Kunena zoona, nditamva koyamba mawu akuti akugwedezeka pawonetsero zaka zingapo zapitazo, zomwe ndinachita nthawi yomweyo zinali zokayikitsa. Mawu ena otsatsa malonda, ndinaganiza. Dziko la gasket lili ndi zonena zokhuza moyo wautali komanso kusangalala ndi zachilengedwe zomwe nthawi zambiri sizikhala ndi zovuta zenizeni, kukhudzidwa ndi mankhwala, kapena nyengo yakale. Aliyense amakamba za ma gaskets pofuna kukana dzimbiri, koma kumenya zokutira utoto pamwamba? Izi nthawi zonse zimamveka ngati chinyengo chodzikongoletsera, njira yolipiritsa zambiri pagawo lomwe lingalephereke chifukwa tchipisi tating'onoting'ono kapena kusokoneza chisindikizo. Lingaliro wamba wamakampani - lomwe ndidagawana - ndikuti mumapeza chisindikizo chogwira ntchito kapena chokongola. Lingaliro lakuti mtundu wosanjikiza wokhawokha ukhoza kuthandizira kugwira ntchito ndi kukhazikika kunkawoneka ngati kutambasula.

Lingaliro Lolakwika Lachikulu: Mtundu Monga Kumaliza Basi

Apa ndipamene zochitika zothandiza zimayambira. Cholakwika ndikuwona kupaka utoto ngati wosanjikiza, wokongoletsa. Pakuyika kwa zinki kokhazikika, mumapeza chitetezo cha dzimbiri, zedi. Koma mtundu, womwe umatheka chifukwa cha zokutira zosintha ma chromate (mabuluu, achikasu, akuda, ndi zina zotero), sikuti ndi wongozindikiritsa magawo kapena makina ofananira. Chosanjikiza chopyapyalacho cha chromate chimakulitsa kukana kwa dzimbiri kwa zinc. Ndi chosindikizira kwa wosanjikiza malata. Choncho, a mtundu-wokutidwa kanasonkhezereka gasket si malata + utoto. Ndi dongosolo lathunthu lamankhwala apamwamba. Mbali yokhazikika imayambira apa: ngati combo iyi ikulitsa moyo wautumiki kwambiri m'malo ovuta kwambiri (ganizirani nsanja zakunyanja zopopera mchere kapena mlengalenga wamafakitale), mukuchepetsa kubwereza, kutsika, ndi zinyalala zakuthupi pa moyo wa chinthucho.

Koma apa pali zochitika zenizeni, zomwe mumangophunzira pofotokoza izi pama projekiti kapena kuthana ndi zolephera. Sikuti mitundu yonse ya plating ndiyofanana. Makulidwe ndi mtundu wa zinc wosanjikiza ndi maziko. Ndawonapo ma gaskets pomwe mtunduwo udali wowoneka bwino koma gawo lapansi la zinc linali lopyapyala kwambiri, zomwe zidapangitsa kuti dzimbiri lofiira limatuluka pakapita nyengo. Cholephereka sichinali chinthu cha gasket chokha, koma chotchinga chotchinga cha dzimbiri. Lonjezo lokhazikika limaphwanyidwa ngati chinthucho sichikukwaniritsa zofunikira zake zokhazikika. Zimakukakamizani kuti muyang'ane kupyola pa pepala lapadera ndikufunsa za kayendetsedwe ka kayendetsedwe kake. Wopereka ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., yochokera ku China chachikulu cholumikizira ku Yongnian, Hebei, nthawi zambiri imakhala ndi mwayi wopanga zophatikiza. Kuwongolera magawo opangira malata ndi kuwomba m'nyumba, m'malo motumiza kunja, kungatanthauze kusasinthika - chinthu chofunikira koma nthawi zambiri chimanyalanyazidwa pamachitidwe enieni a moyo.

