Cov cuab yeej tswj lub cev muaj zog tau sib tw hnyav hauv kev siv marine thiab offshore. Lub cev muaj zog rau cov nkoj, cov chaw tawm ntug dej hiav txwv thiab cov chaw nres nkoj feem ntau ua haujlwm nyob rau hauv cov xwm txheej ntawm cov av noo, ntsev pos huab, kev co, tsis muaj zog txaus thiab txwv qhov chaw teeb tsa. Vim tias cov xwm txheej no, kev pib muaj kev vam meej, kev ua haujlwm ruaj khov thiab kev tiv thaiv lub cev muaj zog yog qhov tsim nyog heev.
VFDs thiabsoft pibyog ob txoj kev tswj lub cev muaj zog rau cov khoom siv xws li twj tso kua mis, kiv cua, compressors, ballast twj thiab twj tso kua dej txias. Feem ntau aVFDyog siv yog tias koj xav tau kev tswj ceev thiab kev txuag hluav taws xob. Asoft starteryog siv yog tias koj xav kom txo qis qhov pib tam sim no thiab txhua yam cuam tshuam nkaus xwb.
1. Lub cev muaj zog pib kev sib tw hauv Marine thiab Offshore Systems
Cov motors loj tuaj yeem muaj qhov cuam tshuam loj heev thaum pib ncaj qha. Qhov no tuaj yeem tsim hluav taws xob poob qis, cuam tshuam lub zog hluav taws xob thiab ua rau muaj kev ntxhov siab ntawm cov tshuab hluav taws xob, txuas, twj thiab lwm yam khoom siv tsav.
Cov kev cov nyom no tuaj yeem muaj teeb meem ntau dua nyob rau hauv marine thiab offshore cov xwm txheej uas lub zog hluav taws xob yuav muaj kev cuam tshuam ntau dua thiab cov cuab yeej siv feem ntau nyuaj kho. Yog li ntawd, kev tswj lub cev muaj zog pib yog ib txoj hauv kev tseem ceeb los txhim kho kev ntseeg siab thiab tiv thaiv kev hnav tsis tsim nyog.
2. Thaum siv VFD
A VFDtso cai rau kev pib du thiab hloov pauv ceev tswj. Nws yog qhov tsim nyog rau cov ntawv thov uas lub cev muaj zog yuav tsum tau yoog raws li qhov xav tau ntawm kev ua haujlwm xws li kev tswj ntws, tswj siab lossis lub zog- txuag kev ua haujlwm.
RENLE RNHV series nruab nrab voltageVFDyog tsim nyog rau kiv cua, twj tso kua mis thiab compressor. Nws txhawb nruab nrab voltage system zoo li 6kV thiab 10kV. Nws pab txo qis kev siv hluav taws xob tsis zoo los ntawm kev hloov kho lub cev muaj zog, txhim kho kev khiav thiab kev tswj xyuas siab, thiab ua kom muaj kev ruaj ntseg zoo dua.
RNHV series kuj muaj tsawg voltage caij los ntawm, ya pib, torque limiting, unit bypass thiab tej thaj chaw deb xyuas functions. Cov khoom zoo no tsim nyog rau kev lag luam thiab kev siv sab nrauv uas xav tau kev ntseeg tau zoo dua.
Rau cov motors uas khiav ntawm qhov ceev tsis tu ncua yuav tsum tau pib smoother, asoft starteryog ib txoj kev daws teeb meem. Tab sis es tsis txhob muab tag nrho cov voltage tam sim ntawd, nws maj mam nce lub cev muaj zog voltage thoob plaws qhov pib. Qhov no txo qhov pib tam sim no thiab poob siab rau lub tshuab.
RENLE RNMV kab nruab nrab voltage khoom- xeevsoft startersyog tsim nyog rau nruab nrab voltage squirrel-cage motors. Nws muaj voltage ramp pib thiab tam sim no limiting pib txo cov hluav taws xob cov nyhuv thiab txhua yam hnav ntawm lub cev muaj zog oob khab.
RNMV series tseem muaj kev tiv thaiv kev ua haujlwm xws li overload, overcurrent, undervoltage, theem poob, khw, overheat thiab ntev -pib- lub sij hawm tiv thaiv. Nws yog qhov zoo rau cov twj tso kua mis, compressors, conveyors thiab lwm yam kev siv lub cev muaj zog ruaj khov nyob rau hauv maritime thiab offshore systems.
4. Yuav ua li cas xaiv ntawm ib tug VFD thiab ib tug Soft Starter
Kev xaiv ntawm aVFDthiab asoft startertsis yog tsuas yog hais txog cov khoom lag luam, tab sis kuj hais txog yuav ua li cas lub cev muaj zog hauv kev ua haujlwm tiag tiag. Rau kev siv marine thiab offshore, cov neeg siv yuav tsum xav txog seb cov cuab yeej xav tau kev tswj ceev, txuag hluav taws xob, pib ua haujlwm zoo, lossis tsis tu ncua - ua haujlwm ceev.
Xaiv raws li kev ua haujlwm yuav tsum tau ua
Qhov kev xaiv ntawm aVFDthiab asoft starternyob ntawm qhov kev xav tau ntawm cov khoom siv.
VFDs rau kev tswj ceev thiab txuag hluav taws xob
VFDsyog qhov zoo tagnrho rau cov khoom siv uas yuav tsum tau tswj kev ceev, txuag hluav taws xob, lossis kev hloov pauv ntawm kev khiav thiab siab.
Soft Starters rau tas li -Speed Operations
Mos pibyog kev lag luam ntau dua thiab siv tau thaum cov khoom siv tsuas yog xav tau kev pib du thiab tom qab ntawd khiav ntawm qhov ceev tsis tu ncua. Hauv kev siv marine thiab offshore,VFDsthiabsoft starterskuj tuaj yeem siv ua ke kom sib npaug ntawm kev ua haujlwm, tus nqi thiab kev ntseeg tau.
