Abstract: Ongorora zvinokonzeresa kubereka tembiricha yegwenzi yeaviri peturu gasi turbine jenareta, isa pamberi pemhinduro dzakananga, tenzi mapoinzi enjodzi uye mashandiro ekudzivirira matanho.
Equipment overview
BZ 25-1 / S Oilfield (central Bohai Sea) yeCNOOC (China) Co., LTD.Tianjin Bazi (FPSO) ine ina TITAN130 dual-fuel gasi turbine jenareta seti inogadzirwa neSOLAR.Iyo turbine jenareta seti inosanganisira gasi turbine injini, deceleration giya mudziyo, jenareta, control panel, chiridzwa panel, common base, sound insulation cover uye ebetsero hurongwa, etc. Kana chikwata chinoshandisa mafuta akasiyana, kukura kwayo kwekutakura kwakasiyanawo. (Ona Chikamu cheMufananidzo 1)
Iyo mambure ekuburitsa simba returbine i13500kW uye kumhanya i11220rpm, uye simba rekubuda rejenareta rakagadziriswa i12500 kW pasi pe40 ℃ mamiriro ekunze.Mhepo yejenereta ndeye 6300 V, 50 Hz, 3 ph, simba re 0.8 PF;iyo unit yakarerekera cushion inotakura yekukanda kutakura, shaft dhayamita inotakura, uye inoderedza ine Giredhi 3 mapuraneti giya.Imwe neimwe inotakura mafuta inotora nzira yekumanikidza yekuzora yepakati pekupa mafuta.
Ina TITAN130 mbiri-mafuta gasi turbine jenareta seti inogona kugonesa iyo yese mafuta munda, uye kune ina tsvina yekupisa kupisa michina.Iko kupisa kwepakati pemafuta kunopisa neyakakura tembiricha flue gasi inogadzirwa neiyo turbine.Iko kushanda kwakagadzikana uye kwakachengeteka kweina TITAN130 dual-fuel gasi turbine jenareta seti kwakakosha.

Matambudziko aripo neyuniti
Muna Kubvumbi 2018, zvakaonekwa kuti tembiricha yegwenzi rinotakura remayuniti mana yakachinja, uye mamwe tembiricha mapoinzi aisakwanisa kudzokera kune yekutanga kukosha kwekushanda mushure mekunge tembiricha yawedzera.Imwe turbine inobereka (inotakura gwenzi) yakasvika tembiricha kubva pa108℃ uye yakaratidza kukwira kumusoro, nepo mamwe mayuniti matatu airatidzawo kukwira kumusoro.
Chikonzero chekuongorora uye matanho ekurapa
3.1 inobereka tembiricha yegwenzi inokwira chikonzero
3.1.1 Mafuta ekuzora anoshandiswa muchikwata ichi CASTROL PERFECTO X32, inova mineral oil.Kana tembiricha yakakwira, mafuta ekuzora ari nyore kuita oxidation, uye oxidation zvigadzirwa zvinoungana pamusoro peshbush kuti igadzire varnish.Nekuona index yemafuta anomhanya echikwata, inowanikwa kuti varnish tendency index yakakwirira, uye dhigirii yekusvibisa zvakare yakakwirira (ona Tafura 5).Iyo tendency index yevarnish yakakwirira, iyo inogona kukonzera kuumbwa kwekunamatira uye kuunganidza pagwenzi rinotakura, nokudaro kuderedza gaka remafuta firimu, kuwedzera kukweshana, uye kutungamirira kuhurombo husina kunaka hwekupisa kwegwenzi rinotakura, kukwira kweaxial. tembiricha uye kukurumidza kwemafuta oxidation.Panguva imwecheteyo, nekuda kwekusvibiswa kwepamusoro mumafuta, varnish inonamatira kune zvimwe zvimedu zvakasvibiswa, zvichiita kukuya kwekuita uye kuwedzeredza kupfeka kwemidziyo.

