Icyiciro cya 12.9 bolts: nziza kubwubatsi burambye? 

Urabona iki kibazo kigaragara cyane muri spes no kuganira. Igisubizo kigufi ntabwo yego yoroshye. Biragerageza gutekereza urwego rwo hejuru rugomba kunganya guhitamo kuramba, ariko uwo ni umutego rusange. Akenshi biganisha ku buhanga burenze, ibiciro bitari ngombwa, kandi birasekeje, ibisubizo bitarambye iyo urebye ubuzima bwuzuye. Reka dukureho ibyo.

Allure hamwe nuburemere bwa 12.9

Ntawahakana imikorere. A. Icyiciro cya 12.9 bolt itanga imbaraga zingana zingana na 1220 MPa. Mu murima, ibyo bisobanura imbaraga zidasanzwe zidasanzwe no kurwanya umunaniro. Kubintu bihuriweho hamwe no gutondekanya imitingito, imashini ziremereye zometse, cyangwa imiterere-yingufu zikomeye, akenshi ni amahitamo yihariye. Urayikoresha kuko gutsindwa ntabwo ari amahitamo. Ndibuka umushinga wa retrofit ku kigo cyinyanja aho twasimbuye 8.8 bolts na 12.9s kugirango duhuze umuyaga uremereye. Amahoro yo mu mutima yari agaragara.

Ariko dore icyambere: ayo mahoro yo mumutima azanwa nigiciro cyibikoresho ningufu. Kugera kuri izo mbaraga bikubiyemo ibintu bivanga nka chromium, molybdenum, na nikel, hamwe no kuzimya neza no kurakara. Ikirenge cya karubone cyo kubyara imwe 12.9 isanzwe irenze urwego rwo hasi. Noneho, niba porogaramu idasaba MPa 1220, mubyukuri urimo gutwika karubone kumutekano wumutekano utazigera ukoresha. Kuramba bitangirana no kugereranya iburyo.

Ubundi kubabara umutwe ni hydrogène embrittlement. Iyo imbaraga nyinshi, niko byoroshye ibyuma. Ibi twabyize inzira igoye kumushinga hakiri kare dukoresheje 12.9 bolts yatumijwe mumashanyarazi. Icyiciro cyananiwe mugihe cya torque-up, gucamo kumuzi. Iperereza ryerekanye ibibazo byo gutondeka hydrogène. Byari isomo rihenze mugutanga amasoko. Ntabwo 12.9s zose zaremewe kimwe, kandi kuramba kwabo gushingira kumugenzuzi utagira inenge kugirango wirinde kunanirwa hakiri kare no gusimburwa.

Kuramba ni Sisitemu, Ntabwo ari Ibigize

Aha niho ikiganiro kiba impamo. Ubwubatsi burambye burambye ntabwo ari ugukomera kuri (guhana) igice kibisi. Byerekeranye no kuramba kwa sisitemu, kuramba, no kurangiza ubuzima. Bolt ya 12.9 mumashanyarazi ihuza ibyuma bishobora gutera inzozi mbi ya galvanic iyo idakingiwe, biganisha ku kwangirika hakiri kare ingingo zose. Ibyo biraramba? No.

Ndatekereza kumushinga wububiko aho spec yahamagaye 12.9 kubihuza byose byibanze. Twasubije inyuma kuri purlin-kuri-rafter ihuza, yakoraga cyane cyane imitwaro yo gukata. Twaganiriye ku rwego rwo hejuru 10.9 hamwe na Dacromet ikomeye. Injeniyeri yubwubatsi yakoresheje imibare arabyemera. Igiciro cyazigamye cyerekejwe kumurongo mwiza. Imikorere irasa nyuma yimyaka 7, kandi muri rusange imikorere y ibahasha yinyubako-ikora neza-ni nziza. Iyo ntsinzi itunganijwe.

Noneho hariho deconstruction. Ihame nyamukuru ryinyubako irambye ni ugushushanya gusenya no kugarura ibikoresho. Birenze urugero 12.9 bolt, akenshi ihindurwamo aho itanga umusaruro, birashobora kuba inzozi zo gukuraho utangije abanyamuryango bahujwe. Irashobora guhindura ibiti byongera gukoreshwa. Tugomba gutekereza kuri torque, kugerwaho, hamwe nubushobozi bwo kongera gukoresha. Igishushanyo cyemerera gusimbuza bolt no gukiza abanyamuryango akenshi biruta imbaraga mbisi zikintu kimwe.

Urunigi rwo gutanga hamwe nukuri kwukuri

Ibi ntabwo ari theoretical gusa. Aho bolts yawe iva mubintu cyane kugirango umushinga urambye kwisi. Kohereza intera ndende yo gufunga ibintu biremereye, byuzuye byongera karubone nini. Aha niho hantu nka Akarere ka Yongnian muri Handan, Hebei, baza kwishusho. Nicyo cyicaro cyumusaruro wihuse mubushinwa. Amasoko aturuka ku ruganda rubifitiye ububasha aho, ku mishinga yo muri Aziya cyangwa ndetse n’inzira zoherezwa ku isi, zishobora kugabanya cyane ibyuka byoherezwa mu mahanga ugereranije n’amasoko ava ku yindi migabane.

