Cov yeeb nkab kev lag luam yog ib feem tubular lossis lub tog raj kheej hollow, tab sis tsis tas yuav hloov. Nws yog siv ntau zaus rau kev thauj khoom, kua, roj, kev ncua, hmoov thiab cov khoom me me. Ntau hom kav dej siv hauv kev lag luam, lawv txawv tsis yog hauv txoj kab uas hla thiab cov khoom siv, tab sis kuj nyob rau hauv txoj kev ntawm installation. Lawv cov kev faib tawm yog qhov dav, tab sis kom nkag siab nws, koj yuav tsum kawm txog cov kav dej siv hauv ntau qhov kev lag luam.

Electro-welded industrial kav

Ua los ntawm cov hlau tsis tshua muaj hlau. Cov kav dej yog tsim rau cov kav dej thiab kev tsim kho, lawv yog siv rau cov kav dej, tab sis nrog cov tsis tshua muaj siab, hauv cov cua sov thiab cov kav dej. Hluav taws xob cov kav dej yog qhov txawv ntawm cov khoom siv, phab ntsa thickness, txoj kab uas hla thiab qhov raug ntawm kev tsim khoom. Cov kav dej zoo li no tau nthuav tawmcov qauv kev cai, lawv yuav tsum ua kom tau raws li qhov yuav tsum tau muaj lub zog, txhim khu kev qha thiab tiv taus qhov hnyav ib puag ncig. Txhawm rau kom ntseeg tau tias cov xwm txheej no, txheej txheej tshwj xeeb ntawm polyethylene yog siv rau cov kav hlau, tab sis nws yog qhov zoo dua yog tias cov yeeb nkab yog ua los ntawm cov hlau tsis huv. Cov duab ntawm cov yeeb nkab no txawv, feem ntau nws yog lub voj voog, square lossis duab plaub. Cov kav dej txuas nrog siv welds, uas tuaj yeem ua rau ntau txoj hauv kev: los ntawm plasma vuam mus rau electron beam vuam hauv qee hom kev lag luam.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.

Seamless industrial kav yog nrov dua li cov kav dej hluav taws xob. Lawv yog siv nyob rau hauv kev tsim kho cov dej thiab dej phwj system nyob rau hauv private tsev nyob, nyob rau hauv industrial kev sib txuas lus, shipbuilding thiab mechanical engineering. Ib qho ntxiv ntawm cov kav dej no yog tias cov dej xau ntawm cov kua los yog cov pa tawm los ntawm lawv tau raug cais tawm tag nrho los ntawm cov geometry ntawm cov yeeb nkab. Qhov tsis muaj seams nce tsis tsuas yog nruj, tab sis kuj nce kev ntseeg tau thiab kev pabcuam lub neej. Muaj ntau ntau txoj hauv kev los tsim cov yeeb nkab seamless: los ntawm kev kos duab mus rau dov. Cov khoom siv los ua raw khoom cuam tshuam rau lub peev xwm ntawm cov khoom. Kev siv ntau yam additives nyob rau hauv cov hlau alloy rau steel muab ob qho tib si elasticity rau cov yeeb nkab, los yog tsub kom hnav tsis kam thiab tsis kam mus rau ib puag ncig yam, thaum qhov zoo ntawm cov qauv tsis raug kev txom nyem los ntawm qhov no.

Tshuaj ntsuab. Keeb kwm

Qhov pib ntawm cov pa luam yeeb thiab cov kav dej ua pa yog coj los ntawm lub sijhawm qub, thaum tib neeg tso tawmpob zeb nyob ib ncig ntawm qhov hluav taws kub. Cov pa taws los ntawm qhov hluav taws kub tseem mus rau lwm qhov, thiab cov kav dej yuav tsum tau hloov mus. Furnaces nyob rau hauv Russia muaj tib yam tsim raws li qhov yooj yim chav ntawm cov neeg thaum ub. Soot accumulates nyob rau hauv cov yeeb nkab, yog li koj yuav tsum tau saib xyuas nws nruj thiab tiv thaiv kom tsis txhob xau. Tsis tas li ntawd, cov chimney yog xav tau los tsim cov cua ntsawj ntshab thaum lub sijhawm ua haujlwm ntawm chav boiler. Yav dhau los, lawv tau ua los ntawm cib, tab sis niaj hnub versions tsis loj thiab ua los ntawm cov hlau nrog thermal rwb thaiv tsev.

Kev xaiv qhov cub

Cov pa luam yeeb thiab qhov cua nkag tau muab faib ua pawg hauv qab no:

• kam hlau;
• tus kheej txhawb nqa hlau;
• pem hauv ntej;
• stretch marks;
• truss.

