Nhasi, kunyanya kuUnited States uko macompressor ari kuchembera, zvave kuwedzera kuwanda kudzoreredza ekare macompressor ane yakaoma gasi zvisimbiso.Nepo mhedzisiro inogona kuvandudzwa kuvimbika (kubvisa zvese zvekuwedzeraMAFUTA CHISINDIROzvikamu zvehurongwa kubva kudunhu nguva dzose inovandudza kuvimbika), pane zvinhu zvishoma izvo mushandisi wekupedzisira anofanira kufunga nezvazvo asati aita sarudzo.
Kubvisa chisimbiso chemafuta kubva kune compressor kunobvisawo kukosha kwakadzika kwemafuta pane rotor.Naizvozvo, isu tinofanirwa kuita chidzidzo che rotor dynamics kuti tive nechokwadi chekuti kukurumidza kwakakosha kunokanganisa zvishoma kana chisimbiso chabviswa pamushini.Ichi chidzidzo chakaitwa kusati kwaitwa shanduko kune yakaoma gasi chisimbiso.
Vazhinji vatengesi nhasi vanokurudzira kuita rotor dynamics kudzidza usati wavandudza yakare compressor ine yakaoma gasi chisimbiso.Zvisinei, kutevera danho iri kuchakubatsira kudzivisa matambudziko asingatarisirwi panguva yekutanga.
Mumakore achangopfuura, takaona dambudziko iri nevatengi vanga vasina kuvimbika kweATS nekuda kwekufamba kwegasi risina kusefa kuburikidza nemaitiro labyrinth zvisimbiso kana kuvuza kwegasi rekuita kuburikidza nerabhoritari yepakati kuenda kumhepo (kuburikidza nemagetsi echipiri).
Mumufananidzo 1 inoratidza yakajairika chisimbiso gasi system dhizaini.Kana gasi rinoiswa pachisimbiso chekutanga, ishoma chete gasi (risingasviki 1%) rinodonha nepakati pechisimbiso, uye inosara ichipfuura nekuita labyrinth seal (inotaridzwa mutsvuku).
Iyo yakakwira kukurumidza kwegasi kuburikidza nechisimbiso chelabyrinth, ndipo painoparadzanisa gasi risina kusefa kubva pachisimbiso chikuru.Kana izvi zvikaitika, vashandisi vekupedzisira vanogona kusangana nematambudziko nemadhipoziti mumagirodhi echisimbiso, zvichikonzera kutadza kana kusimba kwechisimbiso mhete.
Saizvozvowo, kana kuyerera kwegasi repakati (kazhinji nitrogen) kuburikidza nerabhu yepakati (inoratidzwa mugirini) yakanyanya kuderera, compressor haizove nenitrogen-inopfuma yechipiri chisimbiso, saka mushandisi wekupedzisira anosarudza chisimbiso ichocho kutanga.nzvimbo yekuburitsa nitrogen mune yechipiri exhaust system chete!
Isu tinokurudzira isingaite 30 ft/sec kune ese ari maviri labyrinth zvisimbiso zvakapetwa kaviri kubvumidzwa kwepamusoro (kubvumidza kupfeka labyrinth seal).Izvi zvinovimbisa kuparadzaniswa kwakakodzera kwemagasi egasi kune rumwe rutivi rwelabyrinth chisimbiso.
Rimwe dambudziko rinowanzo wanikwa munguva pfupi yapfuura mumacompressor ane zvisimbiso zvegasi rakaoma kutama kwemafuta kuburikidza nechisimbiso chinoputsika.Kana mafuta asina kudonhedzwa kubva mugomba, anozopedzisira azadza groove uye kukonzera njodzi kutadza kwechipiri chisimbiso (imwe musoro kune imwe nguva)..
Chikonzero chikuru ndechokuti nzvimbo yeaxial pakati pechisimbiso chekare chemafuta uye kutakura iduku zvikuru, uye rotor yekare kazhinji haina nhanho pane shaft pakati pechisimbiso chemafuta uye kutakura.Izvi zvichapa nzira yemafuta kuti apfuure nepakati pechisimbiso chinoputika uye kupinda mukamuri yechipiri yekudonha.
Nokudaro, isu tinokurudzira zvakasimba kuisa mafuta deflector pane (inotenderera) chisimbiso bushing kunze kwechisimbiso chinoputika, icho chichatungamirira mafuta kubva pakuputika kwechisimbiso.Kana aya matatu mamiriro akazadzikiswa, pamwe chete neyakashongedzerwa sealing gasi pani, mushandisi wekupedzisira achaona kuti yakaoma gasi kuvhara kunogona kupona kugadziridzwa kwakawanda.Gasi rakaomachisimbiso chemafutais a non-contact mechanical seal yakagadzirwa pahwaro hwegasi dynamic pressure bearings, iyo inozorwa negasi firimu panguva yakaoma kushanda.Ichi chisimbiso chinoshandisa musimboti wemagetsi emagetsi uye chinowana kusabata-bata kwechisimbiso chekupedzisira kumeso nekuvhura ine simba rinomanikidza groove pachiso chekuvharisa.Pakutanga, kuvharwa kwegasi kwakaoma kwainyanya kushandiswa kugadzirisa dambudziko rekuvharisa shaft yeyakakwira-kumhanya centrifugal compressors.Nekuda kwekusabatika kwechisimbiso chekuisa chisimbiso, gasi rakaoma kuvharika rine hunhu hwekusakanganiswa nePV kukosha, yakaderera leakage rate, kupfeka mahara kushanda, kuderera kwesimba rekushandisa, hupenyu hurefu hwebasa, kushanda kwepamusoro, kushanda kuri nyore uye kwakavimbika, uye kuve. isina kusvibiswa kwemafuta emvura yakavharwa.Iyo ine tarisiro yakanaka yekushandisa mune yakakwira-kumanikidza michina, yakakwirira-kumhanya michina, uye akasiyana marudzi ecompressor michina.
