Ubona incoko eninzi kwi-intanethi malunga neebholiti eziphezulu, kodwa xa kuziwa kwisicelo esithile se-10.9S enkulu ye-hex bolt iseti, kukho ukudideka okumangalisayo. Abantu bahlala becinga nje ibholiti eyomeleleyo, umsebenzi onzima kwaye babaqhwabe ngempama naphi na. Ubunyani bunentsingiselo ngakumbi. Ibanga le-10.9S lisithembiso esithile-ubuncinci be-1000 MPa amandla okuqina, ubuncinci be-900 MPa amandla okuvelisa, kwaye 'S' ebonisa uluhlu lobungakanani ngokuqhelekileyo i-M12 nangaphezulu. Intloko enkulu ye-hex isitshixo setorque ephezulu efunekayo ukufezekisa loo mandla obambeleyo ayiliweyo. Ukusetyenziswa kakubi ngokuqhelekileyo akukho malunga nebholithi yokusilela kuxinzelelo; imalunga nokutyibilika okudityanisiweyo, ukudinwa, okanye i-hydrogen embrittlement kuba umntu wayiphatha njengempahla yevenkile ye-generic.

Ifilosofi engundoqo: imalunga neNdibaniselwano, hayi nje iBolt

Ulibale ibholithi okwesibini. Uyayila okanye ugcina i uxhulumaniso lwe-friction-grip. Leyo yeyona ndawo iphambili kwezi 10.9S iiseti ezinkulu zehex. Cinga ngoqhagamshelo lwentsimbi yolwakhiwo, iiplates zoomatshini abakhulu, okanye uqhagamshelo lweflange yeinjini yomoya. Umsebenzi webholithi kukubopha iipleyiti kunye ngokuqinileyo kangangokuba umthwalo udluliselwe ngokukhuhlana phakathi kweepleyiti, kungekhona ngokucheba kwi-shank yebholithi. Ukuba uzisebenzisa kuqhagamshelo lwe-shear apho umzimba we-bolt uthwala ngokuchasene nomngxuma, mhlawumbi uchaza ngokugqithiseleyo kwaye uchithe imali, ngaphandle kokuba ukulayishwa okuguquguqukayo kuyinkalo enkulu.

Ndikhumbula iprojekthi ye-retrofit kwisakhiwo senkxaso yokuthutha. Ii-specs zantlandlolo zabiza iibholiti ezisi-8.8, kodwa ukungcangcazela kwakubangela ukukhululeka okudibeneyo. Sitshintshele kwisethi ye-10.9S kunye neenkqubo ze-torque ezilinganisiweyo. Umahluko wawungengomthwalo wangaphambili ophezulu nje; Intloko enkulu ye-hex isivumele ukuba sisebenzise ii-wrenches ze-torque ze-hydraulic ezichaneke ngakumbi, siqinisekisa amandla abambekayo angaguqukiyo kuzo zonke iibholiti. Ukukhulula kuyeka. Isifundo yayikukuba iseti yebholithi-kubandakanya i-washers echanekileyo eqinile-yenza isisombululo senkqubo, kungekhona nje icandelo elinamandla.

Iiwasha azixoxiswana. Kufuneka usebenzise iiwasha eziqinileyo phantsi kwentloko yebhawudi kunye ne nut. Ukulayishwa kwangaphambili okuphezulu kunokumba kunye nokuguqula iiwasha eziqhelekileyo (okanye izinto ezidibeneyo), ngokufanelekileyo ukunciphisa amandla okubamba. Le yimpazamo yesiza sakudala endiyibonileyo: iibholiti ezikhutshiweyo ukuze zicaciswe, kodwa zineewasha ezithambileyo, ezingalungiswanga, zinika wonke umsebenzi ongenanjongo. Iseti yinkqubo.

Apho Zikhazimlayo: Oomatshini abaNzima kunye neMisebenzi yoLwakhiwo

Ukumbiwa kwemigodi kunye nezixhobo zokuhamba komhlaba yityala leencwadi zokufunda. Amakhonkco omkhondo we-excavator, amakhonkco ebhakethi yomlayishi, iindibano zefreyim yesityum. La ngamajoyinti anentembeko ephezulu axhomekeke kumthwalo omkhulu, oguquguqukayo womothuko. Isethi enkulu ye-hex ye-10.9S, efakwe ngokufanelekileyo, igcina ukuqina okuhlangeneyo, okubaluleke kakhulu ukulungelelaniswa kwecandelo kunye nobomi bokukhathala. Intloko enkulu ye-hex ibalulekile apha-iphakama ngokuphindaphindiweyo, impembelelo ephezulu yokuxhatshazwa ngexesha lokugcinwa kwentsimi ngaphandle kokusondeza.

