Moyo wa ntchito wa ma compressor a hydrogen refilling station umakhudzidwa ndi zinthu zosiyanasiyana. Nthawi zambiri, moyo wawo wa ntchito ndi pafupifupi zaka 10-20, koma mkhalidwe wake ungasiyane chifukwa cha zinthu zotsatirazi:
Chimodzi, mtundu wa kompresa ndi kapangidwe
1. Kompresa wobwerezabwereza
Mtundu uwu wa compressor umakanikiza mpweya wa haidrojeni kudzera mu kayendedwe ka pisitoni mkati mwa silinda. Kapangidwe kake kamapangitsa kuti ikhale yovuta kupanga ndipo imakhala ndi zinthu zambiri zosuntha. Kawirikawiri, ngati itasamalidwa bwino, moyo wa ntchito wa compressors wobwerezabwereza ukhoza kukhala pafupifupi zaka 10-15. Mwachitsanzo, ma compressors ena oyambilira obwerezabwereza omwe adapangidwa kale akhoza kukhala ndi moyo wa ntchito pafupifupi zaka 10 chifukwa cha zofooka zaukadaulo ndi zinthu zina; Moyo wa ntchito wa compressors zamakono zobwerezabwereza zomwe zimagwiritsa ntchito zipangizo zapamwamba komanso mapangidwe abwino kwambiri zitha kukulitsidwa mpaka zaka pafupifupi 15.
2. Chokometsa cha centrifugal
Ma compressor a centrifugal amafulumizitsa ndikupondereza mpweya wa hydrogen kudzera mu ma impeller ozungulira mwachangu. Kapangidwe kake ndi kosavuta, ndi zigawo zochepa zosuntha, ndipo amagwira ntchito mokhazikika pansi pa mikhalidwe yoyenera yogwirira ntchito. Pakagwiritsidwa ntchito bwino, nthawi yogwira ntchito ya ma compressor a centrifugal imatha kufika zaka 15-20. Makamaka ma compressor apamwamba a centrifugal omwe amagwiritsidwa ntchito m'malo ena akuluakulu odzaza mafuta a hydrogen, akakonzedwa bwino, nthawi yawo yogwira ntchito imatha kukhala yayitali.
Awiri, zinthu zogwirira ntchito ndi magawo ogwirira ntchito
1. Kupanikizika ndi kutentha
Kuthamanga kwa ntchito ndi kutentha kwa ma compressor a hydrogen refueling station zimakhudza kwambiri moyo wawo wa ntchito. Kuthamanga kwa ntchito kwa compressor wamba wa hydrogen refueling station kuli pakati pa 35-90MPa. Ngati compressor ikugwira ntchito pafupi ndi malire a kuthamanga kwamphamvu kwa nthawi yayitali, idzawonjezera kuwonongeka kwa zigawo ndi kutopa, motero imachepetsa moyo wake wa ntchito. Mwachitsanzo, pamene kuthamanga kwa ntchito kukupitirirabe pafupifupi 90MPa, moyo wa ntchito wa compressor ukhoza kuchepetsedwa ndi zaka 2-3 poyerekeza ndi kugwira ntchito pafupifupi 60MPa.
Ponena za kutentha, compressor imapanga kutentha ikagwira ntchito, ndipo kutentha kwambiri kungakhudze magwiridwe antchito a zigawo ndi mphamvu ya zipangizo. Muzochitika zachizolowezi, kutentha kwa compressor kuyenera kulamulidwa mkati mwa mtunda winawake, monga kusapitirira 80-100 ℃. Ngati kutentha kupitirira mtunda uwu kwa nthawi yayitali, kungayambitse mavuto monga kukalamba kwa zisindikizo ndi kuchepa kwa magwiridwe antchito a mafuta opaka, zomwe zimachepetsa nthawi yogwira ntchito ya compressor.
