Xa kwafika ixesha lokutshintsha indawo yokucoca umzi-mveliso we-spiral groove bearing assembly, iPhilips Medical Systems yajika yaya kwi-Ecoclean kwakhona.
Kungekudala emva kokufunyanwa kwee-X-ray nguWilhelm Conrad Röntgen ngo-1895, iPhilips Medical Systems DMC GmbH yaqala ukuphuhlisa nokwenza iityhubhu ze-X-ray kunye noCarl Heinrich Florenz Müller, umtshizi weglasi owazalelwa eThuringia, eJamani. NgoMatshi 1896, wayesele elakhe ityhubhu yokuqala ye-X-ray kwindawo yakhe yokusebenzela, kwaye emva kweminyaka emithathu wayifumana ilungelo elilodwa lomenzi wokuqala wemodeli yokulwa ne-cathode epholisiweyo ngamanzi. Isantya sophuhliso lweetyhubhu kunye nempumelelo yetekhnoloji yeetyhubhu ze-X-ray kwakhuthaza imfuno yehlabathi, kwaguqula ii-workshops zobugcisa zaba ziifektri ezikhethekileyo zeetyhubhu ze-X-ray. Ngo-1927, iPhilips, eyayingumnini-zabelo kuphela ngelo xesha, yathatha umzi-mveliso kwaye iqhubekile nokubumba itekhnoloji ye-X-ray ngezisombululo ezintsha kunye nophuculo oluqhubekayo.
Iimveliso ezisetyenziswa kwiinkqubo zempilo zePhilips kwaye zithengiswa phantsi kophawu lweDunlee zinegalelo elikhulu ekuphuculeni imifanekiso yokuxilonga, i-computed tomography (CT) kunye ne-interventional radiology.
“Ukongeza kwiindlela zanamhlanje zokwenza izinto, ukuchaneka okuphezulu kunye nokwenza ngcono inkqubo eqhubekayo, ucoceko lwamacandelo ludlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kokusebenza kunye nobude bexesha lemveliso yethu,” utshilo uAndré Hatje, uPhuhliso lweeNkqubo zeNjineli ePhakamileyo, iCandelo leeThubhu ze-X-ray. Iinkcukacha zongcoliseko lwamasuntswana aseleyo—amasuntswana amabini okanye angaphantsi kwe-5µm kunye nobukhulu obunye okanye obungaphantsi kwe-10µm—kufuneka zifezekiswe xa kucocwa iindawo ezahlukeneyo zetyhubhu ye-X-ray—kugxininiswa ucoceko olufunekayo kwinkqubo.
Xa kufika ixesha lokutshintsha izixhobo zokucoca zePhilips spiral groove bearing component, inkampani yenza ukuhlangabezana neemfuno zococeko oluphezulu njengeyona nto iphambili. I-molybdenum bearing yeyona nto iphambili kwityhubhu ye-X-ray yobuchwepheshe obuphezulu, emva kokusetyenziswa kwelaser kwesakhiwo se-groove, kwenziwa inyathelo lokusila elomileyo. Emva koko kulandela ukucoca, apho uthuli lokusila kunye nemikhondo yomsi kufuneka isuswe kwimigxobhozo eshiywe yinkqubo yelaser. Ukuze kube lula ukuqinisekiswa kwenkqubo, kusetyenziswa oomatshini abasemgangathweni abaqinileyo ukucoca. Ngokuchasene nale mvelaphi, umphuhlisi wenkqubo uqhagamshelane nabavelisi abaninzi bezixhobo zokucoca, kuquka i-Ecoclean GmbH eFilderstadt.
Emva kovavanyo lokucoca olwenziwe ngabavelisi abaliqela, abaphandi bafumanise ukuba ukucoceka okufunekayo kwezinto ezithwala imingxunya ye-helical kunokufezekiswa kuphela nge-EcoCwave ye-Ecoclean.
