Thaum nws los txog rau kev xa hluav taws xob, cov saw hlau yog cov khoom tseem ceeb thiab ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab ua haujlwm tau zoo ntawm ntau yam kev siv hauv kev lag luam. Hauv cov blog no, peb yuav saib ze dua rau kev ua haujlwm sab hauv ntawmcov saw hlau, lawv txoj haujlwm, thiab lawv qhov tseem ceeb hauv kev ua haujlwm ntawm ntau yam tshuab sib txawv.
Lub saw hlau yog dab tsi?
Cov saw hlau uas siv rau dov yog cov saw hlau uas muaj cov menyuam hlau luv luv uas txuas ua ke los ntawm cov saw hlau sab. Cov menyuam hlau no nyob nruab nrab ntawm cov phaj sab hauv thiab sab nraud, tsim kom muaj lub zog thiab txhim khu kev qha rau kev xa hluav taws xob los ntawm ib lub ncej mus rau lwm qhov. Cov saw hlau uas siv rau dov yog siv dav hauv cov tsheb kauj vab, tsheb kauj vab, cov tshuab xa khoom thiab cov tshuab siv hauv kev lag luam vim lawv ruaj khov thiab muaj zog tensile siab.
Lub saw hlau ua haujlwm li cas?
Kev siv cov saw hlau yog qhov yooj yim tab sis ua haujlwm tau zoo heev. Thaum ntsia rau hauv lub tshuab, cov saw hlau raug tsav los ntawm lub sprocket, uas yog lub iav uas sib txuas nrog cov saw hlau cov menyuam. Thaum lub sprocket tig, nws rub cov saw hlau cov menyuam, ua rau lawv txav mus los thiab xa lub zog mus rau lub ncej lossis lub tshuab txuas nrog. Qhov kev txav mus los tas mus li no hloov lub zog los ntawm cov khoom tsav mus rau cov khoom tsav, ua rau lub tshuab ua haujlwm tau raws li nws lub hom phiaj.
Cov saw hlau uas siv rau cov khoom hnyav thiab ua haujlwm tau ntawm ntau qhov ceev sib txawv, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev xa hluav taws xob txhim khu kev qha. Tsis tas li ntawd xwb, cov saw hlau uas siv rau cov khoom hnyav tuaj yeem hloov kho kom haum rau cov kev xav tau tshwj xeeb, xws li cov qhov ntev dua lossis cov khoom siv rau kev thauj cov khoom hnyav tshwj xeeb, ua rau lawv muaj peev xwm hloov pauv tau yooj yim thiab siv tau zoo hauv cov chaw ua haujlwm.
Kev saib xyuas cov saw hlau
Ib yam li lwm yam khoom siv kho tshuab, cov saw hlau yuav tsum tau saib xyuas tas li kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws thiab siv tau ntev. Kev siv roj nplua nyeem kom zoo yog qhov tseem ceeb los txo qhov kev sib txhuam thiab kev hnav ntawm cov rollers thiab sprockets, yog li tiv thaiv kev ua tsis tiav ua ntej thiab txuas lub neej ntawm cov saw hlau. Tsis tas li ntawd, kev tshuaj xyuas tas li rau cov cim ntawm kev ncab, xeb, lossis kev puas tsuaj rau lub nruas yog qhov tseem ceeb rau kev txheeb xyuas cov teeb meem uas yuav tshwm sim thiab daws lawv ua ntej lawv nce mus rau qee yam loj dua.
Yuav kom koj cov saw hlau ua haujlwm tau zoo, peb xav kom koj ua raws li cov lus qhia ntawm lub sijhawm ua kom lubrication ntawm cov chaw tsim khoom thiab siv cov roj nplua nyeem zoo uas tsim tshwj xeeb rau cov saw hlau. Tsis tas li ntawd xwb, kev ua kom koj cov saw hlau huv si thiab tsis muaj cov kuab paug yuav pab txhim kho kev ntseeg siab thiab kev ua haujlwm zoo ntawm nws.
Qhov tseem ceeb ntawm cov saw hlau hauv tshuab
Cov saw hlau ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo thiab txhim khu kev qha ntawm ntau yam tshuab, pab txhawb rau kev ua haujlwm ntawm cov khoom siv thiab tshuab hauv ntau yam lag luam. Lawv lub peev xwm xa hluav taws xob tau zoo, tiv taus cov khoom hnyav, thiab ua haujlwm hauv ntau yam xwm txheej ib puag ncig ua rau lawv tsis tseem ceeb hauv cov ntawv thov uas xav tau kev xa hluav taws xob txhim khu kev qha.
Hauv kev lag luam tsheb, cov saw hlau siv rau hauv cov cav kom tsav cov camshafts, kom ntseeg tau tias lub cav lub qhov nqus thiab lub qhov tso pa tawm raug lub sijhawm. Lub luag haujlwm tseem ceeb no cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub tsheb thiab kev siv roj tsawg, qhia txog qhov tseem ceeb ntawm cov saw hlau hauv kev siv tsheb.
Tsis tas li ntawd xwb, cov saw hlau siv dav hauv cov tshuab conveyor rau kev tsiv cov khoom hauv cov chaw tsim khoom, cov chaw faib khoom, thiab cov tsev rau khoom. Lawv txoj kev tsim kho ruaj khov thiab kev ua haujlwm du ua rau lawv ua tau raws li qhov xav tau ntawm kev tuav cov khoom siv tas mus li, pab txhawb rau kev ntws cov khoom tsis muaj teeb meem hauv ntau yam kev lag luam.
Hauv kev ua liaj ua teb, cov saw hlau yog ib feem tseem ceeb ntawm kev ua haujlwm ntawm cov khoom siv ua liaj ua teb xws li tsheb laij teb, tshuab sib xyaw thiab tshuab sau qoob loo. Cov saw hlau no yog lub luag haujlwm rau kev xa lub zog los ntawm lub cav mus rau cov khoom tseem ceeb xws li lub log, lub tshuab tsav tsheb thiab cov txheej txheem sau qoob loo, uas ua rau cov neeg ua liaj ua teb ua tiav cov haujlwm tau zoo thiab ua kom muaj txiaj ntsig zoo tshaj plaws hauv daim teb.
Tsis tas li ntawd xwb, cov saw hlau feem ntau pom muaj nyob rau hauv cov khoom siv hauv kev tsim kho, cov tshuab mining thiab cov txheej txheem kev lag luam, qhov twg kev xa hluav taws xob txhim khu kev qha yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov khoom siv hnyav thiab cov txheej txheem.
