Iibholiti ze-10.9S: izicelo ezizinzileyo kwimizi-mveliso? 

Makhe sinqumle i-fluff yokuthengisa. Xa usiva iibholiti ze-10.9S kunye nozinzo kwisivakalisi esifanayo, ukusabela kwangoko kudla ngokuthandabuza. Ngokuqhelekileyo kuhlanjululwa ngokuluhlaza, akunjalo? Omnye umenzi ubetha i-eco-ileyibhile kwi-fastener ephezulu ngenxa yokuba iyindlela. Kodwa emva kweminyaka kumgangatho wevenkile nakwizicelo zentsimi, ndiyibonile incoko itshintsha. Kuncinci malunga nebholithi ngokwayo eluhlaza kwaye ngaphezulu malunga nendima yayo ekwenzeni iinkqubo zoshishino ezizinzileyo. Umbuzo wangempela awukho ukuba i-bolt ye-10.9S izinzileyo, kodwa indlela iimpawu zayo ezithile-xa zichazwe ngokuchanekileyo kwaye zisetyenziswe-zinokuba negalelo kubomi obude, ukusebenza kakuhle, kunye nokugcinwa kwezibonelelo kwizakhiwo kunye noomatshini. Kulapho i-nuance, kunye nomsebenzi wangempela, uqala.

Umqolo Ongaqondwayo

Okokuqala, ukujonga okwenyani. Ibholithi ye-10.9S ayingomlingo. I-10.9 ibonisa ubuncinci bamandla obunzima be-1000 MPa kunye nomlinganiselo wesivuno we-0.9. I-S ibonisa ukuba yibholithi yolwakhiwo yoqhagamshelo lokubamba ukukhuhlana. Ibango layo lokuzinza liqala ngomsebenzi walo: ukunyanzelisa amalungu adityanisiweyo ngokuqinileyo kangangokuba umthwalo udluliselwe ngokukhuhlana, hayi ukuchetywa kwebholiti. Oku kuthetha ukuba ungasebenzisa iibholiti ezimbalwa xa kuthelekiswa nohlobo loqhagamshelo. Iziqhoboshi ezimbalwa zithetha imathiriyeli encinci, ukugrunjwa okuncinci, kunye noyilo olunokuba khaphukhaphu, olusebenzayo ngakumbi. Ndikhumbula iprojekthi ye-retrofit kwi-gantry yokuthutha apho ukutshintshela kwi-10.9S eyilwe ngokufanelekileyo i-friction-grip joint yanciphisa ukubalwa kwebholithi ngama-30%. Oko kukugcinwa ngokuthe ngqo kwezinto, kodwa kuphela ukuba uyilo kunye nokuphunyezwa akunasiphako.

Umngxunya, kwaye ndiyibonile le nto ngokwam, ibaphatha njengeebholiti eziqhelekileyo zokuqina. I-angle yokuzinza iyawa ukuba awuphumeleli amandla afunekayo okubamba. Oko kuthetha ukuba izitshixo zetorque ezilinganisiweyo, ukulungiswa okufanelekileyo komphezulu (ukucoca isikali sokusila, ukusebenzisa isikali esichanekileyo. izicelo zoshishino oluzinzileyo), kunye nokuthotyelwa ngokungqongqo kwiinkqubo zokuqinisa. Ndibone amajoyinti engaphumeleli ekuhlolweni ngenxa yokuba abasebenzi basebenzise i-wrench yempembelelo ebekwe kwi-max endaweni yesixhobo esilinganisiweyo. Iibholithi bezilungile, kodwa ijoyinti yaphazamiseka ukususela kusuku lokuqala, nto leyo eyakhokelela ekugcinweni kwangaphambi kwexesha, inkunkuma, kunye nechasana ngqo lesenzo esizinzileyo.

