Kev ua noj ua haus yeej ib txwm nrog cov khoom tsis zoo xws li pa taws thiab kua qaub. Chav ua noj hood nrog tus kais dej tuaj yeem tshem tawm cov kev tsis txaus no. Ib ceg yog qhov tseem ceeb hauv kev tsim cov kav dej lossis cov kav dej. Lub tswvyim, hom, yam ntxwv thiab yuav tsum tau rau installation ntawm ceg yuav tau tham nyob rau hauv kom meej nyob rau hauv tsab xov xwm no.
"kev thim rov qab" yog dab tsi?
Bent yog cov kav dej uas coj cov cua ntws mus rau qhov xav tau. Niaj hnub nimno hoods siv qhov hluav taws xob ua los ntawm ntau yam ntaub ntawv xws li dub, stainless hlau, galvanized hlau, txhuas los yog PVC.
Tsis tas li ntawd, muaj cov khoov uas tsim los rau sab nraud emissions. Lawv kuj tau nruab nrog cov phab ntsa tiv thaiv lossis cov ntawv perforated uas tiv thaiv cov khib nyiab los ntawm qhov cua.
txiaj ntsig ntawm diverter hoods
chav ua noj hoods nrog lub qhov cua rau qhov cua muaj ntau qhov zoo uas tsis tuaj yeem lees paub. Cov no suav nrog:
- qib siabntxuav;
- siab zog thiab kev ua haujlwm;
- kev txuag vim tsis tas yuav hloov cov lim cua;
- tus nqi pheej yig.
Thiab tau kawg, qhov tsis txaus ntseeg qhov zoo ntawm cov qauv zoo li no yog tshem tawm cov ntxhiab tsw ntxhiab sab nraud ntawm chav tsev, uas lav qhov ua kom zoo ntawm huab cua huv.
Qhov tsis zoo ntawm chav ua noj hoods nrog qhov hluav taws xob
Txawm li cas los xij qhov kev ntxias hood khoov zoo li cas, lawv tseem muaj lawv qhov tsis zoo. Qhov tsis zoo ntawm diverter hoods suav nrog:
- suab nrov;
- nyuaj mount lub hood;
- xav tau lub tshuab cua;
Tab sis raws li lub hom phiaj thiab lub hom phiaj ntawm lub hood, uas yog kev ntxuav chav los ntawm cov ntxhiab tsw tsw, hlawv thiab soot, tshem tawm yog qhov kev daws teeb meem zoo tshaj plaws rau kev ua tiav lub hom phiaj.
Kev faib cov kais dej
Nyob rau hauv kev tsim kho cov pa cua hauv tsev, cov qauv sib txawv ntawm chav ua noj hoods thiab, raws li, cov khoom siv sib txawv tau siv. Lub luj tshib raug cais raws li hom khoom siv rau lawv cov khoom:
- Galvanized khoov. Rau lawv cov khoom siv, cov hlau dub nrog nyias zinc txheej yog siv. Qhov zoo ntawm galvanized khoov yog tus nqi qis thiab corrosion kuj.
- Stainless hlau luj tshib. Lawv tsis tshua pom muaj nyob rau hauv duct designs vim lawv cov nqi siab. Cov qauv no yog tsim tshwj xeeb nrog ib txoj kab uas hla me me, rau kev teeb tsa hauv cov tshuab cua hauv tsev.
- Khoov ua los ntawm cov hlau dub. Roughing khoov feem ntausiv rau kev tsim kho ntawm industrial cua ducts. Lawv yog cov nqi qis. Lub ntsiab tsis zoo ntawm cov khoom no yog susceptibility rau corrosion thiab unaesthetic tsos.
- YPlastic khoov. Lawv tsuas yog siv rau kev tsim kho cov cua hauv tsev. Nyob rau hauv cov txheej txheem ntawm lawv cov khoom, cov ntaub ntawv polymeric yog siv uas tiv taus loads thiab deformations.
Cov kev cai tshwj xeeb siv rau txhua hom khoov. Lub luj tshib, GOST uas tau sau tseg rau txhua tus neeg lub npe, sib txawv ntawm lub zog, tuab, kev pabcuam lub neej thiab lwm yam.
Yuav xaiv ceg twg - yas lossis corrugated?
Cov qhov hluav taws xob nrov tshaj plaws yog cov yas lossis txhuas ducts. Yas khoov tuaj yeem yog puag ncig thiab duab plaub, thiab cov ducts corrugated tsuas yog puag ncig.
Thaum txhim kho cov kais dej, koj yuav tsum tau xyuam xim rau qhov zoo ntawm kev sib txuas ntawm txhua yam khoom siv. Yog li ntawd, thaum yuav lub qhov hluav taws xob yas, nws raug nquahu kom yuav tam sim ntawd cov khoom uas tuaj nrog nws, yog li ntawd yav tom ntej yuav tsis muaj teeb meem nrog kev teeb tsa ntawm cov kav dej. Nyob rau hauv lem, cov khoom corrugated tsis xav tau cov ntsiab lus ntxiv, vim lawv hloov tau yooj yim, thiab lawv tuaj yeem yooj yim ncab thiab compressed. Yog li ntawd, kev teeb tsa ntawm aluminium corrugated duct yog tsawg zog.
txheej txheem kev teeb tsa ntawm tus qauv no tsuas yog muaj ob theem: thawj zaug yog kho cov ntug ntawm cov yeeb nkab rau lub qhov cua, qhov thib ob yog txuas cov kav dej mus rau qhov hluav taws xob.hoods. Lwm qhov zoo ntawm corrugated aluminium ceg yog nws qhov hnyav. Cov kev tsis zoo muaj xws li: lub suab nrov, kwv yees ib yam li cov khoom siv hlau khoov, thiab cov khoom sib txuam ntawm cov rog, hlawv thiab soot hauv cov kav dej.
