Cov saw hlau yog ib qho tseem ceeb hauv ntau yam kev siv tshuab. Lawv xa hluav taws xob thiab muab kev ywj pheej, kev ruaj khov thiab kev ua haujlwm zoo. Txhua txoj saw hlau yog tsim los kom tiv taus cov khoom thauj thiab cov xwm txheej tshwj xeeb, sib txawv ntawm qhov loj me, lub zog thiab kev ua haujlwm. Niaj hnub no, peb yuav tsom mus rau ob hom tshwj xeeb: 10B txoj saw hlau thiab 50 txoj saw hlau. Cia peb dhia mus rau hauv lub ntiaj teb zoo kawg nkaus ntawm cov saw hlau thiab nrhiav seb ob txoj saw hlau no puas zoo sib xws tiag.
Paub cov hauv paus:
Ua ntej yuav tham txog qhov sib piv, nws yog ib qho tseem ceeb kom nkag siab txog qee yam tseem ceeb ntawm cov saw hlau. "Roller chain" yog ib lo lus siv los txhais cov saw hlau uas txuas nrog cov hlau hu ua "links". Cov saw hlau no yog tsim los koom nrog cov sprockets kom xa lub zog thiab kev txav mus los ntawm ob qho chaw.
Qhov sib txawv ntawm qhov loj:
Qhov txawv tseem ceeb ntawm 10B thiab 50 cov saw hlau yog qhov loj. Tus lej ntawm cov saw hlau sawv cev rau nws qhov siab, uas yog qhov deb ntawm txhua tus pin. Piv txwv li, hauv 10B cov saw hlau, qhov siab yog 5/8 nti (15.875 mm), thaum nyob rau hauv 50 cov saw hlau, qhov siab yog 5/8 nti (15.875 mm) - zoo li tib qhov loj.
Kawm txog cov qauv loj ntawm saw hlau:
Txawm hais tias muaj qhov loj me sib xws, 10B thiab 50 cov saw hlau muaj cov qauv loj sib txawv. Cov saw hlau 10B ua raws li British Standard (BS) cov kev cai ntsuas qhov ntev, thaum 50 cov saw hlau ua raws li American National Standards Institute (ANSI) system. Yog li ntawd, cov saw hlau no sib txawv hauv kev ua haujlwm, qhov loj me thiab lub peev xwm thauj khoom.
Cov kev xav txog kev tsim kho:
Qhov sib txawv ntawm cov qauv kev tsim khoom tuaj yeem cuam tshuam rau lub zog thiab kev ua tau zoo ntawm cov saw hlau. ANSI cov saw hlau feem ntau muaj cov phaj loj dua, uas muab lub zog tensile siab dua thiab muaj peev xwm thauj khoom ntau dua. Piv rau, BS cov sib piv muaj kev kam rau siab dua ntawm kev tsim khoom, ua rau muaj kev ua tau zoo dua hauv kev tiv thaiv kev hnav, lub zog qaug zog thiab kev tiv thaiv kev cuam tshuam.
Qhov sib pauv tau:
Txawm hais tias cov saw hlau 10B thiab cov saw hlau 50 yuav muaj tib lub suab, lawv tsis tuaj yeem hloov pauv vim muaj qhov sib txawv ntawm qhov loj me. Kev sim hloov pauv yam tsis tau hais txog cov qauv tsim khoom tuaj yeem ua rau cov saw hlau puas ua ntej lub sijhawm, ua rau lub tshuab puas tsuaj thiab muaj kev phom sij rau kev nyab xeeb. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus qhia kom raug thaum xaiv cov saw hlau thiab sab laj nrog tus kws tshaj lij kom paub tseeb tias sib xws.
Cov kev xav txog kev siv tshwj xeeb:
Yuav kom paub tseeb tias txoj saw twg zoo rau ib qho kev siv, yuav tsum tau soj ntsuam cov yam xws li qhov hnyav, qhov ceev, tej yam ib puag ncig thiab lub neej ua haujlwm xav tau. Nws raug pom zoo kom saib cov phau ntawv qhia txog kev tsim kho, cov ntawv teev npe ntawm cov chaw tsim khoom lossis tiv tauj tus kws tshaj lij hauv kev lag luam.
Hauv kev xaus, thaum 10B cov saw hlau thiab 50 cov saw hlau tej zaum yuav zoo li muaj qhov ntsuas sib npaug ntawm 5/8 nti (15.875 hli), lawv yog cov qauv loj sib txawv. 10B saw hlau ua raws li British Standard (BS) qhov system sizing, thaum 50 cov saw hlau ua raws li American National Standards Institute (ANSI) system. Cov kev hloov pauv no hauv cov qauv tsim khoom ua rau muaj qhov sib txawv ntawm cov kev ntsuas qhov ntev, lub peev xwm thauj khoom thiab kev ua tau zoo tag nrho. Yog li ntawd, nws yog qhov tseem ceeb kom paub tseeb thiab siv cov saw hlau kom raug rau ib daim ntawv thov tshwj xeeb kom ntseeg tau tias muaj kev ua tau zoo thiab txhim khu kev qha.
Nco ntsoov tias cov saw hlau uas koj xaiv tuaj yeem cuam tshuam rau kev ua haujlwm thiab lub neej ntawm koj lub tshuab, yog li ua qhov kev txiav txim siab zoo thiab ua kom muaj kev nyab xeeb thiab kev ua tau zoo ua qhov tseem ceeb tshaj plaws.
