Kev siv tshiab ntawm cov kua roj vanish tshem tawm tshuab hauv sola gas turbine generator

3.1 bearing bush kub nce yog vim li cas

3.1.1 Cov roj lubricating siv hauv chav tsev no yog CASTROL PERFECTO X32, uas yog cov roj ntxhia.Thaum qhov kub thiab txias, cov roj lubricating tau yooj yim rau oxidation, thiab cov khoom oxidation sib sau ua ke ntawm qhov chaw ntawm shbush los ua cov kua roj vanish.Los ntawm kev txheeb xyuas qhov Performance index ntawm cov roj khiav ntawm chav tsev, nws pom tau tias cov kua roj vanish siab Performance index siab, thiab cov pa phem kuj siab (saib Table 5).Qhov kev xav tau ntawm cov kua roj vanish yog siab, uas yuav ua rau tsim kev sib txuas thiab sib sau ua ke ntawm cov kabmob hav txwv yeem, yog li txo qhov sib txawv ntawm cov roj zaj duab xis, ua kom muaj kev sib txhuam, thiab ua rau cov neeg pluag cua sov dissipation ntawm cov kabmob bush, nce ntawm axial. kub thiab acceleration ntawm roj oxidation.Nyob rau tib lub sijhawm, vim muaj cov pa phem ntau hauv cov roj, cov kua roj vanish yuav ua raws li lwm cov khoom tsis huv, ua rau kev sib tsoo thiab ua rau cov khoom hnav hnyav dua.(Saib daim duab 3 Flow chart of unit lubrication)

Txhawm rau txheeb xyuas qhov ua rau ntawm cov kabmob bush kub nce, nws yuav yog cov kua roj vanish yog tsim nyob rau hauv cov roj lubricating ntawm chav tsev, thiab cov kua roj vanish thaum kawg yog concentrated nyob rau hauv bearing bush, uas ua rau lub kub hloov pauv thiab nce ntawm bearing bush.

3.1.2Ua rau cov kua roj vanish

* Mineral lubricating roj feem ntau yog tsim los ntawm hydrocarbons, uas yog qhov ruaj khov ntawm chav tsev kub thiab tsis kub.Tab sis yog tias qhov kub thiab txias, qee qhov (txawm tias tus lej tsawg heev) hydrocarbon molecules yuav raug oxidation cov tshuaj tiv thaiv, lwm cov hydrocarbon molecules tseem yuav ua raws li cov tshuaj tiv thaiv saw, uas yog cov yam ntxwv ntawm hydrocarbon saw cov tshuaj tiv thaiv;

* Lubricating roj cov ntaub ntawv soluble kua roj vanish nyob rau hauv qhov kub thiab txias cheeb tsam.Nyob rau hauv cov txheej txheem ntawm cov roj ntws los ntawm qhov kub thiab txias mus rau qhov kub tsis tshua muaj, qhov kub thiab txias yuav ua rau txo qis ntawm solubility, thiab cov kua roj vanish yog precipitate los ntawm cov roj lubricating thiab pib tso nyiaj;

* Deposition ntawm cov kua roj vanish tshwm sim.Tom qab tsim cov kua roj vanish, cov sediment pib condense thiab tsim cov sediment yuav nyiam tso rau ntawm cov hlau kub, uas ua rau lub hav txwv yeem kub nce ceev rov qab roj kub kuj yuav maj mam nce;

* Cov kub hloov pauv uas yuav tshwm sim los ntawm lwm yam ib puag ncig lossis teeb meem txhaum cai ntawm chav tsev.

3.2 Kev ntsuas los daws qhov teeb meem ntawm cov kabmob bush kub nce

3.2.1 Tsa lub lubricating roj siab los ntawm 0.23 Mpa mus rau 0.245 Mpa los txhim kho lub lubrication tshav kub hloov efficiency thiab alleviate lub qeeb rising trend ntawm bearing bush kub.

3.2.2 Hloov cov zawv zawg cov roj txias nrog cov hluav taws xob qis qis nrog lub tshuab hluav taws xob hauv tsev tshiab, thiab cov roj zawv zawg qhov kub thiab txias yog qhov ruaj khov ntawm 60 ℃ txog 50 ℃ rau lub sijhawm ntev.

3.2.3 Lub hauv paus ntsiab lus ua haujlwm ntawm electrostatic adsorption technology —— tshem tawm cov kua roj vanish (saib daim duab 4)

Electrostatic purification yog siv lub voj voog hluav taws xob zoo li qub, ua rau cov roj pa phem qhia pom qhov zoo thiab qhov tsis zoo ntawm hluav taws xob raws li qhov zoo thiab qhov tsis zoo hluav taws xob nyob rau hauv qhov kev txiav txim ntawm qhov tsis zoo thiab qhov zoo electrode kev taw qhia, nruab nrab hais squeezed los ntawm tus nqi hais txaus, thaum kawg tag nrho cov hais. adsorption ntawm lub collector, tshem tawm tag nrho cov pa phem nyob rau hauv cov roj, nrog electrostatic roj hais ntws, lub tank, yeeb nkab phab ntsa thiab Cheebtsam ntawm cov av nkos ntawm tag nrho cov impurities, oxide yaig adsorption tawm, lub active tshem tawm qhov system nto nplaum av nplaum thiab nplaum av. , ua si lub luag haujlwm ntawm kev tu lub cev.

3.2.4 Lub hauv paus ntsiab lus ua haujlwm ntawm ion resin adsorption technology —— Tshem tawm cov kua roj vanish yaj

Cov ion txauv resin DICR ™ tuaj yeem tshem tawm cov dej tsis huv hauv cov roj turbine, ua kom cov ntsuas MPC txo qis, vim tias feem ntau ntawm cov turbines yog soluble thaum lub sijhawm ua haujlwm, thiab tsuas yog saturated cov khoom no yuav tsim los nag, cov khoom siv hluav taws xob tsis tuaj yeem tshem tawm cov khoom los ntawm cov khoom no. lub xeev yaj.

Kev sib xyaw ntawm electrostatic adsorption thiab resin thev naus laus zis tuaj yeem tsis tsuas yog tshem tawm cov kua roj vanish, tab sis kuj tshem tawm cov kua roj vanish yaj.
