10.9S mabawuti: zisathe mafakitale ntchito? 

Tiyeni tidutse muyeso wa malonda. Mukamva mabawuti a 10.9S ndi kukhazikika mu chiganizo chomwecho, zomwe zimachitika nthawi yomweyo zimakhala zokayikitsa. Nthawi zambiri amangokhala greenwashing, chabwino? Wopanga wina akumenya eco-label pa cholumikizira champhamvu kwambiri chifukwa ndizomwe zimachitika. Koma patatha zaka zambiri m’sitolo ndi m’mapulogalamu a m’munda, ndawonapo kukambirana kusinthasintha. Ndizochepa chabe za bolt yomwe imakhala yobiriwira komanso zambiri za gawo lake pothandizira machitidwe okhazikika a mafakitale. Funso lenileni siliri ngati bolt ya 10.9S ndi yokhazikika, koma momwe katundu wake weniweni - atatchulidwa molondola ndikugwiritsidwa ntchito - angathandizire kuti moyo ukhale wautali, wogwira ntchito, ndi kusunga zinthu muzomangamanga ndi makina. Ndiko kumene nuance, ndi ntchito yeniyeni, imayambira.

Msana Wosamvetsetseka

Choyamba, kufufuza zenizeni. Bawuti ya 10.9S si yamatsenga. 10.9 imatanthauza mphamvu yocheperako ya 1000 MPa ndi chiŵerengero cha zokolola za 0,9. S ikuwonetsa kuti ndi bawuti yolumikizirana ndi mikangano. Lingaliro lake lokhazikika limayamba ndi ntchito yake: kukakamiza mamembala olumikizana mwamphamvu kotero kuti katundu amasamutsidwa ndi kukangana, osati kukameta ubweya wa bawuti. Izi zikutanthauza kuti mutha kugwiritsa ntchito mabawuti ochepa poyerekeza ndi zolumikizira zamtundu. Zomangira zochepa zimatanthauza zinthu zochepa, kubowola pang'ono, komanso zomangira zopepuka, zogwiritsa ntchito bwino. Ndikukumbukira pulojekiti yobwezeretsanso pa gantry ya conveyor pomwe kusinthira ku cholumikizira chopangidwa bwino cha 10.9S kunachepetsa kuchuluka kwa bawuti ndi 30%. Ndiko kupulumutsa kwachindunji kwa zinthu, koma kokha ngati mapangidwe ndi machitidwe ali opanda cholakwika.

Vutoli, ndipo ndidadzionera ndekha izi, ndikuwatenga ngati mabawuti amphamvu kwambiri. Ngongole yokhazikika imagwa ngati simukwaniritsa mphamvu yolumikizira yomwe ikufunika. Izi zikutanthauza kuti ma wrenches owongolera, kukonzekera bwino pamwamba (kuyeretsa sikelo ya mphero, kugwiritsa ntchito moyenera. ntchito zokhazikika zamakampani), ndikutsatira mosamalitsa njira zomangitsa. Ndawonapo zolumikizira zikulephera kuyang'ana chifukwa ogwira nawo ntchito adagwiritsa ntchito wrench yokhazikika m'malo mwa chida chowongolera. Mabotiwo anali abwino, koma cholumikiziracho chidasokonekera kuyambira tsiku loyamba, zomwe zidapangitsa kukonza msanga, kuwononga, komanso zosiyana kwambiri ndi machitidwe okhazikika.

Apa ndi pamene kufufuza kumakhala kovuta. Sikuti ma bolt onse a 10.9S amapangidwa ofanana. Kugwirizana kwazitsulo ndi kulondola kwa dimensional sikungakambirane za mphamvu yolosera yolimba. Takhala ndi maulendo abwino ndi magulu ochokera kwa opanga apadera m'madera omwe ali ndi zachilengedwe zozama, monga dera lozungulira Handan ku Hebei. Pali ukadaulo waukadaulo pamenepo. Mwachitsanzo, kampani ya Handan Zitai Fastener Manufacturing Co., Ltd., yomwe imagwira ntchito kuchokera ku maziko opangirawo, nthawi zambiri imakhala ndi mapulojekiti omwe amatchulidwanso kuti azitha kufufuza komanso kusasinthasintha. Malo awo pafupi ndi misewu yayikulu yoyendera ngati Beijing-Guangzhou Railway sizongopindulitsa; ikuwonetsa kuphatikizika mkati mwa njira zoperekera mafakitale okhwima, zomwe, malinga ndi momwe moyo umakhalira, zitha kuchepetsa kutulutsa kwamayendedwe pamaoda ambiri.

