KUSANGALALA
NJIRA
Akatswiri opanga caster, tadzipereka kupanga zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yamakampani.
1 - Dziwani kuchuluka kwa katundu wa caster
Kulemera konse kwa zida zonyamulira, kuchuluka kwa katundu, ndi kuchuluka kwa mawilo amodzi kapena ma caster omwe amagwiritsidwa ntchito ayenera kufotokozedwa kuti awerengere kuchuluka kwa katundu wa ma caster osiyanasiyana.
Kuwerengera kuchuluka kwa katundu wa gudumu limodzi kapena caster ngati kuli kofunikira kumawoneka motere: T = M x N (E + Z).T ndiye mphamvu yonyamula katundu pa gudumu limodzi kapena caster, E ndiye kulemera kwa zida zonyamulira, Z ndiye kuchuluka kwake, M ndi kuchuluka kwa mawilo amodzi kapena ma caster omwe amagwiritsidwa ntchito, ndipo N ndiye chitetezo (pafupifupi 1.3 mpaka 1.5).
2 - Sankhani gudumu kapena zinthu za caster.
M'lifupi mwamsewu, zotchinga, zinthu zotsalira m'malo ogwiritsira ntchito (monga mafuta ndi chitsulo), malo ozungulira, ndi malo apansi, zonse ziyenera kuganiziridwa (monga kutentha kwambiri kapena kutentha pang'ono, chinyezi; pansi pa kapeti, pansi pa konkriti, matabwa. pansi etc.)
Madera osiyanasiyana apadera amatha kugwiritsa ntchito zoponya mphira, zoyikapo za PP, zoyika za nayiloni, zotulutsa za PU, zotulutsa za TPR, ndi ma anti-static casters.
3. Sankhani diameter ya caster.
Kulemera kwake komanso kuyenda kosavuta kumawonjezeka ndi mainchesi a caster, omwe amatetezanso pansi kuti zisawonongeke.
Mphamvu yolemetsa yofunikira iyenera kutsogolera kusankha kwa caster diameter.
4 - Sankhani zosankha zoyikapo za caster.
Malinga ndi kapangidwe ka zida zoyendera, mitundu yokwezera nthawi zambiri imaphatikizira Kuyika kwapamwamba kwambiri, Kuyika tsinde kwa Threaded, Stem and Socket fitting, Grip ring ring, Kukulitsa tsinde, ndi Stemless fitting.
5 - Sankhani njira yabwino kwambiri ya caster.
Pamaziko a zomwe tatchulazi, titha kukupatsirani njira yabwino kwambiri ya caster kapena kupanga zisankho zatsopano pazida zanu.
