1. Ngokusho kwendawo yokusetshenziswa
a.Uma ukhetha isithwali samasondo esifanele, into yokuqala okufanele uyicabangele isisindo sokuthwala isondo. Isibonelo, ezitolo ezinkulu, ezikoleni, ezibhedlela, ezakhiweni zamahhovisi nasemahhotela, phansi kuhle, kubushelelezi futhi izimpahla ezihanjiswayo zivame ukuba lula, okusho ukuthi isithwali ngasinye sizothwala cishe amakhilogremu ayi-10 kuya kwangu-140. Ngakho-ke, inketho efanelekile isithwali samasondo esinamapulangwe esakhiwe ngenqubo yokunyathela epuletini elincane lensimbi (2-4mm). Lolu hlobo lwesithwali samasondo lulula, luyaguquguquka, futhi luthule.
b.Ezindaweni ezifana nezimboni kanye nezindawo zokugcina impahla lapho ukuthutha imithwalo kuvame kakhulu futhi umthwalo usinda kakhulu (280-420kg), sincoma ukusebenzisa isithwali samasondo esenziwe ngepuleti lensimbi eliwugqinsi oluyi-5-6mm.
c.Uma isetshenziselwa ukuthwala izinto ezisindayo njengalezo ezivame ukutholakala ezimbonini zezindwangu, ezimbonini zezimoto, noma ezimbonini zemishini, ngenxa yomthwalo omkhulu kanye nebanga elide lokuhamba ngezinyawo, i-caster ngayinye kufanele ikwazi ukuthwala ama-350-1200kg, futhi ikhiqizwe kusetshenziswa i-steel plate wheel carrier engu-8-12mm ubukhulu. I-movable wheel carrier isebenzisa i-plane ball bearing, futhi i-ball bearing ifakwe epuletini elingezansi, okuvumela i-caster ukuthi ithwale umthwalo osindayo ngenkathi isagcina ukujikeleza okuguquguqukayo kanye nokumelana nokushayisana. Sincoma ukusebenzisa amasondo e-caster enziwe nge-induction reinforced nylon (PA6) super polyurethane noma irabha. Ngokusekelwe ezidingweni ezithile zokusetshenziswa, ingaphinde ifakwe i-galvanized noma ifuthwe ngokwelashwa kokumelana nokugqwala, kanye nokunikezwa umklamo wokuvimbela ukugoba.
d.Izindawo ezikhethekile: izindawo ezibandayo nezinokushisa okuphezulu zibeka ukucindezeleka okukhulu kuma-casters, futhi emazingeni okushisa aphezulu, sincoma izinto ezilandelayo
· amazinga okushisa aphansi ngaphansi kuka -45℃: i-polyurethane
· amazinga okushisa aphezulu aseduze noma angaphezu kuka-230℃: ama-caster ajikelezayo akhethekile angashisi ukushisa
2. Ngokusho komthamo wokuthwala
Ngesikhathi sokukhetha umthamo wokuthwala wama-caster, abasebenzisi kudingeka bacabangele imingcele ethile yokuphepha. Sisebenzisa ama-caster anamasondo amane asetshenziswa kakhulu njengesibonelo, yize ukukhetha kufanele kwenziwe ngokusekelwe ezindleleni ezimbili ezilandelayo:
a.Ama-caster amathathu athwala yonke isisindo: Elinye lama-caster kufanele lilengiswe. Le ndlela ifanele ukusetshenziswa lapho ama-caster ethwala umfutho omkhulu phezu kwezimo zomhlaba ezimbi ngenkathi ethutha izimpahla noma imishini, ikakhulukazi enanini elikhulu nelisindayo lesisindo sonke.
b.Ama-caster angu-4 anesisindo esingu-120%: Le ndlela ifaneleka ezimweni zomhlabathi ezinhle, futhi umthelela kuma-caster mncane kakhulu ngesikhathi sokunyakaza kwezimpahla noma imishini.
c.Bala umthamo wokuthwala: ukuze kubalwe umthamo womthwalo odingwa yizicashi, kubalulekile ukwazi isisindo esingapheli semishini yokulethwa, umthwalo omkhulu kanye nenani lamasondo e-caster kanye nezicashi ezisetshenzisiwe. Umthamo womthwalo odingekayo wesondo le-caster noma i-caster ubalwa kanje:
T= (E+Z)/M×N
---T= isisindo sokulayisha esidingekayo esondweni noma e-caster
---E= isisindo esinzima semishini yokulethwa
---Z= umthwalo omkhulu
---M= inani lamasondo e-caster nama-caster asetshenzisiwe
---N= Isici sokuphepha (cishe 1.3 - 1.5).
Kufanele kuqashelwe izimo lapho ama-caster ezobe evezwe khona emngciphekweni omkhulu. Akumelwe nje kukhethwe i-caster enomthamo omkhulu wokuthwala umthwalo, kodwa kufanele kukhethwe nezakhiwo zokuvikela umthelela eziklanywe ngokukhethekile. Uma kudingeka ibhuleki, ama-caster anamabhuleki angawodwa noma amabili kufanele akhethwe.
· amazinga okushisa aphansi ngaphansi kuka -45℃: i-polyurethane
