Electrostatic oiri yekuchenesa inoshandiswa muturbine oiri system
Iyo steam turbine yekuzora mafuta anoshandiswa muutsi turbine lubrication system uye murazvo-resistant hydraulic mafuta anoshandiswa mu hydraulic control system ane zvakaomesesa index zvinodiwa panguva yekushanda kweyuniti, senge viscosity, particle kusvibiswa, mwando, acid value, oxidation kuramba, anti- emulsification, etc. Pakati pavo, dhigirii yekusvibiswa kwechidimbu inonyanya kukosha, sezvo iine hukama nekupfekedzwa kwejecha remhepo remhepo rotor uye mabheji, kushanduka kwemavharuvhu e-solenoid uye servo valves muhurongwa hwekutonga, hunokanganisa zvakananga kushanda. kuchengetedzwa kweiyo steam turbine zvishandiso.
Sezvo dhizaini turbine midziyo inokura yakanangana nehukuru hukuru uye yakakwirira paramita, kuitira kudzikisa kukura kwechimiro cheinjini yemafuta, murazvo usingadziviriri hydraulic oiri inogadzirwa yakanangana nekumanikidza kwakanyanya.Sezvo zvinodikanwa zvekuvimbika kwekushanda kweyuniti zvichiwedzera, zvinodikanwa zvehutsanana hweturbine yekuzora mafuta uye murazvo-inodzivirira hydraulic oiri zviri kuwedzera nekukwira.Kuti uve nechokwadi chekuti indekisi yemhando yemafuta inogara iri mukati meiyo chiyero panguva yekushanda kweyuniti, kusefa kwemafuta epamhepo emafuta ekuzora uye murazvo-inodzivirira hydraulic oiri inodiwa.Naizvozvo, kusarudzwa kwemafuta sefa uye maitiro ayo ekurapa anozokanganisa zvakananga kuchengetedzeka uye kuvimbika kweiyo steam turbine kushanda.
Mhando yemafuta anonatsa
Zvinoenderana nemisimboti yekusefa, oiri yekuchenesa inogona kupatsanurwa kuita mechaniki kusefa, centrifugal kusefa uye electrostatic adsorption kusefa.Mumapurojekiti chaiwo, nzira dzakasiyana-siyana dzekugadzirisa dzinowanzobatanidzwa uye kushandiswa.
1.1 Mechanical oiri yekuchenesa
Iyo mechanical oiri sefa inobata tsvina yemafuta muoiri kuburikidza nemuchina sefa.Iyo filtration effect yakanangana nekurongeka kweiyo mechanical filter.Kurongeka kwesefa kunogona kusvika parizvino kusvika 1μm.Iri rudzi rwemafuta sefa rinoshandiswa zvakanyanya mumagetsi masisitimu.Iyo yakapetwa kaviri sefa yemafuta, mafuta ekudzosa sefa, uye online sefa inowanzo gadziridzwa muoiri yekuzora system ese ari emagetsi mafirita.Huru tsvina muoiri yekuzora system inogona kubviswa ne mechanical oil filter, uye tsvina diki inogona kubviswa ne precision mechanical filter element.
Izvo zvisingabatsiri zvema mechanical oil purifiers ndezvi: iyo yakakwirira yefiltration chaiyo, iyo yakakura inopindirana kuramba, uye mafuta ekupa kudzvinyirira kurasikirwa kwakakura;hupenyu hwesevhisi hwesefa ipfupi, uye iyo sefa chinhu chinoda kuchinjwa kazhinji panguva yebasa.Kushanda zvisina hanya kunogona kukonzera kusvibiswa kwemaitiro.;Haikwanise kusefa hunyoro, zvigadzirwa zvecolloidal uye tsvina idiki pane saizi yepore yesefa mumafuta.Kuti ukunde zvikanganiso zviri pamusoro, mumainjiniya ekushandisa, mafirita emafuta emuchina anowanzo shandiswa pamwe chete nedzimwe nzira dzekuchenesa (senge vacuum dehydration, nezvimwewo) kuti uwane yakanakisa kurapwa maitiro.
1.2 Centrifugal oiri yekuchenesa
Centrifugal filtration tekinoroji inoshandisa centrifuge kuchenesa mafuta mutangi.Nekutenderedza oiri ine zvimedu uye zvimwe zvinosvibisa nekumhanya kwakanyanya, tsvina ine density yakakura kupfuura oiri inokandwa kunze kuti iite chinangwa chekuparadzanisa mafuta akachena.Kubatsira kwayo ndeyokuti inonyanya kushanda pakubvisa mvura yekusununguka uye tsvina huru yezvikamu uye ine simba guru rekugadzirisa.Kukanganisa kwaro ndekwekuti haibatsiri pakubvisa zvimedu zviduku uye haigoni kubvisa mvura isina kusununguka.Centrifugal kusefa mafirita emafuta anoshandiswa zvakanyanya mukurapa mafuta mumagasi emagetsi emagetsi emagetsi, uye anowanzoshandiswa pamwe chete nemakanika ekusefa nzira dzekurapa muutsi turbine yekuzora mafuta masisitimu.Nekuda kwekuti centrifuge inotenderera nekumhanya kukuru, midziyo ine ruzha, ine nharaunda yekushanda isina kunaka, uye yakakura muhukuru uye uremu.
