cov kav dej ceramic muaj ntau niaj hnub no, vim tias lawv muaj cov yam ntxwv zoo heev. Lawv tuaj yeem siv los daws teeb meem kev lag luam thiab tsev neeg. Lawv yog tsim los ntawm cov av nplaum raug rho tawm haujlwm, uas yog them nrog glaze thaum lub sij hawm tsim khoom. Cov khoom yog cov yam ntxwv los ntawm kev ua haujlwm siab thiab qib zoo heev ntawm kev tiv thaiv sab nrauv tsis zoo. Tej zaum cov khoom no kuj tsim nyog rau koj yog tias, piv txwv li, koj tab tom npaj yuav nteg cov kav dej.

ntau yam tseem ceeb

Hnub no, ob peb hom kav dej ceramic tau paub, cov khoom no tuaj yeem siv rau ntau qhov chaw. Ntawm lwm cov kav dej, nws yuav tsum tau sau tseg:

  • sej;
  • dej;
  • rau cua sov thiab dej;
  • rau roj boilers thiab qhov cub chimney.

Scope of application

cov kav dej ceramic tau dav siv niaj hnub no. Lawv tuaj yeem siv rauindustrial thiab tsev neeg xav tau kev pab. Piv txwv li, dej phwj tuaj yeem tiv taus hnav, tsis hnov tsw ntawm qhov kub thiab txias, tsis txhob xeb thiab yuav luag tsis muaj tshuaj lom.

Cov kav dej zoo li no yooj yim rau kev teeb tsa, uas yog ntxiv kev txhawb nqa los ntawm cov thev naus laus zis niaj hnub. Cov khoom piav qhia kuj yog siv rau kev teeb tsa cov kav dej. Lawv tau ua tiav los ntawm qhov thiab muaj lub zog siab. Cov kav dej ntws tau hloov pauv tau, vim lawv tau nruab nrog cov txuas tshwj xeeb.

Ceramic kav kuj siv rau microtunnelling. Cov khoom no muaj ib txoj kab uas hla impressive, siab nruj thiab lub zog. Cov kav dej yog siv tsis tau tsuas yog rau kev tsim kho ntawm cov kav dej, tab sis kuj rau cov cua sov, dej thiab roj. Ceramic kav yog dav siv rau chimneys ntawm boilers thiab furnaces, thiab yog ua los ntawm kub-resistant ceramics. Kev sib dhos yog nqa tawm los ntawm cov ntu sib txawv, cov khoom tau them nrog nthuav av nplaum plhaub lossis iav hlau, uas tiv taus xeb.

Tsev tsim khoom

cov kav dej ceramic yog tsim los ntawm kev tua cov av nplaum thiab lwm yam khoom siv tsis zoo. Quartz xuab zeb qee zaum ntxiv rau cov khoom siv tseem ceeb, uas ua rau cov khoom siv ruaj khov thiab ua rau lawv lub neej ua haujlwm ntev. Cov txheej txheem tsim khoom yog raws li nram no. Nyob rau thawj theem, cov khoom siv raw yog npaj - molding loj yog tsim los ntawm kev sib tsoo av nplaum.

kauj ruam tom ntej yog molding ntawm cov khoom, nyob rau hauv tus txheej txheemRau qhov no, ntsia hlau ntsug lub tshuab nqus tsev presses, uas tso cai rau lub qhov (socket) tsim thiab cov kav dej yuav raug txiav. Cov khoom yog qhuav thiab raug rho tawm haujlwm hauv qhov cub. Cov kav dej ceramic yog ces dipped rau hauv glaze muaj pes tsawg leeg, thaum lub pas dej ua ke siv.

Technology nta: pipeline txiav

Kev txiav cov raj xa dej, cov tshuab sib tsoo feem ntau yog siv, cov khoom ua haujlwm uas yog lub zog siab pob zeb diamond discs. Cov kav dej ceramic tuaj yeem txiav mus rau qhov ntev siv cov yeeb nkab cutters tshwj xeeb tsim rau cov khoom lag luam.

Thaum siv cov txheej txheem cov yeeb nkab cutters, nws tuaj yeem txiav cov kav dej uas nws txoj kab uas hla txawv ntawm 50 mus rau 150 hli. Ua ntej, fixation yog ua nyob rau hauv lub pipeline, thiab ces - zawm nrog ib tug ratchet mechanism. Cov rollers ntse txiav rau hauv qhov chaw thiab cov khoom tawg hauv qhov chaw uas muaj kev ntxhov siab loj tshaj plaws.

Cov khoom lag luam tau piav qhia tau ua pov thawj lawv tus kheej zoo hauv kev tso dej thiab kev tsim kho cov kav dej, nrog rau kev tso roj, dej thiab cua sov. Qhov kev nthuav dav no yog vim ntau yam, ntawm lawv:

  • corrosion resistance;
  • abrasion tsis kam;kub tsis kam;
  • resistance to aggressive chemicals.

Qhov txiaj ntsig ntxiv yog lub peev xwm sivmovable couplings thaum tso cov kua dej.

Ceramic Pipe Standards

Ceramic kav dej yog tsim raws li lub xeev cov qauv 286-82. Tom qab tshuaj xyuas lawv, koj tuaj yeem pom tias cov kev cai tshwj xeeb raug txwv rau cov khoom tau piav qhia. Piv txwv li, tus qauv tsim muaj peev xwm tiv taus siab, qib uas yog 0.2 MPa. Cov khoom yog resistant rau acids nyob rau hauv 90%. Nws yog ua tsaug rau cov yam ntxwv no uas cov kav dej no feem ntau siv rau kev teeb tsa ntawm cov kav dej tsis muaj zog.

