Dab tsi yog qhov kev hem thawj loj tshaj plaws rau cov kav dej faus? Tsis muaj dab tsi ntau dua li qhov kev puas tsuaj los ntawm kev rov qab los ntawm kev sib haum xeeb thiab tsheb khiav. Qhov no tuaj yeem ua rau xau thiab kho, thiab tseem tuaj yeem cuam tshuam tag nrho cov kav dej. Ntau qhov dej num siv cov khoom siv yeeb nkab ib txwm muaj feem ntau ntsib cov teeb meem ntawm cov yeeb nkab tawg, thaum cov kav hlau kav hlau, nrog rau lawv cov khoom tiv thaiv zoo heev, tau dhau los ua cov kev daws teeb meem zoo rau cov kav dej faus.
Qhov kev sib haum xeeb ntawm cov kav hlau kav hlau yog tsim los ntawm lawv cov khoom siv tshwj xeeb. Tsis zoo li cov flake graphite qauv ntawm grey cam khwb cia hlau kav, ductile hlau kav tau txais kev kho mob spheroidization, uas ua rau ib tug spherical faib ntawm graphite nyob rau hauv cov yeeb nkab. Cov txheej txheem no ncaj qha txhim kho cov yeeb nkab lub zog, lub zog tensile, thiab kev cuam tshuam tsis zoo, ua rau lawv 2-3 zaug muaj zog dua li cov kav dej grey cam khwb cia hlau, yooj yim tiv nrog deformation thiab tensile zog los ntawm cov av sib haum xeeb.
Piv nrog cov kav dej ib txwm muaj
| Cov kav dej | Anti- muaj peev xwm daws teeb meem | Kev ua tau zoo tom qab teeb tsa |
| Grey cam khwb cia hlau / cement yeeb nkab | Ntau yam | Txawm hais tias me ntsis tuaj yeem ua rau nws tawg lossis tawg. |
| Ordinary steel yeeb nkab (rigid weld joint) | feem ntau | Kev sib haum xeeb loj tuaj yeem ua rau weld tearing thiab yeeb nkab deformation. |
| PVC / PE yas kav | nruab nrab | Yooj yim deformed thiab bulging; yooj yim rub- tawm thaum muaj chaw nyob loj. |
| Cov yeeb nkab hlau | zoo heev | Cov pob qij txha yooj yooj yim nqus kev sib haum xeeb, tiv thaiv cov yeeb nkab lub cev los ntawm kev tawg lossis tawg. |
Tsis tas li ntawd, tus qauv hloov pauv kev sib koom ua ke ntawm cov kav hlau kav hlau muaj qhov zoo tshaj plaws ntawm kev daws teeb meem. Thaum lub hauv paus tsis sib haum tshwm sim, qhov sib koom ua ke tau yooj yim tuaj yeem hloov pauv thiab nthuav dav hauv qee qhov ntau, yog li tshem tawm qhov kev ntxhov siab ntawm cov yeeb nkab thiab tiv thaiv cov yeeb nkab tawg los ntawm kev sib txuas nruj. Hauv qhov sib piv, ib txwm nruj- cov kav dej txuas tau yooj yim rau cov dej ntws tawm ntawm qhov sib koom ua ke tom qab lub hauv paus kev daws teeb meem, thiab tej zaum yuav ua rau tawg ntawm tag nrho cov kav dej.
Hauv kev siv tswv yim, cov kav dej hauv nroog thiab cov kav dej phwj tuaj feem ntau yog faus ob peb metres hauv av, nqa qhov hnyav ntawm qhov ntev - lub sij hawm tsheb khiav, lub tsev loads, thiab av siab. Cov kav hlau kav hlau tuav tswj kev ruaj ntseg txawm tias nyob rau hauv cov txheej txheem geological nyuaj. Qhov tseem ceeb tshaj, lawv muaj kev tiv thaiv corrosion zoo heev thiab kev pabcuam lub neej ntev tshaj 50 xyoo tom qab faus, txo cov nqi kho tom qab. Kev xaiv txoj cai faus cov kav dej yog sib npaug rau kev xaiv ntev -lub sij hawm ruaj ntseg rau koj qhov project. Kev tiv thaiv -kev daws teeb meem ntawm cov kav hlau kav hlau ua kom ruaj khov thiab txhim khu kev qha cov kav dej sib txuas ua haujlwm, muab kev thaj yeeb nyab xeeb rau koj!
Cov ntsiab lus
Yog tias cov kav dej faus siab raug xaiv thiab tsim ua raws li cov lus qhia tshwj xeeb, nws yuav tsis tawg thaum muaj kev ntxhov siab. Kev tawg yog tshwm sim los ntawm qhov tsis xws ntawm kev xaiv, kev tsim kho, lossis lub hauv paus.
Cov kav dej hlau, nrog rau lawv qhov siab - cov yeeb nkab steel lub cev thiab cov pob qij txha hloov tau yooj yim, yog cov khoom siv yeeb nkab uas nyiam tshaj plaws rau kev siv faus, muab kev tiv thaiv rau lub hauv paus kev daws teeb meem, deformation, thiab siab tsis kam. Lawv daim ntawv thov hauv nroog thiab kev lag luam faus siab - cov kav dej siab yog qhov paub tab heev.
