Namuhla, ikakhulukazi e-United States lapho ama-compressor eseguga, kuya ngokuya kuvame ukubuyisela ama-compressor amadala ngezivalo zegesi ezomile.Ngenkathi umphumela ungase ube ukwethembeka okuthuthukisiwe (ukuqeda konke okungeziweAMAFUTHA SEALizingxenye zesistimu ezivela kumjikelezo njalo zithuthukisa ukwethembeka), kunezinto ezimbalwa umsebenzisi wokugcina okufanele azicabangele ngaphambi kokwenza isinqumo.
Ukukhipha uphawu lwamafutha ku-compressor futhi kuqeda umphumela obalulekile wokudambisa amafutha ku-rotor.Ngakho-ke, sidinga ukwenza ucwaningo lwe-rotor dynamics ukuze siqinisekise ukuthi isivinini esibucayi sithinteka kancane lapho uphawu lususwa emshinini.Lolu cwaningo lwenziwa ngaphambi kokuthi kwenziwe izinguquko ku-dry gas seal.
Abahlinzeki abaningi namuhla batusa ukwenza ucwaningo lwe-rotor dynamics ngaphambi kokuthuthukisa i-compressor endala ngesivalo segesi esomile.Nokho, ukulandela lesi sinyathelo kuzokusiza ugweme izinkinga ezingalindelekile ngesikhathi sokuqalisa.
Eminyakeni yamuva nje, siye sabona le nkinga kumakhasimende abe nokuthembeka okuncane kwe-ATS ngenxa yokufuduka kwegesi yenqubo engahlungiwe ngokusebenzisa izimpawu ze-labyrinth zenqubo noma ukuvuza kwegesi yenqubo ngokusebenzisa ilabhorethri ephakathi ukuya emkhathini (ngokusebenzisa izintuba zesibili).
Emfanekisweni 1 ubonisa umdwebo ojwayelekile wesistimu yegesi yophawu.Lapho igesi ifakwa uphawu lokuqala, inani elincane kakhulu legesi (elingaphansi kuka-1%) elivuzayo endaweni yophawu, bese kuthi ingxenye esele idlule ohlelweni lwe-labyrinth seal (ekhonjiswe ngokubomvu).
Lapho inyuka isivinini segesi ngophawu lwe-labyrinth, yilapho ihlukanisa khona igesi yenqubo engahlungiwe esigxivizweni esikhulu.Uma lokhu kwenzeka, abasebenzisi bokugcina bangase babe nezinkinga ngokufakwa kwemali emigodini ye-seal, okuholela ekwehlulekeni noma ukunamathela kwendandatho yophawu.
Ngokufanayo, uma izinga lokugeleza kwegesi emaphakathi (ngokuvamile i-nitrogen) elebhu emaphakathi (eboniswe ngohlaza) liphansi kakhulu, i-compressor ngeke ibe nophawu lwesibili olunothe nge-nitrogen, ngakho umsebenzisi wokugcina ukhetha lolo phawu kuqala.indawo yokukhulula i-nitrogen ohlelweni lwe-exhaust yesibili kuphela!
Sincoma ubuncane obungu-30 ft/isekhondi kuzo zombili izigxivizo ze-labyrinth endaweni ephindwe kabili yokuvunyelwa (ukuvumela ukuguga kwe-labyrinth seal).Lokhu kuzoqinisekisa ukuhlukaniswa okufanele kwamagesi enqubo engadingeki ngakolunye uhlangothi lwe-labyrinth seal.
Enye inkinga evamile esanda kutholwa kuma-compressor afakwe izigxivizo zegesi eyomile ukufuduka kukawoyela ngokusebenzisa uphawu olunqamukayo.Uma amafutha engakhishwa emgodini, ekugcineni azogcwalisa i-groove futhi abangele ukwehluleka okuyinhlekelele kophawu lwesibili (esinye isihloko kwesinye isikhathi)..
Isizathu esiyinhloko ukuthi isikhala se-axial phakathi kwesigxivizo samafutha esidala kanye nokuthwala sincane kakhulu, futhi i-rotor endala ngokuvamile ayinayo isinyathelo ku-shaft phakathi kwe-oil seal kanye ne-bearing.Lokhu kuzohlinzeka indlela yokuthi uwoyela udlule esigxivini sokuqhekeka futhi ungene egumbini lokudonsa lesibili.
Ngakho-ke, sincoma ngokuqinile ukufaka i-deflector kawoyela ku-seal bushing (ejikelezayo) ngaphandle kwe-rupture seal, ezoqondisa amafutha kude ne-rupture seal bore.Uma lezi zimo ezintathu zifinyelelwa, kanye nephaneli yegesi yokuvala efakwe kahle, umsebenzisi wokugcina uzothola ukuthi ukuvala igesi eyomile kungasinda ekulungiseni okuningi.Igesi eyomileuwoyela uphawuiwuphawu lwemishini olungathinteki olwakhiwe ngesisekelo se-gas dynamic pressure bearings, egcotshwa ngefilimu yegesi ngesikhathi sokusebenza okomile.Lolu phawu lisebenzisa umgomo we-fluid dynamics futhi lufinyelela ukusebenza okungathinteki kobuso bokuphela kokuvala ngokuvula umsele wokucindezela oguquguqukayo ebusweni bokuphela kokuvala.Ekuqaleni, ukuvala uphawu kwegesi eyomile kwakusetshenziselwa kakhulu ukuthuthukisa inkinga yokuvala shaft yama-compressor we-centrifugal anesivinini esikhulu.Ngenxa yokusebenza okungaxhunywanga kokubekwa uphawu, ukuvala uphawu kwegesi eyomile kunezici zokuthintwa inani le-PV, izinga lokuvuza eliphansi, ukugqoka kwamahhala, ukusetshenziswa kwamandla okuphansi, impilo ende yesevisi, ukusebenza kahle okuphezulu, ukusebenza okulula nokuthembekile, nokuba ngaphandle kokungcoliswa kwamafutha oketshezi oluvalekile.Inethuba elihle lokusetshenziswa kumishini enengcindezi ephezulu, imishini enesivinini esikhulu, kanye nezinhlobo ezahlukahlukene zemishini yokucindezela.
