Cov saw hlau uas siv rau ntau yam tshuab tau ntau pua xyoo lawm. Lawv txoj kev hloov pauv los ntawm kev siv ib txwm mus rau kev siv niaj hnub no yog ib qho pov thawj rau lawv txoj kev siv tau zoo thiab kev hloov pauv tau ntev. Chiv thawj tsim los rau cov haujlwm yooj yim xws li rub thiab tsa, cov saw hlau uas siv rau ntau yam tshuab tau hloov pauv los ua lub luag haujlwm tseem ceeb hauv cov tshuab nyuaj thiab siab heev thoob plaws ntau yam lag luam.
Cov saw hlau uas siv rau cov log tsheb kauj vab tau pib siv txij li xyoo pua 19th, thaum lawv feem ntau siv rau cov tsheb kauj vab thiab cov tshuab ua haujlwm thaum ntxov. Tus qauv tsim ntawm cov saw hlau uas siv rau cov log tsheb kauj vab muaj cov txuas thiab cov log sib txuas, uas muab ib txoj hauv kev txhim khu kev qha ntawm kev xa lub zog thiab kev txav mus los. Raws li lub sijhawm dhau los, thaum kev lag luam thiab kev nce qib ntawm thev naus laus zis tau nce qib, qhov kev thov rau cov saw hlau uas muaj zog dua thiab ua haujlwm tau zoo dua tau txuas ntxiv mus. Qhov no tau ua rau muaj kev tsim cov ntaub ntawv muaj zog dua thiab kev txhim kho hauv cov txheej txheem tsim khoom, uas tso cai rau cov saw hlau uas siv rau hauv cov ntawv thov uas xav tau ntau dua.
Cov kev siv ib txwm rau cov saw hlau muaj xws li kev xa hluav taws xob hauv cov tshuab, cov khoom siv thauj khoom thiab cov khoom siv ua liaj ua teb. Lawv lub peev xwm los hloov hluav taws xob los ntawm ib lub ncej mus rau lwm qhov ua rau lawv tsis tseem ceeb hauv ntau yam txheej txheem kev lag luam. Txawm li cas los xij, thaum thev naus laus zis txuas ntxiv mus, cov saw hlau tau pom cov ntawv thov tshiab thiab tshiab hauv kev lag luam niaj hnub no.
Hauv kev lag luam tsheb, cov saw hlau siv rau hauv kev tsav tsheb kom ntseeg tau tias muaj kev sib dhos ua ke ntawm lub cav camshaft thiab crankshaft. Lub luag haujlwm tseem ceeb no cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ua haujlwm ntawm lub cav sib xyaw sab hauv. Qhov ruaj khov thiab kev ntseeg tau ntawm cov saw hlau ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov tseeb thiab kev sib xws yog qhov tseem ceeb.
Kev tsim cov saw hlau dov kuj tau pom lawv siv hauv kev lag luam aerospace thiab kev tiv thaiv. Hauv cov dav hlau thiab cov khoom siv tub rog, cov saw hlau dov yog siv rau hauv cov txheej txheem uas xav tau lub zog siab, qhov hnyav tsawg, thiab kev tiv thaiv rau cov xwm txheej hnyav. Cov saw hlau dov yog ib qho tseem ceeb hauv cov ntawv thov tseem ceeb no vim lawv muaj peev xwm ua haujlwm hauv qhov chaw nyuaj thiab tiv taus cov khoom hnyav.
Tsis tas li ntawd xwb, cov saw hlau tau pom lawv txoj kev mus rau hauv kev lag luam khoom noj khoom haus uas qhov kev huv thiab kev huv yog qhov tseem ceeb. Cov khoom siv ua zaub mov siv cov saw hlau stainless hlau tshwj xeeb uas tsim los kom ntseeg tau tias kev ua haujlwm du thiab huv. Lawv txoj kev tiv thaiv corrosion thiab lub peev xwm tiv taus kev ntxuav ntau zaus ua rau lawv zoo tagnrho rau kev tswj hwm cov qauv kev huv huv hauv cov chaw tsim khoom noj.
Qhov kev siv tau ntau yam ntawm cov saw hlau kuj pom tseeb hauv kev lag luam hluav taws xob rov ua dua tshiab. Hauv cov tshuab cua turbine, cov saw hlau siv los hloov lub zog tig ntawm cov hniav mus rau lub tshuab hluav taws xob, qhov chaw uas nws hloov mus ua lub zog hluav taws xob. Lub zog tensile siab thiab kev tiv taus qaug zog ntawm cov saw hlau ua rau lawv zoo tagnrho rau kev tiv taus kev ua haujlwm tas mus li thiab kev ua haujlwm hnyav ntawm cov tshuab cua turbine.
Hauv kev tsim khoom niaj hnub no, cov saw hlau ua lub luag haujlwm tseem ceeb hauv kev siv neeg hlau thiab kev ua haujlwm tsis siv neeg. Lawv yog cov khoom tseem ceeb hauv cov tshuab conveyor, cov kab sib dhos thiab cov khoom siv tuav cov khoom siv, pab txav cov khoom thiab cov khoom lag luam kom du thiab zoo. Qhov tseeb thiab kev ntseeg tau ntawm cov saw hlau pab cov txheej txheem tsis siv neeg khiav tsis muaj teeb meem, ua rau muaj kev tsim khoom ntau ntxiv thiab txo lub sijhawm tsis ua haujlwm.
Kev tsim cov saw hlau kuj tau cuam tshuam los ntawm kev nce qib hauv cov ntaub ntawv thiab cov thev naus laus zis lubrication. Kev siv cov alloys siab heev thiab kev kho qhov chaw ua rau lub zog thiab kev tiv thaiv kev hnav ntawm cov saw hlau, ua rau nws lub neej kev pabcuam ntev dua thiab kev ntseeg tau. Tsis tas li ntawd, kev tsim cov roj nplua nyeem tshwj xeeb ua rau kev ua tau zoo ntawm cov saw hlau hauv kev siv ceev thiab kub siab, thiab ua rau lawv muaj txiaj ntsig zoo dua hauv cov chaw lag luam niaj hnub no.
Thaum kev lag luam txuas ntxiv mus thiab qhov xav tau ntawm cov tshuab ua haujlwm siab dua, cov saw hlau yuav txuas ntxiv hloov kho thiab nrhiav cov ntawv thov tshiab. Lub keeb kwm ntev ntawm cov saw hlau, los ntawm nws keeb kwm qis hauv cov ntawv thov ib txwm mus rau nws lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no, yog ib qho pov thawj rau nws qhov tseem ceeb thiab kev ua tau zoo. Raws li cov ntaub ntawv, cov thev naus laus zis tsim khoom thiab kev coj ua engineering txuas ntxiv mus, cov saw hlau yuav tseem yog lub hauv paus ntawm kev xa hluav taws xob thiab kev tswj hwm kev txav mus los rau ntau xyoo tom ntej.
