20 # madzimadzi opanda chitsulo chitoliro wopanga
Chitoliro chamadzimadzi ndi mtundu wa chitoliro chachitsulo chokhala ndi gawo lopanda kanthu ndipo palibe weld kuyambira pachiyambi mpaka kumapeto. Chitoliro chachitsulo chili ndi gawo lopanda kanthu, lomwe limagwiritsidwa ntchito kwambiri ngati chitoliro chotumizira madzimadzi, mafuta, gasi, gasi, madzi ndi zinthu zina zolimba. Poyerekeza ndi zitsulo zolimba monga zitsulo zozungulira, chitoliro chachitsulo chimakhala ndi kupindika komweko ndi mphamvu yozungulira komanso kulemera kwake. Ndi chuma gawo zitsulo. Amagwiritsidwa ntchito kwambiri popanga zida zamakina ndi zida zamakina, monga chitoliro chobowola mafuta, shaft yotumizira magalimoto, chimango cha njinga ndi scaffold yachitsulo yomwe imagwiritsidwa ntchito pomanga.
Chitoliro cha Fluid ndi chitoliro chomwe chimagwiritsidwa ntchito makamaka kutengera media ndi zinthu zamadzimadzi.
Kuphatikiza pa zinthu zamadzimadzi monga madzi, mafuta ndi yankho, zolumikizira zolimba monga simenti, tirigu ndi malasha opukutidwa zimathanso kuyenda pansi pazifukwa zina.
Mapaipi amadzimadzi amatha kupangidwa ndi zitsulo, zitsulo zopanda chitsulo monga mkuwa ndi titaniyamu, ngakhalenso zinthu zopanda zitsulo monga mapulasitiki.
Chitoliro chamadzimadzi chiyenera kukhala ndi gawo lopanda kanthu, koma likhoza kukhala lalikulu, katatu kapena mawonekedwe ena aliwonse. Zida zina ziyenera kugwiritsa ntchito chitoliro cha makona anayi chifukwa chochepa, koma ambiri amagwiritsabe ntchito chitoliro chozungulira. Chubu chozungulira chimakhala ndi chiŵerengero chaching'ono kwambiri cha circumference / dera m'magawo onse a geometric, ndiko kuti, gawo lalikulu lamkati likhoza kupezeka pansi pa chikhalidwe chogwiritsa ntchito zipangizo zofanana.
Chitoliro chachitsulo chimagwiritsidwa ntchito kwambiri pamayendedwe amadzimadzi masiku ano chifukwa cha mtengo wake wotsika komanso mphamvu zambiri. Malinga ndi ndondomeko yake yopanga, mapaipi achitsulo amagawidwa m'mapaipi opanda zitsulo ndi mapaipi otsekemera. Mipope yowotcherera imagawidwanso mu mipope yowongoka kwambiri yowongoka (RW), mipope yowotcherera yozungulira (SSAW), mipope yolumikizira arc (UOE), ndi zina zambiri. Ndi chitukuko ndi kupita patsogolo kwa sayansi ya zinthu, kupanga teknoloji ndi zida zamagulu, mapaipi otsekemera apangidwa kwambiri. Welded chitoliro ali ubwino wa bwino khoma makulidwe ofanana, mwatsatanetsatane mkulu, mowa wochepa mphamvu ndi mkulu kupanga dzuwa kuposa chitoliro opanda msoko. M'mbuyomu, pafupifupi 100% ya chitoliro chopanda msoko idagwiritsidwa ntchito popanga mafuta ndi gasi (API standard). Masiku ano, oposa 95% a iwo asinthidwa ndi chitoliro chowotcherera ku United States, Japan ndi mayiko otukuka ku Ulaya.
① Nthawi zambiri, kutentha kwa ntchito yamachubu otenthetsera kumakhala pansi pa 450 ℃, ndipo machubu apakhomo amapangidwa makamaka ndi No. 10 ndi No.
②Machubu a boiler othamanga nthawi zambiri amakhala ndi kutentha kwambiri komanso kupanikizika kwambiri. Machubu adzakhala oxidized ndi dzimbiri pansi pa zochita za mkulu kutentha chitoliro mpweya ndi nthunzi. Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zokhalitsa, anti-oxidation yapamwamba ndi ntchito ya dzimbiri komanso kukhazikika kwadongosolo.
