I. Isikhokelo seMigangatho yeHlabathi esiPhambili seeNgxowa eziRhoxayo zoCoceko
Iimfuneko zococeko zemixokelelwane yeroller kwimishini yokucubungula ukutya azihlukaniswanga kodwa zifakwe kwinkqubo yokhuseleko lokutya emanyeneyo kwihlabathi liphela, ikakhulu zilandela iindidi ezintathu zemigangatho:
* **Isiqinisekiso sezinto zoQhagamshelwano lokutya:** I-FDA 21 CFR §177.2600 (e-USA), i-EU 10/2011 (e-EU), kunye ne-NSF/ANSI 51 zicacisa ngokucacileyo ukuba izinto zetyathanga mazingabi natyhefu, zingabi navumba, kwaye zibe nenqanaba lokufuduka kwesinyithi esinzima ≤0.01mg/dm² (zihambelana novavanyo lwe-ISO 6486);
* **Imigangatho yoYilo loCoceko lweMishini:** Isatifikethi se-EHEDG Type EL Class I sifuna ukuba izixhobo zingabi nazindawo zingacocekanga, ngelixa i-EN 1672-2:2020 ilawula ukuhambelana kococeko kunye nemigaqo yokulawula umngcipheko kwimishini yokucubungula ukutya;
* **Iimfuneko Ezithile Zesicelo:** Umzekelo, ishishini lobisi kufuneka lihlangabezane neemfuno zokumelana nokugqwala kwiindawo ezinomswakama ophezulu kunye neendawo ezirhabaxa, kwaye izixhobo zokubhaka kufuneka zimelane nokuguquguquka kobushushu ukusuka kwi -30℃ ukuya kwi-120℃.
II. Iziseko zoCoceko noKhuseleko zoKhetho lwezinto
1. Izixhobo zesinyithi: Ibhalansi yokumelana nokugqwala kunye nokungangcolisi
Beka phambili intsimbi engagqwaliyo ye-316L e-austenitic, enika ukumelana nokugqwala okungcono nge-30% kunentsimbi engagqwali ye-304 kwiindawo ezine-chlorine (ezifana nokucoca i-brine), ukuthintela ungcoliseko lokutya olubangelwa kukugqwala kwesinyithi.
Kuphephe ukusebenzisa intsimbi yekhabhoni eqhelekileyo okanye ii-alloys ezingaqinisekiswanga, njengoko ezi zinto zikhupha ngokulula ii-ion zesinyithi esinzima kwaye azixhathisi kwiiarhente zokucoca ezine-asidi okanye ze-alkaline ezisetyenziswa ekulungisweni kokutya (ezifana ne-1-2% NaOH, 0.5-1% HNO₃).
2. Izinto ezingezizo ezesinyithi: Ukuthobela imithetho kunye nesiqinisekiso zibalulekile
Iirola, imikhono, kunye nezinye izinto zingasebenzisa izinto ze-UHMW-PE eziqinisekiswe yi-FDA, ezinomphezulu ogudileyo noxineneyo, ezinganamatheli lula kwiswekile, igrisi, okanye ezinye iintsalela, kwaye ziyamelana nokuhlanjwa ngoxinzelelo oluphezulu kunye nokugqwala kwezibulali-ntsholongwane.
Izixhobo zeplastiki kufuneka zihlangabezane nemigangatho yezinto eziluhlaza okwesibhakabhaka okanye ezimhlophe ezihambelana noshishino lokutya ukuze kuthintelwe umngcipheko wokufuduka kwemibala (umz., izixhobo zeplastiki ze-igus TH3 series sanitary chains).
III. Imigaqo yokuLungiselela uCoceko loYilo lweZakhiwo
Umahluko ophambili phakathi kwee-roller chains ezicocekileyo kunye nee-industrial chains eziqhelekileyo usekwe kuyilo lwazo "olungafiyo," olufuna oku kulandelayo:
Iimfuno zomphezulu kunye nekona:
Unyango lokupholisha isipili olune-Ra≤0.8μm erhabaxa ukuze kuncitshiswe ukunamathela kweentsholongwane;
Zonke iirediyasi zekona zangaphakathi ≥6.5mm, zisusa ii-engile ezibukhali kunye neengxolo. Isifundo sendlela yokucubungula inyama sibonisa ukuba ukuphucula irediyasi yekona yangaphakathi ukusuka kwi-3mm ukuya kwi-8mm kunciphisa izinga lokukhula kweentsholongwane nge-72%;
Uyilo lokuqhaqha kunye noyilo lweMisele yoMsele:
Isakhiwo seModular esixhasa ukuqhaqha nokuhlanganisa ngokukhawuleza (ixesha elifanelekileyo lokuqhaqha kunye nexesha lokuhlanganisa ≤imizuzu eli-10) ukuze kube lula ukucoca nzulu;
Imijelo yokukhupha amanzi kufuneka igcinwe kwizithuba zeetyathanga ukuthintela intsalela yamanzi emva kokuhlamba. Uyilo oluvulekileyo lwetyathanga elijikelezayo lunokuphucula ukusebenza kakuhle kwe-CIP (ecocekileyo endaweni) ngama-60%;
Ukhuseleko lokutywina oluphuculweyo:
Iindawo zeebheringi zisebenzisa i-labyrinth + lip double seal, zifikelela kwinqanaba le-IP69K lokungangeni manzi elinobukhulu obuyi-≥0.5mm. Amasuntswana aqinileyo kunye nolwelo kufuneka kuthintelwe ukungena; izakhiwo zebholithi eziveziweyo azivumelekanga ukuthintela izithuba ezinemisonto ukuba zicoce iindawo ezingaboniyo.