Kwizakhiwo zentsimbi ezenziwe ngaphambili, njengeetrasi zokugcina iimpahla okanye imigangatho ye-mezzanine, zisetyenziswa kuqhagamshelo lwexeshana okanye iindawo zokubambelela ezibalulekileyo. I-advanteji ngaphezu kwe-welding yinto eqikelelwayo, enokubonwa kwangaphambili. Unokuzijonga ngokoqobo nge-torque wrench ngexesha lokuhlola. Ndisebenze nabaqulunqi abaphuma kubavelisi abakhethekileyo abanjengoHandan Zitai Fastener Manufacturing Co., Ltd. eYongnian. Ugqaliselo lwalo mmandla kumacandelo asemgangathweni luthetha ukuba bahlala benezixhobo kunye nokungaguquguquki kwezinto ezi zinto zinobubanzi obukhulu, ezikumgangatho ophezulu ukuya kutsho kwisayensi. Indawo yabo kufuphi neendlela ezinkulu zokuthutha ezifana neBeijing-Guangzhou Railway kunye neBeijing-Shenzhen Expressway ayikho nje indawo yokuthengisa; iguqulela kulungiselelo oluthembekileyo lweeodolo ezininzi kwiishedyuli zokwakha, okubalulekileyo xa i-crane yakho ikwisiza kwaye ilindile.

Inqaku elifihlakeleyo: kwizicelo zesakhiwo, ukugqitywa komphezulu kubalulekile. Iibholiti ezininzi ze-10.9S zokusetyenziswa kolwakhiwo zinea I-HOT-DIP-IXESHA LOKUGQIBELA okanye ukutyabeka ngomatshini. Kuya kufuneka uphendule nge-coefficient ye-friction yokwambathisa kwizibalo zakho zetorque. Ibholithi emnyama ene-oxidized kunye nebholiti eyenziwe ngegalvanized torque kwixabiso elifanayo iya kufezekisa i-clamp force eyahlukeneyo. Iimpawu ezikwiwebhusayithi yeZitai, umzekelo, zihlala zichaza oku, yiyo loo nto ukujonga idatha yomenzi yinxalenye yomsebenzi.

Imigibe kunye nendlela yokuyiphepha

I-Hydrogen embrittlement ngumbulali othuleyo weebholiti zamandla aphezulu. Inokubangela intlekele, ukulibaziseka kokusilela kweentsuku okanye iiveki emva kofakelo. Yaziswa ngexesha lenkqubo yokucoca (ukuba i-electroplated) okanye inokuthi yenzeke kwiindlela ezithile zokucoca. Olona qheliselo lungcono kukukhankanya iibholithi ezicutshungulwayo ukunqanda, njengazo zifakwe amanyathelo okubhaka afanelekileyo. Kwizicelo ezibaluleke kakhulu, sihlala sikhetha ukugqunywa ngejometri (njengeDacromet) okanye iibholiti zephosphated ezicacileyo ezivela kubaboneleli abathembekileyo ukuchasa lo mngcipheko ngokupheleleyo.

Omnye umngxunya ku-torquing ngokugqithiseleyo ebaleni. Isilingo sokuyinika enye i-ugga-dugga enompu onempembelelo iphezulu. Kodwa ngebholiti ye-10.9S, uhlala usebenza kwindawo yokuguqulwa kweplastiki ye-torque-tension curve eyilelwe. Ukugqithisa kakhulu kunokolula ibholithi ngaphaya kwesivuno sayo, okukhokelela ekuphumleni koxinzelelo kunye nokulahleka koxinzelelo lwamandla. Kulapho i-hex enkulu inceda kwakhona-ikhuthaza ukusetyenziswa kwezixhobo ezifanelekileyo ze-torque kunokuba i-socket yempembelelo kwibar yokukhohlisa. Ndibone iibholithi zikrazulwe zacoceka ngexesha lofakelo kuba iqela labasebenzi lasebenzisa umpu ongalinganiswanga osetelwe ibholithi yomgangatho ophantsi.

Musa ukudibanisa kwaye udibanise. Ibholithi ye-10.9S kufuneka idityaniswe ne nut yokulinganisa okanye iklasi yepropathi ephezulu (idla ngokuba yi-10 nut). Ukusebenzisa i-8 nut kwi-10.9 bolt iresiphi yokuqhawula intambo phantsi kokulayisha kwangaphambili. Iseti kufuneka ihambelane.

