Ntsiab lus:Gas turbine; Lubricating roj kua roj vanish; MPC xeem; nqi adsorption pom; pauv resin
Gas turbine yog ib qho ntawm cov khoom tseem ceeb ntawm offshore platform.Nws yog siv los ua cov cuab yeej tsim hluav taws xob rau ntawm ntug dej hiav txwv platform kom ntseeg tau tias kev ua haujlwm ruaj khov thiab ntev lub voj voog ntawm cov roj turbine kom ntseeg tau qhov kev tsim tawm ntawm ntug dej hiav txwv.Cov roj turbine yog nyob rau hauv qhov kub thiab txias, kev kub siab thiab kev kub ceev thaum lub sij hawm ua hauj lwm, thiab cov kua roj vanish yog ib qho yooj yim los tsim nyob rau hauv qhov chaw no.Nyob rau tib lub sijhawm, nrog rau kev txhim kho cov roj zoo hauv cov roj lubricating, lub peev xwm ntawm lubricating roj dissolving kua roj vanish deteriorates, uas kuj intensifies lub ceev tsim ntawm cov kua roj vanish.Kev tsim cov kua roj vanish ua rau tsub zuj zuj ntawm cov kua roj vanish, muaj kev puas tsuaj loj rau cov khoom siv, nws yuav ua rau txo qis kev tshem tawm, nce hnav, valve core adhesion cov cuab yeej ua haujlwm tsis ruaj khov thiab txawm tias tsis ua haujlwm;cov kua roj vanish tso rau ntawm ncej, txias thiab lwm yam khoom ua rau qhov kub thiab txias hloov pauv ntawm cov ncej cua txias, cov roj oxidation acceleration: cov kua roj vanish yuav txuas rau cov khoom siv, thaiv cov khoom lim thiab lub qhov throttle, ua rau cov khoom siv thiab cov khoom siv tsis zoo. lubrication, domestic thiab txawv teb chaws roj turbine txawv xim tsis ua hauj lwm kaw tshwm sim.Nyob rau hauv daim ntawv no, tus neeg sau qhia txog cov teeb meem txawv txav xws li kev xav pom ntawm Huizhou 32-2 platform Hnub ci roj turbine generator teeb, sib tham txog daim ntawv thov ntawmkua roj vanish tshem tawm unitnyob rau hauv lub platform chav tsev, thiab muab ib co siv rau cov khoom siv tu cov neeg ua hauj lwm nyob rau hauv muaj feem xyuam rau industries nyob rau hauv kev tswj cov khoom lubricating roj kua roj vanish.
1 Tsim mechanism thiab phom sij ntawm lubricating roj kua roj vanish
1.1 Kev soj ntsuam ntawm lubricating roj zaj duab xis
kua roj vanish yog ib tug polymer, yog oxidation ntawm cov khoom roj, xim los ntawm lub teeb xim av, xim av rau tan, nws tiam ntawm lub ntsiab yog vim li cas muaj peb yam.
(1) Oxidative thiab degradation ntawm cov khoom siv roj: cov khoom siv roj siv hauv chav kawm.Qhov kub thiab txias, dej, hlau, thiab huab cua txhua tus ua kom oxidation, ua kom muaj carboxylic acid, ester, cawv thiab lwm yam khoom oxidation, thiab ntxiv condensation daim ntawv rau hauv polymer: ntxiv rau, amine antioxidant nyob rau hauv cov roj kuj yog yooj yim los ua kua roj vanish.
(2) Cov chaw kub hauv cheeb tsam thiab microcom bustion ua rau cov roj hauv paus lossis cov thermal degradation sai ntawm cov additives los ua cov kua roj vanish, kub lossis siab zog sib txhuam Ib feem ntawm cov hlau saum npoo ntawm qhov kub siab dua (feem ntau xws li bearing bush), ua rau Qhov kub ntawm cov kua dej tiv tauj thaj chaw yog siab heev, ua rau cov kua dej sai sai thermal degradation los ua cov kua roj vanish, thiab yooj yim ua raws li cov khoom sib xyaw ua ke;lubricating roj nyob rau hauv cov ntaub ntawv ntawm ntse compression kuj yog ib qho yooj yim los tsim micro combustion tshwm sim, tsim ib tug me me me me ntawm cov khoom insoluble, txuas mus rau cov hlau nto ua kua roj vanish, piv rau thawj tiam ntawm oxidation degradation, lub thib ob tiam. pleev xim rau daim nyias nyias yuav nrawm dua.
(3) Lub txim hluav taws xob tseem yuav tsim cov kua roj vanish, tshwj xeeb tshaj yog thaum cov roj dhau los ntawm qee qhov kev lim dej kom tsim tau qhov zoo li qub, qhov tshwm sim tawm ntawm cov kua roj vanish yooj yim.