Kutalika Kwambiri Kuposa Kusintha

Kukhazikika kwenikweni mumakampani nthawi zambiri kumatanthauza kupanga zinthu zokhalitsa. Kukana kwa dzimbiri kwa msonkhano wa bolt wa 10.9S ndi chinthu chodzipangira kapena chopumira. Bolt yokha, yomwe imakhala ndi chitsulo chapakati cha carbon alloy, imatha kuchita dzimbiri. Kotero, chophimbacho sichiri chowonjezera; ndizogwirizana ndi moyo wadongosolo. Kuchoka pamiyala yachikhalidwe ya cadmium (poizoni) kupita ku zokutira za zinc-flake (monga Geomet kapena Dacromet) ndikuwongolera kwachindunji kwachilengedwe komanso magwiridwe antchito. Zovala izi zimapereka kukana kwa dzimbiri bwino popanda zitsulo zolemera.

Tinayesa izi pazigawo zamagetsi zakunja. Mitundu iwiri yolumikizirana yofanana, imodzi yokhala ndi ma bawuti a 10.9S otentha otentha, ina yokhala ndi zinc flake kuchokera kwa ogulitsa ngati Zitai Fasteners. Zokhala ndi malata otentha zidawonetsa dzimbiri loyera komanso kukwawa kofiira pakatha miyezi 18 m'malo ogulitsa. Gulu la zinc-flake? Zinkawonekabe zaukhondo, popanda chizindikiro cha kugwedezeka kwa malo. Kusanthula kwamitengo ya moyo kunakomera chotsatiracho kwambiri-palibe chifukwa chosinthira msanga, palibe chiopsezo cholanda, komanso kukonza pang'ono. Icho ndi chogwirika ntchito yokhazikika yamakampani: Kufotokozera chomangira chotetezedwa choyenera kuti chiwonjezere nthawi yautumiki ndikupewa kuwononga.

Koma apa pali tsatanetsatane yemwe nthawi zambiri amaphonya: ochapira. Pamalumikizidwe amtundu wa 10.9S, muyenera kugwiritsa ntchito ma washer olimba (HRC 35-45 nthawi zambiri). Ntchito yawo ndikugawa mphamvu yotsekereza ndikuletsa mutu wa bawuti/nati kuti usalowe muzinthu zolumikizidwa, zomwe zingayambitse kutayika. Ngati mumagwiritsa ntchito chotsuka chofewa, cholumikizira chimamasuka pakapita nthawi. Ndinaitanidwa kuti ndifufuze zolephera za bolt zomwe zinali zolephera zochapira. Mgwirizanowo unamasuka, zomwe zinayambitsa kugwedezeka, kuvala, ndipo pamapeto pake, kuyitana kuti asinthe. Kugwiritsa ntchito zolondola, zowumitsidwa zigawo zoyanjana ndizochepa zomwe zimakhala ndi zotsatira zazikulu za kukhulupirika kwa nthawi yayitali ndi kukhazikika kwa msonkhano.

Kuthandizira Lightweighting ndi Mwachangu

Apa ndipamene bolt ya 10.9S imakhala yothandizira kupanga zokhazikika. Pazida zam'manja - lingalirani ma turbine nacelles amphepo, mafelemu a batri yagalimoto yamagetsi, kapena kupanga modula - kulemera kumalumikizidwa mwachindunji ndikugwiritsa ntchito mphamvu. Kuthamanga kwakukulu kwa ma bawuti a 10.9S kumalola mainjiniya kuti agwiritse ntchito zitsulo zamphamvu kwambiri, zowonda kwambiri kapenanso ma aloyi a aluminiyamu m'malo olumikizirana, chifukwa katunduyo amafalikira bwino chifukwa cha kukangana.

Chitsanzo chenicheni: pulojekiti yokhudzana ndi mayunitsi a data center. Kapangidwe kake kanafuna mafelemu opangidwa ndi aluminiyamu kuti achepetse kulemera panthawi yoyendetsa. Vutoli linali kupanga zolumikizira zolimba, zodalirika za aluminiyamu, zomwe zimatha kukwawa. Yankho lake linali kugwiritsa ntchito mabawuti a 10.9S okhala ndi mawaya akulu olimba m'mimba mwake komanso njira yomangirira yokhazikika pakuyika bwino. Izi zidachepetsa kupsinjika kwa aluminiyamu ndikusunga mphamvu yoletsa. Zinagwira ntchito. Zinalola kugwiritsa ntchito mphamvu zowonjezera mphamvu koma zowonongeka (zotayidwa) muzojambula zopepuka, ndi dongosolo la bawuti limatsimikizira moyo wake wautali. Bawutiyo idathandizira kusankha kwazinthu zokhazikika.

Komabe, izi zimakankhira bolt mpaka malire ake. Mukuchita ndi ma coefficients osiyanasiyana okulitsa kutentha pakati pa chitsulo cha bawuti ndi, tinene, aluminiyamu. M'madera otentha a cyclic, izi zingayambitse kusinthasintha kwa preload. Tinaphunzira izi movutirapo pa chitsanzo choyambirira cha dongosolo lolondolera dzuwa. Kutentha kwatsiku ndi tsiku kunapangitsa kukulirakulirana kokwanira kumasula pang'ono mfundo zina, zomwe zimapangitsa kuti mamvekedwe amveke bwino. Kukonzekera sikunali bawuti yamphamvu, koma mapangidwe ophatikizana okonzedwanso okhala ndi mabawuti ochulukirapo pakutsitsa pang'ono pang'ono kuti apange dongosolo lokhazikika. Linali phunziro la kaganizidwe ka dongosolo—boliti ndi gawo limodzi chabe la chilengedwe cha makina ocholowana.

