsis xeb A2-70/A4-70
Cov qib no ntawm cov bolts tuaj yeem siv rau hauv cov tshuab ua zaub mov, cov khoom siv tshuaj lom neeg cov kav dej flanges, cov chaw sab nraum zoov, cov khoom siv nkoj; cov chaw ua haujlwm corrosive xws li cov av noo, cov kua qaub-base media lossis cov xwm txheej xav tau kev tu cev huv siab.
Kev ntsuas cov khoom siv kho tshuab xws li lub zog thiab qhov nyuaj ntawm cov bolts yog qhov tseem ceeb tshaj plaws rau kev xaiv.
Nws yog sawv cev los ntawm cov lej lossis cov lej ua ke nrog cov ntawv, xws li 4.8, 8.8, 10.9, A2-70.
Cov ntsia hlau: Cov cim yog nyob rau hauv daim ntawv ntawm XY (piv txwv li 8.8)
X (thawj ntu ntawm tus lej):Sawv cev rau 1/100 ntawm lub zog tensile nominal (Rm), hauv cov chav ntawm MPa. Piv txwv li, 8 sawv cev rau Rm ≈ 8 × 100 = 800 MPa.
Y (qhov thib ob ntawm tus lej):Sawv cev rau 10 npaug ntawm qhov sib piv ntawm lub zog tawm los (Re) rau lub zog tensile (Rm).