Apha kulapho ukukhangela kubaluleke khona. Ayizizo zonke iibholiti ze-10.9S ezenziwe zilingana. Isinyithi esingqinelanayo kunye nokuchaneka komda akuxoxiswana kumandla okubamba okuqikelelweyo. Siye saqhuba kakuhle ngeebhetshi ezivela kubavelisi abakhethekileyo kwimimandla enenkqubo enzulu yokuvelisa, njengendawo ejikeleze iHandan eHebei. Kukho ukuxinana kobuchule apho. Umzekelo, i-Handan Zitai Fastener Manufacturing Co., Ltd., esebenza kweso siseko siphambili semveliso, ihlala ibonelela ngeeprojekthi apho ukulandelelwa kunye nomgangatho ongaguqukiyo uchaziwe. Indawo yabo kufuphi neendlela ezinkulu zothutho ezifana ne-Beijing-Guangzhou Railway ayikho nje inzuzo ye-logistics; inika ingcebiso ekudityanisweni kothungelwano lonikezelo lwemizi-mveliso olukhulileyo, oluthi, ngokwembono yomjikelo wobomi, lunciphise ukukhutshwa kothutho kwii-odolo ezininzi.

Ubomi obude ngaphezu koTshintsho

Uzinzo lokwenyani kushishino luhlala luthetha ukwakha izinto ezihlala zihleli. Ukumelana nokugqwala kwendibano ye-bolt ye-10.9S yinto yokwenza okanye ikhefu. Ibholithi ngokwayo, ngokwesiqhelo intsimbi ye-carbon alloy, ichaphazeleka kukurusa. Ngoko ke, isambatho ayisongezo; ibalulekile kubomi benkqubo. Ukushenxiswa kwi-cadmium plating yendabuko (inetyhefu) ukuya kwiingubo ze-zinc-flake (ezifana neGeomet okanye i-Dacromet) kukusingqongileyo okuthe ngqo kunye nokuphuculwa komsebenzi. Ezi zambatho zibonelela ngokugqwesileyo kokumelana nomhlwa ngaphandle kweentsimbi ezinzima.

Sikuvavanye oku kwizakhiwo zesikhululo sombane sangaphandle. Iiseti ezimbini ezifanayo zoqhagamshelo, enye ineebholiti ezisemgangathweni ze-10.9S zediphu, enye ineentsimbi ezigqunywe nge-zinc kumthengisi onjengeZitai Fasteners. Ezi zitshizi zediphu zibonise umhlwa omhlophe kunye nenye ebomvu erhubuluzayo emva kweenyanga ezili-18 kwindawo yoshishino. Ibhetshi ye-zinc-flake? Isabonakala icocekile, kungekho zimpawu zokukhuhlana komphezulu. Uhlalutyo lweendleko zomjikelo wobomi luthande olu lwamva kakhulu-akukho mfuneko yokutshintshwa kwangethuba, akukho mngcipheko wokuhlutha, kunye nolondolozo oluncinci kakhulu. Yinto ebambekayo leyo isicelo soshishino oluzinzileyo: Ukucacisa isibophelelo esifanelekileyo esikhuselekileyo sokwandisa amaxesha eenkonzo kunye nokuphepha inkcitho.

Kodwa nantsi iinkcukacha ezihlala ziphosakele: iiwasha. Ngoqhagamshelo lwesakhiwo se-10.9S, kufuneka usebenzise iiwasha eziqinileyo (HRC 35-45 ngokuqhelekileyo). Umsebenzi wabo kukusasaza i-clamping force kunye nokuthintela intloko ye-bolt / nut ekufakeni kwizinto ezidibeneyo, ezinokubangela ukulahlekelwa kwangaphambili. Ukuba usebenzisa iwasha ethambileyo, umdibaniso uyaphumla ngokuhamba kwexesha. Ndibizwe ukuba ndifumanise ukusilela kwebholt ebekukusilela ngewasha. Ilungu likhululwe, likhokelela ekukhathazeni, ukunxiba, kwaye ekugqibeleni, kubizwe ukutshintshwa ngokupheleleyo. Ukusebenzisa iikhomponenti ezichanekileyo, eziqinileyo yinkcukaca encinci enefuthe elikhulu kwimfezeko yexesha elide kunye nokuzinza kwendibano.

