Embonini yokuvala, ama-polyurethane (PU) O-rings asetshenziswa kabanzi emishinini ye-hydraulic, emishinini ezenzakalelayo, emishinini yamandla emisha nakwezinye izinkambu ezibalulekile, ngenxa yokumelana kwawo okuvelele kokuklebhula, ukumelana kokuguguleka okuphezulu kanye nokuguquguquka okuphezulu. Inkinga yemboni ende isalokhu ikhona: noma ngabe abakhiqizi basebenzisa izinto ezifanayo ze-polyurethane eluhlaza ukuze bakhiqize ama-O-rings, imikhiqizo eqediwe isabonisa ukungafani okukhulu emandleni okuvala, ukumelana nesimo sezulu kanye nokuphila kwesevisi. Ucwaningo lobuchwepheshe bezimboni luqinisekisile ukuthi ukwakheka kwefomula akuseyona into kuphela ehlukanisa ikhwalithi yomkhiqizo. I-flash eseleyo evela enkambisweni yokubumba iyiphutha elifihliwe kalula. I-STMC (Nanjing) Precision Machinery yethule imishini yokuvala i-cryogenic enembile kakhulu futhi esebenza kahle kakhulu, ebhekana ngokuphelele namaphuzu obuhlungu bokuvala ama-sealing rings avela emthonjeni futhi ithinta ngokugcwele amandla okusebenza kwezinto ze-polyurethane.
Ama-PU O-rings akhiqizwa kakhulu ngokusebenzisa ukubumbana kokucindezela kanye ne-vulcanization. I-flash encane kanye nama-burrs akheka ngokungenakugwenywa engxenyeni engaphandle ngenxa yemigqa yokuhlukana kwesikhunta kanye nokuchichima kwezinto. Iningi labakhiqizi abancane nabaphakathi nendawo bagxila kakhulu ekwenzeni ngcono ifomula, kodwa basathembele ezindleleni zokucubungula ezingavuthiwe njengokusika ngesandla ngesikere kanye nokupholisha okulula kwesondo lokugaya ukuze kukhishwe umoya. Lezi zindlela azikwazi ukususa ama-burrs amancane, futhi zivame ukuklwebha ama-O-rings futhi zibangele ukuphambuka kobukhulu. I-flash ebonakala iyinto encane izophazamisa ukuqina kokulingana phakathi kwama-O-rings kanye nemifantu, okuholela ekuphuzeni nasekunciphiseni ingcindezi ngaphansi kwezimo zokusebenza ezicindezelayo. Njengamaphuzu abuthakathaka ngokwesakhiwo ngaphansi kokucindezeleka, ama-burrs athambekele ekuqhekekeni nasekudabukeni kuqala ngesikhathi sokunyakaza okuphindaphindayo kwemishini, okuphazamisa kakhulu ukumelana nokudabuka okungokwemvelo kwe-polyurethane. Ngaphezu kwalokho, ama-burrs anokumelana nokuguga okuphansi kakhulu kunomzimba oyinhloko womkhiqizo. Awohloka ngokushesha ezindaweni zokushisa eziphakeme/eziphansi kanye nezindawo ezilimazayo, okwenza yonke indandatho yokuvala ihluleke ngaphambi kwesikhathi. Imfucumfucu ewile izophinde iguge izifunda zikawoyela kanye nezingxenye zokunemba zemishini.
Ukuhlanza okucacile kwe-cryogenic kuvelele njengesixazululo esifanele sokususa amaphutha e-flash nokukhulisa ukusebenza kwezinto ezibonakalayo. Njengebhizinisi likazwelonke lobuchwepheshe obuphezulu kanye nebhizinisi lesifundazwe saseJiangsu elithi "Specialized, Refined, Differential and Innovative" elinolwazi olungaphezu kweminyaka eyishumi kubuchwepheshe bokuhlanza okuphansi kwezinga lokushisa, i-STMC isebenzisa amakhono e-Sino-Japanese joint R&D kanye nobuchwepheshe obuningi obunelungelo lobunikazi ukuze inikeze izixazululo eziphelele ze-cryogenic deflashing ezenziwe ngokwezifiso ezinikezelwe kuma-PU sealing rings.
