Nyob rau hauv siab ntsev tsuag marine ib puag ncig, 6LTAA8.9-GM200 marine generator teeb diesel motors fim synergistic corrosion los ntawm saturated ntsev tsuag, av noo thiab kub, thiab acidic combustion khoom. Qhov nruab nrab txhua xyoo corrosion ntawm cov hlau substrate tuaj yeem ncav cuag 0.15-0.3 hli, yooj yim ua rau kev ua tsis tiav xws li poob ntawm lub tog raj kheej liner-piston nplhaib haum precision thiab txo turbocharger txias efficiency. Xeb- cuam tshuam txog kev poob qis rau 17.3%, thiab cov nqi kho mob yog 4.2 npaug siab dua rau xeb- cov khoom siv hluav taws xob tiv taus. Cov tswv yim tiv thaiv xeb uas paub tab hauv kev lag luam tsis yog kev sib xyaw ua ke ntawm ib qho kev ntsuas, tab sis yog qhov peb-dimensional system raws li cov khoom siv, nto engineering, thiab kev tiv thaiv kab ke. Cov txheej txheem no yuav tsum ua raws li ASTM B117 ntsev tshuaj tsuag tus qauv, DNV-GL specifications, thiab Tuam Tshoj Classification Society (CCS) "Cov Cai rau Kev faib tawm ntawm Cov Hlau Seagoing Nkoj."
Cov khoom siv qib yog lub hauv paus ntawm kev tiv thaiv, nrog rau lub hauv paus yog los txhim kho corrosion kuj los ntawm qhov chaw los ntawm cov khoom optimization.Rau cov txheej txheem tseem ceeb ntawm lub tshuab hluav taws xob teeb xws li 6LTAA8.9-GM200, corrosion-cov alloys resistant xws li 316L stainless hlau thiab txhuas bronze yog nyiam. Ordinary carbon steel Cheebtsam yuav tsum tau kub-dip galvanizing los xyuas kom meej zinc txheej thickness Ntau tshaj los yog sib npaug zos rau 85μm rau sacrificial anode tiv thaiv. Cov ntsaws ruaj ruaj yuav tsum zoo dua siv cov laus{11}}cov ntaub ntawv tiv taus xws li PTFE thiab EPDM. Cov khoom siv hluav taws xob siv cov dej noo{12}} pov thawj thiab mildew- cov ntaub ntawv pov thawj insulating, thiab cov kev sib cuag tseem ceeb yog kub - lossis nyiaj-plated los txhim kho corrosion.
Kev tsim kho lub cev tiv thaiv kev tiv thaiv ntawm cov txheej txheem saum npoo av tsom mus rau kev sib txuam ntawm cov txheej txheem txheej txheej thiab kev tswj xyuas kev tsim kho.Cov txheej txheem kev lag luam yog peb txheej txheej txheej txheej txheej: epoxy zinc- nplua nuj primer (qhuav zaj duab xis thickness 80μm, zinc hmoov cov ntsiab lus ntau dua los yog sib npaug rau 80wt%) + epoxy intermediate coat (100-120μm) + polyurethane topcoat (80μm). Tag nrho cov thickness sib txawv yuav tsum tau tswj nyob rau hauv ± 10%, thiab lub substrate nto yuav tsum ua tiav Sa2.5 huv huv theem thiab roughness tswj ntawm 40-75μm ua ntej daim ntawv thov los txhim kho txheej adhesion.
Lub hauv paus tseem ceeb ntawm kev ua tiav kev hloov pauv hloov pauv thiab lub sijhawm ntev - kev tswj hwm ntawm qib kev tiv thaiv kab ke yog nyob rau hauv kev sib koom ua ke ntawm kev ua kom zoo dua qub thiab kev tswj hwm ib puag ncig.Tus qauv tsim yuav tsum tsis txhob muaj dej tsub zuj zuj ntawm thaj chaw tuag, txhua qhov chaw yuav tsum muaj qhov dej ntws tsawg kawg yog 3 degree, cov khoom tseem ceeb yuav tsum siv cov ntsaws ruaj ruaj labyrinthine, thiab cov ntaub thaiv hluav taws xob yuav tsum tau tsim los rau IP56 cov qauv kev tiv thaiv. Hais txog kev tswj hwm ib puag ncig, chav tsev tsim hluav taws xob yuav tsum tau nruab nrog lub zog cua thiab dehumidification, thiab cov dehumidifiers me me yuav tsum tau muab tso rau hauv cov khoom hluav taws xob tseem ceeb los tswj cov av noo hauv chav hauv qab 50%, txo qhov kev pheej hmoo ntawm damp cua sov corrosion.
Lub ntsiab lus tseem ceeb ntawm peb - qhov kev tiv thaiv qhov ntev yog "kev tiv thaiv ua ntej, kev tiv thaiv txheej." Los ntawm kev sib koom ua ke ntawm cov khoom siv los tswj, qhov thaiv qhov thaiv qhov chaw, thiab kev tswj hwm lub cev muaj zog, lub neej kev pab cuam ntawm marine diesel xyaw nyob rau hauv qhov chaw muaj ntsev ntsev ntau tuaj yeem nce ntxiv los ntawm ntau tshaj peb zaug, thaum txo cov nqi kho tsis tau npaj tseg. Qhov no yog lub hauv paus kev lag luam thev naus laus zis ua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm marine generator teeb xws li 6LTAA8.9-GM200.