Ukunika amandla ukuKhanya kunye nokusebenza ngokufanelekileyo

Apha kulapho ibholithi ye-10.9S iba sisixhobo soyilo oluzinzileyo olubanzi. Kwizixhobo eziphathwayo-cinga iinacelles ze-wind turbine, iifreyimu zebhetri yemoto yombane, okanye ukwakhiwa kweemodyuli-ubunzima bubotshelelwe ngokuthe ngqo ekusebenziseni amandla. I-high clamping force ye-10.9S bolts ivumela iinjineli ukuba zisebenzise amandla aphezulu, iintsimbi ezincinci okanye i-alloys ye-aluminium kumalungu, kuba umthwalo usasazwa ngokufanelekileyo ngokukhuhlana.

Umzekelo obambekayo: iprojekthi ebandakanya iiyunithi zeziko ledatha yeemodyuli. Uyilo lubize iifreyimu ze-aluminiyam zokonga ubunzima ngexesha lothutho. Umceli mngeni ibikukudala amalungu aqinileyo, athembekileyo aqhotyoshelweyo kwialuminiyam, ethanda ukurhubuluza. Isisombululo besisebenzisa iibholiti ze-10.9S ezinobukhulu obukhulu bokuhlamba iiwasha kunye nolandelelwano lokuqinisa olulawulwayo ekulayisheni kwangaphambili okuchanekileyo. Oku kunciphisa uxinzelelo lwendawo kwi-aluminiyam kunye nokugcinwa kwamandla okubamba. Isebenzile. Kwavumela ukusetyenziswa kwesixhobo esinamandla ngakumbi kodwa esinokuphinda sisetyenziswe (i-aluminium) kwi-design lightweight, kunye nenkqubo ye-bolt iqinisekisa ixesha elide. Ibholithi iququzelele ukhetho oluzinzileyo lwemathiriyeli.

Nangona kunjalo, oku kutyhala ibholi kumda wayo. Ujongene nokwandiswa kwe-thermal coefficients phakathi kwentsimbi ye-bolt kunye, yithi, i-aluminium. Kwiimeko zobushushu obujikelezayo, oku kunokubangela ukuguquguquka kokulayisha kwangaphambili. Sifunde oku ngendlela enzima kwiprototype yokuqala yesakhiwo sokulandelela ilanga. Umjikelo wobushushu bemihla ngemihla ubangele ukwandiswa okwaneleyo okwaneleyo ukukhulula kancinane amanye amalungu, okukhokelela ekudakaleni okuvakalayo. Ukulungiswa kwakungeyobholithi eyomeleleyo, kodwa uyilo oluhlaziyiweyo oludityanisiweyo oluneebholiti ezininzi kwindawo esezantsi kancinane yokulayishwa kwangaphambili komntu ngamnye ukwenza inkqubo ezinzileyo. Yayisisifundo kwindlela yokucinga—ibholithi yinxalenye nje enye yenkqubo entsonkothileyo ye-ecosystem.

Umbuzo wokuReusability kunye nokuphela koBomi

Umbuzo oqhelekileyo: ungaphinda usebenzise iibholiti ze-10.9S? Impendulo esemthethweni, egcinayo kwiikhowudi ezininzi zobunjineli ithi hayi, ngakumbi kuqhagamshelo olubalulekileyo lwesakhiwo. Inkxalabo kukuba i-deformation yeplastiki ngexesha lokuqiniswa kokuqala kunye nomonakalo onokwenzeka wentambo ngexesha le-disassembly compromise performance. Ngokwesiqhelo, kwizakhiwo ezingabalulekanga, eziziisekondari, ndibone ukusetyenziswa kwakhona ngononophelo kunye nokuhlolwa okungqongqo-ukukhangela intambo yokugalela, intamo, kunye nokusebenzisa igeyiji yomsonto.

