Icyiciro cya 8.8 bolts: urufunguzo rwo kubaka birambye? 

Urumva ubwubatsi burambye, kandi ibitekerezo bisimbukira kumirasire y'izuba, ibisenge byatsi, cyangwa ibyuma bitunganijwe neza. Ni gake umuntu atekereza kuri bolt. Iri ni ikosa ryambere. Kwemeza ko kuramba ari ibintu byaka cyane, amatike manini. Mubyukuri, ubunyangamugayo-no kuramba-muburyo ubwo aribwo bwose akenshi bushingira ku tuntu duto, twirengagijwe. Kandi mwisi yisi ihuza imiterere, icyiciro cya 8.8 cyicaye muri uyu mwanya udasanzwe: birasanzwe rwose, nyamara uruhare rwarwo muburyo burambye burasobanuka nabi. Ntabwo ari imbaraga gusa; bijyanye n'imbaraga zikwiye, zikoreshwa neza, kugirango wirinde imyanda, gusana, no gutsindwa imburagihe. Reka dukureho ibyo.

8.8 Ubwoko: Birenze Umubare

Iyo dusobanuye 8.8, tuba tuvuze imbaraga zingana zingana na MPa 800 nimbaraga zitanga 640 MPa. Icyo ni igitabo. Ku butaka, bisobanura bolt ifite imbaraga zihagije kubwinshi mubice byinshi bidafite aho bihuriye nubucuruzi bwubucuruzi ninganda - tekereza gukora ibyuma, guteranya, gushingira imashini. Ariko dore nuance ifatika: ni ahantu heza hagati yubuhanga burenze urugero no kudasobanura. Gukoresha urwego rwo hejuru nka 10.9 aho 8.8 ihagije isesagura, haba mubiciro byibikoresho ndetse na karubone. Gukoresha 4.6 ni urusimbi kumutekano. 8.8 nakazi ko gukora, kandi kubona ibisabwa neza nintambwe yambere iganisha kumikorere.

Ndibuka umushinga wububiko hashize imyaka. Igishushanyo cyahamagaye 8.8 M20 ya bolts kumurongo wose wongeyeho. Bisa neza. Ariko icyiciro cyageze kurubuga-gikomoka ku kugabanura ibiciro-cyari gifite ibimenyetso bidahuye. Bimwe byari byoroshye. Twagize amakenga, dukora ibizamini bibiri bitari bike, kandi bibiri kuri icumi byananiwe guhura n'imbaraga z'umusaruro. Gutanga kwose kwaranze. Ukwo gutinda byatwaye icyumweru. Isomo ntabwo ryerekeye ibizamini gusa; byari bijyanye n'umurongo w'icyizere. Bolt kubaka irambye Umusanzu ni zeru niba binaniwe imburagihe, biganisha ku gusimburwa, gushimangira, cyangwa bibi.

Aha niho ibimenyetso bifatika. Ukeneye utanga ibicuruzwa byinjijwe mubidukikije byukuri, ntabwo ari inzu yubucuruzi gusa. Kurugero, uwabikoze nka Hamagara zitai yihuta ukora co., Ltd., ikorera muri Yongnian-Ubushinwa bunini bwihuta-ifite ibikorwa remezo. Kuba yegeranye na gari ya moshi nini n'imihanda (https://www.zitaifacens.com) ntabwo ari aho kugurisha gusa; isobanura imikorere ya logistique no kugabanya ibyuka byoherezwa kubicuruzwa byinshi. Kwibanda kubice bisanzwe bivuze ko babaho kandi bahumeka ibintu nka 8.8. Nibikorwa byabo byibanze.

Kuramba na Coating: Intambara yo Kwangirika

Imbaraga ntacyo zimaze niba bolt igenda. Kuramba, kuramba ntibishobora kuganirwaho. Bolt ya 8.8 mubisanzwe ni karubone cyangwa ibyuma bivangavanze, kubwibyo bivura hejuru nubuzima bwayo. Ashyushye cyane (HDG) irasanzwe, ariko ni igicucu kinini. Kuri 8.8 bolts, uburyo bwo gushyushya burashobora rimwe na rimwe gutera hydrogène kwinjiza, gutinda guturika. Ugomba guturuka kubakora bumva kandi bagenzura ubu buryo bwo guteka nyuma ya galvanizing. Nabonye bolts ifata mugihe cyo gukomera amezi nyuma yo kwishyiriraho, ikimenyetso cyambere cyiki kibazo.

Ubundi buryo bwo gutwikira nka sisitemu ya galvanizing cyangwa zinc flake sisitemu (urugero, Geomet) igenda ikurura. Zitanga imbaraga zo kurwanya ruswa zidafite ubushyuhe bwinshi. Ariko bongeraho ikiguzi. Ibiharuro birambye hano ni ubuzima bwuzuye: ese ibiciro byimbere byambere bikuraho ingaruka nigiciro cyo gusimburwa mumyaka 15? Mubidukikije cyangwa hejuru-yubushuhe bwibidukikije, rwose. Kububiko bwimbere, birashoboka HDG kuva isoko yizewe nibyiza. Numuhamagaro wurubanza ushingiye kumugaragaro, ntabwo ari ibintu bisanzwe.