1.2 Kev puas tsuaj ntawm lubricating roj kua roj vanish
Varnish tsub zuj zuj ntawm kev sib txhuam sab saum npoo yuav txo cov roj zaj duab xis sib txawv, kev hloov pauv kub tsis zoo, lubricating roj fluidity deterioration, ua rau kev sib txhuam auxiliary deg kub kom nce siab, kev puas tsuaj loj heev rau qhov chaw;roj turbine yeej ib txwm qhib thiab nres lub xeev ua hauj lwm, qhov kev hloov ntawm cov roj kub yog feem ntau yuav ua rau cov duab ntawm cov kua roj vanish, tsim cov kua roj vanish tau yooj yim ua raws li sophisticated Cheebtsam, xws li hydraulic servo valve, ua rau lub valve thaiv, valve. core daim ntawv cog lus tuag, tswj tsis ua haujlwm thiab txawm tias cov cuab yeej dhia;cov kua roj vanish kuj ua rau cov dej txias txias tsis zoo, cov khoom siv lim dej tsis zoo, cov roj lubrication tsis zoo ua rau lub cev hnyav hnyav thiab cov khoom siv roj nrawm oxidation thiab lwm yam.
2 Varnish tendency index nrhiav kom tau tus qauv
Tam sim no, txoj kev ntsuas roj cov kua roj vanish tendency Performance index yog ASTM D7843 "purifier membrane photometric tsom xam (MPC) nrhiav pom nyob rau hauv kev siv Test method rau xim-insoluble khoom nyob rau hauv chav turbine roj.Cov txiaj ntsig tau tshaj tawm raws li xim Membrane tendency Performance index AE.Lub hauv paus ntsiab lus ntawm txoj kev no yog siv lub tshuab nqus tsev lim tshem tawm cov sludge thiab gelatin los ntawm cov khoom siv roj thiab muab tso rau hauv ib lub purifier daim nyias nyias ntawm lub phaj (purifier membrane aperture 0.45 p, m), siv lub purifier tom qab lub phaj purifier qhuav. Zaj duab xis chromaticity tester los ntsuas nws qhov MPC (AE) qhov tseem ceeb.Lub purifier membrane tau tso rau ntau yam uas koj tau txais.Cov xim tsaus dua, qhov ntau dua cov kua roj vanish nyiam index.Thaum rov ua dua
Kev nce ntxiv ntawm MPC (AE) tus nqi yuav tsum ua rau cov neeg ua haujlwm tswj xyuas cov cuab yeej lossis cov neeg ua haujlwm saib xyuas nws.
3. Daim ntawv thov ntawm cov kua roj vanish tshem tawm roj purifier
3.1 Cov xwm txheej tam sim no ntawm lubricating roj ua ntej siv cov kua roj vanish tshem tawm cov roj purifier
Huizhou 32-2 platform roj turbine generator teeb yog hnub ci T60 chav tsev,
Saib Table 1 rau cov kev ntsuas tshwj xeeb ntawm cov roj lubricating ua ntej siv cov kua roj vanish purifier.

Qhov xaus ntawm lub koom haum kuaj thib peb yog raws li hauv qab no: cov kua roj vanish siab index tus nqi lub rooj ci roj muaj ntau tus naj npawb ntawm cov polar me me molecule insoluble khoom, yooj yim rau kev ua raws li cov hlau ua cov kua roj vanish rau saum npoo, cov kua roj vanish yuav ua rau kev sib txhuam. Qhov nruab nrab kub kom nce thiab ua rau cov cuab yeej tsis ua haujlwm, cov ntsiab lus tsis tshua muaj siab tuaj yeem cuam tshuam rau kev ruaj ntseg thiab kev pabcuam lub neej ntawm qhov cuam tshuam, cov roj tuaj yeem siv txuas ntxiv mus, tab sis yuav tsum muaj kev ua haujlwm siab pom.Siv qhov chaw tshem tawm cov kua roj vanish kom tshem tawm cov polarity ntawm cov roj solubility, nws raug nquahu kom txo lub sijhawm ua piv txwv thiab ua tib zoo saib xyuas kev huv thiab MPC tus nqi thiab ntsuas ntsuas ntsuas.Los ntawm kev soj ntsuam ntawm cov cuab yeej siv, cov roj lubricating tswj lub siab tsis ruaj khov tshwm sim hauv kev ua haujlwm, uas cuam tshuam rau kev ntseeg siab ntawm cov roj lubricating tau npaj thiab cov khoom siv tswj cov kua.
3.2 Txoj Cai thiab kev siv ntawmkua roj vanish tshem tawm unit
Raws li qhov teeb meem ntawm cov kua roj vanish hauv cov roj lubricating, qee lub tuam txhab tau txais kev hloov pauv roj, tab sis cov nyhuv tsis zoo thiab tsis muaj kev tiv thaiv ib puag ncig.Txhawm rau kom ntseeg tau tias lub tshuab hluav taws xob teeb tsa Kev ntseeg tau, txiav txim siab los npaj rau chav tsev tshem tawm cov kua roj vanish thiab pom kev ua haujlwm.
Cov ntsiab cai ntawm ntau tus neeg sawv cev roj purifiers yog ua nyob rau hauv Table 2