2. Kuyenda ndi kuchuluka kwa katundu
Kuthamanga kwa haidrojeni kumatsimikiza momwe compressor imagwirira ntchito. Ngati compressor ikugwira ntchito pamlingo wokwera wa kuyenda kwa magetsi komanso kuchuluka kwa katundu (monga kupitirira 80% ya kuchuluka kwa katundu wopangidwa) kwa nthawi yayitali, zigawo zazikulu monga mota, impeller (ya ma compressor a centrifugal), kapena piston (ya ma compressor obwerezabwereza) mkati mwake zidzakumana ndi kupsinjika kwakukulu, zomwe zimapangitsa kuti zigawozo ziwonongeke komanso kukalamba mofulumira. M'malo mwake, ngati kuchuluka kwa katundu kuli kochepa kwambiri, compressor ikhoza kugwira ntchito mosakhazikika ndipo ingakhudze moyo wake wa ntchito. Nthawi zambiri, ndikofunikira kwambiri kuwongolera kuchuluka kwa katundu wa compressor pakati pa 60% ndi 80%, zomwe zitha kutalikitsa moyo wake wa ntchito pomwe zikuwonetsetsa kuti ikugwira ntchito bwino.
Zitatu, Kukonza ndi kusamalira
1. Kukonza tsiku ndi tsiku
Kuyang'anira pafupipafupi, kuyeretsa, kudzola mafuta, ndi ntchito zina zosamalira ma compressor ndikofunikira kwambiri kuti azitha kugwira ntchito nthawi yayitali.
Mwachitsanzo, kusintha mafuta odzola ndi zomatira nthawi zonse kungalepheretse kuwonongeka ndi kutuluka kwa zinthu zina. Nthawi zambiri amalangizidwa kuti asinthe mafuta odzola maola 3000-5000 aliwonse, ndikusinthira zomatira zaka 1-2 zilizonse malinga ndi momwe zimagwirira ntchito.
Kuyeretsa malo olowera ndi otulukira a compressor kuti zinyalala zisalowe mkati ndi gawo lofunikira pakukonza tsiku ndi tsiku.
Ngati fyuluta yolowera mpweya siitsukidwa nthawi yake, fumbi ndi zinyalala zimatha kulowa mu compressor, zomwe zimapangitsa kuti zinthu ziwonongeke komanso mwina kufupikitsa moyo wa compressor ndi zaka 1-2.
2. Kusamalira nthawi zonse ndi kusintha zigawo zina
Kusamalira compressor nthawi zonse ndi chinsinsi choonetsetsa kuti ikugwira ntchito bwino kwa nthawi yayitali. Nthawi zambiri, compressor iyenera kukonzedwa pang'onopang'ono zaka 2-3 zilizonse kuti iwunike ndikukonza zigawo zofunika kuti ione ngati zawonongeka, dzimbiri, ndi zina; Chitani kukonzanso kwakukulu zaka 5-10 zilizonse kuti musinthe zigawo zomwe zawonongeka kwambiri monga ma impeller, ma pistoni, matupi a masilinda, ndi zina zotero. Mwa kukonza nthawi yake komanso kusintha zigawo, moyo wa compressor ukhoza kukulitsidwa ndi zaka 3-5 kapena kuposerapo.
3. Kuyang'anira ntchito ndi kusamalira zolakwika
Mwa kugwiritsa ntchito njira zowunikira zapamwamba kuti ziwunikire magawo ogwirira ntchito a compressor nthawi yeniyeni, monga kuthamanga, kutentha, kuthamanga kwa madzi, kugwedezeka, ndi zina zotero, mavuto omwe angakhalepo amatha kuzindikirika munthawi yake ndipo njira zitha kuchitidwa. Mwachitsanzo, pamene kugwedezeka kosazolowereka kwa compressor kwapezeka, kungakhale chifukwa cha mavuto monga kusalingana kwa impeller kapena kuwonongeka kwa mabearing. Kukonza nthawi yake kungalepheretse vutolo kukula, motero kukulitsa moyo wa compressor.
