Kwishishini lokutywina, ii-polyurethane (PU) O-rings zisetyenziswa kakhulu kwizixhobo ze-hydraulic, oomatshini abazisebenzelayo, izixhobo zamandla amatsha kunye nezinye iindawo ezibalulekileyo, ngenxa yokumelana kwazo okubalaseleyo kokukrazula, ukumelana nokuguguleka okuphezulu kunye nokuguquguquka okuphezulu. Ingxaki yexesha elide kushishino isahleli: nokuba abavelisi basebenzisa izinto ezifanayo ze-polyurethane ukuvelisa ii-O-rings, iimveliso ezigqityiweyo zisabonisa ukungafani okukhulu kumandla okutywina, ukumelana nemozulu kunye nobomi benkonzo. Uphando lobuchwephesha bezoshishino luqinisekisile ukuba ukwakheka kwefomyula akuseyona nto yodwa eyahlula umgangatho wemveliso. I-flash eseleyo kwinkqubo yokubumba sisiphene esifihlakeleyo esingenakujongwa lula. I-STMC (Nanjing) Precision Machinery iqalise izixhobo zokunyibilikisa ezichanekileyo nezisebenza kakuhle, ezijongana ngokupheleleyo neendawo zokunyibilikisa iintlungu zeeringi zokutywina ezivela kumthombo kwaye zifikelela ngokupheleleyo kumandla okusebenza kwezixhobo ze-polyurethane.
Ii-PU O-rings zenziwa kakhulu ngokusebenzisa ukubumba okucinezelweyo kunye ne-vulcanization. I-Fine flash kunye nee-burrs ngokungenakuphepheka zenzeka kumjikelezo ongaphandle ngenxa yemigca yokuhlukana kwe-mold kunye nokugcwala kwezinto. Uninzi lwabavelisi abancinci nabaphakathi bagxila kakhulu ekuphuculeni ifomula, kodwa basaxhomekeke kwiindlela zokucubungula emva kokwenziwa okuluhlaza ezifana nokusika ngesandla ngesikere kunye nokupolisha okulula kwevili lokugaya ukuze kukhutshwe i-deflashing. Ezi ndlela azikwazi ukususa ii-burrs ezincinci, kwaye zidla ngokukrwela ii-O-rings kwaye zibangele ukuphambuka kobukhulu. I-flash ebonakala incinci iya kuphazamisa ukuqina kokulingana phakathi kwee-O-rings kunye nee-grooves, okukhokelela ekuvuzeni nasekunciphiseni uxinzelelo phantsi kweemeko zokusebenza ezinoxinzelelo oluphezulu. Njengamachaphaza abuthathaka ngokwesakhiwo phantsi koxinzelelo, ii-burrs zidla ngokuqhekeka nokukrazuka kuqala ngexesha lokuhamba kwezixhobo, okuphazamisa kakhulu ukumelana nokukrazuka okungokwemvelo kwe-polyurethane. Ukongeza, ii-burrs zinokumelana nokuguga okuphantsi kakhulu kunomzimba oyintloko wemveliso. Ziwohloka ngokukhawuleza kwiindawo ezishushu eziphezulu/eziphantsi kunye neendawo ezibolayo, nto leyo ebangela ukuba yonke i-sealing ring ingasebenzi ngaphambi kwexesha. Inkunkuma ewileyo iya kukwaphula iisekethe zeoyile kunye nezinto ezichanekileyo zoomatshini.
Ukucoca nge-cryogenic okuchanekileyo kugqame njengesisombululo esifanelekileyo sokususa iziphene ze-flash kunye nokwandisa ukusebenza kwezinto. Njengeshishini lesizwe elinobuchwepheshe obuphezulu kunye nelishishini lePhondo laseJiangsu "elikhethekileyo, eliHlaziyiweyo, eliHlengahlengisiweyo neliNtsha" elinamava angaphezu kweshumi leminyaka kubuchwepheshe bokucoca nge-deburring obuphantsi kobushushu, i-STMC isebenzisa ubuchule be-Sino-Japanese joint R&D kunye neetekhnoloji ezininzi ezinelungelo elilodwa lomenzi ukubonelela ngezisombululo ezipheleleyo zokucoca nge-cryogenic ezinikezelwe kwiindandatho zokuvala ze-PU.
