Asphalt Loading Arm (tseem hu ua asphalt loading / unloading arm) yog cov kua dej tshwj xeeb -cov cuab yeej siv tau tsim tshwj xeeb rau asphalt- qhov nruab nrab uas muaj qhov kub thiab txias, siab viscosity, thiab nyiam ua kom khov. Nws cov yam ntxwv tseem ceeb suav nrog kev quab yuam cua sov, siab - kub tsis kam, tiv thaiv- cov khoom nplaum, thiab ruaj ntseg sealing; Nws yog feem ntau siv rau kev thauj khoom thiab tshem tawm ntawm asphalt los ntawm txoj kev tsheb thauj khoom thiab tsheb ciav hlau tsheb.
I. Cov yam ntxwv tseem ceeb
1. Forced Heat Tracing thiab Rwb thaiv tsev (tseem ceeb tshaj plaws) Nruab nrog cov txheej txheem chav dej lossis hluav taws xob cov khoom siv hluav taws xob, tswj cov kav dej kub ntawm 180-220℃thoob plaws hauv cov txheej txheem los tiv thaiv asphalt los ntawm cua txias, solidifying, thiab clogging.
Cov kav dej loj, cov pob qij txha, thiab cov li qub yog tag nrho cov khoom siv hluav taws xob thiab cov txheej txheem rwb thaiv tsev, kom ntseeg tau tias tsis muaj qhov tsis muaj qhov "tuag" qhov twg thaum tshav kub kub tuaj yeem tshwm sim.
2. Siab-Tsub thiab Siab-Viscosity Resistance
Khoom siv lub cev: Carbon steel (piv txwv li, Q235B) los yog stainless hlau, muaj peev xwm tiv taus cov erosive ntws ntawm siab - kub asphalt (160-200℃).
Flow Channel Tsim: Loj txoj kab uas hla, lub vojvoog luv luv, thiab cov phab ntsa hauv cov phab ntsa kom txo qis cov dej tsis kam thiab ua kom haum rau kev txav ntawm cov kua dej khov heev.
3. Kev nyab xeeb thiab kev ntseeg siab (Cov qauv yeeb nkab nruj)
Rigid caj npab sib dhos ua ke nrog siab - lub zog tig pob qij txha (featuring ob txoj kev sib tw) tso cai rau kev hloov pauv tau 360 degree, tshem tawm tag nrho cov kev pheej hmoo cuam tshuam nrog cov hoses hloov tau yooj yim -xws li kev laus, tawg, lossis detachment.
Standard Emergency Breakaway Valve: Tsis siv neeg txiav tawm ntws thiab kaw cov kab hauv qhov xwm txheej ntawm kev sib tsoo lub nkoj thauj khoom, tiv thaiv kev xau.
Nta tiv thaiv- zoo li qub, tiv thaiv xob laim, thiab tawg- cov qauv tsim pov thawj, ua rau nws tsim nyog siv rau hauv qhov chaw muaj kev phom sij, tawg, thiab tawg.
4. Npog thiab Eco-Kev Ua Haujlwm Zoo
Siv submerged sab saum toj - thauj khoom lossis kaw hauv qab -unloading txoj kev los txo qhov volatilization ntawm asphalt fumes thiab emissions ntawm tsw.
Yuav nruab nrog vapor rov qab ports kom tau raws li ib puag ncig emission raws cai.
5. Kev ua haujlwm tsis muaj zog
Nta lub caij nplooj ntoos hlav -lub tog raj kheej- pab ntsuas qhov ntsuas uas tso cai rau ib tus neeg teb xov tooj yooj yim nqa, tig, thiab ntsaws caj npab nrog lub tanker.
II. Yuav tsum thov
1. Cov txheej txheem thiab kev ntsuas kub
Tracing Medium: Tsawg-siab saturated chav (0.4–0.6 MPa) yog qhov nruab nrab nyiam; qhov twg chav tsis muaj lossis txwv tsis pub, hluav taws xob taug qab (tus kheej- hom tswj) yuav raug xaiv los ua lwm txoj hauv kev.
Kev Tswjhwm Kub: Yuav tsum tau khaws cia ntawm Ntau dua lossis sib npaug li 160℃thoob plaws tag nrho cov txheej txheem thauj khoom / tshem tawm; Thaum lub sij hawm kaw los yog ncua sij hawm, qhov kub thiab txias yuav tsum tau khaws cia siab tshaj 120℃los tiv thaiv solidification.
Fluid Compatibility: Tsim nyog tshwj xeeb rau cov kua nplaum hnyav, xws li asphalt, roj hnyav, thiab thee tar.
2. Cov qauv tsim thiab kev teeb tsa
Hom: Feem ntau tau teeb tsa raws li sab saum toj - thauj khoom caj npab nrog submerged filling peev lossis hauv qab - rub caj npab nrog lub kaw lus kaw. Immersion Depth: Thaum lub sij hawm thauj khoom sab saum toj, lub nozzle ntawm lub caj npab thauj khoom yuav tsum tau muab tso rau ntawm qhov deb tsawg dua lossis sib npaug li 200 hli los ntawm hauv qab ntawm lub tsheb thauj khoom (submerged loading) kom txo qis kev sib tsoo thiab hluav taws xob zoo li qub.
Cov ntsaws ruaj ruaj: Yuav tsum siv siab -kub- tiv taus Fluororubber (FKM) lossis Polytetrafluoroethylene (PTFE), muaj peev xwm tiv taus qhov kub siab tshaj lossis sib npaug li 250℃.
3. Kev ruaj ntseg thiab ib puag ncig yuav tsum tau muaj
Cov Khoom Siv Kev Nyab Xeeb: Yuav tsum tau nruab nrog lub valve thaum muaj xwm txheej ceev, tiv thaiv - qhov system hauv av zoo li qub, kev tiv thaiv dej ntws, thiab kev ntsuas kub ntsuas kub.
Kev Ua Haujlwm Platform: Ib lub platform uas tsis yog- plam platforms, guardrails, thiab tus ntaiv nkag mus rau kev nyab xeeb yuav tsum tau muab los ua kom muaj chaw ua haujlwm txaus thiab muaj kev nyab xeeb ua haujlwm.
Exhaust Gas Treatment: Yuav tsum tau ua ke nrog asphalt fume collection thiab purification system (xws li, condensation + activated carbon adsorption).
4. Kev tu thiab kev ua haujlwm yuav tsum tau ua
Preheating: Ua ntej siv, qhib lub tshuab cua sov kom tsawg li 30 feeb; xyuas kom meej tias lub raj xa dej tsis muaj kev cuam tshuam ua ntej pib hloov khoom.
Kev Tu: Thaum ua tiav cov haujlwm, tshem tawm cov txheej txheem siv cov roj thermal lossis chav kom tshem tawm cov asphalt seem.
Kev tshuaj xyuas: Ib ntus tshuaj xyuas qhov ntsuas kub ntawm qhov ntsuas kub, cov ntsaws ruaj ruaj, cov pob qij txha, thiab lub valve tawg; tam sim ntawd ua kev kho yog tias pom muaj cov dej xau lossis cov khoom siv kho tshuab.
III. Siv tau Scenarios
Petrochemical nroj tsuag, asphalt cia depots, hloov kho asphalt ntau lawm chaw
Txoj kev loj / hauv nroog asphalt sib xyaw cov nroj tsuag, tank tsheb thauj khoom / tshem tawm cov khoom siv
Kaw-kev thauj khoom thiab kev thauj khoom ua haujlwm rau cov tsheb ciav hlau thiab cov tsheb thauj khoom thauj asphalt
