Yog tias lub saw saws tsis tau teeb tsa kom raug, cov xwm txheej yuav tshwm sim thaum siv (xws li
rov qab ua nruj ua tsiv), los yog thov ua tib zoo nyeem cov cuab yeej thiab pom daim ntawv qhia ua ntej siv.
Cov kev ceev faj yog raws li hauv qab no:
Thaum txhim kho cov saw hniav, ua tib zoo saib xyuas cov kev taw qhia ntawm kev sib hloov.Cov saws loj thiab me me tig mus rau hauv cov kev taw qhia tsis sib xws (nyob ntawm qhov kev xav ntawm cov hniav).
Thaum txhim kho lub saw hniav, ua tib zoo saib xyuas lub saw ncej, so hmoov av thiab pom
hmoov av ntawm lub saw ncej, kom tsis txhob qaij thaum lub sijhawm ua haujlwm.
Lub flange thiab kho cov txiv ntseej yuav tsum nruj ua ntej ua haujlwm.Yog tias muaj xwm txheej tso cai,
concentricity ntawm cov saw hniav tig tuaj yeem ntsuas tau siv tus dial ntsuas tom qab
kev teeb tsa.
Tej teeb meem thiab cov kev daws teeb meem:
① tawg tawm ntawm qhov txiav ntug ntawm lub rooj tsavxwm: lub saw hniav yog npub lossis muaj qhov sib txawv,
thiab nws yuav tsum tau hloov nrog tus tshiab.
② tawg rau ntawm ib sab ntawm qhov txiav ntug hauv qab ntawm lub rooj tsavxwm: lub ntsiab pom thiab pab pom
tsis nyob hauv txoj kab ncaj nraim, kho qhov pom axis sab laug thiab sab xis.
③ tawg tawm ntug ntawm ob sab ntawm cov txiav ntug hauv qab lub rooj tsavxwm: ob sab yog
tawg, thiab qhov dav ntawm qhov zawj txiav los ntawm cov cim pom tsis txaus. Kho
lub saw ncej nce thiab nqis rau txiav.
④ Kev ntxhib los mos: Cov saw hniav yog npub los yog muaj cov ntiv taw hauv cov hniav, uas yuav tsum yog
hloov los yog xa mus rau kev sib tsoo.
⑤ Pom cov hniav nrog cov hniav lwj lossis ploj lawm: lawv tuaj yeem xa tuaj rau kev sib tsoo thiab kho,
thiab tuaj yeem rov siv dua tom qab qib, txuag cov nqi.