Ixhotyiswe ngenkqubo yokulawula ubushushu echanekileyo kakhulu egcina ukuphambuka okuncinci kobushushu, izixhobo zigquma kuphela ii-edge burrs kumaqondo obushushu aphantsi ngelixa zigcina ngokupheleleyo ukuthamba kunye neempawu zomzimba we-PU O-ring. Inesakhiwo se-media blasting esine-impeller ezimbini, isusa i-flash ngokupheleleyo kuzo zonke ii-engile ngaphandle kokonakalisa ubungakanani bemveliso, ukugqitywa komphezulu okanye ulwakhiwo lwe-molecular lwento. Iimveliso ezigqityiweyo zinomgca ogudileyo nococekileyo kunye nokuhambelana okuhle kakhulu kwimveliso yobuninzi, zihlangabezana nemigangatho yokucoca ngokuchanekileyo okuphezulu kakhulu.
Ngokuphathelele ukusebenza kakuhle kwemveliso, izixhobo ze-STMC ezizenzekelayo zokukhupha ii-cryogenic deflashing zandisa imveliso xa kuthelekiswa nokusebenza ngesandla. Zivumela ukucutshungulwa okukhulu kwee-PU O-rings, zinciphisa ngempumelelo iindleko zomsebenzi kwaye zinciphise amazinga angalunganga ngelixa zilinganisa umgangatho ophezulu kunye nokusebenza kakuhle kwemveliso ngobuninzi. Ii-PU O-rings ezicutshungulwa zezi zixhobo zibona uphuculo olupheleleyo ekusebenzeni kokutywina, ukumelana nobushushu obuphezulu nobuphantsi, kunye nokuqina kokwaluphala. Ngezixhobo ezifanayo, ukusebenza kwazo ngokubanzi kudlula kakhulu iimveliso ezicutshungulwa ngeendlela zesiqhelo zokukhupha ii-deflashing.
Abavelisi bezitywino zeemoto kunye nezixhobo ze-hydraulic baxele kwiimvavanyo zasentsimini ukuba emva kokusebenzisa izisombululo ze-STMC ze-cryogenic deflashing, ubomi benkonzo yezindandatho zokuvala buyandiswa, kwaye amazinga okungaphumeleli kokuvuza kwezixhobo ehla kakhulu. Iimveliso zabo zifumene ukhuphiswano olunamandla kwiimarike ezithengisa amaxabiso kunye neemarike ezixhasayo eziphezulu.
Kule mihla, ukhuphiswano oluhambelanayo lwezinto eziluhlaza luye lwanda kwishishini lokutywina, kwaye ukuthembela kuphela ekuphuculeni ifomula akusakwazi ukuqhubeka nophuhliso. Ixhaswa zizixhobo zokunyibilikisa i-cryogenic ezisemgangathweni ophezulu nezisebenza kakuhle, i-STMC inceda abavelisi ukuba basuse iziphene ze-flash ezifihlakeleyo kumthombo kwaye banike ukusebenza ngokupheleleyo kwezixhobo ze-PU O-ring. Iindlela zokuvelisa eziqinileyo nezicociweyo zixhasa iimveliso zokutywina ezisebenza kakuhle. Bexhaswa zizixhobo zobungcali, abavelisi bokutywina banokuphuma kukhuphiswano oluphantsi olunexabiso eliphantsi, baphuhlise iimveliso zokutywina ezizinzileyo nezikumgangatho ophezulu, kwaye baqhube lonke ishishini lokutywina irabha kunye neplastiki ukuya ekuchanekeni okuphezulu, ubomi benkonzo ende kunye nokuzisebenzela ngokupheleleyo.