The Reusability Funso ndi Mapeto a Moyo

Funso lodziwika: kodi mungagwiritsenso ntchito mabawuti a 10.9S? Yankho lovomerezeka, lokhazikika kuchokera pamakhodi ambiri a uinjiniya ndi ayi, makamaka pamalumikizidwe ovuta. Chodetsa nkhawa ndikuti kupunduka kwa pulasitiki pakumangirira koyambirira komanso kuwonongeka kwa ulusi panthawi ya disassembly kusokoneza magwiridwe antchito. M'malo mwake, pazinthu zosafunikira, zachiwiri, ndawonanso kugwiritsidwa ntchito mosamalitsa ndikuwunika mosamalitsa - kuyang'ana ngati ulusi ukulira, kukokera, komanso kugwiritsa ntchito ulusi woyezera.

Koma kuchokera pakukhazikika kokhazikika komanso udindo, kugwiritsa ntchito kamodzi ndiye lamulo. Izi zikuwoneka ngati zowononga, ndipo zili choncho. Ndicho chifukwa chake cholinga chiyenera kukhala pakupanga disassembly ndi kubwezeretsa zinthu. Bawuti ya 10.9S ndi chitsulo chopanda mpweya kapena aloyi. Pamapeto a moyo, ndi 100% recyclable kudzera maginito kupatukana mu zidutswa zitsulo mitsinje. Phindu lake ndi kusunga zinthuzo kukhala zoyera. Apa ndipamene zokutira za zinc-flake zimawalanso poyerekeza ndi galvanizing ya dip yotentha. Chophimba chocheperako, chosakhala chachitsulo sichiyipitsa kwambiri zitsulo zosungunuka, zomwe zimapangitsa kuti ntchito yobwezeretsanso ikhale yoyera komanso yogwira mtima.

Tinagwira ntchito yochotsa ntchito pafakitale yakale yokonza zinthu. Maboti a 10.9S, ngakhale pambuyo pa zaka 20, adadziwika mosavuta, kuchotsedwa (ndi kuyesayesa kwakukulu, kuperekedwa), ndipo anatumizidwa molunjika ku bwalo lazitsulo ngati chitsulo chapamwamba. Miyendo ya aluminiyamu yomwe ankagwira inasiyanitsidwa bwino ndi kukonzedwanso. Kapangidwe kake, komwe kamagwiritsa ntchito kukula kwa bawuti kokhazikika komanso zolumikizira zopezeka, zidathandizira izi. Phindu lokhazikika linafika pamapeto, osati panthawi ya ntchito.

Kutsiliza: Ndi Za Dongosolo, Osati Chigawo

Ndiye, ma bolt a 10.9S ndi okhazikika? Podzipatula, ayi. Chitsulo ndi chitsulo. Koma monga chothandizira chofunikira mkati mwadongosolo lamafakitale lopangidwa mwaluso komanso lopangidwa mwaluso, zomwe amathandizira pakukhazikika sizingatsutsidwe. Ndi za kuwatchula pazifukwa zoyenera-kuchepetsa kuchepetsa zinthu, kukulitsa moyo wautumiki kudzera m'chitetezo chapamwamba cha dzimbiri, kuthandizira kugwiritsa ntchito zida zina zokhazikika, ndikuwonetsetsa kuti moyo wawo watha.

Zolephera zomwe ndaziwona - mafupa omasuka, dzimbiri asanakwane - pafupifupi nthawi zonse amawatenga ngati chinthu chamtengo wapatali. Kugwiritsa ntchito kwawo kosasunthika kumafuna kulemekezedwa kwa protocol yonse: kapangidwe kake, kufunafuna kuchokera kwa opanga osamala kwambiri (akhale ogulitsa akumaloko kapena opanga zinthu zazikulu ngati Handan Zitai Fastener), kukonzekereratu, kuyika koyenera, ndi zida zofananira. Ndi unyolo, ndipo bawuti ndiye ulalo wowoneka bwino kwambiri.

Pamapeto pake, bawuti yokhazikika kwambiri ndiyomwe siyenera kusinthidwa, yomwe imalola kuti dongosolo lonselo lizigwira bwino ntchito kwazaka zambiri, ndipo limatha kubwezeretsedwanso bwino ndikubadwanso kumapeto kwa ntchito yake. Bawuti ya 10.9S, yokhala ndi mphamvu zambiri, yopangidwa mwaluso, ili ndi mwayi wapadera wothana ndi vutoli - koma pokhapokha ngati ife, akatswiri, akatswiri, ndi amalonda, titachita gawo lathu kuti tiphatikize bwino. Ndi chida, ndipo mphamvu zake zachilengedwe zimatsimikiziridwa ndi dzanja lomwe limachigwiritsa ntchito.
