Ubwino wa kulongedza graphite pa ma valve a zida

Mu ntchito zamafakitale, kusankha zipangizo zopakira ma valavu a zida ndikofunikira kwambiri kuti zitsimikizire kuti zikugwira ntchito bwino komanso nthawi yayitali yogwirira ntchito. Pakati pa zosankha zosiyanasiyana zomwe zilipo, zodzaza ma graphite zimasiyana ndi zomwe zili ndi mawonekedwe ake apadera komanso zabwino zambiri. Nkhaniyi ikufotokoza za ubwino wa kuyika ma graphite makamaka pa ma valavu a zida, ndikugogomezera chifukwa chake ndi chisankho choyamba m'mafakitale ambiri.

Hikelok ikhoza kupereka zinthu zosiyanasiyanamavavu a zidakuti ndi kulongedza graphite, mongaMa Vavu a Mpira,Mapepala opindidwa,Ma Vavu a Singano,Valavu Yoyezera, Valavu Yotseka ndi Yotulutsa Magazindi zina zotero.

Kukana kutentha kwambiri

Chimodzi mwa zabwino kwambiri za graphite filler ndi kukana kwake kutentha kwambiri. Graphite imatha kupirira kutentha kwambiri, nthawi zina, kuyambira kutentha kwa cryogenic mpaka kupitirira 500°C (932°F). Izi zimapangitsa kuti ikhale yoyenera kwambiri pa ma valve a zida zomwe zimagwira ntchito m'malo otentha kwambiri monga mafuta ndi gasi, kukonza mankhwala ndi kupanga magetsi. Kutha kusunga umphumphu pansi pa mikhalidwe yotere kumatsimikizira kuti valavu imagwira ntchito bwino popanda chiopsezo cha kutuluka kapena kulephera.

Kugwirizana kwabwino kwambiri kwa mankhwala

Ma valve a zida nthawi zambiri amagwira ntchito zosiyanasiyana zamadzimadzi, kuphatikizapo mankhwala owononga ndi zinthu zowononga. Zodzaza ndi grafiti zimakhala ndi mphamvu yolimbana ndi mankhwala, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo omwe zodzaza zachikhalidwe zimatha kuwonongeka kapena kulephera. Kusagwira ntchito kwake kumalola kuti zipirire kukhudzidwa ndi ma acid, maziko ndi zosungunulira, kuonetsetsa kuti phukusili limakhalabe lolimba komanso likugwira ntchito pakapita nthawi. Kugwirizana kwa mankhwala kumeneku sikungowonjezera moyo wa phukusili, komanso kumachepetsa ndalama zosamalira zomwe zimagwirizanitsidwa ndi kusinthidwa pafupipafupi.

Kukangana kochepa ndi kuvala

Ubwino wina wa zodzaza graphite ndi mphamvu zawo zochepa zokangana. Zikagwiritsidwa ntchito mu ma valve a zida, kulongedza graphite kumachepetsa kuwonongeka kwa ma valve stems ndi zigawo zina, zomwe zimapangitsa kuti ntchito ikhale yosavuta komanso kuchepetsa kugwiritsa ntchito mphamvu. Izi ndizothandiza makamaka pakugwiritsa ntchito ma valve nthawi zambiri kapena kupsinjika kwakukulu. Kuchepetsa kukangana kumathandizanso kuchepetsa kutentha, zomwe zimapangitsa kuti makinawo azigwira ntchito bwino.

Katundu wodzipaka mafuta

Graphite ndi mafuta achilengedwe, zomwe zikutanthauza kuti imadzipangira mafuta okha ikagwiritsidwa ntchito ngati chodzaza. Izi zimathandiza kwambiri pa ma valve a zida chifukwa zimathandiza kuchepetsa kufunika kwa mafuta ena, omwe nthawi zina angasokoneze ntchito ya valavu kapena kuipitsa malo omwe akukonzedwa. Makhalidwe odzipangira mafuta a graphite amatsimikizira kuti valavu imagwira ntchito bwino ngakhale pakakhala zovuta.

Kusinthasintha ndi kusintha kwa zinthu

Zodzaza ndi graphite zimakhala zosiyanasiyana ndipo zimatha kusinthidwa kuti zigwirizane ndi zofunikira zinazake. Zitha kupangidwa m'njira zosiyanasiyana, kuphatikizapo mawonekedwe oluka, owumbidwa kapena otulutsidwa, kupereka mayankho opangidwa mwapadera a mitundu yosiyanasiyana ya ma valve a zida. Kusinthasintha kumeneku kumapangitsa kuti zodzaza ndi graphite zikhale zoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana, kuyambira mankhwala mpaka mankhwala a petrochemicals, kuonetsetsa kuti zitha kukwaniritsa zosowa zapadera za ntchito iliyonse.

Kugwiritsa Ntchito Mtengo Mwanzeru

Ngakhale mtengo woyamba wa zodzaza za graphite ukhoza kukhala wokwera kuposa zodzaza zina zachikhalidwe, zabwino zomwe zimakhalapo nthawi yayitali nthawi zambiri zimaposa ndalama zomwe zimayikidwa pasadakhale. Kulimba kwa zodzaza za graphite, zosowa zochepa zosamalira komanso moyo wautali wautumiki zimathandiza kuti ndalama zisungidwe bwino pakapita nthawi. Mwa kuchepetsa kuchuluka kwa zosintha ndikuchepetsa nthawi yogwira ntchito, makampani amatha kupeza njira yotsika mtengo kwambiri yama valve awo opangira zida.

Cmapeto

Mwachidule, ubwino wa kulongedza graphite pa mavavu a zida ndi wochuluka komanso wosangalatsa. Kukana kwake kutentha kwambiri, kugwiritsa ntchito mankhwala bwino, kupsinjika kochepa, kudzipaka mafuta okha, kusinthasintha komanso kugwiritsa ntchito bwino ndalama kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Pamene makampani akupitilizabe kusintha ndikufunika mayankho odalirika komanso ogwira ntchito bwino, kulongedza graphite mosakayikira kudzakhala chisankho choyamba kuti zitsimikizire kuti mavavu a zida amagwira ntchito bwino.