Cov kav dej hauv kev lag luam yog tsim los ntawm tus kheej, txawm tias lawv txhua tus muaj qhov ua haujlwm zoo ib yam, tab sis qhov chaw nyob hauv ib qho kev tsim khoom ua rau qee yam nta. Kev tsim cov yeeb nkab chimney tsuas yog ua los ntawm cov kws tshaj lij, ua raws li cov hauv qab no:

• gases yuav tsum dhau tag nrho qhov siab ntawm cov qauv, thiab raug tshem tawm mus rau qhov chaw raws li qhov chaw du;
• cov yam ntxwv ntawm cov cuab yeej dictate lub xam thiab txoj kab uas hla ntawm industrial kav los tsim "tus kheej rub" nyob rau hauv lawv;
• kev xav thiab kev tawg ntawm emissions yuav tsum tsis pub dhau qhov kev txwv.

Cov kav dej chimney yog raug rau cov kev cai tshwj xeeb tsis yog thaum lub sijhawm tsim khoom, tab sis kuj thaum lub sijhawm teeb tsa.

Key parameters of chimneys

Txhua qhov siab ntawm cov yeeb nkab muaj qhov sib txawvParameters - qhov no yog vim cov yam ntxwv ntawm cov pa hluav taws xob channel. Lawv txoj kab uas hla tuaj yeem ncav cuag 1.5 meters, xws li 0.2 meters. Raws li cov yam ntxwv tseem ceeb ntawm cov yeeb nkab, nws tuaj yeem muab ntxiv nrog cov khoom siv hauv daim ntawv ntawm tus ntaiv, lub laj kab teeb lossis lub pas nrig. Cov kav dej loj loj yog qhov nyuaj rau kev tsim khoom thiab xav tau kev txhawb nqa loj ntawm lub hauv paus thiab tag nrho lub cev.

Txoj cai rau lub tsev chimney suav nrog cov hauv qab no:

1. Kev txhim kho cov kav dej yuav tsum yog qhov zoo tshaj plaws rau qhov chaw teeb tsa ntawm boilers lossis lwm yam khoom siv rau kev tshem tawm cov roj pov tseg ntawm cov units.
2. Koj tuaj yeem nruab ib lub yeeb nkab, tab sis txuas ob peb lub cuab yeej rau nws ib zaug, thaum ua raws li txoj cai kev nyab xeeb. Qhov no tsis yooj yim tsuas yog vim tias txhawm rau tiv thaiv ib qho khoom siv, koj yuav tsum tua tag nrho lwm tus.
3. Kho qhov siab ntawm cov yeeb nkab thiab qhov tuab ntawm nws cov phab ntsa. Npaj lub qhov thev naus laus zis.
4. Txhim lub hauv paus hauv ib txoj hauv kev ua tau.

Kev faib tawm ntawm cov kav dej

Muaj ntau yam uas paub qhov txawv ntawm cov kav dej:

• qhov tseem ceeb yog qhov siab, muaj cov kav dej siab txog 180 meters, nruab nrab ntawm 60 txog 180 meters, cov kav dej qis qis dua 60 meters, pib ntawm 20;
• yeeb nkab hla ntu tuaj yeem yog puag ncig, duab plaub thiab square;
• sib txawv ntawm cov ntaub ntawv: cib, hlau, pob zeb, lossis tej zaum ua ke ntawm cov ntaub ntawv, piv txwv li, lub thoob yog ua los ntawm cov hlau, thiab cov casing yog ua los ntawmpob zeb;
• lub hom phiaj thev naus laus zis tuaj yeem tsis yog tsuas yog tshem tawm cov pa luam yeeb xwb, tab sis kuj yog rau qhov cua thiab qhov chaw nruj;
• kev tsim kho kuj txawv: cov kav dej tuaj yeem ua monolithic lossis prefabricated nrog ntau hom formwork;
• loj, nruab nrab lossis me txoj kab uas hla.

Technical elements

Qhov tseem ceeb uas cov kav dej muaj: lub hauv paus - lub hauv paus, lub cev thiab kev npaj ntxiv. Lub hauv paus tuaj yeem ua los ntawm cov pob zeb ua kom muaj zog, du lossis ribbed rau cov av tsis ruaj khov. Tso nws mus rau qhov tob nyob ntawm qhov xwm txheej huab cua, kev ua haujlwm thiab dej hauv av.

Cov yeeb nkab ncej muab faib ua peb ntu: lub cev, lub taub hau thiab hauv ob sab phlu. Lub cev, nyob rau hauv lem, muab faib ua consoles, txhua yam yog los ntawm 10 mus rau 20 m, nyob rau hauv nws muaj ib tug txheej ntawm refractory bricks los yog acid-resistant. Lub taub hau tiv thaiv los ntawm lub hau tshwj xeeb ua los ntawm cov hlau cam los ntawm kev yaig.
