Vim li cas yog lub cev cua sov-tracing xaiv rau bitumen loading caj npab?
Cov qauv cua sov-tracing yog qhov tseem ceeb rau asphalt thau khoom caj npab vim tias asphalt muaj cov khoom khov kho ntawm cov khoom kub qis, cuam tshuam txaus thaum thauj khoom / thau khoom.
Cua sov-tracing qauv yog qhov tseem ceeb rau bitumen loading caj npab vim yog cov khoom siv lub cev tshwj xeeb ntawm bitumen thiab kev nyuaj thaum nws hloov chaw.
Tiv thaiv solorification:
Bitumen solidifies sai sai ntawm huab cua kub (feem ntau qis dua 80-100 degree). Cua sov tracing tswj cov me ntsis qhov kub thiab txias saum toj no nws cov khoom muag muag thiab ua kom muaj cov kua thiab tso tawm thaum thauj khoom / thau khoom.
Saib xyuas viscosity:
Bitumen lub viscosity nce txaus raws li nws txias, ua rau nws nyuaj ntws. Cua sov tracing kom muaj viscosity, enabling du hloov los ntawm cov raj xa dej thiab tsis txhob thaiv.
Kub-rhiab Bandling:
Bitumen yuav tsum tau muab khaws cia thiab pauv tsis pub dhau qhov kub tshwj xeeb (150-190 degree). Lub tshuab cua sov-tracing system muab cov cua sov kev tswj, tiv thaiv kev kub dhau (uas ua rau muaj kev zoo siab (uas ua rau muaj kev tawv ncauj).
Kev Ua Haujlwm:
Tsis tas yuav muaj cua sov, txias bitumen yuav xav tau cov pipeline nquag pipging lossis tshuab scraping, ua rau poob qis, cov nqi hluav taws xob, thiab cov nqi txij nkawm, thiab cov nqi txij nkawm, thiab tus nqi txij nkawm. Cua sov tracing kom ua kom muaj kev vam meej txuas ntxiv, ua haujlwm tau zoo.
Kev yoog raws ib puag ncig cov xwm txheej:
Hauv cov huab cua txias lossis thaum lub caij ntuj no, ambient qhov kub kub ceev bitumen txias. Chav lossis hluav taws xob cua sov tracing nyiaj rau cov cua sov poob, ua kom muaj kev txhim khu kev qha thawm xyoo.
Kev nyab xeeb thiab kev ntseeg tau:
Solidified bitumen nyob rau hauv cov pipelines poses poses qhov txaus ntshai kev nyab xeeb (piv txwv li, kev ua tiav valve, siab tsim). Cua sov tracing mitigates cov kev pheej hmoo no los ntawm kev tswj hwm kev ncaj ncees.
Cov kev ua cua sov uas nquag ua rau bitumen load loading caj npab:
Chav Tracing: siv cov khaub ncaws ntim cov khaub ncaws lossis cov hlab kom hloov cua sov (raug nqi zoo rau cov haujlwm loj-ua haujlwm).
Fais Tracing: ua haujlwm cua sov cables kom zoo dua qhov kub thiab txias (hloov tau yooj yim, haum rau chaw deb).
Rwb thaiv tsev kev koom ua ke: ua ke nrog kev taug kev kom sov los txo lub zog poob zog.
Cov Ntawv Thov:
Dav siv nyob rau hauv bitumen terminals, txoj kev siv cov khoom siv khoom, thiab kev tswj hwm lub tsev vov tsev, uas tswj cov bittumen lub xeev ua haujlwm yog qhov tseem ceeb rau kev ua tau zoo thiab tsim khoom.
