Ubomi benkonzo yee-compressors ze-hydrogen refueling station buchaphazeleka zizinto ezahlukeneyo. Ngokubanzi, ubomi benkonzo yazo bumalunga neminyaka eli-10-20, kodwa imeko ethile inokwahluka ngenxa yezi zinto zilandelayo:
Enye, uhlobo lwesiguquli kunye noyilo
1. I-compressor ephinda-phindanayo
Olu hlobo lwecompressor lucinezela igesi yehydrogen ngokusebenzisa intshukumo yepiston ejikelezayo ngaphakathi kwesilinda. Iimpawu zayo zoyilo ziyenza ibe nzima ngokwesakhiwo kwaye ineendawo ezininzi ezihambayo. Ngokubanzi, ukuba igcinwe kakuhle, ubomi benkonzo yeecompressor ezijikelezayo bunokuba malunga neminyaka eli-10-15. Umzekelo, ezinye iicompressor ezijikelezayo ezicwangcisiweyo kwangaphambili zinokuba nobomi benkonzo obuphantse bube yiminyaka eli-10 ngenxa yemida yetekhnoloji kunye nezinto eziphathekayo; Ubomi benkonzo yeecompressor zanamhlanje ezijikelezayo ezisebenzisa izixhobo eziphambili kunye noyilo olulungisiweyo bunokwandiswa ukuya kwiminyaka eli-15.
2. Isixinizeli se-centrifugal
Ii-compressor ze-centrifugal ziyakhawulezisa kwaye zicinezele igesi ye-hydrogen ngokusebenzisa ii-impellers ezijikelezayo ngesantya esiphezulu. Ulwakhiwo lwayo lulula, luneendawo ezimbalwa ezihambayo, kwaye isebenza ngokuzinzileyo phantsi kweemeko zokusebenza ezifanelekileyo. Ngexesha lokusetyenziswa okuqhelekileyo, ubomi benkonzo yee-compressor ze-centrifugal bunokufikelela kwiminyaka eli-15-20. Ingakumbi kwii-compressor ze-centrifugal eziphezulu ezisetyenziswa kwezinye izikhululo ezinkulu ze-hydrogen, xa zigcinwa kakuhle, ubomi benkonzo yazo bunokuba bude.
Ezimbini, iimeko zokusebenza kunye neparameters zokusebenza
1. Uxinzelelo kunye nobushushu
Uxinzelelo olusebenzayo kunye nobushushu beecompressors zesitishi sokufuyela ihydrogen zinempembelelo enkulu kubomi bazo benkonzo. Uxinzelelo olusebenzayo lwecompressor yesitishi sokufuyela ihydrogen eqhelekileyo luphakathi kwe-35-90MPa. Ukuba icompressor isebenza kufutshane nomda woxinzelelo oluphezulu ixesha elide, iya kunyusa ukuguguleka kwecandelo kunye nokudinwa, ngaloo ndlela inciphise ubomi bayo benkonzo. Umzekelo, xa uxinzelelo olusebenzayo lugcinwa luhlala lumalunga ne-90MPa, ubomi benkonzo yecompressor bunokuncipha ngeminyaka emi-2-3 xa kuthelekiswa nokusebenza malunga ne-60MPa.
Ngokuphathelele ubushushu, i-compressor ivelisa ubushushu ngexesha lokusebenza, kwaye ubushushu obuphezulu kakhulu bunokuchaphazela ukusebenza kwezixhobo kunye namandla ezixhobo. Phantsi kweemeko eziqhelekileyo, ubushushu bokusebenza kwe-compressor kufuneka bulawulwe ngaphakathi koluhlu oluthile, olufana nokungadluli kwi-80-100 ℃. Ukuba ubushushu budlula olu luhlu ixesha elide, bunokubangela iingxaki ezifana nokuguga kwezivali kunye nokusebenza okuphantsi kweoyile yokuthambisa, okuya kunciphisa ubomi benkonzo ye-compressor.
