Ubona i-spec efana ne-10U1 4U5 16 isikwele se-U-bolt ijikijelwa nxazonke, futhi uma ungajulile kuzisekelo zamapayipi noma i-bracing yesakhiwo, ingase ibe i-hieroglyphics. Iqiniso liwukuthi, ngisho nabanye abafana abanolwazi bayakhubeka becabanga ukuthi i-16 ibhekisela ngokuzenzakalelayo kububanzi bebhawudi-akunjalo. Lokho kuvame ukuba yi-square dimension, ububanzi obunqamula amafulethi okugoba kwe-U-bolt. Inyama yangempela iku-10U1 kanye ne-4U5, okuvamise ukuba ubunikazi noma ikhodi yesifunda yezilinganiso zomthwalo kanye nochungechunge lwe-dimensional. Ake sihlaziye ukuthi yini oyifunayo ngempela uma othile ekucela lokhu.

Ukuqopha isobho le-Alphanumeric

Kunjalo, 10U1 futhi 4U5. Kumakhathalogi amaningi, ikakhulukazi avela ezindaweni ezinkulu zokukhiqiza njengesifunda sase-China sase-Yongnian, i-U isho uchungechunge lwe-U-bolt. Inombolo eyanduleleyo ivamise ukuhlobana nesigaba sokusebenza noma sesitayela. I-10U1 ingabonisa uchungechunge lomsebenzi osindayo, mhlawumbe kumadayimitha amapayipi amakhulu noma imithwalo yokuzamazama komhlaba ephakeme, kuyilapho i-4U5 ingase ibe uchungechunge olulula. U-1 no-5 cishe amakhodi okubuyekezwa noma esitayela esincane. Ngeke ukuthole lokhu kumazinga e-ASTM; kukhulunywa ngefekthri. Ngikhumbula ngikhipha izinwele zami ngibheka i-6U3 komunye umphakeli one-CL-150 komunye - kwavela ukuthi ayefana ngokusebenza, amalebula ahlukile. Njalo, cela njalo umdwebo wobukhulu.

Isikwele esingu-16 sicace kakhudlwana. Lokhu kucacisa i-U-bolt yesikwele, lapho ukugoba kuyi-engeli ye-90-degree yangempela, hhayi eyindilinga. I-16 ubukhulu buka-A, ububanzi bangaphakathi buka-U, ngokuvamile ngamamilimitha. Ngakho-ke, ingu-16mm ukusuka ngaphakathi komlenze owodwa kuya ngaphakathi komunye. Lokhu kubalulekile ekufakeni phezu komugqa noma isiteshi. Iphutha elivamile uku-oda i-U-bolt yesikwele esingu-16mm ukuze ibambe into ewugqinsi engu-16mm—ngeke ilingane. Udinga imvume, ngokuvamile ama-mm ambalwa ngaphezulu.

Yini engekho lapha? Ubude bomlenze (ubukhulu be-L), usayizi wentambo nephimbo (isb., M12 x 1.75), okokusebenza (insimbi ye-carbon steel, i-hot-dip galvanized, 304/316 stainless), kanye nesiphetho. Ikhodi ye-alphanumeric ayivamisile ukufaka konke lokho. Kuyiphoyinti lokuqala, hhayi ukucaciswa okuphelele. Lokhu ngikufunde kabuhlungu emsebenzini wokuhlanzwa kwamanzi; sithole amabhawodi angu-10U1 esizeni, kodwa ayeyinsimbi engenalutho lapho sidinga i-hot-dip galv. Konke ukuthunyelwa kwenqatshiwe.

Izilinganiso Ezibucayi Abakutsheli

Ubude bomlenze yikho konke okumele kufakwe. Uma imilenze imifushane kakhulu, amantongomane akho ngeke ahlanganyele ngokugcwele. Isikhathi eside kakhulu, futhi umosha izinto ezibonakalayo futhi okungase kube sengozini yokuqina-umlenze omude, omncane ungagoba ngaphansi kwe-torque. Ukuze uthole i-U-bolt yesikwele, udinga futhi ubukhulu B, ukuphakama kwangaphakathi kusuka phansi kokugoba kuya ekuqaleni kwemicu. Lokhu kunquma ukuthi kungakanani okubalulekile ongahlanganisa. Umthetho ojwayelekile: ku-clamp yepayipi, ubukhulu bakho be-B kufanele bube bukhulu kunepayipi O.D. kanye nobukhulu besihlalo sehhashi noma umcamelo wakho, kanye negebe lamantongomane newasha.

