Kodi ma profiles a aluminiyamu a chipinda choyera ndi otani?

Mawu akuti mbiri ya aluminiyamu ndi dzina lathunthu mumakampani, lomwe pakati pawo mbiri ya aluminiyamu ya mafakitale ndi mbiri ya aluminiyamu yomanga ndiye zazikulu. Mbiri ya aluminiyamu yomwe imagwiritsidwa ntchito pomanga chipinda choyera ndi mbiri ya aluminiyamu ya mafakitale.
Mbiri ya aluminiyamu yomwe ingagwiritsidwe ntchito ngati chipinda choyera iyenera kukwaniritsa zofunikira zingapo: 1. Sikophweka kuipitsidwa ndi fumbi komanso kosavuta kuyeretsa. Chifukwa chipinda choyera chili ndi zofunikira zambiri pa malo ozungulira aukhondo, palibe fumbi konse. 2. Kaya mphamvu ya bearing ndi yokwanira. Ogwiritsa ntchito osiyanasiyana amapanga zipinda zoyera zokhala ndi zofunikira zosiyanasiyana, kotero padzakhala kusiyana kwa mafotokozedwe. Chifukwa chake, mphamvu yake ya bearing ndi chizindikiro chofunikira kwambiri pakusankha.
Mafotokozedwe akuluakulu ndi mitundu ya ma profiles a aluminiyamu a zipinda zoyera ndi awa: 3030, 3040, 3060, 3090, 30120, 3838, 4040, 4060, 4090, 5050, 6060 ndi 8080. Pakati pa mitundu iyi, 3030, 4040 ndi 5050 pali mitundu itatu yomwe ogwiritsa ntchito amagwiritsa ntchito kwambiri. Komabe, mitundu ina si yabwino kwambiri pakugwira ntchito bwino komanso kugwiritsa ntchito bwino pomanga zipinda zoyera, kotero ogwiritsa ntchito ochepa okha ndi omwe adzasankhidwe.
