Hauv kev lag luam loj heev ntawm kev tsim kho tshuab thiab tshuab kev lag luam, qee yam khoom feem ntau tsis quav ntsej txawm tias ua lub luag haujlwm tseem ceeb. Cov saw hlau yog ib tus phab ej uas tsis tau paub zoo. Cov kev sib dhos yooj yim no ntawm cov txuas thiab cov menyuam sib txuas yog lub hauv paus uas ntau lub tshuab thiab cov khoom siv ua haujlwm. Txij li tsheb kauj vab mus rau cov siv conveyor, los ntawm cov khoom siv ua liaj ua teb mus rau lub cav tsheb,cov saw hlauyog qhov tseem ceeb heev. Cov blog no tshawb nrhiav txog qhov tseem ceeb ntawm cov saw hlau, tshawb nrhiav lawv keeb kwm, kev tsim qauv, kev siv thiab kev cia siab yav tom ntej.
Ib zaj keeb kwm luv luv ntawm cov saw hlau
Lub tswv yim ntawm cov saw hlau dov tau pib txij li xyoo pua 19th. Thawj cov saw hlau dov uas siv tau tau tsim los ntawm Hans Renold hauv xyoo 1880. Renold tus qauv tsim yog qhov hloov pauv loj heev vim nws muab txoj hauv kev txhim khu kev qha thiab ua haujlwm tau zoo ntawm kev xa cov zog kho tshuab. Ua ntej muaj cov saw hlau dov, cov tshuab siv cov txheej txheem tsis zoo xws li siv txoj siv sia thiab cov hlua, uas yooj yim plam thiab hnav.
Renold cov saw hlau muaj cov menyuam cylindrical txuas ua ke los ntawm cov saw hlau sab. Tus qauv tsim no txo qhov kev sib txhuam thiab kev hnav, ua rau muaj kev hloov pauv fais fab du thiab zoo dua. Tus qauv tsim yooj yim ntawm cov saw hlau tseem tsis tau hloov pauv ntau xyoo dhau los, ua pov thawj rau lawv qhov ua tau zoo thiab kev ntseeg siab.
Anatomy ntawm cov saw hlau
Yuav kom nkag siab txog qhov tseem ceeb ntawm cov saw hlau, ib tug yuav tsum paub txog lawv cov qauv yooj yim. Cov saw hlau feem ntau muaj cov khoom hauv qab no:
- Cov menyuam: Ib qho khoom cylindrical uas tig ib ncig ntawm tus pin kom txo qhov kev sib txhuam ntawm cov saw thiab lub sprocket.
- Tus Pin: Tus pas nrig cylindrical txuas cov phaj sab hauv thiab sab nraud, cia lub roller tig tau ywj pheej.
- Phaj Sab Hauv: Lub phaj hlau tiaj tiaj uas tuav cov menyuam thiab cov koob rau hauv qhov chaw.
- Phaj Sab Nraud: Zoo ib yam li phaj sab hauv, tab sis nyob rau sab nraud ntawm cov saw, muab lub zog thiab kev ruaj khov ntxiv.
- Bush: Ib qho khoom cylindrical ntsia nruab nrab ntawm tus pin thiab roller kom txo qhov kev sib txhuam thiab kev hnav.
Kev sib xyaw ua ke ntawm cov khoom no tsim cov saw hlau uas yoog tau tab sis muaj zog uas xa hluav taws xob tau zoo thiab ntseeg tau.
