A106grb opanda zitsulo opanga chitoliro katundu
Chitoliro chachitsulo chili ndi dzenje ndipo kutalika kwake ndi kokulirapo kuposa m'mimba mwake kapena kuzungulira kwachitsulo. Malingana ndi mawonekedwe a gawoli, amagawidwa kukhala mipope yachitsulo yozungulira, yozungulira, yamakona anayi ndi yapadera; Malinga ndi nkhaniyo, lagawidwa mu mpweya structural zitsulo chitoliro, otsika aloyi structural zitsulo chitoliro, aloyi chitoliro zitsulo ndi gulu zitsulo chitoliro; Iwo anawagawa mipope zitsulo kufala mapaipi, zomangamanga zomangamanga, zipangizo matenthedwe, makampani petrochemical, makina kupanga, pobowola miyala, zida mkulu-anzanu, etc; Malinga ndi ndondomeko yopanga, imagawidwa mu chitoliro chosasunthika chachitsulo ndi chitoliro chowotcherera chachitsulo. Wopanda chitsulo chitoliro anawagawa otentha anagubuduza ndi ozizira anagubuduza (chojambula), ndi welded zitsulo chitoliro lagawidwa molunjika msoko welded zitsulo chitoliro ndi kozungulira msoko welded zitsulo chitoliro.
Chitoliro chachitsulo sichimagwiritsidwa ntchito potumiza zinthu zamadzimadzi ndi ufa, kusinthanitsa mphamvu zotentha, kupanga zida zamakina ndi zotengera, komanso chitsulo chachuma. Kugwiritsa ntchito chitoliro chachitsulo kupanga gululi yomanga, mzati ndi chithandizo chamakina kumatha kuchepetsa kulemera, kupulumutsa chitsulo ndi 20 ~ 40%, ndikuzindikira zomangamanga zamafakitale komanso zamakina. Kupanga Milatho Yamsewu Wamsewu wokhala ndi mipope yachitsulo sikungopulumutsa zitsulo komanso kuphweka kumanga, komanso kuchepetsa kwambiri malo otetezera ndikusunga ndalama zogulira ndi kukonza.
Mwa njira yopanga
Mapaipi achitsulo amatha kugawidwa m'magulu awiri molingana ndi njira zopangira: mapaipi achitsulo osasunthika ndi mapaipi achitsulo. Mipope yachitsulo yowotcherera imatchedwa mapaipi otsekemera mwachidule.
1. Chitoliro chopanda msoko amatha kugawidwa mu chitoliro chotentha chosasinthika, chitoliro chozizira, chitoliro chokhazikika chachitsulo, chitoliro chotentha chowonjezera, chitoliro chozizira chozungulira ndi chitoliro chotuluka molingana ndi njira yopanga.
Mitolo yazitsulo mapaipi
Chitoliro chachitsulo chosasunthika chimapangidwa ndi chitsulo chamtengo wapatali cha carbon kapena alloy steel, chomwe chingagawidwe muzitsulo zotentha komanso zozizira (zojambula).
2.Welded zitsulo chitoliro lagawidwa ng'anjo welded chitoliro, kuwotcherera magetsi (kukana kuwotcherera) chitoliro ndi basi arc welded chitoliro chifukwa cha njira kuwotcherera osiyana. Chifukwa cha mitundu yosiyanasiyana kuwotcherera, izo lagawidwa molunjika msoko welded chitoliro ndi kozungulira welded chitoliro. Chifukwa cha mawonekedwe ake omaliza, amagawidwa mu chitoliro chozungulira chozungulira komanso choboola pakati (mabwalo, athyathyathya, etc.) chitoliro chowotcherera.
Chitoliro chachitsulo chokokedwa chimapangidwa ndi mbale yachitsulo yokulungidwa yowotcherera ndi matako kapena msoko wozungulira. Kumbali ya kupanga njira, iwonso anawagawa zitsulo chitoliro otsika-anzanu kufala madzimadzi, kozungulira msoko welded zitsulo chitoliro, mwachindunji adagulung'undisa welded zitsulo chitoliro, welded zitsulo chitoliro, etc. Wopanda chitsulo chitoliro angagwiritsidwe ntchito mapaipi madzi ndi mpweya. m'mafakitale osiyanasiyana. mipope welded angagwiritsidwe ntchito mapaipi madzi, mapaipi mpweya, mapaipi Kutentha, mapaipi magetsi, etc.
Mwa zinthu
Chitoliro chachitsulo akhoza kugawidwa mu carbon chitoliro, aloyi chitoliro, zosapanga dzimbiri chitoliro, etc. malinga ndi chitoliro zakuthupi (ie zitsulo kalasi).
Mpweya chitoliro akhoza kugawidwa mu wamba mpweya zitsulo chitoliro ndi apamwamba mpweya structural chitoliro.