Kodwa ngokozinzo olungqongqo kunye nembono yoxanduva, ukusetyenziswa kanye ngumgaqo. Oku kubonakala kuyinkcitho, kwaye kunjalo. Yiyo loo nto kufuneka kugxininiswe ekuyileni ukuchithwa kunye nokubuyiselwa kwezinto eziphathekayo. Ibholithi ye-10.9S yintsimbi yekhabhoni okanye ialloy steel. Ekupheleni kobomi, i-100% inokuphinda isetyenziswe ngokuhlukana kwamagnetic kwimijelo yesinyithi esilahliweyo. Ixabiso kukugcina loo nto inyulu. Kulapho i-zinc-flake coatings ikhazimla kwakhona xa ithelekiswa ne-hot-dip galvanizing. Ingubo encinci, engeyiyo isinyithi ayingcolisi kakhulu intsimbi enyibilikayo, yenza inkqubo yokuhlaziya icoceke kwaye isebenze ngakumbi.

Sasebenza kwiprojekthi yokuphelisa ugunyaziso kumzi-mveliso omdala. Iibholiti ze-10.9S, nasemva kweminyaka engama-20, zichongiwe ngokulula, zasuswa (ngomzamo omkhulu, zinikezelwe), kwaye zathunyelwa ngqo kwi-scrap yard njengentsimbi yomgangatho ophezulu. Imiqadi yealuminiyam ababeyibambile nayo yahlulwa ngokucocekileyo yaza yahlaziywa. Uyilo, olusebenzisa ubungakanani obuqhelekileyo bebholiti kunye noqhagamshelo olufikelelekayo, luququzelele oku. Intlawulo yokuzinza yeza ekupheleni, kungekhona nje ngexesha lokusebenza.

Isiphelo: Imalunga neNkqubo, hayi iCandelo

Ke, ngaba iibholiti ze-10.9S zizinzileyo? Ngokwahlukileyo, hayi. Intsimbi yintsimbi. Kodwa njengesixhobo esibalulekileyo kwinkqubo yemizi-mveliso eyilwe ngobuchule nangobuchule, igalelo labo kuzinzo alinakuphikiswa. Kumalunga nokubachaza ngenxa yezizathu ezifanelekileyo-ukuvumela ukunciphisa izinto eziphathekayo, ukwandisa ubomi benkonzo ngokukhuselwa kwe-corrosion ephezulu, ukuququzelela ukusetyenziswa kwezinye izinto ezizinzileyo, kunye nokuqinisekisa ukubuyiswa kwakhona kokuphela kobomi.

Ukusilela endikubonileyo-amalungu akhululweyo, ukubola kwangaphambi kwexesha-phantse ahlala elandela umva ekuphatheni njengento yorhwebo. Usetyenziso lwabo oluzinzileyo lufuna ukuhlonelwa kwayo yonke iprothokholi: uyilo, ukukhangela kubenzi bomgangatho (ingaba ngumthengisi wasekhaya okanye umvelisi wesiseko esikhulu njengeHandan Zitai Fastener), ulungiselelo lomphezulu, ufakelo olulungelelanisiweyo, kunye nehardware eyiqabane elifanelekileyo. Litsheyini, kwaye ibholithi lelona khonkco libonakalayo.

Ekugqibeleni, eyona bholithi izinzileyo yileyo engasoze ifune ukutshintshwa, evumela ukuba ulwakhiwo lulonke lusebenze ngokufanelekileyo amashumi eminyaka, kwaye inokubuyiselwa ngokucocekileyo kwaye izalwe ngokutsha ekupheleni kwenkonzo yayo. I-bolt ye-10.9S, kunye nobukhulu bayo obuphezulu, ubunjineli obuchanekileyo, ibekwe ngokukodwa ukuhlangabezana nalo mngeni-kodwa kuphela ukuba thina, iinjineli, izichazi, kunye nabarhwebi, senze indima yethu ukuyidibanisa ngokuchanekileyo. Sisixhobo, kwaye impembelelo yayo yokusingqongileyo imiselwa sisandla esisiphetheyo.
