Ua kom tiav cov lus qhia rau SAWMILLS
Ntoo yog ib qho tseem ceeb ntawm peb lub neej. Ntoo txhawb peb lub tsev thiab lub ru tsev saum peb lub taub hau. Peb noj ntawm cov rooj ntoo, ua noj nrog cov diav ntoo thiab txaus siab rau kev nthuav dav ntawm cov khoom ntoo. Peb txawm muab peb paintings nyob rau hauv ntoo ncej. Txawm li cas los xij, ntau tus neeg siv ntoo kom pom zoo, tsis txhob tso tseg xav tias peb yuav tau li cas ntoo uas yog lub hauv paus rau ntau yam hauv peb lub neej.

Yog tias koj xav paub yuav ua li cas sawmills txheej txheem ntoo, daim ntawv qhia tag nrho rau sawmills yuav muab tag nrho cov ntaub ntawv koj xav tau. Kawm txog cov txheej txheem sawmill hlais thiab yuav ua li cas cov cav ntoo nyoos tig mus rau cov khoom ntoo tiav. Peb yuav teb cov lus nug xws li:

SAWILL yog dab tsi?

Lub sij hawm sawmill tuaj yeem xa mus rau ob lub ntsiab lus sib txawv hauv kev lag luam. Thawj yog qhov chaw uas cov neeg zeb ntoo. Lub sawmill yog tag nrho cov av nyob rau hauv uas lub sawmill zaum - lub cav sort yard, milling machinery thiab thaj chaw uas cov ntoo planks raug txheeb thiab khaws cia. Lub sawmill tseem muaj thaj chaw nyob rau ntawm qhov chaw rau lub zeb kev tswj hwm thiab kev saib xyuas.

Lub sawmill kuj hais txog qhov tshwj xeeb txiav lossis sawing mechanism. Cov cav tov no tig cov cav ntoo mus rau hauv cov ntoo duab plaub rau siv hauv kev tsim khoom. Technically, kev lag luam sawmill hu cov tub ntxhais sawing tshuab lub taub hau rig, tab sis lub taub hau rig xav tau kev txhawb nqa dav dav kom ua haujlwm kom raug. Tej zaum qhov tseeb tshaj plaws txhais ntawm sawmill yog tias nws yog tag nrho cov kab ke uas hloov cov cav ntoo rau hauv ntoo.

Txawm hais tias koj siv lo lus los xa mus rau ib tus neeg sawing tshuab lossis tag nrho cov ntoo milling ua haujlwm, sawmills yog qhov chaw bustling. Feem ntau cov sawmills niaj hnub yog cov lag luam loj loj nrog cov khoom lag luam siab. Qee qhov chaw no ntiav ntau pua tus neeg ua haujlwm thiab teem sijhawm hloov pauv ib ncig ntawm lub moos kom khaws cov ntoo kom zoo.

Thaum twg SAWILL tau tsim?

Ua ntej kev tsim cov sawmill, tib neeg txiav, faib thiab npaj cov rooj ntoo los ntawm tes siv cov cuab yeej siv tes. Tom qab ntawd, tib neeg siv lub nplawm, ib rab riam ntev uas txiav cov cav thaum cov txiv neej rub lub saw. Cov txheej txheem no yog tedious thiab nkees thiab xav tau kev txhim kho.

Keeb kwm ntawm sawmills hnub rov qab mus rau Roman faj tim teb chaws. Thawj lub sawmill hu ua Hierapolis sawmill thiab hnub tim nyob ib ncig ntawm lub xyoo pua peb AD Lub sawmill tau tshawb pom thaum cov kws tshawb fawb tshawb fawb tshawb xyuas cov sarcophagus ntawm ib lub miller nyob rau niaj hnub Qaib Cov Txwv, dab tsi yog Asia Minor. Ntawm lub sarcophagus yog ib qho kev txhawb nqa ntawm lub pas dej nrog lub crank slider mechanism thiab ob lub saws txiav los ntawm cov blocks.

Roman waterwheel-powered pom sawv cev rau kev nce qib tseem ceeb hauv engineering thiab kev tsim khoom. Nyob ib ncig ntawm lub xyoo pua thib rau, cov dej-powered zeb sawmills tau tshwm sim thoob plaws lub tebchaws Byzantine. Los ntawm lub xyoo pua 11th, cov sawmills kis tau los ntawm Spain thiab North Africa mus rau Central Asia.

Leej twg tsim lub SAWILL?

