Caster ndi chowonjezera chofunikira cha chonyamulira, chonyamulira chachikulu chimagwiridwa ndi dzanja kapena kukokedwa, posankha chonyamulira, muyenera kutengera kugwiritsa ntchito zida ndi kugwiritsa ntchito zinthu zachilengedwe, kuti musankhe chonyamulira choyenera.
Choyamba, mukasankha ma caster, muyenera kuganizira mtundu wa pansi womwe mukugwiritsa ntchito pamalopo? Kodi ndi konkire kapena marble? Kodi pansi ndi yofewa kapena yolimba? Kodi mukufuna chitetezo chapamwamba pa pansipo?
Kutengera ndi momwe zinthu zilili, tikupangira nayiloni kapena polyurethane yamphamvu kwambiri (TPU) ya pansi pa konkire, ndi mawilo a rabara kapena polyurethane yopangidwa ndi chitsulo (PU) ya pansi pa marble kapena matabwa.
Kusintha zinthu zomwe zili pamwamba pa mawilo a ma casters anu kudzakuthandizani kuti muzigwiritsa ntchito bwino kwambiri.
Chachiwiri. Kodi mphamvu ndi liwiro la ntchito ndi lotani? Mukayenda mwachangu, ma caster amafunika mphamvu zambiri. Kukula kwa caster, m'lifupi ndi zinthu zonse zimakhudza kuchuluka kwa kulemera komwe caster inganyamule pa liwiro lalikulu kapena lotsika.
Kuti mudziwe kuchuluka kwa katundu wofunikira pa chotsukira chilichonse pa ngolo, gawani kuchuluka kwa katundu wa ngolo ndi chiwerengero cha chotsukira. Kenako chulukitsani zotsatirazi ndi chitetezo chomwe chimadalira momwe ntchitoyo ikuyendera.
C = Kulemera kofunikira kwa ma casters
L = Kulemera kwakukulu kwa ngolo
W = Kulemera kwa ngolo
n = chiwerengero cha ma casters omwe agwiritsidwa ntchito
SF = Chitetezo
Kuyendetsa mkati mwa nyumba = 1.35 (yosakwana 3 mph)
Kuyenda panja ndi manja = 1.8 (yosakwana 3 mph)
Mayendedwe amkati oyendetsedwa ndi mphamvu = 2 (osakwana 3 mph)
Mayendedwe akunja oyendetsedwa ndi mphamvu = 3 (osakwana 3 mph)
Chitsanzo chotsatirachi ndi njira yosavuta yogwiritsira ntchito ngolo yokhazikika ya 4-caster yokhala ndi ma caster awiri ozungulira komanso awiri ozungulira, okhala ndi kulemera kofanana pa gudumu lililonse pansi pa kayendedwe kamanja mkati:
C = Kulemera kofunikira pa ma casters
L = Kulemera kwakukulu kwa trolley
W = Kulemera kwa ngolo
Mwachitsanzo, taganizirani ngolo yolemera makilogalamu 300 yokhala ndi katundu wa makilogalamu 1,800. Izi zitha kugawidwa ndi makilogalamu 2,100 ndi 3. Pa katundu uyu, caster iliyonse iyenera kugwirizira/kuyesedwa kuti ikhale ndi makilogalamu 700 kapena kuposerapo.
Zinthu zina ziyenera kuyesedwa kuti zidziwike bwino momwe caster imagwiritsidwira ntchito, monga: kasinthidwe ka caster, kutentha kwa malo, kayendedwe ka ntchito, zida zopondaponda, ndi liwiro (mawilo okhala ndi ma bearing a mpira adzakhala ndi mphamvu yocheperako yonyamula katundu pa liwiro loposa 3 mph).
Monga mwachizolowezi, akatswiri athu a mayankho akhoza kukambirana za momwe mungagwiritsire ntchito kuti atsimikizire kuti caster yoyenera ikugwiritsidwa ntchito, chifukwa caster si mawilo okha.
Chachitatu, kodi kutentha kwa malo komwe amagwiritsidwa ntchito ndi kotani? Kodi ma casters amagwiritsidwa ntchito m'nyumba kapena panja? Pakugwiritsa ntchito kwenikweni, kutentha kwakukulu ndi kochepa kudzakhudza momwe caster imagwirira ntchito pamlingo winawake.
Chachinayi, kodi zinthu zapadera zomwe zingagwiritsidwe ntchito ndi ziti? Kodi pali zinyalala? Kodi pali chinyezi kapena mankhwala owopsa? Kodi dzuwa lidzatentha nthawi zonse zinyalala zanu? Kodi magetsi osasunthika adzapita ku zinyalalazo ndikuwononga zinthu zamtengo wapatali?
Mafunso onsewa ndi ena ambiri ayenera kulowetsedwa mu ndondomeko yopanga zisankho.
Ngati muli ndi mafunso ambiri okhudza kusankha okonda kuponya, musazengereze kulankhulana nafe mwachinsinsi.
