1. Xaiv cov castor thiab cov log tsheb
Lub hom phiaj ntawm kev siv cov castor thiab cov log tsheb yog los txo kev siv zog thiab txhim kho kev ua haujlwm. Xaiv txoj cai muaj castor thiab lub log raws li daim ntawv thov txoj kev, cov xwm txheej thiab cov kev xav tau (kev yooj yim, kev txuag hluav taws xob, ua haujlwm ntev). Thov xav txog cov ntsiab lus hauv qab no: A. Load-bearing hnyav: (1) Load-bearing hnyav xam: T = (E + Z) / M×N:
T＝hnyav nqa los ntawm txhua tus caster E＝hnyav ntawm lub tsheb thauj khoom Z＝qhov hnyav ntawm mobile theem M＝zoo load-bearing kom muaj nuj nqis ntawm lub log
(Qhov tseem ceeb ntawm qhov tsis sib luag ntawm txoj haujlwm thiab qhov hnyav yuav tsum raug txiav txim siab) (2) Kev siv lub log muaj nuj nqi ntawm lub log (M) yog raws li qhia hauv daim duab hauv qab no:
E＝hnyav ntawm lub tsheb thauj khoom
Z＝qhov hnyav ntawm mobile theem M＝Kev ua haujlwm zoo ntawm cov kabmob ntawm lub log (qhov tseem ceeb ntawm qhov tsis sib xws ntawm txoj haujlwm thiab qhov hnyav yuav tsum raug txiav txim siab) (2) Cov kabmob muaj peev xwm ntawm lub log (M) yog raws li qhia hauv daim duab hauv qab no:
(3)Thaum xaiv lub peev xwm load-bearing, xam nws raws li lub peev xwm load-bearing ntawm lub caster ntawm qhov kev txhawb nqa siab tshaj plaws. Cov ntsiab lus txhawb nqa caster tau qhia hauv daim duab hauv qab no, nrog P2 yog qhov hnyav tshaj plaws txhawb nqa. B. Flexibility
(4)(1) muaj castor thiab lub log yuav tsum hloov tau, yooj yim thiab ruaj khov. Cov khoom sib hloov (caster rotation, log dov) yuav tsum tau ua los ntawm cov ntaub ntawv uas tsis tshua muaj kev sib txhuam coefficient lossis cov khoom siv sib dhos tom qab kev ua haujlwm tshwj xeeb (xws li pob bearings lossis quenching kho).
(5)(2) Qhov loj dua qhov eccentricity ntawm lub tripod, qhov hloov tau yooj yim dua, tab sis qhov hnyav load-bearing tau raug txo qis.
(6)(3) Qhov loj ntawm txoj kab uas hla ntawm lub log, qhov kev siv zog tsawg dua los thawb nws, thiab qhov zoo dua tuaj yeem tiv thaiv hauv av. Cov log loj tig qeeb dua cov me me, tsis tshua muaj cua sov thiab deform, thiab ruaj khov dua. Xaiv cov log nrog cov kab uas loj dua kom ntau li ntau tau nyob rau hauv cov xwm txheej uas qhov siab qhov siab tso cai.
(7)C. Tsiv ceev: Caster ceev yuav tsum tau: Nyob rau hauv ib txwm kub, nyob rau hauv ib tug ca hauv av, tsis pub tshaj 4KM / H, thiab nrog ib tug tej yam nqi ntawm so.
(8)D. Siv ib puag ncig: Thaum xaiv, cov khoom siv hauv av, cov teeb meem, cov khoom seem lossis qhov chaw tshwj xeeb (xws li cov ntaub ntawv hlau, qhov kub thiab txias, acidity thiab alkali, roj thiab tshuaj lom neeg kev coj ua, thiab qhov chaw uas yuav tsum tau muaj hluav taws xob tiv thaiv zoo li qub) yuav tsum tau txiav txim siab. industrial castor thiab lub log ua los ntawm cov ntaub ntawv tshwj xeeb yuav tsum raug xaiv los siv rau hauv qhov chaw tshwj xeeb.
(9)E. Kev ceev faj txog kev txhim kho: tiaj tus sab saum toj: lub installation nto yuav tsum tiaj tus, tawv thiab ncaj, thiab tsis xoob. Kev taw qhia: Ob lub log yuav tsum nyob rau tib qho kev taw qhia thiab sib npaug. Xov: Caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau ntsia kom tsis txhob xoob.
(10)F. Kev ua tau zoo ntawm cov ntaub ntawv log: Txais tos tuaj xyuas peb lub tuam txhab lossis thov cov ntaub ntawv teev npe.