Ukucaciswa kochungechunge kungenye isithiyo. Isikwele esingu-16 asisho lutho ngobubanzi benduku. Kungaba i-M10, i-M12, noma i-M8 ehlanganisa ukugoba kwesikwele esingu-16mm. Umthamo womthwalo uncike kulokhu. Okwe-a i-clamp yepayipi ukuvikela umugqa wama-intshi angu-4 weshejuli engu-40, intambo engu-M10 kubhawodi engu-10U1 ingase icaciswe ngaphansi kwemithwalo eguquguqukayo. Udinga amandla aqinile kanye nedatha yokulayisha ubufakazi. Abakhiqizi abahloniphekile, njengaye I-Handan Zitai Fetesser Comment Co, Ltd. esekelwe kuleso sisekelo sokukhiqiza esikhulu se-Yongnian, ngokuvamile ihlinzeka ngala mashadi. Indawo yabo, zitasteners.com, inamakhasi obuchwepheshe ahloniphekile lapho ungahlola khona amakhodi ochungechunge ngokumelene nezakhiwo zangempela zokukhanda.

Izinto kanye nesiphetho akuyona imininingwane engasho lutho. Embonini yamakhemikhali, leyo bolt engu-4U5 kungcono ibe ngu-316 engenasici. Kuhlelo lokusebenza lwe-HVAC yasogwini, idiphu eshisayo efakwe i-ASTM A153 ayinakuxoxiswa. Ikhodi 10U1 ingase ibe nezinto ezizenzakalelayo, kodwa kufanele uqinisekise. Ngibone i-U-bolt ithathwa isho ijenerikhi, ifakwe uthayela ngokuthengwa, okuholela ekuhlulekeni kokugqwala ngaphambi kwesikhathi kuphrojekthi yegalaji lokupaka. I-spec kumele isho ngokucacile ibanga lezinto ezibonakalayo kanye ne-coating.

Isicelo Somhlaba Wangempela Nokucatshangelwa Komthwalo

Ngakho-ke, usebenzisa lokhu ukuhlanganisa i-clamp clamp. I-U-bolt iyingxenye eyodwa nje. Unesihlalo (ucezu olubeka ipayipi), amantongomane, futhi ngokuvamile ipuleti lokusekela noma umzila. Umsebenzi we-U-bolt ukudala amandla okubamba ngaphandle kokukhubazeka. I-U-bolt eyisikwele, njengalesi sikwele esingu-16, ihlala ingqubuzana ne-square beam, ivimbela ukuzungezisa-i-U-bolt eyindilinga ngezinye izikhathi ingaphenduka ngesikhathi sokuqina, okuyiphupho elibi ezindaweni eziqinile.

Uchungechunge lwamakhodi 10U1 vs. 4U5 cishe ahlotshaniswa nokulayisha izilinganiso. Ngokuhlangenwe nakho kwami, inombolo ephakeme ehamba phambili ngokuvamile isho ububanzi benduku obukhulu kanye nerediyasi yokugoba esindayo, eklanyelwe imithwalo ephakeme yokuzamazama komhlaba noma eshisayo. Awukwazi nje ukuwashintsha. Emsebenzini wokubuyisela imali ngonyaka odlule, sashintsha amabhawodi angu-4U5 safaka u-10U1 kwiluphu yokwandisa ulayini wesitimu, kodwa kudingeke ukuthi sithuthukise nawo wonke ukuhlanganiswa kwesihlalo sehhashi, njengoba ibhawodi elisindayo lalidinga isihlalo sehhashi eliwugqinsi ukuze lisabalalise umthwalo ngendlela efanele ekufakweni kwepayipi.

