Ib Theem VFD Tsav Cov Ntsiab Cai

Txawm hais tias muaj ntau yam cuam tshuam nrog kev sib txawv zaus tsav (VFD), cov hauv qab no yog qhov tseem ceeb tshaj plaws.

Nruam khiav tam sim no ntsuas

Qhov no yog qhov siab tshaj plaws RMC tam sim no qhov sib txawv zaus tsav tuaj yeem ua haujlwm zoo nyob rau hauv txhua qhov kev ua haujlwm ntawm qhov kub thiab txias (feem ntau yog 40 [degrees] C). Lub cev muaj zog pob load sine yoj tam sim no yuav tsum sib npaug los yog tsawg dua qhov ntsuas no.

Overload tam sim no ntsuas

Qhov no yog lub sijhawm hloov pauv / qhov ntsuas tam sim no uas yog qhov siab tshaj plaws tam sim no qhov hloov pauv zaus tsav tuaj yeem tsim rau lub sijhawm teem sijhawm. Cov kev ntsuam xyuas raug yog 110% txog 150% overcurrent rau 1 min, nyob ntawm cov chaw tsim khoom. Kev ntsuas tam sim no siab dua tuaj yeem tau txais los ntawm kev saib xyuas qhov hloov pauv zaus tsav. Qhov kev ntsuas no tseem ceeb heev thaum sizing qhov sib txawv zaus tsav rau cov tam sim no xav tau los ntawm lub cev muaj zog rau kev tawg-tawm torque.

Kab hluav taws xob

Raws li nrog rau txhua lub cev muaj zog maub los, kev khiav hauj lwm voltage yuav tsum tau teev tseg. Qhov sib txawv zaus tsav tau tsim los ua haujlwm ntawm qee qhov hluav taws xob nominal xws li 240VAC lossis 480VAC, nrog rau qhov muaj peev xwm hloov pauv ntawm qhov ntxiv lossis rho tawm 10%. Feem ntau cov pib lub cev muaj zog yuav ua haujlwm dhau qhov kev hloov pauv no 10%, tab sis qhov sib txawv ntawm cov tsav tsheb yuav tsis thiab yuav mus rau hauv kev tiv thaiv. Kev kaw qhov hluav taws xob nyeem ntawm kab hluav taws xob sib txawv yog pom zoo rau txhua daim ntawv thov.

7 Cov txiaj ntsig ntawm Kev Siv Cov Tsav Tsheb Hloov Pauv (VFDs) los tswj koj lub crane lossis hoist

Kev kho kom nrawm dua:Nrog VFD tswj, koj muaj qhov yooj yim xaiv los ntawm ntau qhov nrawm, tso cai rau koj los kho koj lub hoist tswj kom phim cov kev cai tshwj xeeb ntawm koj daim ntawv thov. Qhov no versatility enables koj mus optimize qhov ceev rau txawv lifting hauj lwm thiab load tej yam kev mob, pab txhawb efficiency thiab productivity.

Txhim kho load tswj:Tso lub load uas siv lub hoist ib leeg tuaj yeem ua rau kev poob siab lossis kev sib tw. Txawm li cas los xij, nrog VFD, koj tuaj yeem ua tiav kev ua haujlwm zoo los ntawm kev maj mam ua kom lub nra hnyav. Qhov sib txawv zaus tsav ua kom tswj tau qhov nrawm thiab nrawm, txo qis cov viav vias thaum taug kev. Qhov kev tswj xyuas qhov hnyav no txo qhov kev pheej hmoo ntawm kev sib tsoo thiab ua kom muaj kev nyab xeeb ua haujlwm.

Lub luag haujlwm cycles:VFDs tuaj yeem ua tau raws li kev sib tw nrog lub braking resistor raws li lub luag haujlwm ntawm lub voj voog ntawm cov lus tsa suab. Qhov no tso cai rau kev txhim khu kev qha thiab tsis muaj kev cuam tshuam, txawm tias nyob rau hauv daim ntawv thov ua haujlwm siab. Tsis tas li ntawd, cov khoom siv rov ua dua tshiab uas tsis nyob ntawm lub luag haujlwm lub voj voog tuaj yeem siv tau, ntxiv dag zog rau kev ua haujlwm. Los ntawm kev ua kom muaj peev xwm ua haujlwm siab tshaj plaws, VFDs nce kev tsim khoom thiab txo qis qis qis.

Kev ua tau zoo:Ib qho txiaj ntsig tseem ceeb ntawm VFDs yog lawv lub peev xwm txuag hluav taws xob. Tsis zoo li cov contactors thiab soft-starters, VFDs tsuas yog siv lub zog xav tau, ua rau lub zog ua haujlwm tau zoo. Los ntawm kev ua kom lub cev muaj zog ceev thiab txo qis kev siv hluav taws xob tsis tsim nyog, VFDs pab txhawb rau kev txuag nqi thiab kev ruaj khov. Qhov tseeb, kev siv VFDs hauv koj lub crane lossis hoist haujlwm tuaj yeem ua rau muaj kev txuag hluav taws xob mus sij hawm ntev.

Nce lub neej hoist:Qee qhov sib txawv zaus tsav muab thermal overload thiab overcurrent tiv thaiv rau lub hoist motor, ncua nws lifespan. Tsis tas li ntawd, VFDs siv txoj kev ramp-down-to-stop braking es tsis txhob cia siab rau ntawm nkawm khau. Lub brake feem ntau yog siv rau qhov chaw nres tsheb thiab thaum muaj xwm txheej ceev, uas txo qhov hnav thiab tsim kua muag thiab ncua lub neej ntawm lub nres nres. Los ntawm kev ua kom lub neej ntev ntawm cov khoom tseem ceeb, VFDs txo cov nqi kho thiab txhim kho cov cuab yeej kev ntseeg siab.