Lo matshini wenkqubo yokuntywilisela nokutshiza usebenza ngesixhobo sokucoca esifana nesasePhilips esasisetyenziswa ngaphambili kwaye sigubungela indawo yeemitha zesikwere eziyi-6.9. Sixhotyiswe ngeetanki ezintathu zokugcwala, enye yokuhlamba kunye nezimbini zokuhlamba, uyilo lwesilinda olulungelelanisiweyo lokuhamba kwamanzi kunye nendawo ethe nkqo zithintela ukwakheka kokungcola. Itanki nganye inesekethe eyahlukileyo yesixhobo sokucoca amanzi egcweleyo, ngoko ke ukucoca kunye nokucoca amanzi kuyahluzwa ngexesha lokuzaliswa nokukhutshelwa kwamanzi kunye nokungena ngaphakathi. Amanzi acociweyo ukuze kuhlanjululwe okokugqibela acutshungulwa kwinkqubo edibeneyo ye-Aquaclean.
Iimpompo ezilawulwa rhoqo zivumela ukuhamba kwamanzi ukuba kuhlengahlengiswe ngokweendawo ngexesha lokuzalisa nokukhupha amanzi. Oku kuvumela ukuba isitudiyo sizaliswe kumanqanaba ahlukeneyo ukuze kubekho utshintshiselwano oluxineneyo lweendaba kwiindawo eziphambili zendibano. Ezi ndawo zomiswa ngumoya oshushu kunye ne-vacuum.
“Savuya kakhulu ziziphumo zokucoca. Zonke iindawo ziphume efektri zicocekile kangangokuba sakwazi ukuzithumela ngqo kwigumbi elicocekileyo ukuze ziqhubeke nokucutshungulwa,” utshilo uHatje, ephawula ukuba amanyathelo alandelayo abandakanya ukuqhoboshela iindawo kunye nokuzigquma ngesinyithi esilulwelo.
IPhilips isebenzisa umatshini we-ultrasonic oneminyaka eli-18 ubudala onezigaba ezininzi ovela kwi-UCM AG ukucoca iindawo eziqala kwizikrufu ezincinci kunye neepleyiti ze-anode ukuya kwiisleeve ze-cathode ezinobubanzi obuyi-225mm kunye neepani ze-casing. Iintsimbi ezenziwe ngazo ezi ndawo zahlukahlukene ngokulinganayo - izinto ze-nickel-iron, intsimbi engatyiwayo, i-molybdenum, ithusi, i-tungsten kunye ne-titanium.
“Iinxalenye ziyacocwa emva kwamanyathelo ahlukeneyo okucubungula, njengokugaya kunye nokufaka i-electroplating, nangaphambi kokuqhoboshela okanye ukuqhoboshela. Ngenxa yoko, lo ngowona matshini usetyenziswa rhoqo kwinkqubo yethu yokubonelela ngezinto kwaye uyaqhubeka nokubonelela ngeziphumo zokucoca ezanelisayo,” uHatje Say.
Nangona kunjalo, inkampani ifikelele kumda wayo womthamo yaza yagqiba ekubeni ithenge umatshini wesibini kwi-UCM, icandelo le-SBS Ecoclean Group eligxile ekucoceni ngokuchanekileyo nangokucokisekileyo kakhulu. Nangona oomatshini abakhoyo babenokusingatha le nkqubo, inani lamanyathelo okucoca nokuhlamba, kunye nenkqubo yokomisa, iPhilips yayifuna inkqubo entsha yokucoca ekhawulezayo, eguquguqukayo nenika iziphumo ezingcono.
Ezinye izinto azizange zicocwe kakuhle ngenkqubo yazo yangoku ngexesha lesigaba sokucoca esiphakathi, nto leyo engazange ichaphazele iinkqubo ezilandelayo.
Kubandakanya ukulayisha nokukhupha izinto, inkqubo yokucoca nge-ultrasonic evalekileyo inezikhululo ezili-12 kunye neeyunithi ezimbini zokudlulisa izinto. Zingacwangciswa ngokukhululekileyo, njengoko kunjalo nangeeparameter zenkqubo kwiitanki ezahlukeneyo.
