Cov saw hlau yog cov khoom tseem ceeb hauv ntau yam lag luam xws li tshuab, tsheb thiab kev ua liaj ua teb. Cov saw hlau no tau tsim los kom xa cov zog kho tshuab tau zoo, ua rau lawv yog ib feem tseem ceeb ntawm ntau yam kev siv. Txawm li cas los xij, kev xaiv qhov loj me ntawm cov saw hlau feem ntau tuaj yeem yog ib txoj haujlwm nyuaj, tshwj xeeb tshaj yog rau cov neeg tshiab rau hauv daim teb no. Phau ntawv qhia no lub hom phiaj yog kom piav qhia txog cov txheej txheem thiab ua kom yooj yim dua rau cov neeg siv txiav txim siab qhov loj me ntawm cov saw hlau zoo tshaj plaws rau lawv cov kev xav tau tshwj xeeb.
Kawm txog qhov loj ntawm cov saw hlau:
Ua ntej peb yuav kawm txog qhov nyuaj ntawm kev xaiv qhov loj ntawm cov saw hlau uas raug, cia peb kawm txog lub kaw lus uas siv los qhia nws qhov loj. Cov saw hlau muaj nws lub suab, uas sawv cev rau qhov deb ntawm nruab nrab ntawm ob lub koob txuas uas nyob ib sab. Lub suab yog qhia ua nti lossis metric units (piv txwv li, 0.375 nti lossis 9.525 millimeters).
Kauj Ruam 1: Txheeb xyuas koj cov kev xav tau:
Yuav kom txiav txim siab tau qhov loj ntawm cov saw hlau uas tsim nyog, nws yog ib qho tseem ceeb heev uas yuav tsum soj ntsuam qhov yuav tsum tau ua ntawm ib daim ntawv thov tshwj xeeb. Xav txog cov hauv qab no:
1. Kev Xa Hluav Taws Xob: Kwv yees qhov xav tau hluav taws xob ntawm lub kaw lus hauv cov units ntawm horsepower (HP) lossis kilowatts (kW). Txheeb xyuas qhov tso zis hluav taws xob siab tshaj plaws thiab txhua qhov xwm txheej uas muaj peev xwm ua haujlwm ntau dhau.
2. Ceev: Txheeb xyuas qhov ceev tig (RPM) ntawm lub sprocket tsav thiab lub sprocket tsav. Xav txog qhov ceev ua haujlwm xav tau thiab txhua qhov kev hloov pauv ceev.
3. Tej yam ib puag ncig: Xav txog tej yam kev ua haujlwm xws li kub, av noo, plua plav, lossis lwm yam tshuaj lom uas yuav muaj.
Kauj Ruam 2: Xam qhov ntev ntawm cov saw hlau:
Thaum txiav txim siab txog qhov yuav tsum tau ua, kauj ruam tom ntej yog xam qhov ntev ntawm cov saw hlau. Qhov no yog txiav txim siab los ntawm qhov deb ntawm qhov chaw nruab nrab ntawm lub sprocket tsav thiab lub sprocket tsav. Siv cov mis hauv qab no:
Qhov ntev ntawm saw (suab) = (tus naj npawb ntawm cov hniav ntawm lub sprocket tsav + tus naj npawb ntawm cov hniav ntawm lub sprocket tsav) / 2 + (qhov deb nruab nrab / suab)
Kauj Ruam 3: Xav Txog Cov Kev Xav Tau Txog Kev Nyuaj Siab:
Kev nruj kom zoo yog qhov tseem ceeb rau lub neej thiab kev ua haujlwm ntawm cov saw hlau. Kev nruj tsis txaus tuaj yeem ua rau cov saw hlau plam, ua rau hnav ua ntej thiab txo qis kev sib kis hluav taws xob. Ntawm qhov tod tes, kev nruj ntau dhau tuaj yeem ua rau cov saw hlau nruj, ua rau muaj kev sib txhuam ntau ntxiv thiab muaj peev xwm tawg. Saib cov lus qhia ntawm cov chaw tsim khoom kom paub qhov ntau thiab tsawg ntawm kev nruj kom haum rau koj cov saw hlau qhov loj me thiab kev siv.
Kauj Ruam 4: Xyuas kom tseeb tias lub peev xwm thauj khoom muaj peev xwm:
Lub peev xwm thauj khoom ntawm cov saw hlau yog txiav txim siab los ntawm nws qhov loj me. Nws yog ib qho tseem ceeb kom paub tseeb tias cov saw hlau xaiv tau muaj peev xwm tuav tau qhov hnyav uas xav tau. Cov chaw tsim khoom feem ntau muab cov duab qhia txog lub peev xwm thauj khoom uas suav nrog ntau yam xws li lub zog tensile, txoj kab uas hla ntawm cov saw hlau thiab cov khoom siv. Xaiv cov saw hlau uas tshaj qhov yuav tsum tau thauj khoom ntawm koj daim ntawv thov kom ntseeg tau tias muaj lub neej ntev thiab kev ntseeg tau.
Kev txiav txim qhov loj ntawm cov saw hlau yog ib qho tseem ceeb heev rau kev ua haujlwm zoo ntawm cov kab ke xa hluav taws xob. Kev txiav txim qhov loj ntawm cov saw hlau kom raug tuaj yeem txiav txim siab tau zoo los ntawm kev soj ntsuam lub zog, qhov ceev, qhov chaw ib puag ncig thiab qhov yuav tsum tau ua kom nruj. Nco ntsoov sab laj nrog cov lus qhia ntawm cov chaw tsim khoom thiab cov ntawv qhia txog lub peev xwm thauj khoom kom ntseeg tau tias koj lub cev siv tau ntev thiab ntseeg tau. Nrog kev nkag siab zoo txog cov txheej txheem txiav txim qhov loj, koj tuaj yeem xaiv cov saw hlau zoo tshaj plaws rau koj daim ntawv thov, uas yuav pab kom muaj kev ua haujlwm zoo tshaj plaws thiab kev ua tau zoo.
