Nzira yekuchenesa zvakadzika EHC system yemagetsi emagetsi?

Steam turbines pamagetsi emagetsi ane electro-hydraulic control (EHC) masisitimu anoshandisa phosphate

ester-based fire-resistant fluid.Mvura iyi inosangana nekudzikira mubasa kuburikidza nehydrolytic, oxidative uye thermal masisitimu ayo anopesvedzerwa nedhizaini dhizaini uye mamiriro ekushanda.Zvakaitika kare zvakaratidza kuti mamiriro emvura isingadziviriri moto musevhisi yakakosha pakuchengetedza chiteshi uye zviremera zvinodzora zvenyukireya saka zvinosanganisira chemistry control yemvura iyi sechikamu cherezinesi rekushandisa chiteshi.

Nekugadzirwa kwakakura uye kushandiswa kwepamusoro-parameter uye mahombe-akawanda mayuniti, EHC oiri inowedzera uye inowanzoshandiswa mumagetsi e-electro-hydraulic control (EHC) masisitimu, uye kutarisisa uye kuyedzwa kwemhando yemafuta EHC kwavewo kwakakosha. chikamu chekutarisa kwemakemikari.EHC high-pressure resistant oil is phosphate ester resistant oil.Seyakagadzirwa hydraulic oiri, mamwe maitiro ayo akasiyana zvachose nemamineral oil.Kuenzaniswa nemafuta emaminerari, EHC yakakwira-kudzvanywa mafuta ine hunhu hwekuoma kupisa, asi ine zvakare yakashata yehupfu hwepamusoro, hurombo hwekupisa kugadzikana uye kugadzikana kwehydrolytic.Nemhaka yeizvi, hazvigoneki kuti mafuta eEHC akashata panguva yekushanda, iyo inoratidzwa sekuwedzera kwehuwandu hweasidhi, kuderera kwekudzivirira, uye kuwedzera kwehuwandu hwemvura.Kuti uve nechokwadi chekushanda kwakajairika kwemafuta eEHC uye kuwedzera hupenyu hwebasa remafuta anorwisa mafuta, kuchengetedza uye kurapwa panguva yekushanda kwakakosha zvakanyanya.

WSD WVD-K20 inonyatso kusanganisa tekinoroji yekuchenesa tekinoroji, DICR ™ yakaoma ion exchange tekinoroji uye WMR yekuomesa firimu dehydration tekinoroji, iyo inogona kunyatso kubvisa uye kudzivirira zvinhu zvine acidic zvinogadzirwa panguva yakajairika yekushanda kweEHC system uye kubvisa varnish.Kuvandudza resistivity yemafuta eEHC uye kuderedza kusvibiswa uye hunyoro hwemafuta anorwisa-oiri.

EHC fluid kucheneswahaina kuganhurirwa kukudzora acidity.Zvakakoshawo kuchengetedza mvura yakachena uye yakaoma kana ichizoshanda zvakanaka uye kupa hupenyu hurefu hwebasa.Mechanical matekiniki saka anodiwa kuzadzisa uye kuchengetedza basa rekurapa resin.Semuyenzaniso, kushatisa resin ne particulate kunogona kuderedza basa rayo uye izvi zvingada kunatsiridzwa kusefa.

Mutengi ndiyo yekutanga purojekiti yemagetsi enyukireya yakabvumidzwa kuvakwa panguva yenyika ye "Eleventh Five-Year Plan".Ndiyo yekutanga purojekiti yeChina yakamisikidzwa uye hombe yemagetsi enyukireya kuisa mayuniti emagetsi enyukireya emamiriyoni mana panguva imwe chete.Ndiyo zvakare yekutanga gwenya remagetsi enyukireya muNortheast China.Hunhu hwetangi reEHC hunopihwa nemutengi EH system idiki, chete 800L.Kana yadeuka, inokonzeresa nyore kuti unit ifambe.Kuti udzivise matambudziko akadai, tangi yemafuta yekubatsira inoda kuwedzerwa kuzadza tangi huru munguva yekukurumidzira uye kuchengetedza iyo tangi huru.Dzivisa njodzi yekugumburwa.

Mutengi akamboshandisa michina yekuchenesa mafuta kubva kunze kwenyika, asi haina kugadzirisa dambudziko chairo.Mushure mekuenzanisa kwakazara kwemafuta ekuchenesa pamusika, mutengi akazoisa mukushandisa WSD WVD-K20 EHC yekuchenesa mafuta muna Chikumi 2020, iyo yaidzora zvirinani zvirimo zveoiri.Iwo mashanu makuru zviratidzo zvechigadzirwa, zvinosanganisira acid kukosha, resistivity, varnish tendency index, kusvibiswa dhigirii, uye hunyoro, zvese zviri mukati meiyo inokwanisa.Yakagadzirisa zvakamboitika mutengi zvinorwadza mapoinzi akadai seanononoka uye anonamira servo valve chiito chinokonzerwa nevarnish.Mutengi achangobva kuvakwa 5 , Unit 6 yakakurudzira kushandiswa kwemafuta akakosha sefa yeWSD EHC mafuta.
