Ubuchwephesha bokungakhululeki koomatshini abazinzileyo? 

Uva i-anti-ukukhululwa kwaye ngoko nangoko ucinge i-locknuts okanye i-threadlocker, akunjalo? Lowo ngumgibe oqhelekileyo. Incoko yokwenene ayikho malunga nokumisa ibholithi ekujikeni; imalunga nokulawula ukubola komthwalo we-clamp kwindawo eshukumayo, i-thermal-cycling bume ngaphezu kweminyaka eyi-15 yobomi bomatshini. Ukuzinza apha akusiyo i-buzzword-imalunga nokuthintela ukungaphumeleli kwangaphambi kwexesha, ukuphepha amandla kunye nenkunkuma yezinto eziphathekayo ngokuphindaphindiweyo okanye ukutshintshwa, kwaye ngokunyanisekileyo, ukumisa i-cascade ye-downtime. Uninzi lweengxoxo ziyayiphosa into yokuba i-fastener yinxenye nje yenkqubo edibeneyo. Ukuba uyilo okanye ukufakwa kuneziphene, kwaneyona teknoloji ibalaseleyo ayiyi kuyigcina.

Ingxaki engundoqo: Ayisiyongxaki, imalunga nokungaguquguquki

Kwasebutsheni bexesha lam lokugcinwa koomatshini abanzima, sasiye sileqe ukukhulula okubangelwa kukungcangcazela ngokuqinisa nje iibholithi. Impazamo yakudala. I-Over-torquing yolula ibholiti, enokuthi ibangele uxinzelelo lwe-corrosion cracking okanye ngokulula ukuyiphanga ukuqina kwayo-ubuchule bayo bokusebenza njengentwasahlobo kunye nokugcina amandla obambe. Injongo yinto engaguqukiyo, ethembekileyo yomthwalo obambekayo olwela ukuzikhulula. Ndikhumbula isakhelo se-conveyor drive esasizishukumisa ngokwaso qho kwiinyanga ezintandathu. Sizame i-serrated flange nuts, esebenze… kangangeenyanga ezisibhozo. Umba wawuyipeyintiwe, iindawo zokukhwelana ezingalinganiyo zidala usasazo loxinzelelo olungalinganiyo. I-nut ayizange isilele; uyilo oludibeneyo lwenzile.

Kulapho umsebenzi wokwenyani uqala khona. Kufuneka ujonge yonke into edibeneyo: iklasi yepropathi ye-fastener, i-flange flatness, ukuqina kwezinto ezidibeneyo. Iwasha eqinileyo phantsi kwentongomane eqhelekileyo kwizindlu ezithambileyo zealuminiyam icela nje ukubethelela kunye nokulahleka komthwalo. Sifunde ukucacisa imizobo edibeneyo, ukubala i-curve-deformation curve. Ivakala njengemfundo, kodwa ngumahluko phakathi kwejoyinti elisindayo nelithi libe yintloko ebuhlungu.

Kulapho abavelisi abafumana indlela yenkqubo bagqama khona. Bendikhangela ababoneleli abanokuthetha ngaphezu kwemigangatho yeDIN kuphela, kwaye ndadibana I-Sunnian Zitai Festener Fishaner Comment Com.. Indawo yabo eYongnian, eso siseko sikhulu semveliso, ithetha ukuba bayibonile yonke loo nto. Eyona nto yayiluncedo yayingeyokhathalogu yabo kuphela, kodwa amanqaku abo obunjineli kwiimeko zesicelo. Yinto enye ukuthengisa a ekhoyo torque nut; yenye ukucebisa xa usebenzisa inayiloni ufakelo ngokuchasene nentsimbi-alloy intambo deformed ngokusekwe kuluhlu lobushushu kunye neemfuno reusability. Elo galelo lisebenzisekayo, elisekelwe kumava liyigolide.

Ngaphaya Kwemichiza: Ukutshixwa koomatshini kwindawo eNcincisayo

Ii-threadlockers zinendawo yazo-umsebenzi ophantsi ukuya ophakathi, iindawo ezivaliweyo. Kodwa kwi-excavator yemigodi okanye kwi-flange ye-wind turbine tower flange? Libala. I-UV, ubushushu obugqithisileyo, i-fuel, kunye nokungcangcazela okukodwa kuya kwaphula i-adhesive. Ukuzinza, ufuna isisombululo esinomatshini, esinokuphinda sisebenziseke. Siye savavanya iinketho ezahlukeneyo kwiiseti zejeneretha yedizili.

