Pankhani yoyezera molondola, zida zoyezera kuwala za shafts zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti magawo a shafts ndi olondola komanso olondola. Kukhazikika ndi kukana dzimbiri kwa maziko awo m'malo onyowa zimakhudza mwachindunji kulondola kwa zotsatira zoyezera komanso moyo wautumiki wa zidazo. Poyang'anizana ndi malo ovuta okhala ndi chinyezi chambiri monga malo ogwirira ntchito zamafakitale ndi madera a m'mphepete mwa nyanja, maziko a granite, okhala ndi zinthu zawo zapadera komanso zabwino zotsutsana ndi dzimbiri, akhala chisankho chabwino kwambiri cha zida zoyezera kuwala za shafts.
Mavuto a malo onyowa ndi maziko a zida zoyezera
Malo okhala ndi chinyezi ndi vuto lalikulu lomwe maziko a zida zoyezera za shaft optical akukumana nalo. Chinyezi chomwe chili mumlengalenga sichidzangodzaza pamwamba pa maziko kuti chipange filimu yamadzi, komanso chingalowe mkati mwa zinthuzo. Pa maziko achitsulo, monga maziko achitsulo chopangidwa ndi chitsulo kapena zitsulo, malo okhala ndi chinyezi angayambitse kukhuthala ndi dzimbiri mosavuta, zomwe zimapangitsa kuti pamwamba pa maziko paziwonongeke, zomwe zimakhudza kulondola kwa kukhazikitsa ndi kukhazikika kwa chida choyezera. Pakadali pano, dzimbiri lomwe limapangidwa ndi dzimbiri lingalowenso mu zigawo zolondola za chida choyezera, zomwe zimapangitsa kuti zigawozo ziwonongeke, zomwe zimakhudza kwambiri kulondola kwa kuyeza ndi magwiridwe antchito abwinobwino a zidazo. Kuphatikiza apo, kukula kwa kutentha ndi kuchepa komwe kumachitika chifukwa cha kusintha kwa chinyezi kungayambitse kusintha pang'ono kwa kukula kwa maziko, zomwe zimapangitsa kuti muyeso usinthe ndikupangitsa zolakwika zomwe sizinganyalanyazidwe.
Mphamvu yachilengedwe yoletsa dzimbiri ya granite
Granite, monga mwala wachilengedwe, ili ndi ubwino woteteza dzimbiri. Makristalo amchere amkati amakhala olimba kwambiri ndipo kapangidwe kake ndi kolimba komanso kofanana, zomwe zimapangitsa kuti madzi asalowe bwino. Mosiyana ndi zinthu zachitsulo, granite sichita zinthu za mankhwala ndi zinthu zodziwika bwino za acidic kapena alkaline. Ngakhale ikapezeka pamalo ozizira okhala ndi mpweya wowononga kapena zakumwa kwa nthawi yayitali, imatha kusunga zinthu zokhazikika za mankhwala ndipo sidzakumana ndi mavuto monga dzimbiri kapena dzimbiri.
Mu makampani opanga makina m'madera a m'mphepete mwa nyanja, chinyezi cha mpweya m'mafakitale chimakhala chokwera chaka chonse ndipo chimakhala ndi mchere winawake. Chida choyezera cha ma shaft okhala ndi maziko achitsulo chopangidwa ndi kuwala chidzawonetsa zinthu zoonekeratu zowononga dzimbiri m'miyezi yochepa chabe, ndipo cholakwika choyezera chidzapitirira kuwonjezeka. Chida choyezera chokhala ndi maziko a granite chakhala chosalala komanso chatsopano monga kale pambuyo pa zaka zingapo zogwiritsidwa ntchito, ndipo kulondola kwake kwa muyeso kwakhala kokhazikika nthawi zonse, kusonyeza bwino momwe granite imagwirira ntchito bwino polimbana ndi dzimbiri m'malo ozizira.
Ubwino wonse wa maziko a granite
Kuwonjezera pa kukana kwake dzimbiri bwino, maziko a granite alinso ndi zabwino zina zambiri, zomwe zimapereka chitetezo chokwanira kuti chipangizo choyezera cha shaft optical chigwire ntchito bwino pamalo ozizira. Kuchuluka kwa kutentha kwa granite ndi kochepa kwambiri, kokha 5-7 × 10⁻⁶/℃. Pakusintha kwa kutentha komwe kumachitika chifukwa cha kusintha kwa chinyezi, sichidutsa mu kusintha kwa mawonekedwe, zomwe zimapangitsa kuti nthawi yayitali ya muyeso ikhale yokhazikika. Pakadali pano, mawonekedwe abwino kwambiri a granite oletsa kugwedezeka amatha kuyamwa bwino kugwedezeka kwakunja. Ngakhale zidazo zitakumana ndi kugwedezeka pang'ono chifukwa cha mphamvu ya nthunzi ya madzi pamalo ozizira, kugwedezeka kumatha kuchepetsedwa mwachangu, kupewa kusokoneza kulondola kwa muyeso.
Kuphatikiza apo, pambuyo pokonza bwino kwambiri, maziko a granite amatha kukhala osalala kwambiri, kupereka chizindikiro chodalirika choyezera bwino kwambiri magawo a shaft. Khalidwe lake lolimba kwambiri (kulimba kwa Mohs kwa 6-7) limapangitsa kuti pamwamba pake pakhale kukana bwino kuvala. Ngakhale mutagwiritsa ntchito pafupipafupi pamalo ozizira, sizingawonongeke, zomwe zimapangitsa kuti chipangizo choyezera chikhale cholimba kwambiri.
Pankhani yoyezera kuwala kwa ma shaft okhala ndi zofunikira kwambiri, mavuto a dzimbiri ndi kukhazikika komwe kumachitika chifukwa cha chinyezi sanganyalanyazidwe. Maziko a granite, omwe ali ndi mphamvu zachilengedwe zotsutsana ndi dzimbiri, magwiridwe antchito okhazikika komanso zabwino zonse, akhala yankho labwino kwambiri pamavuto awa. Kusankha chida choyezera kuwala cha ma shaft okhala ndi maziko a granite kumatha kutsimikizira kuti ntchito ikuyenda bwino komanso yokhazikika pamalo onyowa, kutulutsa deta yolondola komanso yodalirika yoyezera, ndikuteteza chitukuko chapamwamba cha mafakitale monga kupanga makina ndi ndege.
