Amanyathelo okuthintela-njengokusekwa okufanelekileyo kwasekuqaleni, ukugcinwa rhoqo, kunye nokulawulwa kokusingqongileyo-ukunciphisa le miba kwaye uqinisekise ukusebenza okuthembekileyo. Soloko ujongana nencwadana yemigaqo ye-VFD yesikhokelo esikhethekileyo, sebenzisa izixhobo ezifanelekileyo zokuxilonga, kwaye ufune uncedo lobuchwephesha kwimiba entsonkothileyo ukugcina ukuchaneka nokusebenza kakuhle kwimisebenzi yakho yomatshini ye-CNC.

Ukuthintela iimpazamo ze-VFD zexesha elizayo

Ukuthintela iimpazamo kwi-Zhong Hua Jiang Ii-Variable Frequency Drives (VFDs) zisebenza kakhulu kunokujongana nokulungiswa, njengoko kunciphisa ixesha lokuphumla, ukunciphisa iindleko zokugcinwa, kunye nokuqinisekisa ukusebenza okuhambelanayo kwe-CNC (i-Computer Numerical Control). Ngokwamkela iinkqubo zolungiso olukhawulezileyo kunye nokwandisa indawo yokusebenza, unokunciphisa ngokubonakalayo ukubakho kweempazamo ezifana ne-overcurrent (E.oc), overvoltage (E.ou), okanye ukufudumeza (E.oH). La manyathelo agxininise ekugcineni imeko ye-VFD, ukuqinisekisa ukuseta umbane ngokufanelekileyo, kunye nokulawula iiparamitha zokusebenza ukukhusela zombini i-VFD kunye ne-spindle motor edibeneyo. Ngezantsi ngamanyathelo aphambili okuthintela ukugcina iZhong Hua Jiang VFD yakho isebenza kakuhle.

Gcina i-VFD yakho icocekile kwaye yomile

Uthuli, ukungcola, kunye nokufuma kunokuphazamisa inkqubo yokupholisa ye-VFD, kubangele iziphene zombane, okanye kukhokelela ekudlekeni, kubangele imiba efana nokufudumeza (E.oH) okanye iimpazamo zomhlaba (E.GFF).

Izenzo

Faka i-VFD kwindawo engenathuli, eyomileyo, ngokufanelekileyo kwindawo evaliweyo, i-IP-rated enclosure ukukhusela kwizinto ezingcolileyo.

Coca umphandle kunye namaphiko okupholisa eVFD (ukwenzela imifuziselo epholiswe ngumoya) qho ngenyanga usebenzisa umoya ocinezelweyo okanye ibrashi ethambileyo ukususa ukugcwala kothuli.

Khangela ukungena kokufuma, ngakumbi kwiindawo ezifumileyo, kwaye usebenzise iipakethi zejeli ye-silica okanye izinto zokukhupha amanzi xa kukho imfuneko.

Ukuqinisekisa ukubekwa komhlaba okukuko kunye nokuKhuselwa kweCable

Ukumisa ngokungafanelekanga okanye iintambo ezingakhuselekanga zinokubangela ukuphazamiseka kwe-electromagnetic interference (EMI), okukhokelela kwiimpazamo ezifana ne-E.HHC (impazamo yonxibelelwano lwangaphakathi) okanye ukuziphatha okungahambi kakuhle kwemoto.

Izenzo

Qinisekisa ukuba i-VFD, i-spindle motor, kunye nomatshini we-CNC uqhagamshelwe kwi-wire yomhlaba ozinikeleyo kunye nokuchasana okuphantsi (<0.1 Ω), ihlolwe ngokusebenzisa i-multimeter.

Sebenzisa iintambo zocingo ezi-4 ezikhuselekileyo (U, V, W, kunye nomhlaba) kuqhagamshelo lweemoto kunye neentambo zolawulo ezikhuselweyo kwiimpawu zetheminali ukunciphisa i-EMI.

Amandla omzila kunye neentambo zokulawula ngokwahlukeneyo ukuphepha ukuphazamiseka kwiintambo zamandla aphezulu.

Rhoqo ukuHlola iiFani, izikhululo, kunye neziqhagamshelo

Iifeni zokupholisa eziphosakeleyo, iitheminali ezikhululekile, okanye izixhumi ezidibeneyo zingakhokelela ekugqithiseni (E.oH), ukulahleka kwesigaba (E.PLo, E.PL1), okanye iimpazamo ezinxulumene namandla (E.Lu).

Izenzo

Jonga iifeni ze-VFD ezipholileyo ngomoya ukuze zisebenze ngokufanelekileyo kwaye zicoceke okanye zitshintshe ukuba zivaliwe okanye zonakele. Kwimibhobho yokupholisa epholiswe ngamanzi, jonga imibhobho yokupholisa kunye neempompo zokuvuza okanye ukuvaleka.

Hlola igalelo (R, S, T) kunye nemveliso (U, V, W) ii-terminals zokukhululeka, ukubola, okanye umonakalo usebenzisa i-screwdriver ukuqinisa kunye ne-multimeter ukujonga ukuqhubeka.

Hlola izihlanganisi zolawulo (umzekelo, i-FWD, i-REV, i-DCM) yoqhagamshelwano olukhuselekileyo kunye novavanyo lwembonakaliso yesignali nge-multimeter (umzekelo, i-24V yeempawu zengqiqo).

Kuphephe ukuKhawuleza okuKhawulezileyo / ukuBuyisa imijikelo

Ukukhawuleza okukhawulezileyo okanye ukusetwa kokunciphisa kunokubangela i-overcurrent (E.oc, E.oCA) okanye i-overvoltage (E.ou) iimpazamo ngenxa yangoku okanye i-voltage spikes.