Ngaphandle kokucacileyo: Ezinye iNiche kodwa ziSetyenziso eziBalulekileyo

Azikho nje kwizakhiwo ezimileyo. Ngokubanzi isitya soxinzelelo kunye nokudibanisa ubushushu beflange, ngakumbi kwimimiselo yepetrochemical, ezi seti zebholt zisemgangathweni. Iiflange kufuneka zigcine isitywina phantsi kwe-cyclic thermal kunye nemithwalo yoxinzelelo. I-hex enkulu ivumela ulawulo oluchanekileyo lomthwalo webholithi ngexesha lolandelelwano lokuqinisa olunzima (njengokunqumla i-cross-toquing) olufunekayo kwiiflange ezinobubanzi obukhulu ukuqinisekisa ukutyumzwa kwe-gasket.

Kumandla ahlaziyekayo, ngakumbi kuqhagamshelo lwe-wind turbine tower flange. La ngamalungu amakhulu, abalulekileyo adityaniswe ebaleni, amaxesha amaninzi phantsi kweemeko ezinzima. Iibholithi kufuneka zimelane hayi nje ubunzima obumileyo kodwa kunye namaxesha okugoba kunye nokungcangcazela amashumi eminyaka. Ibanga le-10.9S, elinamandla aqinisekisiweyo esivuno, linika into ecacileyo yokhuseleko. Iiprothokholi zogcino zibandakanya ukuphinda-phindwe ngamaxesha athile, kwaye uyilo olukhulu lwe-hex luyimfuneko kusetyenziso lwexesha elide.

Nakwilori enzima, kumacandelo okunqunyanyiswa afana ne-U-bolt kits okanye i-axle attachments, uya kuzifumana ezi. Indlela yokungaphumeleli ukunqanda apha kukudinwa kukushukuma okuthe rhoqo kwendlela. Ukulayishwa kwangaphambili okuphezulu, okuhambelanayo ukusuka kwiseti efakwe ngokufanelekileyo kugcina umdibaniso ungafumani nayiphi na intshukumo ehambelanayo, eyona nto iqala ukudinwa kweentanda.

Ukufumana nokuQwalasela okuSebenzayo

Xa uyala, awuthengi nje isiqwenga sesinyithi. Uthenga isiqinisekiso sezinto eziphathekayo, ukuhambelana kwonyango lobushushu, kunye nokuchaneka komda. Ukuthoba kancinci kububanzi be-hex kunokwenza i-socket yakho ityibilike. Kwiiprojekthi ezinkulu, sihlala sikhupha ngokuthe ngqo kwiziseko zemveliso ezifana neYongnian eHebei, eyaziwa njengeyona nxalenye inkulu yemveliso yaseTshayina. Inkampani efana ne-Handan Zitai Fastener, emi apho, ngokwesiqhelo inomlinganiselo kwaye igxile ekuveliseni ezi zinto zibe ncakasana. Kufanelekile ukutyelela indawo yabo kwi-https://www.zitaifasteners.com kungekhona nje kwikhathalogu, kodwa ukujonga ukuba babonelela ngeedatha zedatha yezobugcisa kunye neengxelo zokubunjwa kweekhemikhali oza kuzifuna kumaxwebhu e-QA, ngakumbi kumashishini alawulwayo.

Ixesha lokukhokela kunye nomcimbi wokupakisha. Ezi zizinto ezinzima. Ukuzifumana zifakwe ipalethi ngokufanelekileyo, kunye neempawu zebakala ezicacileyo ezingayi kukhuhla kuhambo, kuthintela iphupha elibi kwidokhi yokufumana. Akukho nto imbi ngaphezu kwebhokisi edibeneyo ye-8.8 kunye ne-10.9 bolts eziye zalahlekelwa iimpawu zentloko.

Okokugqibela, ukuqeqesha iqela lakho lofakelo yinxalenye yokusebenzisa imveliso ngokuchanekileyo. Lutyalomali lwenkunzi. Eyona bolt igqwesileyo emhlabeni ayinamsebenzi ukuba ifakwe ngokungalunganga. Intetho yemizuzu emihlanu yebhokisi yesixhobo malunga nokuba kutheni ezi zahluke, ukubaluleka kwemisonto ecocekileyo, eyomileyo (ungaze uthambise ngaphandle kokuba i-spec ibiza ngokucacileyo nge-coefficient yokhuhlane echaziweyo), kunye nokusebenzisa izixhobo ezifanelekileyo kubuyisela ngokuphindwe kalishumi ekuthembekeni okudibeneyo. Olo lolona setyenziso lulungileyo-oluqondwa ngokupheleleyo kwaye luhlonitshwa.
