Pamene nthawi inakwana yoti fakitale isinthe makina oyeretsera zitsulo zozungulira, Philips Medical Systems inayambanso kugwiritsa ntchito Ecoclean.
Patangopita nthawi yochepa kuchokera pamene Wilhelm Conrad Röntgen anapeza ma X-ray mu 1895, Philips Medical Systems DMC GmbH inayamba kupanga ndi kupanga machubu a X-ray pamodzi ndi Carl Heinrich Florenz Müller, katswiri wopaka magalasi wobadwira ku Thuringia, Germany. Pofika mu Marichi 1896, anali atapanga chubu choyamba cha X-ray mu workshop yake, ndipo patatha zaka zitatu adapanga patent yoyamba yoziziritsa ndi madzi yotsutsana ndi cathode. Kuthamanga kwa kupanga machubu ndi kupambana kwa ukadaulo wa machubu a X-ray kunapangitsa kuti pakhale kufunikira kwapadziko lonse lapansi, zomwe zinasintha ma workshop aluso kukhala mafakitale apadera a machubu a X-ray. Mu 1927, Philips, yemwe anali mwiniwake yekha panthawiyo, adatenga fakitaleyo ndipo akupitilizabe kupanga ukadaulo wa X-ray ndi mayankho atsopano komanso kusintha kosalekeza.
Zinthu zomwe zimagwiritsidwa ntchito mu machitidwe azaumoyo a Philips ndikugulitsidwa pansi pa dzina la Dunlee zathandiza kwambiri pakupita patsogolo kwa kujambula zithunzi, computed tomography (CT) ndi interventional radiology.
"Kuphatikiza pa njira zamakono zopangira zinthu, kulondola kwambiri komanso kukonza njira mosalekeza, ukhondo wa zigawo umagwira ntchito yofunika kwambiri pakutsimikizira kudalirika kwa ntchito zathu komanso kukhala ndi moyo wautali," akutero André Hatje, Senior Engineer Process Development, X-ray Tubes Division. Mafotokozedwe a kuipitsidwa kwa tinthu totsalira—tinthu tating'onoting'ono ta 5µm kapena tocheperapo ndi kukula kwa 10µm kamodzi kapena kocheperapo—ayenera kukwaniritsidwa poyeretsa zigawo zosiyanasiyana za chubu cha X-ray—pogogomezera ukhondo wofunikira panthawiyi.
Nthawi ikafika yoti musinthe zida zoyeretsera za Philips spiral groove bearing component, kampaniyo imakwaniritsa zofunikira zaukhondo wapamwamba ngati muyezo wake waukulu. Choyeretsera cha molybdenum ndiye maziko a chubu cha X-ray chaukadaulo wapamwamba, pambuyo pogwiritsa ntchito laser pa kapangidwe ka groove, sitepe youma imachitika. Kuyeretsa kumatsatira, pomwe fumbi ndi utsi ziyenera kuchotsedwa m'mipata yomwe yasiyidwa ndi laser. Kuti kutsimikizika kwa njira kukhale kosavuta, makina okhazikika amagwiritsidwa ntchito poyeretsa. Potengera izi, wopanga njira adalumikizana ndi opanga angapo a zida zoyeretsera, kuphatikiza Ecoclean GmbH ku Filderstadt.
Pambuyo poyesa kuyeretsa ndi opanga angapo, ofufuzawo adatsimikiza kuti ukhondo wofunikira wa zigawo zozungulira za helical groove ungathe kupezeka kokha ndi EcoCwave ya Ecoclean.
Makina awa oyeretsera madzi ndi kupopera madzi amagwira ntchito ndi njira yoyeretsera ya acidic yomwe imagwiritsidwa ntchito kale ku Philips ndipo imakwirira malo okwana 6.9 masikweya mita. Ali ndi matanki atatu odzaza madzi, limodzi lotsuka ndi awiri otsukira, kapangidwe kake ka cylindrical kokhazikika komanso malo oyima bwino amaletsa dothi kuti lisaunjikane. Thanki iliyonse ili ndi dera losiyana la media lomwe limasefedwa madzi onse, kotero kuyeretsa ndi kutsuka madzi kumasefedwa panthawi yodzaza ndi kutulutsa madzi komanso podutsa. Madzi oyeretsedwa kuti asambitsidwe komaliza amakonzedwa mu dongosolo lophatikizika la Aquaclean.
Mapampu olamulidwa ndi ma frequency amalola kuti madzi aziyenda molingana ndi zigawo panthawi yodzaza ndi kutulutsa madzi. Izi zimathandiza kuti chipinda chojambulira chizidzazidwa pamlingo wosiyanasiyana kuti chizitha kusinthana ndi zinthu zolemera m'malo ofunikira kwambiri. Kenako ziwalozo zimaumitsidwa ndi mpweya wotentha ndi vacuum.
"Tinasangalala kwambiri ndi zotsatira za kuyeretsa. Ziwalo zonse zinatuluka mufakitale zoyera kwambiri kotero kuti tinatha kuzisamutsa mwachindunji kuchipinda choyera kuti zikonzedwenso," adatero Hatje, ponena kuti njira yotsatira inali kuphimba ziwalozo ndi kuzipaka ndi Chitsulo chamadzimadzi.
