Phau ntawv qhia no piav qhia txog qhov extrusion eccentricity yog dab tsi, vim li cas nws tseem ceeb, yuav ua li cas kho nws ntawm cov tsoos tuag, thiab qhov chaw ruaj khov -center thiab self-centering tooling haum rau hauv. Yog tias koj xav tau kev nthuav dav ntawm cov ncauj lus, peb kuj tseem npog nws hauv pebOptical fiber ntau eccentricity hloov phau ntawv qhia.
Dab tsi yog Eccentricity hauv Cable Extrusion?
Eccentricity yog qhov offset ntawm qhov nruab nrab ntawm tus neeg xyuas pib (los yog cable core) thiab qhov nruab nrab ntawm txheej extruded nyob ib ncig ntawm nws. Nyob rau hauv ib tug zoo kawg nkaus concentric cable, phab ntsa thickness yog tib yam tag nrho txoj kev nyob ib ncig ntawm lub circumference. Thaum cov tub ntxhais zaum tawm - nruab nrab hauv qhov tuag, ib sab ntawm phab ntsa yog nyias thiab sab nraud yog tuab dua.
Eccentricity feem ntau yog qhia raws li qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus phab ntsa thickness, los yog raws li feem pua ntawm cov phab ntsa nominal. Nyob rau hauv lub khw hauv pem teb, cov neeg ua haujlwm xyuas nws los ntawm kev txiav ib lub nplhaib qauv ntawm lub tshuab extruded, txiav nws kom huv si, thiab ntsuas cov phab ntsa ntawm ob peb lub ntsiab lus nyob ib ncig ntawm lub voj voog (feem ntau sab saum toj, hauv qab, sab laug, thiab sab xis) nrog lub ntsuas qhov ntsuas, lub qhov projector, lossis lub thickness gauge. International xeem txoj kev xws li covIEC 60811 series ntsuas tag nrho qhov ntev thiab tsis yog -hlau phab ntsa thicknesspiav qhia yuav ua li cas cov kev ntsuas no yuav tsum tau ua kom cov txiaj ntsig sib piv ntawm cov neeg ua haujlwm thiab cov chaw sim.
Vim li cas Eccentricity Control Matters
Qhov chaw tsis zoo tsis yog qhov teeb meem ntawm kev pleev xim xwb. Nws muaj qhov tshwm sim uas tshwm sim hauv kev ua haujlwm, nqi, thiab kev lees txais cov neeg siv khoom:
