Ukuqonda amanqanaba eetsheyini kubalulekile ekukhetheni itsheyini efanelekileyo yemisebenzi yezoshishino, yokuphakamisa, okanye yokhuseleko. Njengoko kukho iintlobo ezininzi ezahlukeneyo zeetsheyini ezikwimarike, sazi njani ukuba sisebenzisa amanqanaba afanelekileyo etsheyini kwiiprojekthi zethu? Inyathelo lokuqala kukuqhelana namanqanaba eetsheyini, ukugqitywa kweetsheyini kunye noko zikuthethayo.
Zithini iiChain Grades?
Iiklasi zeetyathanga ziyindlela yokwahlulahlula iityathanga zentsimbi ye-alloy ngokusekelwe kumandla azo okutsalwa kunye nomda womthwalo wokusebenza (WLL). Okukhona inqanaba liphezulu, kokukhona ityathanga liqina kwaye linzima.
| Ibanga | Izinto eziphathekayo | Amandla okuThamba (psi) | Ukusetyenziswa Okuqhelekileyo |
| Ibanga lama-30 | Ikhoyili yoBungqina (ikhabhoni) | ~30,000 | Umsebenzi olula: ukubopha, izithintelo |
| Ibanga lama-43 | Uvavanyo oluPhezulu (ikhabhoni) | ~43,000 | Ukubopha umthwalo, ukurhuqa, ukugawula |
| Ibanga lama-70 | Uthutho (i-alloy) | ~70,000 | Ikhonkco lezothutho, ukubopha iilori |
| Ibanga lama-80 | Intsimbi ye-alloy | ~80,000 | Ikhonkco lokuphakamisa, ikhonkco lamahlathi, izixhobo zokubopha |
| Ibanga le-100 | Intsimbi ye-alloy yeprimiyamu | ~100,000 | Ukuphakamisa okunzima, iintambo, iilifti eziphezulu |
| Ibanga le-120 | Intsimbi ye-alloy ephuculweyo | ~120,000 | Ukuphakamisa izinto ezinzima ngokukodwa |
Amagama abalulekileyo ekufuneka uwaqonde:
1. Umda woMthwalo oSebenzayo (WLL):Ubunzima obukhulu obunokuphakama ngetsheyini ngokukhuselekileyo.
2. Amandla okuThamba:Ikhonkco elinamandla aphezulu linokumelana ngaphambi kokuba liqhekeke.
Uvavanyo loBungqina: 3.Uvavanyo kumthwalo othile (ngesiqhelo i-2x WLL) ukuqinisekisa ukuba akukho ziphene.
Ukugqitywa kweChain:
Nantsi isishwankathelo esifutshane sentsingiselo yazo:
1. Ezinemibala:akukho kugqitywa okanye ukugquma
2. I-oxide emnyama:I-okside emnyama okanye i-blackening yindlela yokuguqula izinto ze-ferrous, esetyenziselwa ukongeza ukumelana nokugqwala okuncinci, ukubonakala, kunye nokunciphisa ukukhanya.
3. I-electro galvanized:i-electroplating yokufaka i-zinc kumphezulu, ifakwa kwisisombululo setyuwa ye-zinc, kwaye umbane wamandla ubeka umaleko we-zinc ogudileyo, okhazimlayo, obhityileyo, ofanayo.
4. I-dip eshushu egqunywe ngesinyithi:Ibandakanya ukuntywilisela intsimbi kwi-zinc enyibilikisiweyo malunga ne-450°C, I-zinc idibana nentsimbi ukuze yenze iileya ze-zinc-iron alloy ezijiyileyo, Inika ukumelana okungcono kokugqwala ixesha elide, ingakumbi ngaphandle.
5. Umgubo ogqunywe ngomgubo: Ingubo yomgubo luhlobo lwengubo esetyenziswa njengomgubo owomileyo nohamba ngokukhululekileyo.Iingubo zomgubo zinokuvelisa iingubo ezijiyileyo kakhulu kuneengubo zolwelo eziqhelekileyo ngaphandle kokubaleka okanye ukugoba.
Phawula:Ngamabanga angama-80 nangaphezulu kuphela avunyelweyo ukuphakamisa iimoto ezithwala abantu ngaphezulu ngokwemigangatho ye-OSHA kunye ne-ASME.
Ukukhetha iChain Efanelekileyo:
1. Misela umthwalo:Yazi ubunzima kunye nokhuseleko.
2. Okusingqongileyo:Iyakonakalisa, ishushu kakhulu, njl.
3. Ukusetyenziswa:Ukuphakamisa, ukutsala, ukubopha, njl.
4. Imigaqo:I-OSHA, i-DOT, okanye enye indlela yokuthobela ikhowudi.
Isiphelo:
Ngoku ekubeni uqonda umahluko kwiindidi ezahlukeneyo zetsheyini, ungasebenza ngokukhuselekileyo kwaye ukhethe itsheyini efanelekileyo kwisicelo sakho. Kwaye ukuba ufuna itsheyini ekumgangatho ophezulu, i-G80 okanye i-G100 lifting hook, i-chain sling, okanye unemibuzo malunga nento oyifunayo, nxibelelana nathi apha eQingdao Well Done Imp & Exp Co., Ltd.. Iingcali zethu ziya kukuvuyela ukukunceda ufumane into oyifunayo.
