Njira Yopangira Mapaipi a SMLS Osasokoneza
Kusankha Kwazinthu Zopangira:Mpweya wapamwamba kwambiri wa carbon steel umasankhidwa ngati zopangira zamapaipi opanda mpweya wachitsulo. Mpweya wa carbon muzitsulo ndi chinthu chofunika kwambiri pozindikira kuti ndi zotani komanso zoyenera pa ntchito zosiyanasiyana.
Kutenthetsa ndi kuboola:Chopangiracho chimatenthedwa mpaka kutentha kwambiri ndipo kenako amaboola kuti apange chipolopolo chopanda kanthu. Izi ndizofunikira popanga mawonekedwe oyamba a chitoliro ndipo zimatheka kudzera njira monga kuboola mozungulira, kutulutsa, kapena njira zina zapadera.
Kugudubuza ndi Kukula:Chigoba chobzalidwa chimadutsa njira zogubuduza ndi kukula kuti muchepetse kukula kwake ndi makulidwe a khoma kukhala miyeso yofunikira. Izi zimatheka pogwiritsa ntchito mphero zingapo zogudubuza ndi mphero kuti zikwaniritse mawonekedwe ndi miyeso yomwe mukufuna.
Chithandizo cha kutentha:Chitoliro chachitsulo chosasunthika cha kaboni chimakhala ndi njira zochizira kutentha monga kuziziritsa, kukhazikika, kapena kuzimitsa ndi kutenthetsa kuti ziwongolere makina ake ndikuchotsa zovuta zilizonse zotsalira. Chithandizo cha kutentha chimathandizanso kukwaniritsa microstructure yomwe mukufuna komanso katundu wa carbon steel.
Kuyesa ndi Kuyang'anira:Panthawi yonse yopangira, chitoliro cha carbon chosasunthika chimadutsa njira zosiyanasiyana zoyesera zosawononga komanso zowonongeka kuti zitsimikizire kuti zikugwirizana ndi zofunikira zoyenera. Izi zitha kuphatikiza kuyezetsa kwa akupanga, kuyesa kwa hydrostatic, kuyezetsa kwapano kwa eddy, komanso kuyang'ana kowoneka.
Kumaliza ndi Kupaka:Chitoliro chopanda msoko chikakwaniritsa zofunikira, chimamaliza njira zomaliza monga kuwongola, kudula, ndi kumaliza kumaliza. Kuonjezera apo, chitolirocho chikhoza kuphimbidwa ndi zipangizo zotetezera monga vanishi, utoto, kapena galvanizing kuti zisawonongeke, makamaka ngati zitsulo za carbon.
Kuyanika Komaliza ndi Kuyika:Chitoliro chotsirizidwa chachitsulo chosasunthika chimayang'aniridwa komaliza kuti chitsimikizire kuti chikukwaniritsa miyezo yonse yabwino komanso zofuna za makasitomala. Kenako imapakidwa mosamala ndikukonzedwa kuti itumizidwe kwa kasitomala.