1.3electrostatic oiri yekuchenesa
Electrostatic oil purifier inonyanya kushandisa yakakwira-voltage electrostatic munda inogadzirwa neelectrostatic jenareta kuunza twunhu tunosvibisa muoiri nemaion emagetsi uye kunamatira kune mafiber pasi pekuita kwemunda wemagetsi.Nheyo yacho inoratidzwa mumufananidzo uri pasi apa.Nekuda kwekushandiswa kweiyo adsorption musimboti pachinzvimbo chekupfuura-kuburikidza kusefa, iyo electrostatic oiri yekuchenesa inogona kubata tsvina dzakasiyana nekunaka kwe0.02μm, kusanganisira yakaoma simbi zvinhu, zvinyoro zvinyoro, nezvimwewo, uye inogona kuzvibvisa.
Charge adsorption musimboti dhayagiramu
Zvimiro zve electrostatic oiri purifier:
(1) Kucheneswa kwepamusoro, kurongeka kwesefa kunosvika 0.1μm, kunogona kubvisa sub-micron zvinosvibisa;
(2) Inogona kunyatsobatanidza vacuum system uye coalescing system kuti ikurumidze kubvisa mvura uye gasi;
(3) Iyo yekumhanyisa yekuchenesa inokurumidza, iyo inogona kukurumidza kugadzirisa zvimedu uye kuchenesa nekukurumidza;chiyero chekuyerera chakakura, chinogona kusangana nezvinodiwa zvekutsvaira nekuchenesa;
(4) Kuchenesa system basa.Iyo electrostatic polymerization yekuchenesa tekinoroji haingobvisi tsvina uye zvimedu muoiri, asi zvakare inobvisa zvigadzirwa zvine acidic, inochajiswa colloids, sludge, varnish uye zvimwe zvinhu zvinokuvadza kudzivirira kuzvarwa patsva nekuvandudza pH kukosha kwemafuta., kuderedza mutengo we dielectric kurasikirwa zvinhu uye kukosha kweasidhi, uye kuvandudza zviratidzo zvechigadzirwa chemafuta;
(5) Iine huwandu hwakawanda hwekushandisa uye inogona kushanda zvakajairika kunyangwe mvura iri muoiri ichipfuura mwero.Inogona kushanda mumafuta ane huwandu hwemvura inodarika 20%.

Varnish
2.1 Njodzi dzevarnish
"varnish" inonziwo coke, gum, pendi-yakafanana nezvinhu, elastic oxides, pendi yeganda, nezvimwewo. Iyo insoluble film-like precipitate inogona kunge iri orenji, brown kana dema, uye chibereko chekuora kwemafuta..
Mushure mekunge varnish yaonekwa mu turbine lubricating oiri system, iyo varnish inoumbwa mune inotsvedza inokwanisa kunamatira kune simbi pamusoro, kunyanya pakucheneruka kwebereko, zvichikonzera kuderedzwa kwehushoma hwemafuta firimu ukobvu, kuwedzera kwe yakanyanya mafuta firimu kudzvanywa, uye kuderedzwa kwemutoro wekutakura.Kuwedzera kwekushisa kwemafuta ekuzora kuchava nechakaipa pakushanda kwakachengeteka kwekutakura.
Chiitiko chevarnish uye njodzi dzayo dzakatorwa zvakanyanya muEurope, United States neJapan.United States yakagadzira chiyero chekuona varnish (ASTMD7843-18), uye yakabatanidza iyo varnish tendency index muoiri shanduko yekuongorora indekisi.Nyika yedu yakanyorawo varnish sechinhu chekuedza muGB/T34580-2017, asi parizvino mashoma mashoma emagetsi uye masangano ekutsvagisa anoziva nezvenjodzi dzevarnish.
WSD electrostatic oil purifier inoshanda zvakadzikama uye ine mhedzisiro yakanaka pakubvisa zvidiki uye zvidiki zvimedu (ona inotevera nhamba yeruzivo).Indekisi yemafuta inodzorwa padanho reNAS6 kwenguva yakareba kuti isangane nezvinodiwa zvepa-saiti yekudzora kusvibiswa.Kubva 2017, mutengi akatevedzana kutenga 2 seti yemidziyo yemhando imwe chete.