Ifakwe uhlelo lokulawula izinga lokushisa olunembile kakhulu olugcina ukuphambuka okuncane kokushisa, imishini ihlanganisa ngokunembile ama-edge burrs kuphela emazingeni okushisa aphansi ngenkathi igcina ngokugcwele ukuqina kanye nezakhiwo zomzimba we-PU O-ring. Inesakhiwo sokuqhumisa imidiya esinejubane eliphezulu se-impeller esikabili, isusa i-flash ngokuphelele kuzo zonke izingqimba ngaphandle kokulimaza ubukhulu bomkhiqizo, ukuphela kwendawo noma isakhiwo sama-molecule sezinto. Imikhiqizo eqediwe inemiphetho ebushelelezi necocekile kanye nokuvumelana okuhle kakhulu kobukhulu ekukhiqizweni kwesisindo, ihlangabezana nezindinganiso zokususa ukungcola ngokunemba okuphezulu kakhulu.
Ngokuphathelene nokusebenza kahle kokukhiqiza, imishini yokuhlanza e-cryogenic ye-STMC ezenzakalelayo yandisa umkhiqizo uma kuqhathaniswa nokusebenza ngesandla. Ivumela ukucutshungulwa okukhulu kwama-PU O-rings, inciphisa ngempumelelo izindleko zabasebenzi futhi inciphise amazinga anephutha ngenkathi ilinganisa ikhwalithi ephezulu kanye nokusebenza kahle kokukhiqiza ngobuningi. Ama-PU O-rings acutshungulwa yile mishini abona ukuthuthuka okuphelele ekusebenzeni kokuvala, ukumelana nokushisa okuphezulu nokuphansi, kanye nokuqina kokuguga. Ngezinto zokusetshenziswa ezifanayo, ukusebenza kwawo jikelele kudlula kakhulu imikhiqizo ecutshungulwa ngezindlela ezivamile zokuhlanza.
Abakhiqizi bezimbobo zezimoto kanye nezingxenye ze-hydraulic babike ekuhlolweni kwensimu ukuthi ngemva kokusebenzisa izixazululo ze-STMC zokususa ukungcola ezisebenzisa i-cryogenic, isikhathi senkonzo yezindandatho zokuvala siyandiswa, futhi amazinga okuvuza kwemishini ehla kakhulu. Imikhiqizo yabo ithole ukuncintisana okunamandla ezimakethe zokubhida kanye nezisekelayo eziphezulu.
Namuhla, ukuncintisana okuhlanganisiwe kwezinto zokusetshenziswa kuye kwanda embonini yokubopha, futhi ukuthembela kuphela ekuthuthukisweni kwefomula akusakwazi ukuqhubeka nentuthuko. Isekelwa imishini yokuhlanza i-cryogenic eqondile kakhulu futhi esebenza kahle kakhulu, i-STMC isiza abakhiqizi ukuthi basuse amaphutha e-flash afihliwe emthonjeni futhi banikeze ukusebenza okugcwele kwezinto ze-PU O-ring. Amasu okukhiqiza aqinile futhi acwengekile asekela imikhiqizo yokubopha esebenza kahle kakhulu. Benikwe amandla yimishini yobungcweti, abakhiqizi bokubopha bangagqashula emncintiswaneni wentengo ephansi, bathuthukise imikhiqizo yokubopha ezinzile nesezingeni eliphezulu, futhi baqhube yonke imboni yokubopha irabha nepulasitiki iye ekuqondeni okuphezulu, impilo yesevisi ende kanye nokwenza okuzenzakalelayo okugcwele.