Taw qhia rau kev ntsuas kev ua haujlwm ntawm kev lag luam castor thiab lub log
Cov khoom tsim nyog caster yuav tsum tau ua raws li kev ntsuas nruj thiab kev ua tau zoo ua ntej tawm hauv lub hoobkas. Cov hauv qab no yog ib qho kev qhia txog tsib hom kev xeem uas tam sim no siv los ntawm cov lag luam:
1. Kev ntsuas kev ua tau zoo thaum kuaj qhov kev ua tau zoo, lub caster yuav tsum tau muab khaws cia kom qhuav thiab huv. Muab lub caster tso rau ntawm ib lub phaj hlau insulated los ntawm hauv av, khaws lub log ntug nyob rau hauv kev sib cuag nrog cov hlau phaj, thiab thauj 5% mus rau 10% ntawm nws cov qauv load ntawm lub caster. Siv cov khoom siv hluav taws xob tiv thaiv hluav taws xob los ntsuas qhov ntsuas tus nqi ntawm cov caster thiab cov phaj hlau.
2. Impact test Nruab lub caster vertically rau hauv av xeem platform, kom ib tug 5kg tav su poob dawb do los ntawm ib qhov siab ntawm 200mm, tso cai rau ib tug 3 hli sib txawv los cuam tshuam lub log ntug ntawm lub caster. Yog tias muaj ob lub log, ob lub log yuav tsum cuam tshuam tib lub sijhawm.
3. Static load test Cov txheej txheem kev thauj khoom zoo li qub ntawm kev lag luam castor thiab lub log yog txhawm rau txhim kho kev lag luam castor thiab lub log ntawm kab rov tav thiab du steel test platform nrog screws, siv lub zog ntawm 800N raws li qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov castor thiab lub log rau 24 teev, tshem tawm lub zog rau 24 teev thiab xyuas cov xwm txheej ntawm cov castor thiab lub log. Tom qab qhov kev xeem, qhov deformation ntawm cov castor thiab lub log ntsuas tsis tshaj 3% ntawm lub log txoj kab uas hla, thiab dov, kev sib hloov nyob ib ncig ntawm lub axis los yog braking muaj nuj nqi ntawm lub industrial castor thiab lub log tom qab qhov kev xeem yog tsim nyog.
4. Reciprocating wear test The reciprocating wear test of industrial castor and wheels simulates qhov tseeb dov tej yam kev mob ntawm industrial castor thiab log nyob rau hauv niaj hnub siv. Nws tau muab faib ua ob hom: kev sim teeb meem thiab tsis muaj kev sim siab. Kev lag luam castor thiab lub log tau raug teeb tsa kom raug thiab muab tso rau ntawm qhov chaw sim. Txhua qhov kev xeem caster yog loaded nrog 300N, thiab qhov ntsuas zaus yog (6-8) zaug / min. Ib lub voj voog kev xeem suav nrog kev txav mus los ntawm 1M rau pem hauv ntej thiab 1M rov qab. Thaum lub sij hawm xeem, tsis muaj caster lossis lwm qhov chaw raug tso cai kom tshem tawm. Tom qab qhov kev xeem, txhua tus caster yuav tsum muaj peev xwm taug kev nws txoj haujlwm ib txwm muaj. Tom qab kev sim, lub dov, pivoting lossis braking ua haujlwm ntawm lub caster yuav tsum tsis txhob raug puas tsuaj.
5. Rolling kuj thiab rotation resistance test
Rau qhov kev xeem dov tsis kam, tus qauv yog los nruab peb lub tshuab castor thiab lub log ntawm lub hauv paus ruaj khov peb sab. Raws li cov qib sib txawv, qhov ntsuas qhov ntsuas ntawm 300/600/900N yog siv rau lub hauv paus, thiab kab rov tav traction yog siv los ua cov caster ntawm qhov kev sim platform txav ntawm qhov ceev ntawm 50mm / S rau 10S. Txij li cov kev sib txhuam quab yuam loj thiab muaj qhov ceev ntawm qhov pib ntawm lub caster dov, kab rov tav traction yog ntsuas tom qab 5S ntawm qhov kev xeem. Qhov loj me tsis tshaj 15% ntawm qhov kev xeem thauj khoom kom dhau.
Kev ntsuas kev sib hloov yog txhawm rau nruab ib lossis ntau qhov kev lag luam castor thiab lub log ntawm cov kab los yog lub voj voos ntsuas kom lawv cov kev taw qhia yog 90° mus rau txoj kev tsav tsheb. Raws li qib sib txawv, qhov ntsuas qhov ntsuas ntawm 100/200/300N yog siv rau txhua tus caster. Siv cov kab rov tav traction quab yuam kom lub caster ntawm qhov kev sim platform taug kev ntawm qhov nrawm ntawm 50mm / S thiab tig hauv 2S. Sau qhov siab tshaj plaws traction quab yuam uas ua rau lub caster tig. Yog tias nws tsis tshaj 20% ntawm qhov kev xeem thauj khoom, nws tsim nyog.
Nco tseg: Tsuas yog cov khoom lag luam uas tau dhau qhov kev ntsuam xyuas saum toj no thiab tsim nyog tuaj yeem txheeb xyuas tias cov khoom siv caster tsim nyog, uas tuaj yeem ua lub luag haujlwm ntau dua hauv ntau daim ntawv thov. Yog li ntawd, txhua tus neeg tsim khoom lag luam yuav tsum muab qhov tseem ceeb rau qhov txuas tom qab kev tsim khoom.