Mufananidzo 3 Inoyerera chati ye unit lubrication
Kuongorora chikonzero chekukwira kwekushisa kwegwenzi rinotakura, zvingave kuti varnish inogadzirwa mumafuta ekuzora eyuniti, uye varnish inozopedzisira yaiswa pagwenzi rinotakura, zvichikonzera kushanduka kwekushisa uye kukwira kwegwenzi rinotakura.
* Mineral lubricating oil inonyanya kuumbwa nemahydrocarbons, ayo akadzikama patembiricha yepakamuri uye tembiricha yakaderera.Asi kana muchiitiko chekushisa kwepamusoro, mamwe (kunyange kana nhamba yacho iduku zvikuru) mamorekuru ehydrocarbon achapinda oxidation reaction, mamwe mamorekuru ehydrocarbon anozoteverawo chain reaction, inova hunhu hwehydrocarbon chain reaction;
* Mafuta ekuzora anoumba varnish inonyungudika munzvimbo yepamusoro tembiricha uye nzvimbo yekumanikidza.Mukuita kwemafuta ekuyerera kubva kunzvimbo yepamusoro yekupisa kusvika kune yakaderera tembiricha, kuderera kwekushisa kunotungamirira kukudzikira kwekunyungudika, uye mavarnish particles anowedzera kubva mumafuta ekuzora uye anotanga kuisa;
* Kuiswa kwevarnish kunoitika.Mushure mekugadzirwa kwevarnish particles, sediment inotanga kunyunguduka uye kuumba sediment ichave yakanyatsoiswa panzvimbo inopisa yesimbi, zvichiita kuti kupisa kwegwenzi kusimuke nokukurumidza kumashure kwekushisa kwemafuta kunowedzerawo zvishoma nezvishoma;
* Kuchinja kwekushisa kunogona kukonzerwa nezvimwe zvakatipoteredza kana matambudziko eyuniti.
3.2 Matanho ekugadzirisa dambudziko rekuwedzera tembiricha yegwenzi rinotakura
3.2.1 Simudza mafuta ekuzora kubva pa 0.23 Mpa kusvika pa 0.245 Mpa kuti uvandudze kupisa kwemafuta ekupisa uye kuderedza kunonoka kukwira kwekushisa kwegwenzi rinotakura.
3.2.2 Tsiva inotsvedza yemafuta inotonhorera nekuderera kuchembera kwekushisa kwekufambisa kushanda neitsva yepamba yakananga dhiraivha inotonhorera, uye inotsvedza tembiricha yemafuta inotsvedza yakagadzikana kubva pa60 ℃ kusvika pa50 ℃ kwenguva yakareba.
3.2.3 Kushanda musimboti we electrostatic adsorption technology —— kubviswa kwevarnish yakanaya (ona Mufananidzo 4)
Electrostatic purification iko kushandiswa kwedenderedzwa yakakwira voltage static field, ita kuti mafuta ekusvibisa zvimedu aratidze zvakanaka uye zvisina kunaka magetsi zvichiteerana, zvakanaka uye zvisina kunaka zvimedu zvemagetsi zviri pasi pekuita kweasina kunaka uye yakanaka electrode direction, kwazvakarerekera zvakasvinwa nechaji zvimedu zvinoyerera, pakupedzisira zvese zvimedu. adsorption pamuunganidzi, bvisa zvachose zvinosvibisa muoiri, ine electrostatic mafuta zvimedu zvinoyerera, tangi, pombi madziro uye zvikamu zvedhaka pane zvese zvitsvina, oxide erosion adsorption kunze, iyo inoshanda inobvisa system inonamira dhaka uye inonamira tsvina. , tamba basa rekuchenesa system.