2. Ukuhamba komoya kunye nesantya somthwalo
Izinga lokuhamba kwehydrogen limisela imeko yomthwalo wecompressor. Ukuba icompressor isebenza ngamanani aphezulu okuhamba kunye namazinga aphezulu omthwalo (njengokudlula i-80% yezinga lomthwalo woyilo) ixesha elide, izinto ezibalulekileyo ezifana nemoto, i-impeller (yeecompressors ze-centrifugal), okanye i-piston (yeecompressors ezibuyiselanayo) ngaphakathi ziya kuba phantsi koxinzelelo olukhulu, okukhawulezisa ukuguguleka kwecandelo kunye nokuguga. Ngokwahlukileyo koko, ukuba izinga lomthwalo liphantsi kakhulu, icompressor inokufumana ukusebenza okungazinzi kwaye ibe nemiphumo emibi kubomi bayo benkonzo. Ngokubanzi, kufanelekile ukulawula izinga lomthwalo wecompressor phakathi kwe-60% kunye ne-80%, nto leyo enokwandisa ubomi bayo benkonzo ngelixa iqinisekisa ukusebenza kakuhle.
Isithathu, imeko yoLondolozo kunye nokugcinwa
1. Ukugcinwa kwemihla ngemihla
Ukuhlolwa rhoqo, ukucoca, ukuthambisa, kunye neminye imisebenzi yokulungisa rhoqo iicompressor kubalulekile ekwandiseni ubomi bazo benkonzo.
Umzekelo, ukutshintsha rhoqo ioyile yokuthambisa kunye nezitywini kunokuthintela ngempumelelo ukuguguleka nokuvuza kwezixhobo. Ngokuqhelekileyo kucetyiswa ukuba kutshintshwe ioyile yokuthambisa rhoqo emva kweeyure ezingama-3000-5000, kwaye kutshintshwe izitywini rhoqo emva kweminyaka eli-1-2 ngokwemeko yazo yokuguguleka.
Ukucoca indawo yokungena kunye neyokuphuma kwecompressor ukuthintela ukungcola ukuba kungangeni ngaphakathi nako kuyinxalenye ebalulekileyo yolondolozo lwemihla ngemihla.
Ukuba isihluzi sokungenisa umoya asicocwanga ngexesha elifanelekileyo, uthuli kunye nokungcola kunokungena kwi-compressor, nto leyo ekhokelela ekugugeni okukhulu kwecandelo kwaye mhlawumbi kunciphise ubomi benkonzo ye-compressor ngeminyaka eli-1-2.
2. Ukugcinwa rhoqo kunye nokutshintshwa kwamacandelo
Ukugcinwa rhoqo okupheleleyo kwecompressor yeyona nto ibalulekileyo ukuqinisekisa ukusebenza kwayo okuzinzileyo ixesha elide. Ngokubanzi, icompressor kufuneka ilungiswe ngokwezinga eliphakathi rhoqo emva kweminyaka emi-2-3 ukuze ihlole kwaye ilungise izinto ezibalulekileyo zokuguguleka, ukubola, kunye nezinye iingxaki; Yenza uhlengahlengiso olukhulu rhoqo emva kweminyaka emi-5-10 ukuze itshintshe izinto eziguguleke kakhulu ezifana nee-impellers, ii-pistons, imizimba yesilinda, njl. Ngokugcinwa ngexesha elifanelekileyo kunye nokutshintshwa kwezinto, ubomi benkonzo yecompressor bunokwandiswa ngeminyaka emi-3-5 nangaphezulu.
3. Ukubeka iliso kwindlela osebenza ngayo kunye nokuphatha iimpazamo
Ngokusebenzisa iinkqubo zokubeka esweni eziphambili ukujonga iiparameter zokusebenza kwe-compressor ngexesha langempela, ezinje ngoxinzelelo, ubushushu, izinga lokuhamba, ukungcangcazela, njl.njl., iingxaki ezinokubakho zinokufunyanwa ngexesha elifanelekileyo kwaye kuthathwe amanyathelo. Umzekelo, xa kufunyenwe ukungcangcazela okungaqhelekanga kwe-compressor, kusenokuba ngenxa yeengxaki ezinje ngokungalingani kwe-impeller okanye ukuguguleka kweebheringi. Ukugcinwa ngexesha elifanelekileyo kunokuthintela isiphene ukuba singakhuli ngakumbi, ngaloo ndlela kwandise ubomi benkonzo ye-compressor.
