Cov txheej txheem ntawm Ntxuav Cua Txias Txias

Ob sab yuav tsum tau saib xyuas: huab cua sab (fins, soot, roj-carbon deposits) thiab dej-sab (scale, sludge, sediment). Peb hom kev tu lub ntsiab: hauv kev pabcuam hauv online tu, hauv-situ offline tu (lub cav nres), thiab kev tshem tawm tag nrho kev cob qhia tu.

Ua rau kev ntxuav: nce cua-sab siab poob, siab dua qhov cua qhov hluav taws xob kub, cov pa taws dub, txo lub zog ntawm lub cav. Nco ntsoov ua raws li cov lus qhia ntawm tus tsim cav; siv CAC-compatible marine chemicals, zam corrosive agents uas tua Cu-Ni / titanium raj thiab fins.

 

1. Kev Pab Cuam Hauv Online Tu (lub cav khiav, tsis muaj kev kaw)

Siv rau niaj hnub lub teeb fouling, 2-stroke lub ntsiab cav feem ntau siv los ntawm built-in dosing unit.

Paub meej tias lub tshuab tsim hluav taws xob tso cai rau kev txhaj tshuaj hauv online; hnav PPE.

Khiav lub cav ntawm qhov ruaj khov ib nrab / ntsuas load. Qhib CAC scavenge drain valves.

Txhaj tshuaj tshwj xeeb marine charge-air-cooler cleaner rau hauv lub cev cua ntawm CAC raws li tau teev tseg.

Ua kom lub cav khiav mus rau lub sijhawm nyob, cov tshuaj yaj cov kua qaub & roj-carbon deposits. Dissolved pov tseg ntws tawm ntawm scavenge drains mus rau bilge / slop tank (kho tshuaj khib nyiab ib MARPOL).

Ua cov tshuaj yaug dej tshiab.

Kaw cov dej ntws; saib xyuas tus nqi-cua siab poob thiab qhov hluav taws xob kub tom qab ntxuav.

Kev txwv: Tsis tuaj yeem tshem tawm qhov hnyav hnyav / tuab carbon txheej; tsuas yog rau lub teeb saib xyuas lub sijhawm.

 

2. In-site Offline Cleaning (lub cav nres, CAC tseem haum rau lub cav)

Rau nruab nrab-heavy air-side fouling; nkag los ntawm kev soj ntsuam manhole / cua lub taub hau npog.

Cov kauj ruam saum huab cua

Nres & kaw-tawm cav, cais cov rotating qhov chaw. Qhib kev tshuaj xyuas npog; qhib tag nrho CAC ntws li qub.

Tshem tawm cov khib nyiab nrog cua compressed qis (tshuab los ntawm huab cua huv si; tsis txhob muaj cua txias, yuav khoov fins). Tighten bent fins nrog fin zuag.

Txau / ncig tau pom zoo CAC tshuaj ntxhua khaub ncaws hla fin pob. Cia lub sij hawm nyob twj ywm 60-120 min rau carbon-roj deposit breakdown. Max tshuaj kub 50 degree.

Tsawg-nruab nrab-siab-dej-dej dav hlau ntxuav lub fin nto, yaug tag nrho cov seem yaj. Sau tag nrho cov dej khib nyiab.

Tshuab ziab nrog cua compressed. Paub meej tias cov dej ntws tawm meej, tsis muaj tshuaj lom. Kaw tshuaj xyuas npog & cov dej ntws.

Water-side in-site tu (LT-dej-dej circuits sab)

Cais & ntws CAC qis-kub txias-dej Circuit Court. Tshem tawm cov dej-box kawg npog.

Mechanical: Mos rodding / low-pressure water lancing flush tube internals kom tshem tawm sludge & soft scale.

Rau cov limescale nyuaj: Circulate inhibited descaling tshuaj tov los ntawm raj pob, nruj me ntsis tswj lub sij hawm & pH nqi.

Full neutralization + ntau yam dej tshiab.

Pom kev soj ntsuam lub raj ntawv & raj; tshawb xyuas pitting / yaig. Rov kho qhov kawg npog, ntsuas-kuaj dej-sab ua ntej recommissioning.

3. Dismantled Rhiav Kev Tu (hnyav fouling, to xau suspicion, loj overhaul)

Tshem tawm tag nrho CAC chav tsev ntawm lub cav thiab xa mus rau rhiav; qhov ua tau zoo tshaj plaws.

Tshem tawm CAC los ntawm lub tshuab cua txias thiab cov kav dej txias.

Air-side Options:

Immersion da dej: submerge core nyob rau hauv kev pom zoo rhuab CAC nqus tsev vacuum rau 2-8 teev; agitate daws.

Circulation tshuaj ntxuav.

Maj mam qhuav-dej blasting (yeem, xoom-residue rau hnyav hnyav, pheej hmoo ntawm kev puas tsuaj yog tias kho tsis raug).

Ua kom tiav multi-theem dej tshiab yaug, puv dej & qhuav. Ncaj fins puas.

Dej-sab: tshuaj lom neeg descaling, yaug, tshuaj xyuas txhua lub raj.

Yuav tsum tau ua tom qab ntxuav:

Kev ntsuas dej-sab hydrostatic siab; air-side leak test. Tshawb xyuas cov raj-rau-tube-daim ntawv xau.

Tshawb xyuas lub raj; ntsaws cov raj xau (max ~ 10% tag nrho cov raj tso cai, ib lub cav OEM txwv).

Cov ntaub ntawv kev ntsuas siab-poob thiab cov ntaub ntawv ua haujlwm thermal ua ntej rov nruab rau ntawm lub nkoj.

 

Kev Nyab Xeeb Tseem Ceeb & Kev Ua Tsis Zoo

❌ High-pressure dej dav hlau ncaj qha mus rau fins → fin dabtsi yog khoov, ua haujlwm tsis tu ncua

❌ Siv tsis tau pom zoo aggressive acids ntawm Cu-Ni / Ti khoom → tube corrosion tsis ua hauj lwm

❌ Lub sijhawm nyob tsis txaus lossis tsis ua tiav → cov tshuaj lom neeg ua kom nrawm rau yav tom ntej fouling

❌ Khib nyiab pov tseg direct overboard: yuav tsum sau & pov tseg raws MARPOL yuav tsum

❌ Hla kev sim siab tom qab ntxuav → zais lub raj xau ua rau dej rau hauv lub tog raj kheej, kev pheej hmoo ntawm hydraulic xauv

 

Daim ntawv txheeb xyuas tom qab ntxuav

Huab cua-sab sib txawv siab rov qab los ze rau tus nqi hauv paus

Charge-air qhov hluav taws xob kub raws li lub cav specification nyob rau hauv tag nrho cov load

Tsis muaj dej ntws tawm sab nraud; tsis muaj dej los ntawm scavenges drains

Tag nrho cov dej ntws kaw; tshuaj xyuas npog kom raug kaw
