Kutanthauzira kwazinthu ndi kapangidwe kake
Nangula ya mbale yowotcherera imakhala ndi ndodo ya ulusi, nthiti yolimba komanso nthiti yolimba. Padiyo imayikidwa ndi ma bolts powotcherera kuti apange chophatikizika cha "bolt + pad". Pad imawonjezera malo okhudzana ndi konkire, imabalalitsa katunduyo ndikuwongolera bata.
Zida zazikulu ndi mawonekedwe
Zofunika:
Bolt: Q235, Q355 kapena 42CrMo chitsulo champhamvu kwambiri;
Pad: Q235 zitsulo mbale, makulidwe 10-20mm, kukula anapangidwa malinga ndi katundu.
Mawonekedwe:
Kulemera kwakukulu: Padiyo imabalalitsa kupanikizika ndipo imatha kupirira katundu kuchokera ku matani angapo mpaka matani makumi;
Anti-seismic and shock-resistant: Chomangira chowotcherera chimachepetsa chiopsezo cha kumasuka ndipo ndi choyenera kumadera onjenjemera;
Zotsutsana ndi dzimbiri komanso zolimba: Zonsezo zimakhala zokongoletsedwa ndi malata kapena zopakidwa utoto, zoyenera m'malo ovuta monga mankhwala ndi zam'madzi.
Ntchito ndi zochitika zoyenera
Ntchito:
Konzani zida zolemera (monga ma reactors, ng'anjo zopangira zitsulo), zida zazikulu zachitsulo (milatho, nsanja zamphamvu);
Pewani kukameta ubweya wopingasa ndi torque kuti muwonetsetse kuti zida zikugwira ntchito kwanthawi yayitali.
Zochitika:
Ukatswiri wamagetsi (zida zapansi panthaka), makampani opanga mankhwala (ma tanki osungira, ma reactors), zomera zazitsulo (zida zogubuduza).
Kuyika ndi kukonza
Kuyika:
Phazi lazitsulo zowotcherera limayikidwa mu maziko a konkire, ndipo padyo imapangidwira ku mesh yachitsulo;
Zida zikayikidwa, zimalumikizidwa ndi pad ndi ma bolts, ndipo wrench ya torque imafunikira kuti iwonetsetse kuti idayikidwa kale.
Kusamalira: Nthawi zonse fufuzani kukhulupirika kwa weld kuti mupewe dzimbiri ndi kutaya mphamvu.
Gulani malingaliro
Sankhani kukula kwa pad molingana ndi kulemera ndi kugwedezeka pafupipafupi kwa zida (mwachitsanzo, pad 200x200mm imatha kunyamula matani oposa 5);
Njira yowotcherera iyenera kutsata muyezo wa GB / T 5185, ndipo ndodo yowotcherera iyenera kufanana ndi mtundu wachitsulo (mwachitsanzo, Q235 imagwiritsa ntchito ndodo yowotcherera E43).
Kufananiza ndi kusankha kalozera wa nangula zazikulu zitatu
| Mtundu | 7-mawonekedwe nangula | Nangula mbale yowotcherera | Ambulera chogwirira nangula |
| Ubwino waukulu | Kukhazikika, mtengo wotsika | Mkulu wonyamula katundu, kukaniza kugwedezeka | flexible embedding, economics |
| Ntchito katundu | 1-5 tani | 5-50 matani | 1-3 matani |
| Zochitika zenizeni | Magetsi apamsewu, zopangira zitsulo zopepuka | Milatho, zida zolemera | Nyumba zosakhalitsa, makina ang'onoang'ono |
| Njira yoyika | Kuphatikizira + mtedza kumangiriza | Embedding + wowotcherera pad | Kuphatikizira + mtedza kumangiriza |
| Mulingo wotsutsana ndi corrosion | Electrogalvanizing (zachilendo) | Kupaka galvanizing otentha + kupenta (kukana kwa dzimbiri) | Galvanizing (wamba) |
Malingaliro osankha:
Zofunikira pazachuma: Nangula zogwirira maambulera zimakondedwa, poganizira zonse za mtengo ndi ntchito;
Zofunikira zokhazikika: Nangula wowotcherera mbale ndiye kusankha koyamba kwa zida zolemetsa;
Zochitika zokhazikika: Nangula wokhala ndi mawonekedwe a 7 ndi oyenera pazosowa zambiri zokonzekera.
