Xav txog cov yam ntxwv ntawm 6LTAA8.9-M315 marine engine (turbocharging + air-to-air intercooling, precision fuel injection system, thiab lwm yam) thiab cov txheej txheem kev txhim kho corrosion ntawm ib puag ncig navigation (humidity, ntsev tsuag), txo nws cov kev pheej hmoo corrosion yuav tsum tau tsom rau "engine type-compatibility." + Cov kev ntsuas tseem ceeb tuaj yeem muab faib ua peb qhov loj me, txhua qhov tsim los tsom rau lub cav tsis muaj zog corrosion:
I. Txhim kho lub hom phiaj tiv thaiv cov khoom tseem ceeb (thaiv qhov chaw ntawm corrosion)
Huab cua-rau- huab cua intercooler tiv thaiv: Siv lub plasma- tsuag ZrO₂-TiN ceramic txheej rau cov txhuas alloy fins txhim kho ntsev tsuag tiv taus ntau tshaj 5000 teev.
Turbocharger tiv thaiv: Siv nano-tus kheej- kho txheej rau martensitic stainless hlau impeller ua rau pitting corrosion tshwm sim los ntawm chloride ions hauv ntsev tsuag, ncua kev nthuav tawm ntawm qaug zog tawg hauv cov hniav.
Kev Tiv Thaiv Roj Txhaum Cai: Nruab ib lub twj tso kua mis hydrophobic ntsev interceptor nrog cov khoom siv hauv cov yeeb yaj kiab hydrophobic ntawm lub tank roj los thaiv qhov kev nkag ntawm submicron - qhov loj ntawm cov ntsev tsuag cov khoom.
Kev Tiv Thaiv Sab Nraud Sab Nraud: Hloov cov cav hluav taws xob txuas nrog IP67-rated ntsev tshuaj tiv thaiv thiab cov dej tsis sib txuas los txhim kho kev ua haujlwm rwb thaiv tsev hauv cov av noo ib puag ncig.
II. Optimize System Maintenance Strategies (Delay Corrosion Transmission)
Roj System: nruj me ntsis tswj roj noo cov ntsiab lus (tsawg dua los yog sib npaug rau 0.1%) los tiv thaiv lubricant emulsification; ntxuav lub lim roj tsis tu ncua.
Lubrication System: Siv los tiv thaiv -emulsifying lubricating roj; kuaj cov roj noo thiab cov ntsiab lus impurity txhua 2000 teev; Hloov cov laus lubricating roj kom sai los tiv thaiv cov av noo los ntawm kev nkag mus rau hauv lub crankcase thiab ceev piston tus pin thiab bushing hnav thiab corrosion.
III. Kho Kev Kho Lub voj voog Kho kom haum rau kev taw qhia ib puag ncig (Dynamic Prevention and Control)
Raws li ISO9223 ntsev tsuag tshuaj ntsuam xyuas tus qauv, kho ntau zaus raws li qhov sib txawv ntawm qhov chaw navigation: Nyob ze - ntug dej hiav txwv ntsev tsuag thaj chaw siab ( ntsev concentration> 5g / m³), kuaj xyuas corrosion txhua 1500 teev; nyob rau hauv qhov chaw qhib - dej hiav txwv cov av noo thiab kub (RH feem ntau> 85%), xyuas cov corrosion thiab scale buildup ntawm core Cheebtsam xws li piston txias raws, lub tog raj kheej phab ntsa, thiab turbine impellers txhua txhua 2000 teev, thiab ntxuav los yog kho tam sim ntawd.
