Amawasha e-DIN127 aphakathi kwamawasha ayisicaba acaciswe kabanzi kubunjiniyela bemishini baseYurophu—kodwa abakhethwa ngokungafanele, abacaciswanga kahle, noma badidaniswe ne-DIN 125 noma i-ISO 7089. Sikubone izikhathi eziningi: iklayenti lithumela inqwaba yamabhawodi anamandla aphezulu ukuze lithole indawo esenyakatho ye-DIN2 turbine e-Germany. amawasha anikeziwe awanalo ibanga lokuqina elidingekayo emihlanganweni yeBanga 10.9. Ukulungisa? Sebenza kabusha, ukubambezeleka, nokuhlelwa okungahleliwe. Kungakho ukunemba kubalulekile—hhayi nje ezintweni ezibonakalayo noma ekugcineni, kodwa ekuthotshelweni okujwayelekile.
Iyini Kahle Iwasha i-DIN127?
Iwasha ye-DIN127 iyiwasha eyindilinga, engaqinile engaqinile echazwe yi-German Institute for Standardization (DIN) standard. I-DIN 127 Ingxenye 1. Inobubanzi obuqondile bangaphandle, ububanzi bangaphakathi, nogqinsi—okubalwa njengosayizi webhawodi elivamile—futhi iklanyelwe ngokukhethekile ukusetshenziswa namabhawodi ekhanda eliyihexagon nezikulufu ezivumelana ne-DIN 931, DIN 933, noma ISO 4014/4017. Ngokungafani namawasha aqinile (isb., i-DIN 6796 noma i-DIN 2093), amayunithi e-DIN127 awaphathwa ngokushisa. Ngokuvamile ahlinzekwa ngamafomu ensimbi engagcotshiwe, eyakhiwe ngothayela, noma engafakwanga—futhi indima yawo eyinhloko ukusabalalisa umthwalo, hhayi isenzo sasentwasahlobo noma ukukhiya.
Izici zobuchwepheshe ezibalulekile:
Izinketho zezinto ezibonakalayo: Insimbi (engaqinile, ≤300 HV), insimbi engagqwali (A2/A4), ithusi, i-aluminium Ubuso buqeda: Ithafa, idiphu elishisayo (i-HDG), i-zinc-plated, i-black oxide, i-electropolished Umkhawulo wokuqina: I-Max 300 HV—ibalulekile ekusebenzisaneni nezixhumi ezinamandla kakhulu (iBanga 8.8 nangaphezulu) Isigaba sokubekezelelana: Okuvamile (I-Class N) nge-DIN 2211; ukubekezelela ukujiya ±0.2 mm for d ≤ 16 mm Izinhlobo Ezintathu Zomhlaba Wangempela we-DIN127—futhi Lapho Zihluleka khona
Empeleni, sihlanganisa amawasha e-DIN127 abe yizigaba ezintathu zokusebenza—hhayi ngokwezinga eliphansi elisemthethweni, kodwa ngendlela onjiniyela abawasebenzisa ngayo.
Uhlobo A: Amawasha Amafulethi Ajwayelekile (DIN127-A)
Inguqulo ezenzakalelayo. Isetshenziswa ngamabhawodi afika eBangeni 8.8 emishinini ejwayelekile, impahla yezolimo, kanye nohlaka lwesakhiwo sasendlini. Sincoma lokhu lapho ukucindezela kwendawo kufanele kwehliswe ngaphansi kwamakhanda ebhawudi—kodwa akukho ukulayisha okuguquguqukayo noma ukudlidliza okulindelekile.
Uhlobo B: I-HDG-DIN127 Yonjiniyela Bangaphandle
Amawasha e-DIN127 ane-hot-dip adinga ukunakwa okukhethekile. Ukuhlanganiswa kwe-Zinc kwengeza ~0.05–0.10 mm kugqinsi—futhi uma kungabalwa ngesikhathi kubalwa itorque, amandla okubamba ehla ngo-8–12%. Esikhungweni sethu e-Yongnian, siqinisekisa ukujiya kwe-coating ngokungenisa kazibuthe (DIN EN ISO 2178) ngaphambi kokuthunyelwa. Amaklayenti asebenzisa lawa ngamabhawodi e-ASTM A325 ekuxhumekeni kwebhuloho ngokungaguquguquki abika ukuthi iqanda lixega emijikelezweni yesevisi yeminyaka emi-5.
Uhlobo C: I-DIN127 Engagqwali Yezindawo Ezonakalisayo
I-A4-80 insimbi engagqwali ye-DIN127 washer (nge-DIN 127-2 ngayinye) imelana nesifutho sikasawoti amahora angu->1,000. Kodwa nakhu okuvamise ukuphuthelwa: amawasha angenasici anweba ngokufudumayo ngo-30% ngaphezu kwamabhothi ensimbi ye-carbon. Kuzinhlelo zokusebenza zamabhayisikili ashisayo—njengezintaba ze-solar tracker ezindaweni ezisogwadule—sibone ukulahleka kokucindezelwa kwe-gasket lapho abasebenzisi beqa ukwehlisa ukushisa. Isixazululo sethu? Bhangqa i-A4-80 DIN127 namabhawodi angu-A4-80—futhi ucacise amanani etorque ezingeni lokushisa lokusebenza, hhayi ku-ambient.