Yuav khoov yas zoo li muaj txiaj ntsig zoo ntawm kev ua haujlwm, vim tias lawv muaj kev tiv thaiv tsawg dua, tsis txhob ntim av thiab ua haujlwm yam tsis tsim suab nrov.
Khoov ntu
Ntxiv rau qhov kev faib tawm ntawm cov khoom khoov los ntawm cov khoom siv, thaum xaiv cov kav dej, muaj ntau yam yuav tsum xav txog, xws li cov duab ntawm cov kav dej thiab qhov kev teeb tsa ntawm lub ncej.
Thaum yuav cov kav dej, nws raug nquahu kom xaiv cov kab ciav hlau puag ncig, vim tias hom no muaj qhov zoo tshaj plaws aerodynamics. Tab sis yog tias chav ua noj nyob hauv ib chav me me, ces lub qhov hluav taws xob puag ncig yuav siv ntau qhov chaw thiab saib tsis zoo. Yog li ntawd, txhawm rau txhim kho lub hood nyob rau hauv ib chav me, nws yog qhov zoo dua los xaiv lub hood nrog lub voj voos. Xws li ib tug qauv yog mounted rau ntawm lub qab nthab thiab, raws li, yuav siv sij hawm tsawg chaw. Tab sis nws yog ib qho tsim nyog yuav tsum xyuam xim rau qhov tseeb tias thaum txhim kho lub voj voos, koj yuav tau ntxiv ntau lub adapters.
Khoov kab
Rau kev ua haujlwm zoo ntawm chav ua noj hood, nws yog qhov tsim nyog los xaiv txoj kab uas hla ntawm cov kav dej. Txhawm rau kom lub hood ua haujlwm yam tsis muaj suab nrov thiab tshem tawm cov pa paug kom zoo, koj yuav tsum xaiv khoov nrog qhov zoo sib xws.qhov hluav taws xob txoj kab uas hla. Txhawm rau xam lub cheeb ntawm qhov yuav tsum tau khoov, GOST tau tsim ib lub rooj tshwj xeeb rau kev xam cov diameters ntawm cov kav dej. Thaum siv cov kav dej nrog lub taub me me, lub zog tso tawm thiab, raws li, theem ntawm kev ua kom huv ntawm huab cua yog txo qis.
Ntxiv rau txoj kab uas hla ntawm lub qhov hluav taws xob, nws tseem tsim nyog saib xyuas seb nws nyob li cas. Thaum lub sij hawm installation ntawm cov kav dej, nws yog ib qho tseem ceeb kom tsis txhob muaj cov ntse ntse thiab txoj cai kaum. A 90 degree khoov poob mus txog 10% ntawm lub zog rho tawm.
Kev teeb tsa lub hood nrog lub qhov hluav taws xob
Txhim kho ib ceg kom zoo txhais tau tias kom nws ua haujlwm tau zoo thiab ua haujlwm zoo. Txhawm rau nruab ib lub hood extractor, koj thawj zaug yuav tsum xam qhov deb thiab qhov chaw ntawm lub hood saum lub qhov cub. Qhov chaw nruab nrab ntawm qhov tso pa tawm thiab lub qhov cub roj yuav tsum txaus kom lub hood tsis cuam tshuam nrog kev siv ntawm qhov chaw ua haujlwm ntawm lub qhov cub. Qhov kev ncua deb ntawm lawv yog 75 centimeters.
Thaum tsim lub kav dej, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev nkag mus rau cov huab cua hauv tsev yuav tsum tau tswj xyuas. Ua li no, mount ib qho tshwj xeeb cov hniav nyiaj hniav kub nrog lub valve hauv cov kav dej. Thaum lub hood ua haujlwm, lub valve kaw, thiab thaum nws raug tua, nws qhib kom ntseeg tau tias huab cua zoo li qub.
Thaum txhim kho steel lossis corrugated khoov, nws yuav tsum tau xav txog lawv txoj kev mus rau qhov cua. Vim yog kev txhim kho tsis raug ntawm cov kais dej, lub hood tuaj yeem poob txog 30% ntawm nws lub zog. Yog li ntawd, thaum xav txog txoj kev ntawm cov kav dej, xyuas kom meej tias cov yeeb nkab tsis muajntse los yog kaum sab xis. Raws li twb tau hais lawm, kev thim rov qab 90 degrees ntawm kev khoov ua rau txo qis hauv kev ua haujlwm ntawm cov pa tawm.
Txhawm rau txo cov suab nrov ntawm lub hood, koj yuav tsum tau ua tib zoo saib xyuas lub cheeb ntawm lub qhov hluav taws xob. Nws yuav tsum loj dua qhov hluav taws xob ntawm lub tshuab tso pa tawm. Hom ntaus ntawv kuj yuav tsum raug coj mus rau hauv tus account. Piv txwv li, cov hoods tiaj tus yog txuas rau ntawm phab ntsa, thaum cov kob hoods txuas rau lub qab nthab.
Yog tias koj ua raws li cov lus qhia yooj yim no, lub hood hauv chav ua noj yuav ua haujlwm tau zoo li qhov ua tau, tsis ua rau muaj kev cuam tshuam tsis zoo rau cov neeg nyob hauv tsev.
