1. Malire Ogwira Ntchito Pamaketani a Zitsulo Zozungulira
Kaya mumanyamula makina, mumagwiritsa ntchito maunyolo, kapena muli pantchito yodula mitengo, ndikofunikira kudziwa malire a unyolo womwe mukugwiritsa ntchito.Unyolo uli ndi malire ogwirira ntchito- kapena WLL- pafupifupi gawo limodzi mwa magawo atatu a mphamvu zawo zopuma (kuchuluka kwa mphamvu zomwe maunyolo amatha kupirira asanaduke).
Gawo la unyolo ndi m'mimba mwake zimatsimikizira malire a ntchito ya unyolo.Chain imakongoletsedwa ndi kalasi ndi kukula kwake kotero kuti mutha kudziwa WLL yake pogwiritsa ntchito tchatichi.
2. Mitundu ya unyolo
Grade 30 ndi ntchito zambiri, ndalama zambiri.Zomwe zimadziwikanso kuti Grade 30 Proof Coil Chain, anthu amagwiritsa ntchito mankhwalawa m'mafakitale ndi ntchito zosiyanasiyana, kuphatikizapo zomangamanga zopepuka, zotchinga, komanso m'makampani apanyanja.Sibwino kukweza pamwamba.Unyolo wa Grade 30 umasindikizidwa pogwiritsa ntchito 3, 30, kapena 300.
Amatchedwanso Grade 43 High Test Chain kapena Grade 43 Tow Chain, izi ndizofala m'mafakitale okokera ndi kudula mitengo.Osagwiritsa ntchito unyolowu pokweza pamwamba.Unyolo uwu umaphatikizapo mapangidwe ojambulidwa pogwiritsa ntchito 43 kapena G4.
Gulu la 70 Transport Chain, lomwe limatchedwanso "Grade 70 Truckers Chain," limagwira ntchito yopezera katundu wonyamula anthu pamsewu.Osagwiritsa ntchito tchenichi pokweza m'mwamba.Unyolo uwu umaphatikizapo mapangidwe ojambulidwa pogwiritsa ntchito 7, 70, kapena 700.
Grade 80 Alloy Chain imagwira ntchito yokweza pamwamba chifukwa cha kapangidwe kake kotetezedwa ndi kutentha.Anthu nthawi zambiri amagwiritsa ntchito unyolo wamtunduwu ngati unyolo wolemetsa.Gulu la 80 unyolo umaphatikizapo mapangidwe ojambulidwa pogwiritsa ntchito 8, 80, kapena 800.
Unyolo womwe umaganiziridwa kuti ndi wapamwamba kwambiri, umapereka pafupifupi 25% kuchuluka kwa ntchito zolemetsa kuposa unyolo wa Giredi 80.Ndibwino kuti munyamule pamwamba.Unyolo wa Gulu la 100 umaphatikizapo mapangidwe ojambulidwa ndi 10 kapena 100.
Chogulitsa chatsopano pamsika, unyolo wa Giredi 120 ndi wamphamvu mpaka 50% kuposa unyolo wa Giredi 80 ndi 20% wamphamvu kuposa unyolo wa Giredi 100.Imalimbananso ndi abrasion kuposa maunyolo onse a Giredi 80 ndi Giredi 100.Ndi zotetezeka kukwera pamwamba.
3. Phunzirani zambiri za kusiyana pakati pa giredi 70, 80 ndi 100 apa:
Funso lomwe gulu lathu lamalonda limamva kuchokera kwa makasitomala pazamalonda athu ndi "Kodi pali kusiyana kotani pakati pa giredi 70, 80, 100, ndi chain 120?"Timalongosola kusiyana pakati pa maguluwa ndi maunyolo omwe muyenera kugwiritsa ntchito malinga ndi zosowa zanu.
Gawo la 70 Chain
Unyolo wa Grade 70 umapangidwa ndi chitsulo chotenthetsera mpweya.Zomwe zimadziwikanso kuti "ma chain chain," anthu amagwiritsa ntchito giredi 70 ngati zomangira pama trailer apamsewu.Osagwiritsa ntchito unyolowu pokweza pamwamba.
Mtundu uwu nthawi zambiri umakhala ndi golide wa chromate kotero ndikosavuta kuzindikira.Imakumananso ndi California Highway Patrol ndi zofunikira za DOT.Zomwe zimagwiritsidwa ntchito pa unyolowu, kuwonjezera pa zoyendera, zimaphatikizanso kukoka, kudula mitengo, zida zamafuta, komanso kugwiritsa ntchito chitetezo.
