Xyuas kom tseeb tias VFD, spindle lub cev muaj zog, thiab CNC tshuab txuas nrog rau cov xaim hauv av uas tsis muaj zog (<0.1 Ω), sim siv lub tshuab multimeter.

Siv 4-xov hlau thaiv thaiv (U, V, W, thiab hauv av) rau kev sib txuas ntawm lub cev muaj zog thiab tiv thaiv cov kab hluav taws xob tiv thaiv rau lub davhlau ya nyob twg kom txo qis EMI.

Txoj kev fais fab thiab tswj cov kab hluav taws xob sib cais kom tsis txhob cuam tshuam los ntawm cov kab hluav taws xob siab.

Tsis tu ncua soj ntsuam kiv cua, Terminals, thiab Connectors

Faulty cua txias kiv cua, xoob terminals, los yog corroded connectors yuav ua rau overheating (E.oH), theem poob (E.PLo, E.PL1), los yog faults txog fais fab tuag (E.Lu).

Kev ua

Xyuas cov cua txias VFD cov kiv cua kom ua haujlwm kom raug thiab ntxuav lossis hloov yog tias txhaws lossis puas. Rau cov dej-txias spindles, tshuaj xyuas cov kav dej txias thiab cov twj tso kua mis rau cov dej xau los yog txhaws.

Tshawb xyuas cov tswv yim (R, S, T) thiab cov zis (U, V, W) terminals rau looseness, corrosion, lossis puas siv lub hau ntswj kom nruj thiab multimeter los xyuas qhov txuas ntxiv.

Tshawb xyuas cov khoom sib txuas (piv txwv li, FWD, REV, DCM) rau kev ruaj ntseg kev sib txuas thiab kuaj cov teeb liab kev ncaj ncees nrog lub tshuab multimeter (piv txwv li, 24V rau logic signals).

Tsis txhob nrawm nrawm / qeeb qeeb

Kev ua kom nrawm nrawm lossis qeeb qeeb tuaj yeem ua rau overcurrent (E.oc, E.oCA) lossis overvoltage (E.ou) faults vim tam sim no lossis voltage spikes.

Kev ua

Teem kom ceev ceev ceev (PD014) thiab deceleration (PD015) lub sij hawm, feem ntau 5-10 vib nas this, tso cai rau kev hloov ceev.

Rau high-inertia spindles, nruab ib qho kev tiv thaiv sab nraud los tswj kev rov tsim hluav taws xob thaum lub sij hawm deceleration.

Saib xyuas machining tsis (piv txwv li, txiav qhov tob, pub tus nqi) kom tsis txhob muaj kev hloov pauv tam sim ntawd uas nyuaj rau VFD.

Ua Kev Kho Mob Tag Nrho Txhua 6 Lub Hlis

Kev saib xyuas kev nyab xeeb kom ntes tau cov teeb meem muaj peev xwm ua ntej lawv ua txhaum, ua kom muaj kev ntseeg tau ntev.

Kev ua

Ua ib qho kev tshuaj xyuas tag nrho, suav nrog kev xaim, hauv av, cua txias, thiab lub cev muaj zog (piv txwv li, winding tsis kam, rwb thaiv tsev> 1 MΩ).

Ntxuav cov VFD, ntxaiv, thiab cov cuab yeej tuav kom huv si, kuaj xyuas cov plua plav, cov dej txias, lossis hnav.

Txheeb xyuas tag nrho VFD tsis txwv (piv txwv li, PD008, PD141, PD142, PD144) phim cov ntxaiv qhov tshwj xeeb thiab rov qab mus rau lub Hoobkas ua ntej (PD013 = 08) yog tias pom qhov tsis sib xws.

Siv cov cuab yeej kuaj mob xws li thermal imager (los kuaj xyuas cov chaw kub), vibration analyzer (rau cov kabmob coj), thiab megohmmeter (rau kev ntsuas rwb thaiv tsev).