Ukulinganisa Akuyona Nje "M6" noma "M12" -Kuwuhlelo
Ubukhulu be-DIN127 bulandela izilinganiso zejiyomethri eziqinile—hhayi amadayamitha angenasizathu. Ngebhawodi engu-M10 (d = 10 mm), ububanzi bangaphakathi bewasha bungu-11.1 mm, ububanzi obungaphandle bungu-22 mm, kanti ukujiya bungu-2.5 mm. Phambuka kulawo manani, futhi uzibeka engcupheni yokulunywa, ukudluliswa komthwalo ongalingani, noma ukuphazamiseka kokubandakanyeka kochungechunge.
Sigcina isitoko esigcwele se-DIN127 kusukela ku-M3 kuya ku-M64—okuhlanganisa izintambo ze-metric ezimahhadla nezicolekileyo—futhi siqinisekisa yonke inkatho ngokumelene nokuhlola kobukhulu be-DIN 2211. Ukweqa okujwayelekile esikuthola nsuku zonke:
Kusetshenziswa i-M12 DIN127 enamabhawodi emicu emihle engu-M12x1.25 (ukungafani kobubanzi bangaphakathi → ukuthintana kwekhanda lomshudo kuphela kumaphoyinti angu-3) Ukufaka i-DIN125 (ijiyile, iqiniswe) lapho kucaciswe i-DIN127 (kudala itorque eningi kanye nokuxebuka kwentambo) Ukucabanga ukuthi "DIN127" kusho ukumelana nokugqwala-lapho izinguqulo zekhabhoni ezingenalutho zigqwala phakathi kwamasonto emoyeni wasogwini Izicelo Ezidinga i-DIN127—Futhi Kungani Ezinye Izindlela Zimfushane
I-DIN127 ayikhethi ezizindeni ezine ezibalulekile:
Ukuxhumana kwensimbi ehlelekile (I-EN 1090-2): Iyadingeka ngaphansi kwe-Eurocode 3 kumajoyinti abhontshiwe lapho amawasha avimbela ukushumeka endaweni ye-flange Isitokwe sikaloliwe (I-EN 15227): Igunyazwe ukukhwezwa kwemoto edonsayo - amawasha angathobeli imithetho adala ukwehluleka kocwaningo. Amamojula wepulatifomu yasolwandle (DNV-OS-F101): Kumele ifanise ubulukhuni bebhawodi ukugwema ukuqhekeka okwenziwe yi-hydrogen enkonzweni emuncu Ozimele bedivayisi yezokwelapha (ISO 13485): Ukuqedwa okungaphezulu Ra ≤ 0.8 µm kuyadingeka—DIN127-A4 ihlangabezana nalokhu ngaphandle kokupholisha kwesibili Amawashi amaza noma i-Bellevilles ngeke ithathe indawo ye-DIN127 lapha. Basebenzela i-physics ehlukene: I-DIN127 ilawula ukucindezeleka okuqinile. Abanye baphatha ukulahleka kokulayisha kuqala okunamandla. Ukuzidida kufana nokusebenzisa isikrufu njengesando—okungenzeka, kodwa okulimazayo.
Kungani u-Hebei Dewell Eletha Amawasha Athembekile e-DIN127
Kwa-Hebei Dewell Metal Products Co., LTD, sikhiqiza amawasha e-DIN127 ngaphansi kolawulo olugcwele lwenqubo—kusuka ekuhlolweni kwebha eluhlaza (ukuhlaziywa kwe-spectrometric nge-DIN EN ISO 14284 ngayinye) kuya ekutholeni isitifiketi sobukhulu bokugcina. Lonke i-oda lifaka izinombolo zokushisa ezilandelekayo, imibiko yokuhlolwa okuqinile, nokuqinisekiswa kokuqina koqweqwe. Siphethe i-inventory kuzo zonke izinhlobo ezingu-12 ze-DIN127—okuhlanganisa i-HDG, i-A2, i-A4, nezinketho zokujiya ngokwezifiso—kanye nomkhumbi osayizi abajwayelekile ngezinsuku ezingu-5–10 emhlabeni jikelele.
Uma ucacisa i-DIN127 yephrojekthi entsha: hlola ibanga lakho lebhawodi, indawo ezungezile, kanye nendlela yetorque kuqala. Bese ufanisa ubulukhuni bewashi, ukuqeda, nejometri—hhayi nje ilebula. Ngoba ngobuqotho bemishini, ingxenye encane kunazo zonke ibeka uphahla lokusebenza kwesistimu.
