1.Ngokwendawo yokusetshenziswa
a.Lapho ukhetha isithwali samasondo esifanele, into yokuqala okufanele uyicabangele isisindo sokuthwala isondo le-wheel caster.Isibonelo, ezitolo ezinkulu, ezikoleni, ezibhedlela, ezakhiweni zamahhovisi nasemahhotela, iphansi lihle, libushelelezi futhi izimpahla ezihanjiswayo ngokuvamile zilula, okusho ukuthi wonke ama-caster azothwala cishe u-10 kuya ku-140kg.Ngakho-ke, inketho efanelekile isithwali sesondo sokucwenga esakhiwe kusetshenziswa inqubo yokugxiviza epuleti lensimbi elincanyana (2-4mm).Lolu hlobo lwesithwala samasondo lulula, luyagobeka, futhi luthule.
b.Ezindaweni ezinjengamafekthri nezindawo zokugcina izimpahla lapho ukuthutha kwempahla kuvame kakhulu futhi umthwalo usinda (280-420kg), sincoma ukusebenzisa isithwala samasondo esenziwe ngepuleti lensimbi eliwugqinsi elingu-5-6mm.
c.Uma isetshenziselwa ukuthwala izinto ezisindayo ezifana nalezo ezivame ukutholakala emafekthri endwangu, amafekthri ezimoto, noma amafekthri emishini, ngenxa yomthwalo omkhulu kanye nebanga elide lokuhamba, i-caster ngayinye kufanele ikwazi ukuthwala i-350-1200kg, futhi yenziwe kusetshenziswa i-8. -12mm owugqinsi steel plate wheel carrier.Isithwali samasondo esinyakazayo sisebenzisa ibhodi lendiza, futhi ibhola lifakwa epuletini elingezansi, okuvumela i-caster ukuthi ithwale umthwalo osindayo ngenkathi isalondoloze ukujikeleza okuguquguqukayo kanye nokumelana nomthelela.Sincoma ukusebenzisa amasondo e-caster enziwe enayiloni eqinisiwe engenisiwe (PA6) super polyurethane noma irabha.Ngokusekelwe ezidingweni ezithile zokufaka isicelo, ingaphinda ifakwe uthayela noma ifuthwe ngomuthi wokumelana nokugqwala, futhi inikezwe umklamo wokuvimbela omazombezombe.
d.Izindawo ezikhethekile: izindawo ezibandayo neziphezulu zokushisa zibeka ingcindezi enkulu kuma-casters, futhi emazingeni okushisa aphezulu, sincoma izinto ezilandelayo
· amazinga okushisa aphansi ngaphansi kuka -45℃: polyurethane
· amazinga okushisa aphezulu asondele noma ngaphezulu kuka-230℃: ama-swivel caster akhethekile amelana nokushisa
2.Ngokomthamo wokuthwala
Ngesikhathi sokukhethwa kwamandla okuthwala ama-casters, abasebenzisi kudingeka bacabangele amamajini athile okuphepha.Sisebenzisa amasondo amasondo asetshenziswa kakhulu njengesibonelo, nakuba ukukhetha kufanele kwenziwe ngokusekelwe kulezi zindlela ezimbili ezilandelayo:
a.Ama-casters ama-3 anesisindo sonke: Omunye wabakhangisi kufanele amiswe.Le ndlela ilungele ukusetshenziswa lapho ama-casters ethwala umfutho omkhulu phezu kwezimo ezimbi zomhlaba ngenkathi kuthuthwa impahla noma okokusebenza, ikakhulukazi ezilinganisweni ezinkulu, ezisindayo eziphelele zesisindo.
b.Ama-casters angu-4 anesisindo esiphelele se-120%: Le ndlela ifanele izimo zomhlabathi ezinhle, futhi umthelela kuma-casters amancane ngesikhathi sokunyakaza kwempahla noma imishini.
c.Bala umthamo wokuthwala: ukuze ubale umthamo womthwalo odingwa ama-casters, kuyadingeka ukwazi isisindo esibulalayo semishini yokulethwa, umthwalo omkhulu kanye nenani lamasondo e-caster nama-caster asetshenzisiwe.Umthamo womthwalo odingekayo wesondo le-caster noma i-caster ibalwa kanje:
T= (E+Z)/M×N
---T= isisindo sokulayisha esidingekayo sesondo le-caster noma i-caster
---E= i-deadweight yemishini yokulethwa
---Z= umthamo omkhulu
---M= inani lamasondo e-caster nama-caster asetshenzisiwe
---N= Isici sokuphepha (cishe 1.3 - 1.5).
Kufanele kuqashelwe amacala lapho abalingisi bezovezwa inani elibalulekile lomthelela.Akufanele kuphela kukhethwe i-caster enamandla okuthwala umthwalo omkhulu, kodwa nezakhiwo zokuvikela umthelela eziklanywe ngokukhethekile kufanele zikhethwe.Uma kudingeka ibhuleki, kufanele kukhethwe amabhuleki anebhuleki elilodwa noma amabili.
· amazinga okushisa aphansi ngaphansi kuka -45℃: polyurethane