3.2.4 Kushanda musimboti weion resin adsorption tekinoroji —— Bvisa varnish yakanyungudika
Iyo ion inotsinhanisa resin DICR ™ inogona kubvisa zvinonyungudika mumafuta eturbine, ichive nechokwadi chekudzikira kweMPC zviratidzo, nekuti mazhinji ematurbine anonyungudika panguva yekushanda, uye anongozara zvigadzirwa izvi zvinogadzira kunaya, electrostatic michina haigone kubvisa izvi by-zvigadzirwa mu iyo yakanyungudika.
Iko kusanganiswa kwe electrostatic adsorption uye resin tekinoroji haingogone chete kubvisa yakamiswa varnish, asi zvakare kubvisa yakanyungudika varnish chigadzirwa.

3.3 Mhedzisiro yekubvisa varnish
Musi waZvita 14, 2019, WVD modhi yevarnish mafuta sefa yakaiswa uye kushanda.Pasi pechiyero chakakwana chekutsiva gasi turbine oiri inotonhorera muna Nyamavhuvhu 20,2020, tembiricha yeturbine inobereka (gwenzi) yakadzikira kubva pa108 ℃ kusvika panosvika 90 ℃ (ona Mufananidzo 6 wetembiricha yekucheneswa kumashure (gwenzi)).Muvara wemafuta unovandudzwa zvakanyanya (Mufananidzo 7 kuenzanisa kwemafuta pamberi uye mushure mekucheneswa).Kuburikidza nekuongorora uye data yekuongorora kwekunze, iyo tendency index yevarnish yemafuta yakaderedzwa kubva ku42.4 kusvika ku4.5, chiyero chekusvibiswa chakaderedzwa kubva kuNAS 9 kusvika ku6, uye iyo acid value index yakaderedzwa kubva ku0.17 kusvika ku0.07. (Ona Tafura 6 Test uye kuongororwa mhedzisiro yemafuta mushure mekusefa sefa)

Kubatsirwa kwehupfumi kwakagadzirwa
Kuburikidza nekuisa uye kushanda kweWVD varnish yekubvisa unit, zvinogadzirisa kugadzirisa gasi turbine iyo inotakura tembiricha inokwira, dzivirira kukuvadzwa kwakanyanya kunokonzerwa nekukuvara kwekutakura uye kutenderera kwekuisa chisimbiso kurasikirwa kunokonzerwa neasara zvikamu, kuderedza kuchengetedza kunotakura kurasikirwa mu5 miriyoni RMB yekumusoro, uye kuronga kwekugadzirisa nguva yakareba, hapana standby unit panzvimbo yekugadzira, inokonzeresa kukanganisa kwakanyanya pane yakachengeteka uye yakagadzikana kugadzirwa.
Iyo unit inoda kuzadza madhiramu makumi maviri emafuta / unit.Mushure mekusefa firimu rekubvisa pendi, oiri inosvika zvizere kune inokodzera index, ichichengetedza mutengo wekutsiva mafuta ungangoita mazana mana ezviuru RMB.
Mhedziso
Nekuda kweiyo tembiricha yenguva refu, kumanikidza kwakanyanya uye kukurumidza kweiyo lubrication system yeyuniti hombe, iyo oxidation yemafuta inomhanyisa inomhanyisa, iyo varnish index inowedzera, uye zvirimo zvegelatin zvinowedzera.Kuunganidzwa kwetsvina yakapfava mune yakakura unit system inokanganisa kurongeka kweiyo speed regulation system uye yakajairika mashandiro eyuniti, izvo zviri nyore kutungamira kukuchinja kweiyo unit kana kunyange kuvharika kusingarongwi.Iyo varnish glue yakaiswa pamusoro pe gwenzi re shaft ichaitawo kuwedzera kwekushisa kweshaft bush, uye kunamatira kwevarnish uye yakasimba particles kuchawedzerawo kupera uye kubvarura kwemidziyo.WVD varnish yekubvisa unit inogona kuenderera mberi nekuvandudza kunaka kwemafuta ekuzora eyuniti, kuve nechokwadi chekushanda kwakadzikama kutenderera kwemayuniti makuru, kurebesa kutenderera kwesevhisi yemafuta ekuzora, kugadzirisa nharaunda yekushanda kwehurongwa, kuderedza mutengo wekutenga kwemafuta ekuzora.