Txoj kab uas hla tuaj yeem txawv ntawm 100mm txog 600mm. Qhov ntev ntawm cov yeeb nkab tsis pub tshaj 1500 hli, thaum phab ntsa thickness tuaj yeem sib txawv ntawm 20 mus rau 40 hli. Ceramic kav rau cov kav dej phwj tuaj yeem muaj lub qhov (socket). Kev sib koom ua ke ntawm cov kav dej phwj yog nqa tawm siv cov xauv ua los ntawm cov av nplaum, tshwj xeeb mastics lossis asbestos cement. Txoj kab uas hla ntawm lub tswb sab hauv feem ntau yog ib daim duab ntawm 224 txog 734 mm.

Cov kav dej ceramic

cov kav dej ceramic yog tsim los ntawm cov av nplaum yas, uas muaj ntau yam tshuaj ntxiv los txhim kho cov yam ntxwv zoo ntawm cov khoom. Nyob rau hauv cov txheej txheem ntau lawm, txoj kev molding yog siv los ntawm txoj siv tawv los yog cov xovxwm tshwj xeeb. Kev tua hluav taws yog siv cov nplaim hluav taws kub. Cov kav dej yog glazed rau sab nraud.

Yog tias peb tham txog cov khoom siv hauv lub qhov (socket), ces lawv muaj qhov uas cov dej nkag mus. Tab sis lawv tau qias neeg sai sai. Tsis ntev los nofeem ntau xyaum yog kev tsim cov kav dej zoo li no tsis muaj lub qhov (socket). Ceramic couplings yog siv los cuam tshuam cov ntsiab lus thiab tiv thaiv silting. Sab hauv, dej kuj tuaj yeem nkag los ntawm cov pob qij txha. Txoj kab uas hla ntawm cov kav dej ceramic rau cov kua dej yog sib npaug ntawm qhov txwv ntawm 25 mus rau 250 mm. Qhov ntev tuaj yeem sib npaug li 335 hli siab tshaj plaws, qee qhov kev ntsuas no yog 500 hli. Cov khoom zoo li no yog ua los ntawm Frost-resistant, yog li lawv npaj txhij mus rau 15 lub caij khov thiab thaw mus.

Kev xaiv rau kev siv cov kav dej ceramic ua ke nrog cov khoom siv cua sov

cov kav dej ceramic feem ntau yog siv los tshem tawm cov pa roj uas yuav muaj qhov sib txawv. Tab sis cov khoom zoo li no haum rau cov khoom siv uas khiav ntawm cov khoom siv roj, uas yog:

  • charcoal;
  • coke;
  • baby;
  • pellets.

Cov kav dej kuj tseem siv rau cov roj ua kua, nrog rau cov roj boilers thiab qhov cub. Qee cov kav dej tsuas yog rau cov boilers uas tsis kub kub xwb.

Cov qauv ntawm cov raj ceramic rau cov khoom siv rauv

Lub tshuab hluav taws xob lub tshuab hluav taws xob muaj qee yam qauv. Lub plhaub sab hauv yog ua los ntawm ceramics, thaum nruab nrab txheej yog ua los ntawm cov cua sov insulator. Pob zeb thaiv feem ntau yog siv los ua lub plhaub sab nrauv.

Cov pa luam yeeb ceramic nyob rau sab saum toj muaj cov ntsiab lus rau kev khaws cov dej noo thiab nws tshem tawm. Cov yeeb nkab yuav tsum muaj cov khoom tiv thaiv los nag thiab cua. Tus qauv tsim yog ua tiav los ntawm cov khoom siv rau kev tu thiab tu, nrog rau kev sib txuas rau cov khoom siv.

Vim li cas thiaj xaiv Ceramic Piping

Qhov txiaj ntsig tseem ceeb ntawm cov khoom siv ceramic, uas tsim lub hauv paus ntawm cov kav dej rau ntau lub hom phiaj, yog lub peev xwm los hloov qhov kub thiab txias. Cov khoom yuav raug cuam tshuam los ntawm cov tshuaj uas tsis tuaj yeem hloov cov khoom ntawm cov yeeb nkab.

Cov khoom lag luam tiv taus kev puas tsuaj thiab cov txheej txheem corrosion. Nrog lawv cov kev pab, nws muaj peev xwm nteg cov kab ke hauv kev sib haum xeeb yam tsis muaj kev puas tsuaj rau txoj kev thiab kev taug kev. Cov kav dej ntws tau yooj yim heev, thiab cov ntsiab lus ceramic tuaj yeem txuas nrog txawm tias cov kav dej ua los ntawm lwm cov ntaub ntawv.

Zaj lus

Ceramic pipeline kuj zoo vim tias nws tuaj yeem muaj ntu ntawm cov duab sib txawv. Feem ntau, cov kav dej ntawm lub semicircular, puag ncig, elliptical lossis duab plaub. Feem ntau yog cov khoom tseem ceeb nrog ib puag ncig hla ntu. Nyob rau tib lub sijhawm, kev ua haujlwm pheej yig dua, thiab cov raj xa dej muaj qhov tsim nyog hydraulic yam ntxwv thiab txawv los ntawm kev ua haujlwm siab thiab kev ua haujlwm zoo.
