Cov caster yog ib qho khoom siv tseem ceeb ntawm lub cab kuj, feem ntau ntawm cov cab kuj yog tuav tes lossis rub, koj xaiv cov casters, yuav tsum tau ua raws li kev siv cov khoom siv thiab kev siv cov yam ntxwv ib puag ncig, thiab xaiv cov casters sib xws.
Ua ntej tshaj plaws, thaum koj xaiv cov casters, koj yuav tsum xav txog hom pem teb uas koj siv rau qhov chaw ntawd? Puas yog nws yog concrete lossis marble? Puas yog pem teb mos lossis tawv? Koj puas xav tau kev tiv thaiv siab rau pem teb?
Nyob ntawm seb siv li cas, peb xav kom siv nylon lossis polyurethane muaj zog heev (TPU) rau cov plag tsev pob zeb dav dav, thiab cov log roj hmab lossis polyurethane cam khwb cia (PU) rau cov plag tsev marble lossis ntoo sab hauv tsev.
Kev hloov cov khoom siv ntawm lub log ntawm koj cov casters yuav cia koj ua kom lawv muaj txiaj ntsig zoo tshaj plaws.
Qhov thib ob. Lub peev xwm hnyav thiab qhov ceev ntawm daim ntawv thov yog dab tsi? Qhov koj txav mus sai dua, qhov muaj peev xwm hnyav ntau dua uas cov casters xav tau. Lub cheeb tsam ntawm caster, dav thiab cov khoom siv txhua yam cuam tshuam rau qhov hnyav uas tus caster tuaj yeem nqa tau ntawm qhov ceev siab lossis qis.
Yuav kom paub qhov peev xwm thauj khoom uas xav tau rau txhua tus neeg tsav tsheb ntawm lub laub, faib qhov thauj khoom ntau tshaj plaws ntawm lub laub los ntawm tus naj npawb ntawm cov neeg tsav tsheb. Tom qab ntawd muab qhov tshwm sim no los ntawm qhov ntsuas kev nyab xeeb uas nyob ntawm cov xwm txheej ntawm daim ntawv thov.
C = Lub peev xwm thauj khoom ntawm cov casters yuav tsum tau muaj
L = Qhov siab tshaj plaws ntawm lub laub thauj khoom
W = Qhov hnyav ntawm lub laub
n = tus naj npawb ntawm cov casters siv
SF = Qhov Kev Nyab Xeeb
Kev thauj mus los hauv tsev siv tes = 1.35 (tsawg dua 3 mph)
Kev thauj mus los sab nraum zoov = 1.8 (tsawg dua 3 mph)
Kev thauj mus los hauv tsev uas siv lub zog fais fab = 2 (tsawg dua 3 mph)
Kev thauj mus los sab nraum zoov uas siv zog tsav = 3 (tsawg dua 3 mph)
Cov hauv qab no yog ib daim ntawv yooj yim dua ntawm qhov sib npaug no rau lub tsheb laij teb 4-caster nrog 2 lub thoob ntiaj teb thiab 2 lub kev taw qhia, nrog rau qhov hnyav sib npaug ntawm txhua lub log nyob rau hauv cov xwm txheej kev thauj mus los hauv tsev:
C = Lub peev xwm thauj khoom xav tau ntawm cov casters
L = Qhov siab tshaj plaws ntawm lub trolley
W = Qhov hnyav ntawm lub laub
Piv txwv li, xav txog lub laub 300 phaus nrog 1,800 phaus thauj khoom rau nws. Qhov no yuav yog 2,100 lbs. faib los ntawm 3. Rau qhov thauj khoom no, txhua tus neeg tsav tsheb yuav tsum txhawb nqa / raug ntsuas rau 700 lbs. lossis ntau dua.
Yuav tsum tau soj ntsuam lwm yam kom paub meej tias lub caster twg xav tau rau daim ntawv thov, xws li: caster configuration, ambient temperature, duty cycle, tread material, thiab speed (log nrog ball bearings yuav muaj peev xwm txo qis ntawm qhov ceev tshaj 3 mph).
Ib yam li niaj zaus, peb cov kws tshwj xeeb daws teeb meem tuaj yeem tham txog koj daim ntawv thov kom paub tseeb tias siv lub caster kom raug, vim tias cov casters tsis yog tsuas yog lub log xwb.
Qhov thib peb, qhov kub ntawm qhov chaw uas nws siv yog dab tsi? Cov casters puas siv sab hauv tsev lossis sab nraum zoov? Thaum siv tiag tiag, ob qho tib si kub thiab qis yuav cuam tshuam rau kev ua haujlwm ntawm lub caster rau qee qhov.
Qhov thib plaub, cov xwm txheej thiab ib puag ncig tshwj xeeb uas koj cov log tsheb yuav raug siv yog dab tsi? Puas muaj cov khib nyiab? Puas muaj dej noo lossis cov tshuaj lom neeg? Puas yog lub hnub yuav ci ntsa iab tas li rau koj cov log tsheb? Puas yog hluav taws xob static yuav coj mus rau cov log tsheb thiab ua puas rau cov khoom muaj nqis?
Tag nrho cov lus nug no thiab ntau ntxiv yuav tsum tau nkag mus rau hauv cov txheej txheem txiav txim siab.
Yog tias koj muaj lus nug ntxiv txog kev xaiv tus caster, thov hu rau peb tus kheej.
