Pogula ma casters, tiyenera kulabadira zinthu za casters, chifukwa zinthu za casters zimagwirizana mwachindunji ndi chitonthozo, kulimba ndi chitetezo cha ntchito. M'nkhaniyi, tikuwonetsani momwe tingadziwire zinthu za caster kuchokera kuzinthu ziwiri za mawonekedwe oyaka moto ndi coefficient ya kuvala.
Kuwotcha Makhalidwe
Makasitomala opangidwa ndi zinthu zosiyanasiyana amawonetsa mawonekedwe osiyanasiyana akawotchedwa, chomwe ndi chinthu chofunikira chomwe tingagwiritse ntchito kuzindikira zinthuzo. Makamaka:
Nayiloni (PA): yosavuta kuyaka, kuyaka lawi lachikasu, fungo la misomali, fungo laubweya woyaka, kutulutsa utsi woyera, kuyaka pamwamba, madontho osungunuka.
Polyurethane (PU): yosavuta kuyaka, kuyaka ndi utsi woyera wofewa, wosavuta kusungunuka, wopanda fungo loyipa, silika womata.
Polyvinyl chloride (PVC): yosavuta kuyaka, kuyaka ndi utsi wakuda wakuda, fungo loyipa, kuyaka popanda silika womata, pamwamba pakuwotcha ufa wakuda wa carbon.
Polypropylene (PP): yosavuta kuyaka, pali fungo la pulasitiki lopanda mphamvu, kutentha pamwamba pa yunifolomu kusungunuka, ndi silika womata. Nayiloni (PA): yosavuta kuwotcha, kuyaka ndi fungo la tsitsi loyaka, pambuyo pakuwotcha pamwamba kumakhala ndi matuza, komanso silika womata.
Abrasion resistance
Kukaniza kuvala kwa ma casters ndichinthu chofunikira kwambiri chomwe chimakhudza moyo wautumiki, ndipo coefficient ya kuvala ya ma casters opangidwa ndi zinthu zosiyanasiyana ndi yosiyana. Makamaka:
Gudumu la nayiloni: kukana kwa magudumu a nayiloni kulinso kwabwinoko, koyenera kugwiritsidwa ntchito pamtunda wamsewu, koma wachibale wa gudumu la mphira ndiwotsika pang'ono.
Gudumu la rabara: gudumu la mphira lili ndi kukana kwabwino kwa abrasion, limatha kuzolowera malo osiyanasiyana amsewu, moyo wautali wautumiki.
PVC gudumu: PVC gudumu ali osauka abrasion kukana, zosavuta kuvala ndi zikande, moyo waufupi utumiki.
Wheel mphira wofewa: gudumu la rabara lofewa limakhala ndi kukana bwino kwa abrasion, koma ndilotsika pang'ono poyerekeza ndi gudumu la rabala.
Chifukwa chake, titha kuweruza zinthuzo poyang'ana kung'ambika ndi kung'ambika kwa oponya pakugwiritsa ntchito ndikumvetsetsa ma coefficients okana kuvala azinthu zosiyanasiyana.
Tiyenera kuzindikira kuti zomwe zili pamwambazi ndi mbali ziwiri zokha za zinthu za caster. Ndipotu, palinso zinthu zina za caster, monga kulemera ndi mphamvu, zomwe zidzakhudzanso ntchito ya caster. Chifukwa chake, pogula zida, tiyenera kuganizira mozama zinthu zingapo ndikusankha tokha zinthu zoyenera.