Amandongomane okutshixa okuphezulu anecandelo lomsonto okhubazekileyo asebenze kakuhle kumanqaku afikelelekayo kodwa yayiyintlungu kwiindawo ezixineneyo. Sineziphumo ezingcono zexesha elide kunye Iinkqubo zokuhlamba ezitshixayo. Umgaqo ulula: iikhamera ze-angled kwi-washers zigrumba, zenza i-counter-force ngokumelene nokujikeleza. Isitshixo, nangona kunjalo, kukufako okufanelekileyo-zisebenza kuphela kwindawo ekujoliswe kuyo. Ndibone abasebenzi bebabetha ngasemva, bebenza bangabi namsebenzi. Uqeqesho luyinxalenye yetekhnoloji.

Emva koko kukho umpu omkhulu: ibholithi yokulawula uxinzelelo (i-TC bolt) iinkqubo ezineewasha eziqinileyo. Ezi zilungile kuqhagamshelo lweflange enkulu, njengentsimbi yesakhiwo okanye iihabhu zeinjini yomoya. Usebenzisa isikrufu sokucheba esisikrazula isiphelo se-spline xa uxinezeleka oluchanekileyo. Ikunika ubungqina obubonakalayo, bokuhamba/ukungahambeli bofakelo oluchanekileyo. I-engile yozinzo icacile: ijoyinti elayishwe ngokuchanekileyo ibona intshukumo encinci, inciphisa kakhulu ukudinwa kunye nokudinwa. Yintoni embi? Izixhobo ezikhethekileyo kunye nexabiso leyunithi ephezulu. Kuya kufuneka uyithethelele ngeendleko zomjikelo wobomi, hayi inkcitho yangaphambili.

Inqaku eliKhawulezileyo kwiMiba eSolwa ngokuMahala

Ngaba wakha wanentongomane ejikeleza ngokukhululekileyo kodwa engazange iqinise? Ngokuqhelekileyo ithathwa njengentambo embi. Ngamanye amaxesha kuba njalo. Kodwa rhoqo, yi-bolt pitch pitch deformation ukusuka kwi-torquing yangaphambili, okanye i-debris epakishwe kwindawo yokutshixa i-nut. Yinkcukacha encinci, ephazamisayo emisa umgca wendibano yonke. Ulungiso aluyonto nje entsha; ihlola umsonto wendoda ngegeyiji kunye nokucoca imiphezulu yokukhwelana. Kucacile, kodwa ngokungahoywanga ngokungxama ukwenza izinto ziqhube.

Izinto eziphathekayo kunye nomdaniso wokugquma

Uzinzo lukwathetha ukulwa nomhlwa, otya izinto kunye nokwandisa ukukhuhlana, ukuguqula ubudlelwane be-torque-tension. Ilungu legalvanically corrod libamba okanye liphulukane nomthwalo wokubamba. Thina emgangathweni kwi eshushu-diphu yagalvanized okanye i-dacromet-coated izibophelelo zangaphandle, izicelo zokufuma okuphezulu. Kodwa nantsi into yokubamba: iingubo zongeza ubukhulu. Ukuba awuyiphenduli loo nto kwi-torque specs zakho, uyaqina. I-15-micron i-zinc flake coating inokutshintsha kakhulu i-coefficient ye-friction. Sifunde ukubuza ababoneleli ngedatha yetorque-tension kwiimveliso zabo ezigqunyiweyo, hayi nje izinto ezisisiseko. Abanye, njengoZitai, babonelela ngezi tshathi ngokulula, nto leyo ebonisa ukuba bayasiqonda isicelo, hayi nje ukwenziwa kwezinto.

Inketho yezinto eziphathekayo yenye i-lever. Ukuhamba ukusuka kwinqanaba le-8.8 ukuya kwi-10.9 okanye kwi-12.9 ivumela i-bolt encinci ye-diameter kumthwalo ofanayo, ukugcina ubunzima kunye nezinto eziphathekayo. Kodwa udidi oluphezulu luthetha ukuchaphazeleka okuphezulu kwi-hydrogen embrittlement ukuba ayilungiswanga ngokuchanekileyo. Uthengisa umngcipheko omnye komnye. Sasinebhetshi yeebholiti zodidi oluphezulu zisilele ngokuyingozi kwi-press fit-yajika inkqubo yokucwenga yazisa i-hydrogen, kwaye ayizange ibhakwe ngokufanelekileyo ngenxa yokukhupha. Umthengisi utyhola itorque yethu yofakelo. Yayisisifundo esonakeleyo ekuvavanyeni lonke inkqubo yolawulo lwenkqubo yobonelelo.