IV. Iinkqubo Zokusebenza Zokuthobela Umthetho Zokucoca Nokuthambisa
1. Iimfuneko zokuhambelana nokucoca
Iyamelana neenkqubo zokucoca ze-CIP ezinamaqondo obushushu angama-80-85℃ kunye noxinzelelo lwe-1.5-2.0 bar, isusa ngaphezulu kwe-99% yentsalela kwimizuzu emi-5; Iyahambelana nezinyibilikisi zendalo ezifana ne-ethanol kunye ne-acetone, kunye nezibulali-ntsholongwane zodidi lokutya, ezingenazo ii-coating peel okanye ukuguga kwezinto.
2. Imigangatho yoCoceko lweNkqubo zokuthambisa
Kufuneka kusetyenziswe i-lubricant yokutya yodidi lwe-NSF H1, okanye kusetyenziswe isakhiwo esizithambisayo (njengee-rollers ezizithambisayo ezenziwe ngezinto ze-UHMW-PE) ukuze kupheliswe umngcipheko wongcoliseko lwe-lubricant ekutyeni; Ukongeza i-grease engeyiyo yokutya ngexesha lokusebenza kwetyathanga akuvumelekanga, kwaye intsalela ye-lubricant endala kufuneka isuswe ngokupheleleyo ngexesha lokugcinwa ukuze kuthintelwe ukungcoliswa okuthe tyaba.
V. Izikhokelo zoKhetho kunye noLondolozo
1. Umgaqo woKhetho oluSekelwe kwiMeko
2. Amanqaku Aphambili Okugcinwa
* Ukucoca Imihla Ngemihla: Emva kokusebenza, susa intsalela kwizithuba zeepleyiti zetyathanga kunye neendawo eziqengqelekayo. Hlamba ngoxinzelelo oluphezulu uze womise kakuhle ukuze uthintele ukufuma kunye nokukhula kweebhaktheriya.
* Ukuhlolwa rhoqo: Buyisela itsheyini ngoko nangoko xa ubude bayo bungaphezulu kwe-3% yobude obulinganisiweyo. Jonga ngaxeshanye ukuguguleka kwamazinyo e-sprocket ukuthintela ukuguguleka okukhawulezileyo ekusebenziseni iindawo ezindala nezintsha kunye.
* Ukuqinisekiswa kokuthobela imithetho: Phumelela uvavanyo lwe-ATP biofluorescence (ixabiso le-RLU ≤30) kunye novavanyo lomngeni weentsholongwane (intsalela ≤10 CFU/cm²) ukuqinisekisa ukuba imigangatho yococeko iyafezekiswa.
Isiphelo: Ixabiso Eliphambili Lee-Cookie Roller Chains
Ucoceko nokhuseleko lwemishini yokucubungula ukutya yiprojekthi ecwangcisiweyo. Njengenxalenye ephambili yokudlulisa ukutya, ukuthobela imixokelelwane yeroller kumisela ngokuthe ngqo isiseko sokhuseleko lwemveliso yokugqibela yokutya. Ukunamathela kwimigangatho yamazwe ngamazwe ekukhetheni izinto, uyilo lwesakhiwo olungenamthungo, kunye nokugcinwa okusemgangathweni akunciphisi nje kuphela umngcipheko wongcoliseko kodwa kukwafezekisa uphuculo oluphindwe kabini kukhuseleko lokutya kunye nokusebenza kakuhle kwemveliso ngokunciphisa ixesha lokungasebenzi kokucoca kunye nokwandisa ubomi benkonzo. Ukukhetha imixokelelwane yeroller ecocekileyo eqinisekiswe yi-HEDG kunye ne-FDA ngokusisiseko kwakha umqobo wokuqala nowona ubalulekileyo wococeko kwiinkampani zokucubungula ukutya.