Thaum twg Hu rau Zhong Hua Jiang Support

Qee qhov kev ua txhaum, tshwj xeeb yog cov koom nrog VFD sab hauv, xav tau cov kws tshaj lij kom tsis txhob muaj kev puas tsuaj ntxiv lossis tsis lees paub. Hu rau lub chaw pabcuam Zhong Hua Jiang tau tso cai hauv cov xwm txheej hauv qab no:

Persistent Complex Faults

Yog tias qhov tsis zoo xws li E.HHC (kev sib txuas lus sab hauv yuam kev), E.FoP (lub hwj chim raj tiv thaiv), lossis E.GFF (luv luv Circuit Court rau hauv av) txuas ntxiv tom qab kev daws teeb meem yooj yim (piv txwv li, kuaj cov xaim, hauv av, lossis lub cev muaj zog), qhov teeb meem yuav muaj cov khoom siv sab hauv xws li lub rooj tsav xwm tswj lossis IGBT modules.

Tsis paub lossis rov ua txhaum

Yog tias cov lej txhaum cai tsis paub, tsis tau teev nyob rau hauv phau ntawv qhia, lossis rov ua dua txawm tias muaj kev kho, kev kuaj mob yuav tsum tau txheeb xyuas cov teeb meem hauv qab no.

Internal Component Suspicions

Kev ua txhaum uas qhia txog kev puas tsuaj rau cov capacitors, transistors, lossis firmware xav tau cov cuab yeej tshwj xeeb los kho.

Cov kauj ruam ua ntej hu rau kev txhawb nqa

Sau cov cai txhaum cai (piv txwv li, E.HHC), cov xwm txheej hauv qab uas nws tshwm sim (xws li, thaum pib, kev ua haujlwm siab), thiab txhua qhov kev daws teeb meem tau sim.

Nco ntsoov VFD tus qauv naj npawb, spindle specifications, thiab parameter nqis los muab cov kws kho mob cov ncauj lus kom ntxaws.

Siv cov duab lossis cov yeeb yaj kiab ntawm VFD zaub thiab teeb tsa yog tias ua tau, vim tias cov no tuaj yeem pab kuaj xyuas thaj chaw deb.

Hu rau tus neeg muag khoom lossis cov chaw tsim khoom ntawm lawv txoj kev txhawb nqa channel (xws li email, xov tooj, lossis lub vev xaib) rau kev taw qhia lossis npaj kev pabcuam.

Xaus

Zhong Hua Jiang VFDs yog tsim los nrog cov txheej txheem tiv thaiv qib siab uas tsim cov lej txhaum cai rau cov neeg ua haujlwm ceeb toom rau cov teeb meem xws li overcurrent (E.oc), overvoltage (E.ou), overheating (E.oH), lossis sab hauv yuam kev (E.HHC), tiv thaiv CNC tshuab los ntawm kev puas tsuaj. Los ntawm kev nkag siab txog cov cai no thiab ua raws li kev nyab xeeb, kev daws teeb meem cov kauj ruam-xws li kuaj xyuas cov xaim, kho qhov tsis sib xws, lossis daws teeb meem kev siv tshuab-cov neeg ua haujlwm tuaj yeem rov ua haujlwm sai thiab tiv thaiv kev cuam tshuam tsis zoo. Kev tiv thaiv kev tiv thaiv, suav nrog kev ua kom VFD huv si thiab qhuav, ua kom cov av tsim nyog, tshuaj xyuas cov khoom tsis tu ncua, zam kev hloov pauv sai, thiab ua haujlwm zoo txhua txhua 6 lub hlis, yog qhov tseem ceeb ntawm kev txo qhov ua yuam kev thiab txuas ntxiv cov cuab yeej siv. Rau qhov nyuaj lossis tsis ua haujlwm tsis tu ncua, hu rau Zhong Hua Jiang kev txhawb nqa nrog cov ntaub ntawv qhia txog kev ua txhaum kom paub meej. Los ntawm kev sib koom ua ke nrog kev saib xyuas zoo nrog kev paub daws teeb meem, koj tuaj yeem tswj hwm qhov tseeb, ua haujlwm tau zoo, thiab kev ntseeg siab ntawm koj cov haujlwm CNC, kom ntseeg tau cov txiaj ntsig zoo ntawm machining thiab kev ua haujlwm ntev.