Ukufakela: Apho obona buchwephesha buya kuFa

Lo ngumwonyo omkhulu phakathi kwethiyori kunye nokusebenza. Ungakhankanya iwasha egqibeleleyo ye-Nord-Lock okanye isiqhoboshi se-polymer ephucukileyo. Ukuba umfana onempembelelo ye-wrench akayazi inkqubo, ayinaxabiso. Izitshixo zetorque ezilinganisiweyo ziyimfuneko, kodwa zijongwa kangaphi? Siphumeze inkqubo apho amalungu abalulekileyo (cinga ukunyuswa kwebhokisi yegiya, amakhonkco olwakhiwo) afuna i-torque log esayiniweyo kunye ne-ID yesixhobo. Ivakale iburhulumente, kodwa yasika iintsilelo ezinxulumeneyo mhlawumbi ngama-70%.

Ulandelelwano lubalulekile kakhulu, ngakumbi kwiiflange ezinebholithi ezininzi. Ipateni yeklastiki yeenkwenkwezi ifundiswa ngesizathu-iqinisekisa nokuba i-gasket okanye ukunyanzeliswa komphezulu. Ndikhe ndabukela oomatshini abanamava bengayihoyi le nto kwi-hydraulic manifold, ekhokelela ekuvuzeni okuzingileyo ababeleqa iiveki ngokuqinisa ibholithi enye ngokuphindaphindiweyo. Bajija iflange. Ngamanye amaxesha obona buchwephesha bokuchasana buzinzile liphepha: umyalelo ocacileyo, onemifanekiso yomsebenzi.

Kukho kwakhona into yokuziva komntu. Ifitter enamava ngamanye amaxesha inokubona umsonto onqamlezileyo okanye ibholithi enikezelayo ngokutshintsha kokumelana ngexesha lokuqina, into ethile isisithulu setorque esisithulu sivele siqhume. Loo ngxelo ibambekayo ngumaleko ongenakubuyiselwa wolawulo lomgangatho. Siqale ukubhanqa irente emitsha kunye nala magqala ngokukodwa kwimisebenzi ebalulekileyo yokufaka iibholiti, ukubamba olo lwazi lucwangcisiweyo.

Ukujonga Phambili: I-Smart Joint?

Kukho intetho malunga neziqhoboshi ezihlakaniphile ezinezinzwa ezibethelelweyo ukujonga ukulayisha kwangaphambili. Ndiyathandabuza ukusetyenziswa ngokubanzi. Iindleko, ukuntsonkotha, kunye nokuqina kwiindawo ezirhabaxa zemizi-mveliso yimiqobo emikhulu. Okwangoku, eyona ndlela isebenzayo yobuchule kukusebenzisa i-ultrasonic bolt yomlinganiselo wobude obubalulekileyo, ufakelo olunye olufana neziseko ezinkulu zeiturbine. Ikunika umlinganiselo womthwalo othe ngqo, udlula zonke iinguqu zokukhuhlana. Iyabiza kwaye iyacotha, kodwa kwijoyinti awusoze ufune ukusilela, yeyona tshekhi yokugqibela.

Umda wokwenyani, ngokombono wam, kuyilo lokuqhaqha kunye nokugcinwa. Oomatshini abazinzileyo kufuneka banikwe inkonzo. Itekhnoloji echasene nokukhulula ebamba iqinile emva kweminyaka emihlanu (ndijonge kuwe, ezinye iintambo zemichiza) zichasene nokuzinza. Eyona nto ifanelekileyo lidibaniso elihlala libekwe ngexesha lokusebenza kodwa linokuchithwa ngezixhobo eziqhelekileyo ngexesha lokulungisa. Yiyo loo nto ndingqiyama kumatshini, izinto eziphinda zitshixelwe. Basenokufuna ukutshintshwa emva kwemijikelo embalwa, kodwa oko kungcono kunokusika okanye ukugrumba ibholithi kunye nokonakalisa imathiriyeli yomzali.

Ekugqibeleni, ngumdlalo weenkqubo. Awukwazi nje ukubethelela ukuzinza. Iqala ngokudibeneyo eyilwe kakuhle, ikhetha itekhnoloji efanelekileyo, ehlala ixesha elide yokutshixa kokusingqongileyo, iphumeza ngokuchanekileyo, kunye nezicwangciso zomjikelo wobomi bonke. Iinkampani ezibonelela ngamalungu omzimba kwaye Ubulumko besicelo, njengeqela kwi I-Zitai isantya ngaphandle kweso siseko semveliso ye-Handan enkulu, babe ngamaqabane, kungekhona nje abathengisi. Kuba eyona fastener ezinzileyo yileyo uyifake ngokuchanekileyo, kube kanye, kwaye ulibale malunga nobomi bomatshini.