Philips imagwiritsa ntchito makina a ultrasonic azaka 18 okhala ndi magawo ambiri ochokera ku UCM AG kuti ayeretse ziwalo kuyambira zomangira zazing'ono ndi mbale za anode mpaka manja a cathode a 225mm m'mimba mwake ndi mapani ophimba. Zitsulo zomwe zigawozi zimapangidwa nazo ndizosiyanasiyana - zinthu za nickel-iron, chitsulo chosapanga dzimbiri, molybdenum, mkuwa, tungsten ndi titaniyamu.
"Zigawo zimatsukidwa pambuyo pokonza zinthu zosiyanasiyana, monga kupukuta ndi kuyika ma electroplating, komanso musanazike kapena kuziyika pa brazing. Chifukwa chake, iyi ndi makina omwe amagwiritsidwa ntchito kwambiri mu dongosolo lathu loperekera zinthu ndipo ikupitilizabe kupereka zotsatira zokhutiritsa zoyeretsa," Hatje Say.
Komabe, kampaniyo inafika polekezera mphamvu zake ndipo inaganiza zogula makina ena kuchokera ku UCM, gawo la SBS Ecoclean Group lomwe limadziwika bwino ndi kuyeretsa kolondola komanso kosalala kwambiri. Ngakhale makina omwe alipo kale anali ndi mphamvu zochitira izi, kuchuluka kwa njira zotsukira ndi kutsuka, komanso njira yowumitsa, Philips inkafuna njira yatsopano yotsukira yomwe inali yachangu, yosinthasintha komanso yopereka zotsatira zabwino.
Zigawo zina sizinatsukidwe bwino ndi makina awo apano panthawi yoyeretsa yapakati, zomwe sizinakhudze njira zomwe zatsatiridwa.
Kuphatikizapo kukweza ndi kutsitsa, makina oyeretsera a ultrasound omwe ali mkati mwake ali ndi malo 12 ndi mayunitsi awiri osamutsira. Amatha kukonzedwa mosavuta, komanso magawo a njira m'matanki osiyanasiyana.
"Kuti tikwaniritse zofunikira zosiyanasiyana za ukhondo wa zigawo zosiyanasiyana ndi njira zotsatizana, timagwiritsa ntchito mapulogalamu pafupifupi 30 osiyanasiyana oyeretsera mu dongosololi, omwe amasankhidwa okha ndi dongosolo lolumikizidwa la barcode," akufotokoza Hatje.
Ma raki onyamulira katundu a dongosololi ali ndi zogwirira zosiyanasiyana zomwe zimanyamula zotsukira ndikuchita ntchito monga kunyamula, kutsitsa ndi kuzungulira pamalo opangira zinthu. Malinga ndi dongosololi, njira yotheka yogwiritsira ntchito ndi mabasiketi 12 mpaka 15 pa ola limodzi, zomwe zimagwira ntchito katatu, masiku 6 pa sabata.
Pambuyo podzaza, matanki anayi oyamba amapangidwira njira yoyeretsera yokhala ndi sitepe yotsuka yapakatikati. Kuti mupeze zotsatira zabwino komanso zachangu, thanki yoyeretsera imakhala ndi mafunde a ultrasound ambiri (25kHz ndi 75kHz) pansi ndi m'mbali. Flange ya sensa ya mbale imayikidwa mu thanki yamadzi yopanda zinthu zosonkhanitsira dothi. Kuphatikiza apo, thanki yotsukira ili ndi njira yosefera pansi ndipo imadzaza mbali zonse ziwiri kuti tinthu tomwe timayimitsidwa komanso toyandama titulutsidwe. Izi zimatsimikizira kuti zonyansa zilizonse zomwe zachotsedwa zomwe zimasonkhana pansi zimalekanitsidwa ndi nozzle yothira ndikuyamwa pamalo otsika kwambiri a thanki. Madzi ochokera pamwamba ndi pansi pa makina osefera amakonzedwa kudzera m'mabwalo osiyana osefera. Thanki yoyeretsera ilinso ndi chipangizo chochotsera mafuta cha electrolytic.
"Tapanga izi ndi UCM za makina akale chifukwa zimatithandizanso kuyeretsa ziwalo ndi phala louma lopukuta," adatero Hatje.
Komabe, kuyeretsa kumene kwangowonjezeredwako kuli bwino kwambiri. Kutsuka ndi madzi oyeretsedwa kumayikidwa mu siteshoni yachisanu yochotsera fumbi losalala lomwe limamatira pamwamba pake mutatsuka ndikutsuka koyamba.
Kutsuka kwa spray kumatsatiridwa ndi malo atatu otsukira madzi. Pazigawo zopangidwa ndi zitsulo, choletsa dzimbiri chimawonjezedwa ku madzi oyeretsedwa omwe amagwiritsidwa ntchito mu nthawi yomaliza yotsuka. Malo onse anayi otsukira ali ndi zida zonyamulira zochotsera madengu pambuyo pa nthawi yokhazikika ndikusuntha ziwalozo pamene akutsuka. Malo awiri otsatira owumitsa pang'ono ali ndi zowumitsira zosakaniza za infrared vacuum. Pa malo otulutsira madzi, nyumba yokhala ndi bokosi loyendera la laminar yolumikizidwa imaletsa kubwezeretsanso kwa zigawozo.
"Dongosolo latsopano loyeretsera limatipatsa njira zambiri zoyeretsera, zomwe zimatilola kupeza zotsatira zabwino zoyeretsera ndi nthawi yochepa yozungulira. Ndicho chifukwa chake tikukonzekera kuti UCM ikonze bwino makina athu akale," anatero Hatje.
