Kodi moyo wautumiki wa kompresa mu hydrogen refueling station ndi utali wotani?

Moyo wautumiki wa ma hydrogen refueling station compressor umakhudzidwa ndi zinthu zosiyanasiyana. Nthawi zambiri, moyo wawo wautumiki umakhala wazaka 10-20, koma zenizeni zimatha kusiyana chifukwa cha izi:

Mmodzi, Compressor mtundu ndi kapangidwe

1. kompresa wobwerezabwereza

Mtundu uwu wa kompresa umakanikiza mpweya wa haidrojeni kudzera mukuyenda mobwereza kwa pisitoni mkati mwa silinda. Kapangidwe kake kamapangitsa kuti ikhale yovuta kwambiri komanso imakhala ndi magawo ambiri osuntha. Mwachizoloŵezi, ngati kusamalidwa bwino, moyo wautumiki wa ma compressor obwereza ukhoza kukhala zaka 10-15. Ma compressor amakono obwerezabwereza pogwiritsa ntchito zida zapamwamba komanso mapangidwe okhathamiritsa atha kukulitsidwa mpaka zaka 15.

2. Centrifugal kompresa

Centrifugal kompresa imathandizira ndi compress wa haidrojeni mpweya kudzera mkulu-liwiro atembenuza impellers.Kapangidwe kake ndi yosavuta, ndi mbali zochepa kusuntha, ndipo imagwira ntchito ndi stably pansi pa zikhalidwe zoyenera ntchito.During ntchito yachibadwa, moyo utumiki wa kompresa centrifugal angafikire 15-20 years.Isspecially kwa mkulu-mapeto ozungulira impellers ntchito yokonza hydrogen centrifugal ntchito yawo yabwino, centrifugal utumiki refuling ntchito yabwino. moyo ukhoza kukhala wautali.

Awiri, Mikhalidwe yogwirira ntchito ndi magawo ogwiritsira ntchito

1. Kupanikizika ndi kutentha

Kuthamanga kogwira ntchito ndi kutentha kwa ma hydrogen refueling station compressor zimakhudza kwambiri moyo wawo wautumiki.Kupanikizika kogwira ntchito kwa kompresa wamba wa hydrogen refueling station kuli pakati pa 35-90MPa.Ngati kompresa ikugwira ntchito pafupi ndi malire apamwamba kwa nthawi yayitali, idzawonjezera mavalidwe ndi kutopa, potero kufupikitsa moyo wake wautumiki. kufupikitsidwa ndi zaka 2-3 poyerekeza ndi kugwira ntchito mozungulira 60MPa.

Pankhani ya kutentha, compressor imapanga kutentha panthawi yogwira ntchito, ndipo kutentha kwambiri kungakhudze magwiridwe antchito ndi mphamvu ya zipangizo. Nthawi zambiri, kutentha kwa ntchito ya kompresa kuyenera kuyendetsedwa mosiyanasiyana, monga osapitilira 80-100 ℃. Ngati kutentha kumadutsa nthawi yayitali, kungayambitse mavuto monga kukalamba kwa zisindikizo ndi kuchepa kwa ntchito ya mafuta odzola, zomwe zingachepetse moyo wautumiki wa compressor.

2. Kuyenda ndi kuchuluka kwa katundu

Kuthamanga kwa haidrojeni kumatsimikizira mkhalidwe wa katundu wa kompresa. Ngati kompresa ikugwira ntchito pamlingo wothamanga kwambiri komanso kuchuluka kwa katundu wambiri (monga kupitilira 80% ya kuchuluka kwa kapangidwe kake) kwa nthawi yayitali, zida zazikulu monga mota, impeller (za centrifugal compressor), kapena pisitoni (zobwerezabwereza) mkati mwake zidzavala zotsutsana ndi kukakamiza kwakukulu, ndi otsika kwambiri, kompresa akhoza kukhala ndi ntchito yosakhazikika ndipo imakhala ndi zotsatirapo zoipa pa moyo wake wautumiki.Kulankhula kawirikawiri, ndi koyenera kwambiri kulamulira kuchuluka kwa katundu wa compressor pakati pa 60% ndi 80%, zomwe zingathe kutalikitsa moyo wake wautumiki ndikuonetsetsa kuti zikuyenda bwino.

Chachitatu, Kusamalira ndi kusamalira udindo

1. Kusamalira tsiku ndi tsiku

Kuwunika pafupipafupi, kuyeretsa, kuthira mafuta, ndi ntchito zina zanthawi zonse zokonza ma compressor ndizofunikira kuti atalikitse moyo wawo wantchito.
Mwachitsanzo, kusinthanitsa mafuta opaka nthawi zonse ndi zisindikizo kumatha kupewa kutayika kwa zigawo ndi kutayikira. Nthawi zambiri amalimbikitsidwa kuti asinthe mafuta opaka maola 3000-5000 aliwonse, ndikusintha zisindikizo zaka 1-2 zilizonse malinga ndi momwe amavalira.

Kuyeretsa kolowera ndi kutuluka kwa kompresa kuti zonyansa zisalowe mkati ndi gawo lofunikira pakukonza tsiku ndi tsiku.
Ngati fyuluta yolowera mpweya sinatsukidwe munthawi yake, fumbi ndi zonyansa zimatha kulowa mu kompresa, zomwe zimapangitsa kuti chigawocho chiwonjezeke ndipo mwina kufupikitsa moyo wautumiki wa kompresa ndi zaka 1-2.

2. Kusamalira nthawi zonse ndi kusintha chigawo

Kukonzekera kosalekeza kwa kompresa ndiye chinsinsi chowonetsetsa kuti ntchito yake ikhale yokhazikika kwa nthawi yayitali. Nthawi zambiri, kompresa iyenera kukonzedwanso zaka 2-3 zilizonse kuti ayang'ane ndikukonza zida zazikulu zomwe zavala, dzimbiri, ndi zina. m'malo, moyo wautumiki wa kompresa ukhoza kukulitsidwa ndi zaka 3-5 kapena kupitilira apo.

3. Kuyang'anira ntchito ndi kukonza zolakwika

Pogwiritsa ntchito njira zowunikira zapamwamba kuti ziwonetsere momwe ma compressor amagwirira ntchito munthawi yeniyeni, monga kuthamanga, kutentha, kuthamanga, kugwedezeka, ndi zina zotero, mavuto omwe angakhalepo amatha kuzindikirika panthawi yake ndipo akhoza kuchitidwa. Kusamalira nthawi yake kumatha kuletsa cholakwikacho kuti chisakule, potero kukulitsa moyo wautumiki wa kompresa.