“Ukuze sihlangabezane neemfuno ezahlukeneyo zococeko lwezixhobo ezahlukeneyo kunye neenkqubo ezisezantsi, sisebenzisa iinkqubo zokucoca ezimalunga nama-30 ezahlukeneyo kwinkqubo, ezikhethwa ngokuzenzekelayo yinkqubo yebhakhowudi edibeneyo,” ucacisa uHatje.
Iirakhi zokuthutha zale nkqubo zixhotyiswe ngeegripper ezahlukeneyo ezithatha izikhongozeli zokucoca kwaye zenze imisebenzi efana nokuphakamisa, ukwehlisa kunye nokujikeleza kwisikhululo sokucubungula. Ngokwesicwangciso, isiphumo esinokwenzeka ziibhasikithi ezili-12 ukuya kwezili-15 ngeyure ezisebenza ngeeshifti ezintathu, iintsuku ezi-6 ngeveki.
Emva kokulayisha, iitanki zokuqala ezine zenzelwe inkqubo yokucoca ngenyathelo lokuhlamba eliphakathi. Ukuze ufumane iziphumo ezingcono nezikhawulezayo, itanki yokucoca ixhotyiswe ngamaza e-ultrasound amaninzi (25kHz kunye ne-75kHz) ezantsi nasemacaleni. I-flange ye-sensor yeplate ifakwe kwitanki yamanzi ngaphandle kwezinto zokuqokelela ukungcola. Ukongeza, itanki yokuhlamba inenkqubo yokucoca esezantsi kwaye idlula kumacala omabini ukuze kukhutshwe amasuntswana axhonyiweyo nadadayo. Oku kuqinisekisa ukuba naluphi na ukungcola okususiweyo okuqokelelene ezantsi kwahlulwe yi-flush nozzle kwaye kutsalwe kwindawo ephantsi yetanki. Ulwelo oluvela kumphezulu nakwiinkqubo zokucoca ezisezantsi lucutshungulwa ngeesekethe zokucoca ezahlukeneyo. Itanki yokucoca ikwaxhotyiswe ngesixhobo sokususa amafutha se-electrolytic.
“Siyile le nto nge-UCM yoomatshini abadala kuba ikwasivumela ukuba sicoce iindawo ngepeyinti yokupolisha eyomileyo,” utshilo uHatje.
Nangona kunjalo, ukucoca okutsha okutsha kubhetele kakhulu. Ukuhlamba ngamanzi acocekileyo kufakwe kwisitishi sesihlanu sonyango ukususa uthuli olucolekileyo olusanamathele kumphezulu emva kokucoca kunye nokuhlamba kokuqala.
Ukuhlamba ngokutshiza kulandelwa ziindawo ezintathu zokuhlamba ngokuntywilisela. Kwiindawo ezenziwe ngezinto zentsimbi, kongezwa i-corrosion inhibitor kumanzi asuswe i-ion asetyenziswe kumjikelo wokugqibela wokuhlamba. Zonke iindawo ezine zokuhlamba zinezixhobo zokuphakamisa ezizodwa zokususa iingobozi emva kwexesha elithile lokuhlala kunye nokuphazamisa iindawo ngelixa zihlamba. Izitishi ezimbini ezilandelayo zokomisa ngokungaphelelanga zixhotyiswe ngee-infrared vacuum dryers ezidibeneyo. Kwindawo yokukhupha impahla, indlu enebhokisi yokuhambahamba ye-laminar edibeneyo ithintela ukungcola kwezixhobo.
“Inkqubo entsha yokucoca isinika iindlela ezininzi zokucoca, nto leyo esivumela ukuba sifumane iziphumo ezingcono zokucoca ngexesha elifutshane lokujikeleza. Yiyo loo nto siceba ukuba i-UCM iphucule ngokufanelekileyo oomatshini bethu abadala,” uqukumbele watsho uHatje.