Unyolo uwu umaphatikizapo mapangidwe ojambulidwa ndi 7, 70, kapena 700.
80 unyolo ndi unyolo wachitsulo wotenthedwa ndi kutentha wokhala ndi chiŵerengero champhamvu cha kulemera.Mphamvu zake zimapangitsa kuti zikhale zotetezeka kukweza pamwamba ndi kukweza masing'i.Ndibwinonso kugwiritsa ntchito monga kuchira, chitetezo, ndi unyolo wokokera.
Unyolo uwu ukuchulukirachulukira m'makampani oyendetsa magalimoto amtundu wa flatbed kuti ateteze katundu wolemetsa wamakampani.Chifukwa maunyolo amtunduwu nthawi zambiri amakhala ndi mbedza yamtundu wina wa clevis grab hook, ndipo misonkhano yotereyi sivomerezedwa kukweza pamwamba.
Unyolo uwu umaphatikizapo mapangidwe ojambulidwa ndi 8, 80, kapena 800.
Gawo la 80 Chain
Gulu la 100 Chain
Unyolo wa Grade 100 ndi chinthu chatsopano ndipo ukuchulukirachulukira m'malo mwa unyolo wa giredi 80.Omwe amaganiziridwa kuti ndi apamwamba kwambiri ndi opanga, amapereka malire opitilira 25% apamwamba kuposa giredi 80 ndipo amagwira ntchito yokweza pamwamba.
Anthu ambiri amagwiritsa ntchito giredi 100 kupitilira giredi 80 kuti ateteze katundu wophwathidwa.Unyolo uwu uli ndi mphamvu zowonjezera ndi kukula kochepa komwe sikutsutsana ndi malire a ntchito.
Komabe, chifukwa maunyolowa nthawi zambiri amakhala ndi mbedza yamtundu wina wa clevis grab hook, ndipo misonkhano yotereyi sivomerezedwa kuti ikwezedwe pamwamba.
Unyolo uwu umaphatikizapo mapangidwe ojambulidwa ndi 10, 100, kapena 1000.
Gulu la 120 unyolo ndi gulu latsopano la unyolo wapamwamba kwambiri, wopatsa mphamvu kwambiri pamsika.Mawonekedwe a square link amapangitsa kulumikizana kwambiri pakati pa malo onyamula pamalumikizidwe, zomwe zimachepetsa kukakamiza kwa unyolo.
Izi zikutanthawuza ku malire olemetsa ogwira ntchito omwe ndi 50% apamwamba kuposa giredi 80, ndi 20% apamwamba kuposa giredi 100. Unyolo giredi 120 umagwira ntchito yokweza pamwamba.Ndikofunika kuzindikira kuti monga momwe zilili ndi magulu a tcheni a Giredi 80 ndi magulu a tcheni a Giredi 100, ma tcheni ophatikizana nawonso sali otetezeka kukweza pamwamba chifukwa cha mtundu wa mbedza zomwe zimagwiritsidwa ntchito.
Mtundu uwu wa unyolo uli ndi mapeto a buluu owala kuti adziwike mosavuta.
Gawo la 120 Chain
Mosasamala mtundu wa unyolo, onse ayenera kutsatira mfundo zokhazikitsidwa ndi National Association of Chain Manufacturers (NACM), zomwe zikuphatikizapo:
- Osanyamula kapena kuyimitsa katundu wokwezedwa pamwamba pa anthu.
- Kuyang'ana maunyolo nthawi ndi nthawi kuti muwone ming'alu, ma gouges, kuvala, kutalika, ma nick, komanso kukwanira.
- Kutentha kwambiri kapena kukhudzana ndi malo okhala ndi mankhwala monga ma asidi kapena zinthu zamadzimadzi zowononga kapena utsi kutha kuchepetsa kugwira ntchito kwa tcheni.
- Funsani ndi wopanga unyolo ngati maunyolo agwira ntchito kunja kwa kutentha komwe akuyenera ( -40 °F mpaka 400 °F).
- Chotsani unyolo pautumiki ngati makulidwe pagawo lililonse pa ulalowo ndi wocheperapo mtengo womwe watchulidwa.
- Posakaniza maunyolo kapena mitundu ya zigawo, zonse ziyenera kuvoteredwa pamlingo wolemetsa wa gawo lotsika kwambiri kapena unyolo.
- Sakatulani zomwe tasankha za mayendedwe a giredi 70, komanso maunyolo.