Regenerative zog:Lub cev muaj zog generates regenerative zog thaum decelerating los yog txo ib tug hoist. Lub zog no tuaj yeem siv tau thiab hloov mus rau hauv cov cua sov siv lub braking resistor los yog redirected rov qab mus rau lub hwj chim qhov chaw, ua rau lub zog txuag. Ac regenerative tsav tau zoo rov faib lub zog no, tiv thaiv cov khib nyiab uas tshwm sim thaum nws hloov mus rau cua sov nrog lub braking resistor. Los ntawm kev siv zog rov tsim dua tshiab, VFDs txhawb kev ruaj khov thiab txo cov nqi ua haujlwm.

Digital Diagnostics:VFDs muaj peev xwm kuaj xyuas qib siab, ua kom yooj yim txij nkawm thiab daws teeb meem. Ntxiv rau, koj tuaj yeem saib xyuas thiab txheeb xyuas qhov ua tau zoo ntawm koj lub hoist lossis crane. Cov peev xwm kuaj mob no tuaj yeem nkag mus rau ntawm tus tsav nws tus kheej lossis nyob deb, tso cai rau kev txheeb xyuas sai thiab daws teeb meem ntawm txhua qhov teeb meem. Koj tuaj yeem txo lub sijhawm poob qis, txhim kho cov sijhawm tu, thiab ua kom pom kev ua haujlwm zoo los ntawm kev siv cov kev kuaj mob digital.

Kev Siv Hluav Taws Xob ntawm Ib Theem VFD Drive

Ib theem VFD tsav yog siv rau kev siv hluav taws xob tsawg uas feem ntau xav tau tsawg dua ib lub zog.Qee qhov kev siv rau ib theem VFD tsav yog:

Qhov txawv ntawm Ib Theem VFD thiab Peb Theem VFD

Variable zaus tsav uas peb feem ntau tham txog feem ntau yog hais txog qhov tsawg-voltage VFD, thiab low-voltage VFD tuaj yeem muab faib ua ib theem VFD thiab peb theem VFD los ntawm kev xav ntawm lub hwj chim mov voltage.

Qhov sib txawv loj tshaj plaws ntawm ib theem VFD thiab peb theem VFD yog lub zog ntawm ib theem VFD yog muaj nyob ntawm cov hlau nyob thiab cov hlau nruab nrab nrog qhov hluav taws xob ntawm 220V. Tsuas muaj ib txoj hlua nyob xwb, thiaj li hu ua ib theem. Fais fab mov ntawm peb theem VFD muaj peb nyob ntawm tej, yog li nws hu ua peb theem VFD, nrog rau peb theem fais fab input VFD.

Tsis tas li ntawd, cov zis voltage ntawm ib theem VFD tuaj yeem muab faib ua ib theem tso zis thiab peb theem tso zis. Peb theem tso zis ntawm no yuav tsis tshaj lub hwj chim mov voltage. Yog tias ib theem tawm tswv yim yog 220V, peb theem cov zis kuj yuav yog 220v, uas txawv ntawm cov zis ntawm peb theem VFD. Kev sib raug zoo, kev sib txuas hom ntawm lawv cov motors kuj txawv. Yog tias qhov kev sib txuas tsis sib haum nrog qhov voltage, lub cev muaj zog tsis muaj zog.

Ib theem kev tawm tswv yim txhais tau hais tias tsuas muaj ob kab rau cov khoom siv hluav taws xob (ib kab nruab nrab thiab ib kab nyob), theem voltage ntawm input voltage yog 220V. Peb theem input txhais tau hais tias muaj peb-theem input xov hlau (peb-theem peb-xaim) los yog plaub-theem input xov hlau (peb-theem plaub-xaim), feem ntau, peb-theem plaub-xaim yog ntau. Peb lub tswv yim nyob ntawm cov xov hlau thiab ib lub xov hlau nruab nrab, theem hluav taws xob nruab nrab ntawm txhua lub xov hlau nyob thiab cov xaim nruab nrab yog 220V, theem voltage ntawm txhua ob txoj hlua nyob yog 380V.

Thaum lub hwj chim zoo ib yam, tam sim no ntawm ib theem fais fab mov yog sib npaug rau lub zog / 220V. Piv txwv tias lub zog yog 1000 watt, ces tam sim no yog 4.54A. Qhov tam sim no ntawm txhua qhov nyob ntawm peb theem fais fab mov yog sib npaug rau ib feem peb ntawm tag nrho cov tam sim no, uas yog 4.54 / 3=1.5A, yog li nws muaj qhov yuav tsum tau qis dua rau cov xaim, thiab cov xaim nyias tuaj yeem siv tau. Nws yuav tsum raug pom tias peb theem fais fab mov feem ntau muaj nyob rau hauv kev lag luam kev lag luam, feem ntau cov tsev neeg siv tsuas yog ib theem fais fab mov (ib tug nyob hlau, ib tug nruab nrab hlau thiab ib lub ntiaj teb hlau), VFD nrog peb theem fais fab mov siv tsis tau. . Ib theem fais fab mov VFD tuaj yeem siv rau hauv peb-theem plaub-xaim fais fab mov (txuas mus rau ib lub xaim nyob thiab ib qho nruab nrab hlau).