Twigeze gukoresha icyiciro cyumukara (cyoroshye) 8.8 bolts kumirimo yigihe gito, twibwira ko izasenywa mumezi atandatu. Umushinga watinze, bahaguma imyaka ibiri mumiterere-igice. Mugihe twabakuyeho, byafashwe bikomeye. Igikorwa cyo gucana kugirango kibacike cyari akajagari - ingufu zapfushije ubusa, igihe cyatakaye, kandi ibimera byari ibisakuzo bidasubirwaho. Bolt ihendutse, itavuwe ni antithesis ya kubaka irambye.

Kugenzura Igenzura: Aho Igitekerezo gihurira n'ingaruka

Nibinini binini hagati yubushakashatsi nukuri. Bolt 8.8 igera ku mbaraga zayo zifata binyuze muri preload ikwiye, mubisanzwe 70-80% byimbaraga zayo. Igishushanyo kivuga ko torque igera kuri 450 Nm. Ariko kurubuga, mumvura, hamwe ningaruka zisubirwamo? Amahirwe masa. Kurenza urugero-kurambura Bolt, birashoboka gutera plastike no gutakaza imitwaro ya clamp. Kurenza-torquing biganisha kunyerera hamwe numunaniro.

Kwimuka ugana kubaka irambye imyitozo iri gusunika uburyo bwinshi bugenzurwa. Ibipimo byerekana impagarara zitaziguye (DTIs) cyangwa ibikoresho byo kugenzura imizigo biratangaje, ariko biracyagaragara ko ari premium kubice bikomeye, ntabwo kuri buri 8.8. Igice cyo hagati gifatika ni abakozi batojwe kandi bakomezwa cyane, ibikoresho byahinduwe. Byumvikane shingiro, ariko nikintu kimwe kinini cyingenzi kugirango ibyo 8.8 bolts bikore nkuko byateganijwe mubuzima bwubuzima. Ihuriro ryananiranye risobanura imyanda yibikoresho no gusana ingufu nyinshi.

Ndibuka retrofit aho twagombaga gusimbuza amagana ya 8.8 yafunguye muri sisitemu yo mumaso. Gushyira umwimerere yari yarakoresheje umugozi utabangamiwe kandi ukeka ko gukomera ari byiza. Iperereza ryasanze ibihindu byinshi byarambuye birenze umusaruro. Ntabwo twasimbuye gusa bolts; twagombaga kongera guhuza amakuru arambuye kugirango twemererwe neza no kugenzura. Imyanda y'abakozi n'ibikoresho yari myinshi.

Gusubiramo Umuzingo: Iherezo ryubuzima kuri Bolt

Ntabwo ari gake dushushanya gusenya, ariko tugomba. Mugihe cyanyuma yubuzima, ibyo 8.8 bolts birashobora gukurwaho byoroshye kandi bigakoreshwa neza? Niba zashyizwemo imbaraga, igipande cya zinc kigora ibyuma bitunganya ibyuma. Niba bashushanyije cyangwa bafite ibindi bitwikiriye, barashobora kumanurwa kugeza kumurongo wo hasi. Bolt irambye cyane, birasekeje, irashobora kuba imwe isanzwe ikoreshwa muburinzi bwuzuye, bwumutse, nkuko ibyuma bisubirwamo byoroshye.

Iki nikibazo cya sisitemu. Isosiyete nka Handan Zitai Fastener, nkumuproducer, iri murwego rwo kuzenguruka. Kuba biherereye mu nganda zishingiye ku nganda birashoboka ko bisobanura uburyo bwiza bwo gukusanya ibyuma bisakara hamwe n’imiyoboro ikoreshwa neza. Iyo ukomotse kumasoko akomeye yumusaruro, uba winjiye muburyo butaziguye mubukungu bwibintu byizunguruka, nubwo bidacuruzwa nkibyo.

Mu mushinga uherutse gusezererwa, twagerageje gukiza ibihingwa 8.8 bivuye mubyuma byubatswe kera. Byinshi byangiritse cyangwa byangiritse mugihe cyo gukuraho. Bake barokowe bagombaga gusukurwa neza, kugenzurwa, no kongera kugeragezwa - inzira ihenze kuruta kugura ibishya. Yagaragaje ko kuri bolts, umuzenguruko nyawo ushobora kubeshya cyane mugushushanya guhuza kugirango byoroshye gusimburwa na bolt aho kongera gukoreshwa, kwemeza ko abanyamuryango b’ibyuma bikomeza kubaho mugihe gito, ingufu-nyinshi-zitanga umusaruro.

Umwanzuro: Linchpin itagaragara

Noneho, ni Grade 8.8 bolt urufunguzo rwa kubaka irambye? Ntabwo ari wenyine. Ni urufunguzo rushoboka, ariko ruzanye na caveats. Urufunguzo ruri mu biganza byabigenewe, umuguzi, hamwe nuwashizeho. Bisaba guhitamo amanota akwiye kumurimo, biva mubakora babishoboye babigenzuye neza (nkibiri muri hub nka Yongnian), gukoresha uburyo bwiza bwo kurinda ruswa kubidukikije, kubishyiraho neza, no gutekereza inzira yanyuma yubuzima.

Ntabwo ari byiza. Byerekeranye na discipline muburyo burambuye. Iyo ubyumvise neza, ibyo 8.8 bidasuzuguritse bifata ibintu byose bucece mumyaka mirongo, birinda impanuka ya karubone yo kwiyubaka hakiri kare. Iyo ubonye nabi, bahinduka intege nke, muburyo bwikigereranyo. Kuramba mubwubatsi byubakiye kuri miriyoni ibyemezo bito, bikwiye. 8.8 bolt nikibazo cyiza cyo kugerageza niba twita kubintu bifite akamaro rwose.