Tus tsim ntawm sawmill tseem tseem zoo ib yam mus txog rau thaum Industrial Revolution, thaum ib tug neeg tsim lub voj voog saw hniav. Cov neeg sau keeb kwm feem ntau suav nrog Samuel Miller, uas tau txais txiaj ntsig British patent rau cov hniav hauv xyoo 1777. Lwm tus neeg hais tias Dutch tsim nws nyob rau xyoo pua 17th lossis tias nws yog American Shaker Sister Tabitha Babbitt. Leej twg tsim nws, lub bandsaw tus nqi siab thiab cov hniav tsis zoo txhais tau tias nws tsis tau siv dav mus txog rau thaum nruab nrab xyoo pua 19th. Niaj hnub no, cov sawmills feem ntau siv kev lag luam-qhov loj me band saws.

Kuv tuaj yeem tau txais dab tsi ntawm SAMILL?

Lub sawmill tuaj yeem tsim tau ntau yam ntawm txhua yam ntoo, txawm hais tias feem ntau sawmills tshwj xeeb hauv ib hom ntoo. Sawmills hauv North America ua ib qho ntawm ob hom ntoo, softwood lossis hardwood.

Cov ntoo Softwood yog evergreens lossis conifers nrog cov koob txuas mus tas li. Cov hom no muaj xws li cedar, ntoo thuv, spruce, hemlock, fir thiab redwood. Hardwood ntoo yog deciduous hom uas poob lawv nplooj nyob rau hauv lub caij nplooj zeeg thiab tsim tawm tshiab nyob rau hauv lub caij nplooj ntoos hlav. Cov tsiaj xws li walnut, maple, beech, cherry, elm thiab ntoo qhib yog tag nrho cov ntoo ntoo.

Cov hom no xav tau cov tshuab sib txawv thiab cov cuab yeej ua haujlwm. Qee cov sawmills yuav cov khoom siv los ua ob hom ntoo, txawm tias qhov no tsis tshua muaj. Feem ntau koj tuaj yeem pom cov ntaub ntawv softwood hauv cov kws ntoo ntxhib thiab lub tsev thav duab, uas lub teeb coj mus muag kev lag luam siv. Kev tsim vaj tsev nyob siv cov ntoo tawv ntoo rau cov khoom tiav xws li rooj tog zaum, flooring, staircases thiab plywood panels.

SAWMILLS POWERED li cas?

Raws li nrog rau ntau hom kev siv tshuab, sawmill lub zog tau hloov zuj zus mus rau ntau xyoo lawm. Cov thawj mills muaj waterwheels, uas muab txoj kev rau windmills. Ob lub tshuab no tau hloov pauv huab cua. Cov neeg ua haujlwm tsis tuaj yeem ua haujlwm ntawm sawmills yog tias qhov chaw dej qhuav los yog cua nres. Cov sawmills no kuj siv cov cranks tsis zoo thiab cov pas nrig uas tsis pom txuas ntxiv mus.

Thaum ntxov thiab nruab nrab xyoo pua -19, chav yog lub hauv paus ntawm lub zog rau sawmills. Cov sawmills tuaj yeem rov siv lawv cov pov tseg ntoo los ntawm kev siv cov khoom siv los ua cov roj boilers. Cov boilers powered turbine shafts, uas tig lub voj voog thiab band pom hniav. Cov boilers no tau siv feem ntau vim yog cov ntoo khib nyiab ntau, yog li cov roj hluav taws kub hnyiab tsis tau nrov nrov.

Los ntawm nruab nrab ntawm lub xyoo pua 20th, feem ntau cov sawmills nyob ruaj ruaj phased chav zog tawm thiab hloov nws nrog hluav taws xob. Lub zog hluav taws xob no tseem yog lub hauv paus tseem ceeb hauv kev siv niaj hnub no. Portable sawmills feem ntau tsis siv hluav taws xob vim tias cov chaw zeb uas siv lawv feem ntau tawm ntawm daim phiaj hluav taws xob. Es tsis txhob, mobile sawmills siv diesel thiab roj av hwj chim qhov chaw. Tam sim no tsis muaj kev hloov pauv loj rau lub hnub ci zog rau cov sawmills vim tias cov txheej txheem tsim khoom yuav tsum muaj ntau lub zog.

Dhau li ntawm tig cov hniav thiab conveyors, sawmills kuj xav tau lub zog rau lwm lub tshuab. Niaj hnub nimno sawmills siv computers los soj ntsuam cov cav thiab txiav txim siab qhov kev txiav txim siab zoo. Cov tshuab computer tom qab ntawd xa cov ntaub ntawv digitized rau cov sawmills kom tau raws li qhov xav tau txhua hnub. Tag nrho cov txheej txheem siab heev no xav tau lub zog hluav taws xob.
