L company's 100,000 m³/h air separation unit air centrifugal compressor imhando yakajairika yecompressor pamusika wazvino, modhi iEBZ45-2+2+2, uye shaft dhayamita i120mm.Iyo centrifugal compressor inoumbwa nemhepo turbine, bhokisi rekumhanyisa-up uye compressor.Iyo shaft yekubatanidza pakati pecompressor, bhokisi rekumhanyisa-up uye turbine yemhepo ndeye diaphragm yekubatanidza, uye kutakura kwemhepo centrifugal compressor inotsvedza inotsvedza, uye kune mashanu anotakura makwenzi akazara..
Iyo centrifugal compressor inoshandisa yakazvimirira mafuta ekupa system.Rudzi rwecompressor lubricating mafuta iN46 mafuta ekuzora.Mafuta ekuzora anogona kupinda pakati pe dhayamita ye shaft uye kutakura kuburikidza nesimba rinotenderera re shaft dhayamita pacharo.
2 Matambudziko mukushanda kwe centrifugal compressors
2.1 Pane matambudziko makuru
Mushure mekugadzirisa kwakazara muna 2019, iyo mhepo centrifugal compressor yemhepo yekuparadzanisa unit yakashanda zvakanaka mukati megore rimwe chete, pasina kutadza kukuru uye kutadza kudiki.Nekudaro, muna Gumiguru 2020, tembiricha yeiyo huru inotsigira gwenzi recentrifugal compressor yakasangana nekukwira kusingaite.Tembiricha yakasvika pahupamhi hwe82.1 madhigirii celsius, ndokuzodonha zvishoma nezvishoma mushure mekusimuka, uye yakagadzikana paanenge 75 degrees Celsius.Iyo centrifugal compressor yakawana tembiricha isina kujairika inokwira kakawanda, uye tembiricha inokwira inosiyana nguva imwe neimwe, ingangoita 80 degrees Celsius.
2.2 Kuongororwa kwemuviri
Mukupindura dambudziko rekukwira kwekushisa kweiyo centrifugal compressor, kuitira kuti ive nechokwadi chekushanda kwakachengeteka kweiyo centrifugal compressor, L kambani yakaparadzanisa uye yakaongorora iyo centrifugal compressor body muna Zvita, uye zvinogona kunyatsoonekwa kuti mune lubrication huru inotsigira tile nzvimbo Oiri yakakwira tembiricha sintering kabhoni deposition phenomenon.Munguva yekuongorora kwekunze kwe centrifugal compressor, huwandu hwemapepa maviri ekutakura akawanikwa aine kabhoni deposits, uye rimwe remabheji ekutakura raive negomba rakanyura ringangoita 10mmX15mm, uye gomba rakadzika rakareba 0.4mm.
3. Ongororo yezvikonzero zvekukwira kusingaite tembiricha yecentrifugal compressor inobereka gwenzi.
Maererano nekuongorora kwevashandi, zvikonzero zvikuru zvekukwira kwekushisa kwe centrifugal compressor inotakura bush ndezvizvi zvinotevera: (1) Hunhu hwemafuta.Kana iyo centrifugal compressor ichimhanya nekumhanya kwakanyanya, tembiricha yakakwira uye yakanyanya kudzvanywa mamiriro inokonzeresa kuchembera kwemafuta ekuzora, izvo zvichave nemhedzisiro yakaipa pakuzorwa kweiyo centrifugal compressor.Zvinoenderana nekuverenga kwenyanzvi, pese painokwira tembiricha negumi madhigirii celsius, kumhanya kwekuchembera kwemafuta ekuzora kunenge kwakapetwa kaviri, saka kana kuita kwemafuta ekuzora kwakashata, kukurumidza kwekuchembera kunokwidziridzwa zvakanyanya pasi pemamiriro ekupisa. .Kuongororwa kwekuita kwemafuta ekuzora kwakawana kuti mazhinji ezviratidzo haana kuzadzisa zvinodiwa [1] (2) Kuwanda kwemafuta akashandiswa.Kana mafuta ekuzora akawandisa akawedzerwa, zvinokonzeresa kugadzika kwekabhoni mumafuta ekuzora akawandisa pasi pemamiriro ekushisa akanyanya, nekuti mafuta ekuzora akawandisa anozokonzera kusakwana kwemafuta kudzoka, uye musanganiswa wemafuta unonetsa kunyungudika uye une viscosity yakakwirira. gara pedyo negwenzi rinotakura , zvichiita kuti kuderedzwa kwekusununguka kwekutakura, kuwedzera kupfeka uye kutakurwa kwebheji yekutakura, iyo ichaita kuti kuwedzere kusingawanzoitiki kwekushisa kwechigadziro chekutakura nekuda kwekuputika kwepamusoro.(3) Kuvhara kusingawanzoitiki.Zvinoenderana nekuferefetwa kwevanyanzvi, svondo risati rasvika tembiricha isati yasimuka yegwenzi rinotakura recentrifugal compressor, pakave nedambudziko rakakura rekudzima mhepo muchirimwa, izvo zvakakonzera kuvharika kweiyo centrifugal compressor.Iko kuvharika kusingawanzo kukonzeresa iyo axial Force uye isina kuenzana centrifugal simba kuwedzera pakarepo, nekudaro kuwedzera basa rekushanda kwegwenzi rinotakura, zvichikonzera kuwedzera kwekushisa kwemafuta ekuzora.
