Namhlanje, ngakumbi e-United States apho iicompressor ziguga, iya ixhaphaka into yokubuyisela iicompressor ezindala ngeetywina zegesi ezomileyo.Ngelixa isiphumo sokugqibela sinokuphucula ukuthembeka (ukuphelisa zonke ezongezelelweyoI-OYILE TINQOamacandelo enkqubo ukusuka kwisekethe ihlala iphucula ukuthembeka), kukho izinto ezimbalwa umsebenzisi wokugqibela kufuneka aziqwalasele ngaphambi kokuba enze isigqibo.
Ukususa i-oyile ye-oyile kwi-compressor kwakhona kuphelisa umphumo obalulekileyo wokudambisa ioli kwi-rotor.Ngoko ke, kufuneka siqhube isifundo se-rotor dynamics ukuqinisekisa ukuba isantya esibalulekileyo sichaphazeleka kancinane xa isitywina sisuswa kumatshini.Olu phononongo lwenziwe phambi kokuba kwenziwe naluphi na utshintsho kwitywina lerhasi eyomileyo.
Uninzi lwababoneleli namhlanje bacebisa ukwenza uphononongo lwe-rotor dynamics ngaphambi kokuphucula i-compressor endala kunye nesitywina segesi esomileyo.Nangona kunjalo, ukulandela eli nyathelo kuya kukunceda uphephe iingxaki ezingalindelekanga ngexesha lokuqalisa.
Kwiminyaka yakutshanje, siye sabona le ngxaki kunye nabathengi abanokuthembeka kwe-ATS ngenxa yokufuduka kwegesi yenkqubo engacocwanga ngokusebenzisa i-labyrinth seals okanye ukuvuza kwegesi yenkqubo ngokusebenzisa i-laboratory ephakathi ukuya kwi-atmosphere (ngokusebenzisa ama-second vents).
KuMzobo 1 ubonisa umzobo wenkqubo yegesi yetywina eqhelekileyo.Xa irhasi isetyenziswa kwisitywina sokuqala, kuphela isixa esincinci kakhulu serhasi (engaphantsi kwe-1%) evuzayo kumphezulu wokutywina, kunye nentsalela idlula kwinkqubo ye-labyrinth seal (eboniswe ngombala obomvu).
Okukhona iphezulu isantya serhasi ngokutywinwa kwelabyrinth, kokukhona isahlula igesi yenkqubo engahluzwanga kwisitywina esikhulu.Ukuba oku kuyenzeka, abasebenzisi bokugqibela banokufumana iingxaki ngokufakwa kwimijelo yetywina, okukhokelela kukusilela okanye ukuncamathela komsesane wokutywina.
Ngokufanayo, ukuba isantya sokuhamba kwegesi ephakathi (ngokuqhelekileyo i-nitrogen) kwilebhu ephakathi (eboniswe eluhlaza) iphantsi kakhulu, i-compressor ayiyi kuba nesitywina sesibini se-nitrogen, ngoko ke umsebenzisi wokugqibela ukhetha eso sitywina kuqala.indawo yokukhulula initrogen kwinkqubo yokuphuma kwesibini kuphela!
Sincoma ubuncinci be-30 ft / sec kuzo zombini izitywina ze-labyrinth ngokuphindwe kabini ukukhutshwa okuphezulu (ukuvumela ukunxitywa kwe-labyrinth seal).Oku kuya kuqinisekisa ukwahlukaniswa okufanelekileyo kweegesi zenkqubo ezingafunwayo kwelinye icala le-labyrinth seal.
Enye ingxaki eqhelekileyo isandula ukufunyanwa kwiicompressors ezinezitywina zegesi eyomileyo kukufuduka kweoyile ngetywina eliqhekekileyo.Ukuba ioli ayichithwanga kwi-cavity, ekugqibeleni iya kuzalisa i-groove kwaye ibangele ukungaphumeleli kwentlekele yesitywina sesibini (esinye isihloko sesinye ixesha)..
Isizathu esona sizathu kukuba indawo ye-axial phakathi kwe-oyile endala kunye ne-bearing incinci kakhulu, kwaye i-rotor endala ayinayo inyathelo kwi-shaft phakathi kwe-oyile kunye nokuthwala.Oku kuya kunika indlela yokuba ioli idlule kwisitywina sokuqhawula kunye negumbi lesibini lokukhupha.
Ngoko ke, sincoma kakhulu ukufaka i-oyile deflector kwi-seal bushing (ejikelezayo) ngaphandle kwetywina eliqhekezayo, eliya kuthi liqondise ioli kude ne-seal bore.Ukuba le miqathango mithathu idibene, kunye nepaneli yegesi yokutywina exhotyiswe kakuhle, umsebenzisi wokugqibela uya kufumanisa ukuba ukutywinwa kwegesi eyomileyo kunokusinda ukulungiswa okuninzi.Irhasi eyomileyoitywina yeolisisitywina somatshini esingaqhagamshelwanga esiphuhliswe ngokwesiseko seebheringi zoxinzelelo oluguquguqukayo lwegesi, oluthanjiswa ngefilimu yegesi ngexesha lokusebenza okomileyo.Elitywina lisebenzisa umgaqo wokuguquguquka kolwelo kwaye liphumeze ukusebenza okungadibanisiyo kobuso besiphelo sokutywina ngokuvula umsele oguquguqukayo woxinzelelo kubuso besiphelo sokutywinwa.Ekuqaleni, ukutywinwa kwegesi eyomileyo kwakusetyenziselwa ukuphucula ingxaki yokutywinwa kwe-shaft ye-high-speed centrifugal compressors.Ngenxa yokungaqhagamshelwa kokutywinwa, ukutywinwa kwegesi eyomileyo kuneempawu zokungachaphazeleki kwixabiso le-PV, izinga lokuvuza eliphantsi, ukunxiba ukusebenza kwasimahla, ukusetyenziswa kwamandla aphantsi, ubomi benkonzo ende, ukusebenza kakuhle okuphezulu, ukusebenza okulula nokuthembekileyo, kunye nokuba ukhululekile kungcoliseko lweoyile yolwelo olutywiniweyo.Inethemba elihle lokusetyenziswa kwezixhobo zoxinzelelo oluphezulu, izixhobo ezinesantya esiphezulu, kunye neentlobo ezahlukeneyo zezixhobo zecompressor.