Ndiye pali chemistry ya chromate palokha. Makampani akuyenda, ngakhale pang'onopang'ono, kutali ndi chromium ya hexavalent (yodziwika bwino, yothandiza kwambiri koma yapoizoni komanso yowongolera golide) kupita ku ma chromates atatu. Mitundu yatsopanoyi imakhala yowopsa kwambiri. Wopanga akamayika ndalama m'mizere yaying'ono ya chromate, chimenecho ndi sitepe yowoneka bwino yopita ku njira yokhazikika yopangira, kuchepetsa kuopsa kwa chilengedwe ndi thanzi la ogwira ntchito. Chifukwa chake, zatsopano sizili nthawi zonse muzinthu zomwe mumagwira m'manja mwanu, koma mumachitidwe kumbuyo kwa fakitale. Mukawunika, ndikofunikira kufunsa kuti ndi mtundu wanji wa chromate womwe umagwiritsidwa ntchito. Yankho limakuuzani zambiri za komwe kuli kofunikira pakampani.

Case in Point: The Valve Bank Retrofit

Ndiroleni ndikupatseni chitsanzo cha konkire kuchokera ku malo oyeretsera madzi omwe tidakambiranako kwakanthawi. Anali ndi zovuta zobwerezabwereza ndi ma gaskets opangidwa ndi zinc pamagetsi akunja a valve. Kuwonongeka kumayambitsa kukomoka komanso kutayikira, zomwe zimapangitsa kuti madzi awonongeke komanso kupwetekedwa mutu kwa miyezi 18 iliyonse. Tinapempha kuti ayesedwe ndi gulu la mitundu-yokutidwa kanasonkhezereka gaskets pogwiritsa ntchito blue trivalent chromate kumaliza. Mtunduwu udafunsidwa ndi gulu lokonza kuti lizizindikirika mosavuta ndi zinki zakale zasiliva.

Zaka zitatu zapita, zochulukitsazo zikugwirabe ntchito popanda kulephera kumodzi kokhudzana ndi gasket. Mtengo unali mwina 15-20% wokwera pa unit poyamba. Koma mukaganizira za mtengo wantchito wa gulu la anthu awiri omwe akugwiritsa ntchito tsiku limodzi kuti alowe m'malo mwa banki yamafuta, kuphatikiza mtengo wanthawi yocheperako kapena kutayika kwamadzi, chuma chimasintha kwambiri. Kupambana kosasunthika kunali pawiri: kuchepetsa kwakukulu kwa kugwiritsidwa ntchito kwa magawo ena ochepera komanso njira zopangira / zoyendera, komanso kupewa kutulutsa koyipa komwe kungachitike kuchokera ku zisindikizo zolephera. Uwu ndi mtundu wokhazikika womwe umafunikira - kugwira ntchito moyenera komanso kuchepetsa zinyalala komwe kumayendetsedwa ndi gawo lokhalitsa.

Phunziro silinali loti utoto-wokutidwa ndi yankho nthawi zonse. Pantchito yotentha kwambiri kapena yamphamvu kwambiri, mutha kuyang'anabe zosapanga dzimbiri kapena PTFE. Koma pazambiri zamafakitale zomwe zimawononga pang'ono, kuphatikiza uku kumapitilira kulemera kwake. Zinasintha kawonedwe kanga kuchoka pakuwona ngati gimmick mpaka kuzizindikira ngati chida chovomerezeka chowonjezera nthawi yokonza.

Zowona Zopanga ndi Zogulitsa

Kulowera mozama, funso lokhazikika silimangokhudza zomwe zimagwiritsidwa ntchito. Ndizokhudza momwe zimapangidwira ndikusuntha. Apa ndipamene geography ndi logistics zimagwira ntchito. Kampani yomwe ili pamalo opangira zinthu zambiri, monga Handan Zitai ali ku Yongnian komwe amalumikizana mwachindunji ndi ma njanji akuluakulu ndi misewu (Beijing-Guangzhou Railway ndi National Highway 107 zili pamenepo), ili ndi mwayi wobisika. Kuyenda bwino kumatanthauza kutsika kwa mpweya wa carbon pa katundu aliyense pamene zipangizo zimalowa ndi kutha. Kwa ogula padziko lonse lapansi, kuphatikiza dongosolo la ma gaskets ndi zomangira zina kuchokera ku gwero limodzi, zolumikizidwa bwino zimatha kuchepetsa mtengo wachilengedwe wogula. Ndizinthu zadongosolo zomwe sizimatchulidwa kawirikawiri m'mabuku azinthu koma ndizofunikira pakuwerengera kwathunthu.