4 Zviyero zvinobudirira zvekukwira kwekushisa kweiyo centrifugal compressor inotakura gwenzi.
Chekutanga pane zvese, zvinodikanwa kuvandudza mhando yemafuta ekuzora kuti ive nechokwadi chekuti maparamendi emafuta ekuzora anogona kusangana neiyo yekutanga mashandiro eiyo centrifugal compressor.Mafuta ekuzora anogona kuvandudzwa nekuwedzera antioxidants, anti-friction agents uye anti-foaming agents kumafuta ekuzora.Kuita, kunogona kuwana mhedzisiro yakanaka, kuderedza kuchembera kwemafuta ekuzora, kuitira kudzivirira kuzora kwe centrifugal compressor inotakura mapadhi kubva mukuderera nekuda kwekukurumidzira kuchembera kwemafuta ekuzora, uye inogona kugadzirisa dambudziko rekukwira kwe tembiricha isina kujairika. kutakura mapedhi [2].
Chechipiri, huwandu hwemafuta ekuzora anoshandiswa hunoda kunyatsodzorwa.Zvinoenderana nemamiriro ekushanda eiyo centrifugal compressor, huwandu hwemafuta ekuzora akawedzerwa hunofanirwa kudzorwa mukati mehumwe hunoenderana.Mafuta ekuzora akawandisa kana mashoma anokonzeresa kuti centrifugal compressor isashande.Naizvozvo, zvinodikanwa kuti uverenge nemazvo chiyero chekushandiswa kwemafuta ekuzora ye centrifugal compressor uye kuzadza yakakwana mafuta ekuzora nenguva.
Uyezve, nekuti iyo nzvimbo yekutsigira yerutsigiro inotakura ye centrifugal compressor inogadzirwa neyakaomarara alloy zvinhu, kumhanya kwekupfeka kunononoka, saka iyo kabhoni dhipoziti pane yekukanda pad inogona kucheneswa neparafini kugadzirisa dambudziko rekabhoni deposit, nekudaro. kupora Iyo yekumusoro kupera kweiyo thrust pad inogona kuwana mhedzisiro yakanaka mushure mekurapwa.Uye zvakare, mukuona dambudziko rekushomeka kwemafuta ekudonhedza maburi mumhete yekutakura, huwandu hwekudzoka kwemafuta huchaderedzwa, izvo zvinokanganisa kudzoka kwemafuta.Iyo nzira yekusimbisa kushushikana pakuvhurwa kwemhete yekutakura inogamuchirwa, uye tekinoroji inodzokorora nzvimbo yekuvhura Kumanikidza, uye kutaurirana nemugadziri, kwakawedzera wedge, kuitira kuti mafuta ekuzora apinde zviri nani pamusoro pegwenzi rinotakura kusvika. gadzira firimu remafuta.
Chekupedzisira, kuti ugadzirise dambudziko iri, maviri ezasi mapedhi mune nyowani inotakura padhi anoshandiswa kukwenya wedge yemafuta, kuwedzera bhegi remafuta, kuwedzera kuchengetwa kwemafuta ekuzora panguva yekushanda kwepedhi, uye kuita kusangana pakati pekutakura. pad uye shaft dhayamita yakawanda yunifomu., kuve nechokwadi chekuti nzvimbo yekubatana pakati pegwenzi rinotakura uye shaft dhayamita inogona kusangana nemhando zvinodiwa.Panguva imwecheteyo, nzira yekucheka inogamuchirwa kuti iparadze tsvina yose iripo kuitira kuti hutano huve hwakakodzera [3].
Mushure mekutora matanho ari pamusoro apa, dambudziko rekukwira kwekushisa kwe centrifugal compressor rakagadziriswa zvakanaka.Mushure mevhiki yekuyedzwa nekuyedzwa, tembiricha yegwenzi rinotakura inogona kudzorwa pakati pe50-60 madhigirii Celsius, uye kukosha kwekudengenyeka kuri mukati meiyo yakatarwa.Mukati, shanduko yekuchinja iri pachena.
mhedziso
Kupfupisa, chinyorwa ichi chinoongorora zvizere zvikonzero zvekukwira kwekushisa kwe centrifugal compressor inotakura makwenzi, uye inoisa pamberi nhanho dzinoshanda, ndichitarisira kuita rimwe basa mukunongedza uye kubatsira mukugadzirwa kweindasitiri yenyika yangu.
