Posankha ma caster, anthu ambiri amada nkhawa ndi nkhani ziwiri: ngati ndi otetezeka kuwakankhira komanso ngati ndi olimba kuti agwiritsidwe ntchito kwa nthawi yayitali. Chinsinsi cha kuthekera kwa ma caster ofewa a rabara kuti agwirizane mbali zonse ziwiri chili mu kulimba kwa chinthucho, kapangidwe ka pamwamba, ndi kapangidwe ka mkati mwa bearing. Ma caster ofewa a rabara nthawi zambiri amagwiritsa ntchito zinthu zotanuka monga TPR, zomwe ndizoyenera pazochitika zomwe zimafuna phokoso, chitetezo cha pansi, komanso chitonthozo mukamagwiritsa ntchito.
1. N’chifukwa chiyani ma casters ofewa a mphira angapangitse kuti pakhale bata?
Zipangizo zofewa za rabara zimakhala ndi kusinthasintha kwabwino. Zipangizo zopopera zikagundana ndi nthaka, pamwamba pa gudumu padzakhala kusintha kwina, komwe kumatha kufalitsa kuthamanga kwa kukhudzana ndikuchepetsa phokoso la kugwedezeka komwe kumachitika chifukwa cha kugundana kolimba. Ichi ndi chifukwa chachikulu chomwe chimakhala chete pamalo olimba monga matailosi, pansi pa epoxy, ndi terrazzo.
Kuphatikiza apo, mphira wofewa umakhala ndi mphamvu inayake yoyamwa pa kugwedezeka. Chipangizocho chikakumana ndi mipata yaying'ono, tinthu ta pansi, kapena kusalingana pang'ono panthawi yoyenda, pamwamba pa gudumu limatha kuyamwa kaye kugwedezeka kenako nkutumiza ku bulaketi ndi thupi la chipangizocho, zomwe zimapangitsa kuti phokoso lonse likhale lochepa komanso kuti phokoso likhale losalala.
Ngati ma bearing olondola agwiritsidwa ntchito mkati mwa ma casters, kukana kwa ma roll kudzachepa kwambiri. Mawilo amazungulira bwino kwambiri, kuchepetsa kukangana ndi chibwibwi, zomwe sizimangochepetsa phokoso komanso kuchepetsa kugwedezeka mukamagwiritsa ntchito.
2. Kodi chifukwa chiyani ma casters ofewa a rabara sakutha?
Anthu ambiri amaganiza kuti 'zofewa' zikutanthauza kuti sizili zolimba, koma izi sizowona konse. Ma casters a rabara ofewa apamwamba nthawi zambiri amakula bwino chifukwa cha kukana kukalamba kudzera mu kapangidwe ka zinthu ndi kukonza pamwamba. Gawo la pamwamba pa gudumu ndi lolimba, ndipo coefficient ya kukangana imayendetsedwa bwino. Munthawi yogwiritsidwa ntchito bwino, sizophweka kumva kusweka, kusweka, komanso kuwonongeka kosazolowereka.
Nthawi yomweyo, ma casters ofewa a rabara amatha kufalitsa mphamvu pozungulira, popanda kukakamiza kwambiri m'malo am'deralo monga zipangizo zolimba. Mwanjira imeneyi, kuwonongeka kwa pamwamba pa gudumu kumakhala kofanana, ndipo nthawi yogwira ntchito ya ma casters nthawi zambiri imakhala yokhazikika.
Kwa magaleta apakhomo, magaleta ogwiritsira ntchito zida, magaleta odyera, ndi magaleta a zomera omwe amafunika kusunthidwa pafupipafupi, kukana kuwonongeka sikungowonekera kokha chifukwa chakuti pamwamba pa gudumu sipamangika mosavuta, komanso chifukwa cha kuthekera kosunga magwiridwe antchito abwino mutagwiritsa ntchito nthawi yayitali.
3. Ndi nyumba ziti zomwe zingathandize kwambiri ogwiritsa ntchito
Kuwonjezera pa zipangizo za pamwamba pa mawilo, mabearing, mabracket, ndi mabuleki zimakhudzanso mwachindunji magwiridwe antchito a ma casters. Mawilo okhala ndi mabearing olondola amapereka kuzungulira kosavuta, koyenera zochitika zomwe zimafuna kuzunguliridwa pafupipafupi komanso kukankhidwa tsiku ndi tsiku.
Kapangidwe kake ka zinthu zonse kangathandize kuti chiwongolero chizigwira bwino ntchito, pomwe kapangidwe ka mabuleki awiri kangasinthe mwachangu pakati pa kuyenda ndi malo oimika magalimoto, zomwe zimalepheretsa ngolo kapena zida kuti zisapitirire kutsetsereka zikafunika kukonzedwa. Mtundu uwu wa kasinthidwe ndi wothandiza kwambiri pazochitika zapakhomo, zamalonda, komanso zamafakitale.
Ngati pali kuipitsidwa kwa mafuta, nthunzi ya madzi, kapena kayendetsedwe ka chiwongolero chapamwamba kwambiri pamalo ogwiritsidwa ntchito, chisamaliro chiyeneranso kuperekedwa ku mphamvu zotetezera za mabulaketi ndi mabearing. Kusankha zipangizo zoyenera ndikofunikira kuti mawilo akhale osavuta kukankhira komanso olimba.
