Mining Machine-Wuj Jaw Crusher Parts
Mafotokozedwe Akatundu
WUJ nsagwada mbale ndi masaya mbale amapangidwa kuchokera manganese apamwamba mu ndondomeko yodziwika ndi mosalekeza kuyang'aniridwa pa maziko athu ndi malo kupanga.Tili ndi ulamuliro wonse pa khalidwe pa sitepe iliyonse ya ndondomekoyi, kuyambira kusankha zipangizo mpaka kupanga komaliza.WUJ JAW PLATE YOPANGIDWA NDI MANGANESE WA UTHENGA WABWINO.
Chibwano mbale lagawidwa mu chokhazikika nsagwada mbale ndi zosuntha nsagwada mbale.Ndilo gawo lalikulu la nsagwada.Chibwano chikathamanga, chibwano chosuntha chimakakamira pansagwada yosuntha kuti igwedezeke pawiri, ndikupanga ngodya yokhala ndi nsagwada yokhazikika kuti ifinyire mwala.Choncho, ndi zosavuta kuonongeka chowonjezera mu nsagwada crusher (otchedwa: kuvala gawo).
Monga chigawo chokhala ndi nsagwada zapamwamba zovala, kusankha kwa mbale za nsagwada kumakhudzana ndi mtengo ndi phindu la ogwiritsa ntchito.
WUJ ikhoza kusankha zida za mbale ya nsagwada, monga momwe tawonetsera patebulo ili:
| Mtundu Wazinthu | Kufotokozera |
| Chitsulo chachikulu cha manganese | Chitsulo chokwera cha manganese ndi chinthu chachikhalidwe cha mbale ya nsagwada ya nsagwada, yomwe imakhala ndi mphamvu yolimbana ndi katundu.Komabe, chifukwa cha kapangidwe ka chopondapo, ngodya pakati pa mbale zosuntha ndi zokhazikika za nsagwada ndizokulirapo, zomwe ndizosavuta kuyambitsa kutsetsereka kwa abrasive.Pamwamba kuuma mbale nsagwada ndi otsika chifukwa chosakwanira mapindikidwe kuumitsa.Mbalame ya nsagwada imavala mofulumira chifukwa cha kudula kwaufupi kwa abrasive.Kuti apititse patsogolo moyo wautumiki wa mbale ya nsagwada, zida zosiyanasiyana za nsagwada zapangidwa, monga kuwonjezera Cr, Mo, W, Ti, V, Nb. ndi zinthu zina kusintha mkulu manganese zitsulo, ndi kuchita kubalalikana kulimbikitsa mankhwala pa mkulu manganese zitsulo, kuti patsogolo kuuma koyamba ndi mphamvu zokolola.Kugwiritsa ntchito bwino kwapezeka popanga. |
| Chitsulo cha manganese chapakati | Chitsulo chapakati cha manganese chinapangidwa koyamba ndi Climax Molybdenum Industry Company ndipo chinalembedwa mwalamulo mu patent ya US mu 1963. Njira yowumitsa ndi yakuti kukhazikika kwa austenite kumachepa pambuyo pa kuchepa kwa manganese.Ikakhudzidwa kapena kuvala, austenite imakonda kusinthika komwe kumapangitsa kuti martensite asinthe, zomwe zimakulitsa kukana kwake.Common zikuchokera (%) wa sing'anga manganese zitsulo: 0.7-1.2C, 6-9Mn, 0.5-0.8Si, 1-2Cr ndi kufufuza zinthu V, Ti, Nb, osowa lapansi, etc. moyo utumiki weniweni wa sing'anga manganese zitsulo mbale ya nsagwada imatha kuonjezedwa ndi 20% poyerekeza ndi chitsulo chokwera cha manganese, ndipo mtengo wake ndi wofanana ndi chitsulo chokwera cha manganese. |
| High chromium cast iron | Ngakhale chitsulo chokwera kwambiri cha chromium sichimamva bwino, chimakhala ndi kulimba kolimba, kotero kugwiritsa ntchito chitsulo chambiri cha chromium ngati nsagwada sizimapeza zotsatira zabwino.M'zaka zaposachedwa, chitsulo chachikulu cha chromium chimaponyedwa mkati kapena kumangirizidwa ku mbale yansagwada yachitsulo chapamwamba cha manganese kuti apange mbale ya nsagwada yophatikizana ndi kukana kuvala wachibale wa nthawi zopitilira 3, zomwe zimathandizira kwambiri moyo wautumiki wa mbale ya nsagwada.Iyi ndi njira yabwino yopititsira patsogolo moyo wautumiki wa mbale ya nsagwada, koma kupanga kwake kumakhala kovuta, kotero n'kovuta kupanga. |
| Chitsulo chapakati cha carbon low alloy cast | Chitsulo chapakati cha carbon low alloy cast ndi mtundu wazinthu zosamva zomwe zimagwiritsidwa ntchito kwambiri.Chifukwa cha kuuma kwake kwakukulu (≥ 45HRC) komanso kulimba koyenera (≥ 15J/cm ²), Imatha kukana kutopa chifukwa cha kudula zinthu komanso kutulutsa mobwerezabwereza, motero kuwonetsa kukana kwabwino.Pa nthawi yomweyo, sing'anga mpweya otsika aloyi kuponyedwa zitsulo angathenso kusintha kuuma kwake ndi kulimba mu osiyanasiyana lalikulu ndi kusintha zikuchokera ndi kutentha ndondomeko ya mankhwala kuti akwaniritse zofunikira za zinthu zosiyanasiyana ntchito.Kuyesa kwa opareshoni kukuwonetsa kuti moyo wautumiki wa mbale ya nsagwada yopangidwa ndi chitsulo chapakati cha carbon low alloy ndiutali kuwirikiza katatu kuposa wopangidwa ndi chitsulo chachikulu cha manganese. |
Kusankhidwa kwa zida za nsagwada ziyenera kukwaniritsa zofunikira za kuuma kwakukulu ndi kulimba, koma kulimba ndi kuuma kwa zipangizo nthawi zambiri zimatsutsana.Choncho, posankha zipangizo muzochita, tiyenera kumvetsa bwino mmene ntchito ndi bwino kusankha zipangizo.
Mapangidwe ndi kuuma kwa zinthu ndizinthu zomwe sizinganyalanyazidwe pakusankha koyenera.
Nthawi zambiri, kuuma kwa zinthu kumakhala kokwera, komwe kumafunikira kuuma kwazinthu zomwe zimavalidwa mosavuta.Choncho, pansi pa chikhalidwe chokwaniritsa zofunikira zolimba, zipangizo zokhala ndi zovuta kwambiri ziyenera kusankhidwa momwe zingathere.
Njira yovala ya ziwalo zovalidwa mosavuta iyeneranso kuganiziridwa posankha zinthu zoyenera.
Ngati kudula kuvala ndiye chinthu chachikulu, kuuma kumayenera kuganiziridwa poyamba posankha zipangizo;Ngati kuvala kwa pulasitiki kapena kutopa kumakhala kokulirapo, pulasitiki ndi kulimba ziyenera kuganiziridwa poyamba posankha zinthu.
Inde, posankha zipangizo, tiyeneranso kuganizira za kulingalira kwa njira zawo, zomwe n'zosavuta kulinganiza kupanga ndi kulamulira khalidwe.