Pansi pafakitale, kukhudzidwa kwa chilengedwe kumatengera kuwononga zinyalala. Zinc plating ndi chromating zimapanga madzi oipa. Opanga otsogola m'magawo ngati Yongnian tsopano ali pansi pa malamulo okhwima a chilengedwe, kukakamiza kuti agwiritse ntchito ndalama zotsekera kapena njira zochiritsira zapamwamba. Mukapeza kuchokera kwa opanga odziwika bwino, mukuthandizira mosalunjika kupanga zowongolera, zoyeretsa. Ndi mtundu wa kukhazikika kwa chain chain. M'malo mwake - kugula njira yotsika mtengo kwambiri m'sitolo yosalamuliridwa - kutha kupulumutsa masenti pa chidutswa chilichonse koma kutulutsa mtengo wachilengedwe movutikira. Uku ndi kuyitanitsa kwa akatswiri komwe tiyenera kupanga nthawi zonse: mtengo wotsika kwambiri poyerekeza ndi mtengo wotsika kwambiri.

Pomwe Innovation Ikadali Yaifupi

Tiyeni tisatengeke, komabe. Kuchitcha kuti luso lokhazikika kumafuna chiyeneretso cholemera. Njirayi ikadali yogwiritsa ntchito mphamvu zambiri (mabafa otenthetsera plating) ndipo amagwiritsa ntchito mankhwala. Zatsopano zenizeni zitha kukhala zokutira zopanda poizoni, zopanda mphamvu zomwe zimafanana kapena kupitilira magwiridwe antchito a zinc + trivalent chromate. Sitinafikebe. Zovala zina zokhala ndi bio kapena zotsogola za polima zimawonetsa lonjezano mu ma lab koma alibe zaka makumi ambiri zodalirika zotsimikizika zomwe makampani amafuna kuti azisindikizira.

Wina wothandiza hiccup ndi galvanic dzimbiri. Kulumikizana a mtundu-wokutidwa kanasonkhezereka gasket ndi chitsulo chosagwira ntchito (monga chitsulo chosapanga dzimbiri) pamalo onyowa amatha kufulumizitsa dzimbiri za zinki. Muyenera kusamala za kuphatikizika kwa zinthu. Ndawona gasket yopakidwa bwino ikulephera mwachangu chifukwa idayikidwa pakati pa ma flanges awiri osapanga dzimbiri mu dzenje lonyowa nthawi zonse. Gasket adadzipereka yekha mwaulemu, koma izi siziri zotsatira zokhazikika. Zotengera? Palibe zakuthupi ndi njira yapadziko lonse lapansi. Kufotokoza molondola ndi theka la nkhondo.

Kutsiliza: Njira Yothandiza, Osati Panacea

Kotero, kubwerera ku funso loyamba. Kodi ma gaskets opaka utoto ndi njira yatsopano yokhazikika? Kuchokera pazowona zenizeni, nsapato-pa-pansi, ndinganene kuti zikuyimira chisinthiko cha pragmatic kuzinthu zosamalira zokhazikika. Iwo si chosintha wobiriwira chatekinoloje. Kuthandizira kwawo kosasunthika kumapezedwa kudzera pakukulitsa moyo wowonetsetsa, kusintha kwamakampani kupita ku ma chromates otetezeka, komanso magwiridwe antchito omwe amawathandiza akagwiritsidwa ntchito moyenera.

Chofunikira ndikuziwona ngati dongosolo: maziko abwino a zinc, wosanjikiza wamakono wa chromate, ndi zowongolera zolimba zopanga. Othandizira omwe amamvetsetsa izi, monga omwe ali ndi zida zophatikizika m'malo opangira zinthu, ndi omwe amakwaniritsa lonjezo. Ndi chida. Ndipo monga chida chilichonse, mtengo wake - ndi kukhazikika kwake - zimatsimikiziridwa ndi chidziwitso ndi cholinga cha munthu amene akuchigwiritsa ntchito. Musanyalanyaze hype, yang'anani zomwe zagwiritsidwa ntchito, ndipo zitha kukhala gawo laling'ono koma lofunika kwambiri pomanga nyumba zamafakitale zolimba, zosawonongeka. Ndilo luso lenileni: kusintha momwe timaganizira za gawo lodzichepetsa pa chithunzi chachikulu.