Fata isosiyete nka Hamagara zitai yihuta ukora co., Ltd.. Bishingiye kuri uwo musaruro wimbere, bahagaze kugirango bakorere imishinga minini hamwe nibikoresho byaho hamwe nubuhanga bwo gukora. Aho biherereye hafi ya gari ya moshi nini n’imihanda (https://www.zitaifacens.com burambuye ibikoresho byabo) bisobanura gukora neza. Kuri rwiyemezamirimo, gukorana nuwabikoze afite igipimo kandi kigera ku bikoresho fatizo birashobora gusobanura uburyo bwiza bwo kugenzura ubuziranenge hamwe nigihe cyizewe cyo kuyobora - ibintu bibuza gutinda guta no gukora kurubuga. Gutanga ibicuruzwa cyangwa igice kimwe cyanze kwangwa ni kunanirwa kuramba ukurikije igihe, lisansi, nibikoresho byapfushije ubusa.

Ariko ni inkota y'amaharakubiri. Kwibanda ku musaruro bisobanura kandi ko, nkuwagaragaje cyangwa umuguzi, ugomba gukora umwete wawe. Isoko ni rinini kandi ireme riratandukanye. Guhitamo kuramba ni bolt kuva kubitanga nkibi bifite igenzura rikomeye, ibyemezo bikwiye (nka CE, ISO), hamwe no gukurikiranwa. Bihendutse, bitamenyekanye 12.9 bolt binanirwa ni antitique irambye. Byerekeranye no gushakisha ibintu muburyo bukwiye bwa geografiya.

Ikiburanwa: Iyo 12.9 aribwo Guhitamo Kuramba

Reka tubyumve neza, hano haribintu rwose aho 12.9 bolts aribwo buryo burambye. Byose bijyanye nuburemere bwimitwaro no gushushanya ubuzima. Tekereza ku kiraro cyahagaritswe na kaburimbo, cyangwa ihuriro murwego rwo hejuru rwo hejuru. Gukoresha urwego rwo hasi byasaba ibintu byinshi-binini bya diametre nini, bolts nyinshi, isahani nini ihuza. Kwiyongera kwicyuma cya tonnage, guhimba ibintu, hamwe nuburemere muburyo bwose byashobokaga kurenza byoroshye umusaruro mwinshi wa bike, imbaraga-zikomeye.

Nagize uruhare mu mushinga wa turbine. Imizigo ifite imbaraga yari umusazi. Twakoresheje diameter nini ya 12.9. Igishushanyo cyemereye guhagarika urufatiro ruciriritse, ruzigama metero kibe amagana ya beto. Carbone yashizwemo yabitswe muri beto yarenze kure karubone yiyongera mubikorwa bya bolt. Ibyo ni ibaruramari ryuzuye. Bolt hano yashoboje kugabanya ibikoresho ahandi, aribwo buryo bwibanze bwo gushushanya birambye.

Urufunguzo nisesengura ryubuhanga. Ntabwo ari imyitozo yo kuranga. Ukoresha imibare kumurongo wihariye: umunaniro ukabije, imitwaro ihindagurika, ibidukikije byangirika, ibintu bisabwa byumutekano, kandi yego, ibiciro bya karubone byubundi buryo. Rimwe na rimwe, imibare yerekana amanota kuri 12.9.

Kurenga Icyiciro: Ibibazo Byukuri Kubaza

Noneho, kuzenguruka inyuma, kubaza niba Icyiciro cya 12.9 aribyiza nintangiriro yo kwibeshya. Ibibazo byukuri nibi: Ni irihe sano ryihariye rikeneye gukora mubuzima bwimiterere? Turashobora kubigeraho hamwe nibikoresho bike cyangwa sisitemu yoroshye? Ni ikihe giciro cyose cyibidukikije, kuva gushonga kugeza gusenywa?

Mu myitozo, ibi bivuze guhangana n'ibiringiti. Bisobanura gukorana hakiri kare naba injeniyeri n'abubatsi. Bisobanura guha agaciro ababikora bashora imari muburyo bwiza kandi busukuye kurwego rwo hasi. Bishobora gusobanura guhitamo 10.9 byemewe na producer wizewe nka Zitai hejuru yizina 12.9 ryinkomoko idashidikanywaho.

Ubwubatsi burambye bwubakiye kubikorwa-byo kwizerwa no kuramba. Rimwe na rimwe, ibyo ni a Icyiciro cya 12.9 bolt. Akenshi, ntabwo. Umuvuduko mwiza niwo wemeza ko imiterere imara igihe kirekire nkuko byateganijwe, hamwe no gutabarwa kwinshi, kandi umusaruro nogukoresha ntibyatakaje umutungo ugerayo. Nibyo kubara nta cyiciro kimwe gishobora gusubiza, ariko kimwe buri mushinga ukeneye gukemura.
