Ukukhethwa kwama-casters: kusukela ekusetshenzisweni, ukuthwala umthwalo kanye nempahla yemibono emithathu

I-Casters, ingxenye ebonakala ilula, empeleni idlala indima ebalulekile ekuphileni. Kusukela emishinini yefekthri kuya emishinini yefenisha, kuya kumatroli esuphamakethe kanye nemibhede yezokwelapha, ungabona isibalo sayo. Kodwa indlela yokukhetha i-caster efanele ngokuvumelana nezidingo zangempela? Izici ezintathu ezilandelayo okufanele uziphendule.
Okokuqala, ukusetshenziswa okucacile
1. Ukusetshenziswa kwemboni: esetshenziswa ezimbonini noma emishinini yemishini, egxile ekuthwaleni umthwalo, ingakhetha ama-casters-duty-duty.
2. Ukusetshenziswa kwefenisha: ngemishini yehhovisi noma ifenisha, egxile kubuhle, ingakhetha isondo le-PP (polypropylene) noma isondo le-PVC (i-polyvinyl chloride).
3. Ukusetshenziswa kwesuphamakethe: okusetshenziselwa amashalofu noma izinqola zokuthenga, kudinga ukuguquguquka, kungakhetha ama-casters alula.
4. Izicelo zezokwelapha: zemibhede yasesibhedlela noma izinqola, ezigxile ekuthuleni nasekumelaneni nokugqwala, amasondo enjoloba angasetshenziswa.

Okwesibili, cabangela ukuthwala umthwalo
1. Ama-Casters anzima: 220-610kg, afanele imishini esindayo.
2. Ama-casters aphakathi nendawo: 100-190kg, afanele imishini evamile.
3. Ama-Casters alula: 10-100kg, afanele izinto ezingasindi.
Qaphela: Usayizi wama-casters akuwona omkhulu kangcono, kodwa futhi udinga ukucabangela ukushuba kwamabakaki, ama-bearings nezinye izici.
Ukukhetha impahla efanele
1. Isondo le-PP (i-polypropylene): alikwazi ukugqokwa, alikwazi ukumelana nomthelela, lilungele izindawo ezihlukahlukene.
2. Isondo le-polyurethane: lithambile, kodwa umsindo omncane.
3. Isondo lerabha: umsindo othambile, ophansi, vikela phansi.
4. Isondo le-TPR: umsindo othambile, ophansi, ofana nerabha.
5. Isondo lenayiloni: alikwazi ukugqokwa, lithwala kakhulu.
Ukwengeza, izindawo ezikhethekile (njengamalabhorethri, izinga lokushisa eliphezulu, umswakama, njll.) zidinga ukuphasa izivivinyo ezifanele ngaphambi kokusetshenziswa.