Chitoliro cha aloyi chikhoza kugawidwa mu: chitoliro chochepa cha alloy, chitoliro cha aloyi, chitoliro cha aloyi, chitoliro champhamvu kwambiri. Chitoliro chokhala ndi chitoliro, chitoliro cha kutentha ndi asidi chosapanga dzimbiri, chitoliro cholondola (monga kovar alloy) chitoliro ndi chitoliro cha superalloy, etc.
Welded zitsulo chitoliro, amatchedwanso welded chitoliro, ndi zitsulo chitoliro welded ndi mbale zitsulo kapena zitsulo Mzere pambuyo crimping. Welded zitsulo chitoliro ali ndi ubwino wa ndondomeko yosavuta kupanga, dzuwa mkulu kupanga, mitundu yambiri ndi specifications ndi ndalama zochepa zida, koma mphamvu zake ambiri ndi otsika kuposa chitoliro chosasokonezeka zitsulo. Kuyambira m'ma 1930, ndi chitukuko chofulumira cha kupanga kwapamwamba kwambiri kwa mizere yosalekeza komanso kupita patsogolo kwa ukadaulo wowotcherera ndi kuyendera, ukadaulo wa weld wakhala ukuwongoleredwa mosalekeza, mitundu ndi mafotokozedwe a mapaipi azitsulo akuchulukirachulukira, mipope yachitsulo yopanda msoko yakhala ikuwonjezeka. zasinthidwa m'magawo ambiri. Welded zitsulo mipope anawagawa molunjika welded chitoliro ndi kozungulira welded chitoliro monga mwa mawonekedwe a weld.
Longitudinal welded chitoliro ali ndi ubwino wa ndondomeko yosavuta kupanga, mkulu kupanga dzuwa, mtengo wotsika ndi chitukuko mofulumira. Mphamvu ya ozungulira welded chitoliro zambiri apamwamba kuposa mowongoka welded chitoliro. Iwo akhoza kupanga welded chitoliro ndi lalikulu chitoliro awiri ndi yopapatiza akusowekapo, ndi welded chitoliro ndi awiri chitoliro osiyana ndi akusowekapo wa m'lifupi chomwecho. Komabe, poyerekeza ndi chitoliro chowongoka chowongoka chokhala ndi kutalika komweko, kutalika kwa weld kumawonjezeka ndi 30 ~ 100%, ndipo liwiro lopanga ndilotsika. Chifukwa chake, kuwotcherera kwa msoko wowongoka kumagwiritsidwa ntchito kwambiri pamapaipi ang'onoang'ono okhala ndi m'mimba mwake, ndipo kuwotcherera kozungulira kumagwiritsidwa ntchito kwambiri pamapaipi akulu akulu akulu.
Welded zitsulo chitoliro kwa otsika kuthamanga madzimadzi kufala (GB / t3091-2008) amadziwikanso kuti wamba welded chitoliro, amene amadziwika kuti chitoliro chakuda. Ndi chitoliro chachitsulo chowotcherera chomwe chimagwiritsidwa ntchito potumiza madzi, gasi, mpweya, mafuta, kutenthetsa nthunzi ndi madzi ena otsika kwambiri ndi zina. Khoma makulidwe a zitsulo chitoliro kugwirizana anawagawa chitoliro wamba zitsulo ndi unakhuthala chitoliro; Kumapeto kwa nozzle kumagawidwa mu chitoliro chopanda ulusi (chitoliro chosalala) ndi chitoliro chachitsulo chachitsulo. The welded zitsulo chitoliro kufala otsika-anzanu madzimadzi kufala osati mwachindunji ntchito kufala madzimadzi, komanso chimagwiritsidwa ntchito ngati chitoliro choyambirira cha kanasonkhezereka welded zitsulo chitoliro kwa otsika-anzanu kufala madzimadzi.
1.kanasonkhezereka welded zitsulo chitoliro kwa otsika-anzanu madzimadzi kufala (GB / t3091-2008) amadziwikanso ngati kanasonkhezereka welded zitsulo chitoliro, amene amadziwika kuti chitoliro woyera. Ndi chitoliro chotenthetsera chotenthetsera (chowotcherera ng'anjo kapena kuwotcherera magetsi) chomwe chimagwiritsidwa ntchito potumiza madzi, gasi, mafuta amlengalenga, kutentha kwa nthunzi, kutenthetsa madzi ndi madzi ena otsika kwambiri kapena zinthu zina. Khoma makulidwe a zitsulo kugwirizana chitoliro lagawidwa mu wamba kanasonkhezereka zitsulo chitoliro ndi unakhuthala kanasonkhezereka zitsulo chitoliro; Kumapeto kwa nozzle kumagawika mu chitoliro chopanda ulusi chosakanizika chachitsulo ndi chitoliro chachitsulo chachitsulo. Mafotokozedwe a chitoliro chachitsulo amawonetsedwa m'mimba mwake mwadzina (mm), yomwe ndi pafupifupi mtengo wamkati mwake. Ndi chizolowezi kugwiritsa ntchito mainchesi, monga 1/2, 3/4, 1, 2, etc.
