Nkhani - Chitoliro cha Chitsulo Chopangidwa ndi Ductile: Chinthu Chachikulu Chomwe Chimathandiza Pakupanga Mapaipi Amakono

Chitoliro chachitsulo chosungunuka, imapangidwa ndi chitsulo chosungunuka ngati maziko. Asanathire, magnesium kapena rare earth magnesium ndi zinthu zina zosungunula zimawonjezeredwa ku chitsulo chosungunuka kuti zisungunule graphite, kenako chitolirocho chimapangidwa kudzera mu njira zingapo zovuta. Kupadera kwa chitsulo chosungunuka ndikuti graphite yambiri kapena yonse yosungunuka imakhala yozungulira, ndipo mawonekedwe a kapangidwe kameneka amawongolera kwambiri magwiridwe antchito a chinthucho. Pambuyo pothira, kapangidwe ka metallographic kaChubu Chachitsulo Chakudandi ferrite komanso pearlite pang'ono, ndipo mawonekedwe ake ndi abwino.

Mbiri ya chitukuko chaChitsulo chachitsulo chosungunukaIli ndi zinthu zatsopano komanso zatsopano. Kumapeto kwa zaka za m'ma 1980 ndi kumayambiriro kwa zaka za m'ma 1990, pamene ukadaulo wopanga mapaipi achitsulo opangidwa ndi centrifugal akunja komanso zikhalidwe zovuta zovomerezeka ndi patent unatsekedwa, fakitale ya 2672nd ya gulu lankhondo la anthu omasuka la China (lomwe linatsogolera Xinxing Casting Pipe) linayamba ntchito yofufuza ndi chitukuko molimba mtima. Mu 1993, chitoliro choyamba chachitsulo chopangidwa ndi centrifugal ku China chinatulutsidwa bwino, zomwe zikusonyeza kuti dziko langa lapita patsogolo kwambiri pankhaniyi, ndipo zinatenga zaka zisanu ndi zitatu zokha kuti limalize ntchito yomanga ya zaka 40 ya mayiko akumadzulo. Masiku ano, Xinxing Casting Pipe yakula kukhala kampani yayikulu komanso yamphamvu kwambiri padziko lonse lapansi yopanga mapaipi achitsulo opangidwa ndi centrifugal, ndipo yatenga nawo mbali popanga miyezo ya mapaipi opangidwa ndi centrifugal, ndikulimbikitsa chitukuko cha makampani opanga mapaipi achitsulo opangidwa ndi ductile.

Mapaipi achitsulo a Ductile Ali ndi Makhalidwe Osiyanasiyana Ogwira Ntchito

1. Mphamvu Yaikulu ndi Kulimba KwabwinoMapaipi achitsulo opangidwa ndi ductile ali ndi mphamvu zambiri, ndipo mphamvu zawo zimawonjezeka kwambiri poyerekeza ndi mapaipi wamba achitsulo. Chifukwa chakuti graphite imagawidwa mu mawonekedwe ozungulira, kugawanika kwa matrix kumachepa, zomwe zimapangitsa kuti paipiyo isasweke mosavuta ikakakamizidwa kwambiri komanso ikagundidwa. Nthawi yomweyo, ilinso ndi kulimba kwabwino, yokhala ndi kutalika kopitilira 10%, ndipo imatha kusintha kuti igwirizane ndi nthaka, kuyenda kwa nthaka ndi zina mwanjira inayake. Sizosavuta kuwonongeka ndi kusintha kwa zinthu, zomwe zimapangitsa kuti ntchito ya netiweki ya mapaipi ikhale yodalirika.

2. Kukana Kwambiri Kudzimbiri: Kudzera mu njira zosiyanasiyana zothanirana ndi dzimbiri, monga utoto wa phula, simenti, epoxy coal tar, epoxy ceramic lining, aluminate simenti, sulfate simenti ndi polyurethane, mapaipi achitsulo opangidwa ndi ductile amatha kukana dzimbiri kuchokera kuzinthu zosiyanasiyana. Kaya imagwiritsidwa ntchito kunyamula gasi, madzi apampopi, kapena kutulutsa zimbudzi, imatha kusunga magwiridwe antchito okhazikika m'malo osiyanasiyana ovuta, kukulitsa nthawi yogwira ntchito ya payipi, ndikuchepetsa ndalama zosamalira.
3. Kutseka Kwabwino: Pakamwa pa chitoliro pamakhala mawonekedwe osinthasintha, omwe amatha kusintha kuti azitha kusinthasintha ndi kusintha mkati mwa mtundu wina, kupanga zotsatira zabwino zotsekera pa gawo lolumikizira chitoliro, ndikuletsa kutulutsa kwamadzimadzi. Nthawi yomweyo, njira yopangira chitolirocho molondola kwambiri imatsimikizira kulondola kofanana kwa soketi, imapititsa patsogolo magwiridwe antchito otsekera, ndikuwonetsetsa kuti makina a payipi akugwira ntchito bwino.
4. Kukhazikitsa KosavutaPoyerekeza ndi mapaipi ena, kulemera kwa mapaipi achitsulo chosungunuka ndi kochepa, ndipo njira yoyikira ndi yosavuta. Mawonekedwe ake osinthasintha amathandiza ogwira ntchito yomanga kuti agwire ntchito yolumikizira, kuchepetsa nthawi yoyikira ndi mphamvu ya ogwira ntchito. Pamalo omanga, kuyikira mapaipi kumatha kumalizidwa mwachangu popanda zida zovuta komanso akatswiri aluso, zomwe zimafupikitsa kwambiri nthawi ya polojekitiyi ndikuwonjezera magwiridwe antchito omanga.
5. Kugwira Ntchito Kwabwino kwa Antifreeze: M'madera ozizira, mphamvu ya mapaipi yoletsa kuzizira ndi yofunika kwambiri. Mapaipi achitsulo okhala ndi ductile ali ndi mphamvu yoletsa kuzizira. Bola ngati si malo ovuta kwambiri, sipadzakhala ming'alu ndi kuphulika kwa kuzizira. Izi zimapangitsa kuti igwiritsidwe ntchito kwambiri popereka madzi, kutentha ndi njira zina zamapaipi m'madera ozizira akumpoto, kupereka ntchito zodalirika kwa okhalamo ndi mabizinesi.

Chitoliro chachitsulo chopangidwa ndi ductile

Chitoliro cha Madzi cha Ductile Ironakhala chitoliro chofunikira kwambiri komanso chofunikira kwambiri pakupanga zomangamanga zamakono chifukwa cha magwiridwe antchito awo abwino kwambiri. Kuyambira pakupereka madzi ndi ngalande za m'mizinda mpaka kufalitsa mpweya, kuyambira pakupanga mafakitale mpaka mapulojekiti osamalira madzi, mapaipi achitsulo chosungunuka amagwira ntchito yofunika kwambiri m'magawo osiyanasiyana ndipo apereka zopereka zofunika pakuwonetsetsa kuti moyo wa anthu ndikukula bwino. Ndi kupita patsogolo kosalekeza komanso kupanga zatsopano kwa ukadaulo, magwiridwe antchito a mapaipi achitsulo chosungunuka apitilizabe kukula, ndipo kuchuluka kwa ntchito kudzakulitsidwa. Apitilizabe kuwala pakupanga zomangamanga mtsogolo.