I-torque ibaluleke kakhulu. Ukudonsa ngokweqile i-U-bolt yesikwele kungagcizelela ukugoba, kudala iphuzu lokuphuka. I-under-torquing, futhi ipayipi lakho liyashelela. Inani letorque lincike kusayizi wentambo, iphimbo, nokokusebenza. Akukho okufana nosayizi owodwa. Udinga ithebula letorque yomkhiqizi kuleyo khodi yomkhiqizo othile. Amatafula ajwayelekile akungenisa e-ballpark kodwa angehla ngo-20%.

I-Sourcing kanye ne-Gotcha Factors

Uma uthola okuthile ngekhodi efana nalena, kungenzeka ukuthi usebenzelana nesistimu ethile yomphakeli. Kuyakhokha ukuya ngqo kumkhiqizi onokusekela konjiniyela. Inkampani efana I-Handan Zitai Fastener, uma kubhekwa indawo yayo enkabeni yemboni ye-fastener yase-China enezixhumanisi eziqinile zezokuthutha, ngokuvamile inalawa makhodi afakwe kumephu yemininingwane yokukhiqiza enemininingwane. Ukunethezeka kukhona, kodwa isibopho sikuwe ukuthi unikeze umongo ogcwele wohlelo lokusebenza.

I-gotcha enkulu ukubekezelelana. Ubukhulu obuyisikwele obungu-16mm bungaba nokubekezelela +/- 1mm. Uma isiteshi sakho sensimbi siqinile ngo-16mm, ibhawudi elingu-15mm lizoxega, futhi elilodwa liku-17mm ngeke lilingane. Kuzinhlelo zokusebenza ezibucayi, udinga ukucacisa ukubekezelelana okuqinile, okungase kukususe entweni yesitoko kuya ekusebenzeni ngokwezifiso. Izikhathi zokuhola nezindleko ziyashintsha.

Enye inothi elisebenzayo: ama-U-bolts ayisikwele, ikakhulukazi osayizi abakhulu, angaba nokuchezuka okuncane kusuka ekujikeni okuphelele kwama-degree angama-90 ngenxa yenqubo yokufoja nokupholisa. Kuyafaneleka ukucela ukubekezelelana okuqondile / kwe-camber. Kuye kwadingeka ngibuyisele inqwaba lapho imilenze iqhuma khona ngamadigri angu-3, ​​okwenza kube nzima ukuqalisa amantongomane ngokulinganayo. Umhlinzeki omuhle uzokuhlola lokhu.

Ukuhlanganisa Konke

Ngakho-ke, emuva kokuthi Kuwumbuzo ongaphelele. Ukuze uyicacise kahle, ungayinweba ibe yinto efana nalena: I-U-bolt yesikwele, uchungechunge 10U1 (noma 4U5), ukuze uthole isigxivizo sepayipi esindayo/esilula. Ububanzi bangaphakathi (A): 16mm. Ubude bomlenze (L): [isb., 120mm]. Uchungechunge: [isb., M12 x 1.75]. Material: [isb., Grade 8.8 steel]. Qeda: [isb., i-Hot-dip efakwe amagalani]. Izosetshenziswa nesihlalo esihambisanayo sepayipi O.D. [X].

Ikhodi yochungechunge iyisinqamuleli salabo abajwayele umugqa womkhiqizo. Kuwo wonke umuntu, kuwugibe. Ngaso sonke isikhathi yehlisa ibe ubukhulu bomzimba kanye nezidingo zokusebenza. Sebenzisa ikhodi njengereferensi lapho ukhuluma nomphakeli wakho, kodwa ungalokothi njengokucaciswa komdwebo noma i-PO.

Ekugcineni, ukuthola ilungelo U-u-bolt imayelana nokuqonda uhlelo eyingxenye yalo. Ibhawodi ayisebenzi yodwa. Lobo bukhulu besikwele esingu-16 kufanele budlale kahle ngensimbi yakho yokwesekwa, isilinganiso esingu-10U1 kufanele sihambisane nezibalo zakho zomthwalo, futhi okubalulekile kufanele kuphile endaweni okuyo. Kuyingxenye encane, kodwa ukuyicacisa okungalungile kungaholela ekusebenzeni kabusha okuningi-ngethembe, bengiwumfana onomthelela we-wrench emvuleni, ngizama ukwenza ibhawodi elingalungile lilingane.