Izenzo

Cwangcisa ukukhawuleza kwe-conservative acceleration (PD014) kunye ne-deceleration (PD015) amaxesha, ngokuqhelekileyo i-5-10 imizuzwana, ukuvumela utshintsho olukhawulezayo.

Kwii-spindles eziphezulu ze-inertia, faka i-resistor ye-braking yangaphandle ukulawula i-voltage yokuvuselela ngexesha lokunciphisa.

Ukubeka iliso kwiiparamitha zoomatshini (umzekelo, ubunzulu bokusika, umlinganiselo wesondlo) ukunqanda utshintsho olukhawulezileyo lomthwalo ocinezela i-VFD.

Yenza uLondolozo olupheleleyo rhoqo kwiinyanga ezi-6

Ulondolozo olubanzi luhlola ukubamba imiba enokubakho ngaphambi kokuba ibangele iimpazamo, ukuqinisekisa ukuthembeka kwexesha elide.

Izenzo

Ukuqhuba uhlolo olupheleleyo lwesixokelelwano, kuqukwa iingcingo, ukumisa phantsi, iinkqubo zokupholisa, kunye nemeko yemoto (umzekelo, ukuxhathisa ukujika, ukugquma > 1 MΩ).

Coca i-VFD, i-spindle, kunye nezibambi zezixhobo ngokucokisekileyo, ujonga uthuli, iintsalela zokupholisa, okanye ukunxiba.

Qinisekisa zonke iiparamitha ze-VFD (umzekelo, i-PD008, PD141, PD142, PD144) ifanise nemigaqo ye-spindle kwaye uphinde umisele ukungagqibeki kwasefektri (PD013=08) ukuba kukho ukungangqinelani kufunyenwe.

Sebenzisa izixhobo zokuxilonga ezifana ne-image ye-thermal (ukubona iindawo ezishushu), i-vibration analyzer (yokuthwala ukunxiba), kunye ne-megohmmeter (yovavanyo lokugquma).

Xa uQhagamshelana neZhong Hua Jiang Inkxaso

Ezinye iziphene, ngakumbi ezo zibandakanya amacandelo angaphakathi e-VFD, zifuna ubuchwephesha obuchwepheshile ukunqanda umonakalo ongakumbi okanye ukuphelisa iziqinisekiso. Qhagamshelana neziko lenkonzo eligunyazisiweyo laseZhong Hua Jiang kwezi meko zilandelayo:

Iimpazamo eziZingileyo eziNgxaki

Ukuba iziphene ezifana ne-E.HHC (impazamo yonxibelelwano lwangaphakathi), i-E.FoP (ukhuseleko lwetyhubhu yamandla), okanye i-E.GFF (isiphaluka esifutshane ukuya emhlabeni) iyaqhubeka emva kokucombulula iingxaki ezisisiseko (umzekelo, ukujonga i-wiring, i-grounding, okanye i-motor insulation), umba mhlawumbi ubandakanya amacandelo angaphakathi njengebhodi yokulawula okanye iimodyuli ze-IGBT.

Iimpazamo ezingaziwayo okanye eziqhubekayo

Ukuba iikhowudi zeempazamo aziqhelekanga, azidweliswanga kwincwadana yemigaqo, okanye ziphinde zenzeke ngaphandle kokulungiswa, ukuxilongwa kweengcali kuyafuneka ukuchonga imiba esisiseko.

Internal Component Izikrokro

Iimpazamo ezibonisa umonakalo onokwenzeka kwi-capacitors, transistors, okanye i-firmware ifuna izixhobo ezikhethekileyo zokulungiswa.

Amanyathelo phambi kokuQhagamshelana neNkxaso

Rekhoda eyona khowudi yempazamo (umzekelo, E.HHC), iimeko evele phantsi kwayo (umzekelo, ngexesha lokuqalisa, ukusebenza ngesantya esiphezulu), kunye nawo nawaphi na amanyathelo azamile okusombulula ingxaki.

Qaphela inombolo yemodeli ye-VFD, iinkcukacha ze-spindle, kunye noseto lweparamitha ukunika amagcisa ngolwazi oluneenkcukacha.

Thatha iifoto okanye iividiyo zomboniso weVFD kwaye usete ukuba kunokwenzeka, njengoko ezi zinokunceda ukuxilongwa kude.

Qhagamshelana nomthengisi okanye umenzi ngejelo labo elisemthethweni lenkxaso (umzekelo, i-imeyile, ifowuni, okanye iwebhusayithi) ukufumana isikhokelo okanye ukulungiselela inkonzo.

Ukuqukumbela

I-Zhong Hua Jiang VFDs zenziwe ngeenkqubo zokukhusela eziphuculweyo ezivelisa iikhowudi eziphosakeleyo zokulumkisa abaqhubi kwimiba efana ne-overcurrent (E.oc), i-overvoltage (E.ou), i-overheating (E.oH), okanye iimpazamo zangaphakathi (E.HHC), ukukhusela oomatshini be-CNC kumonakalo. Ngokuqonda ezi khowudi kunye nokulandela amanyathelo akhuselekileyo, acwangcisiweyo okusombulula ingxaki-njengokukhangela i-wiring, ukulungiswa kweeparameters, okanye ukujongana nemiba yomatshini-abaqhubi banokubuyisela ngokukhawuleza ukusebenza okuqhelekileyo kunye nokuthintela ukuphazamiseka kweendleko. Ukuthintela okusebenzayo, kubandakanywa nokugcina i-VFD icocekile kwaye yomile, ukuqinisekisa ukusekwa okufanelekileyo, ukuhlola amacandelo rhoqo, ukuphepha utshintsho olukhawulezayo, kunye nokwenza ukugcinwa okupheleleyo rhoqo kwiinyanga ze-6, ngundoqo ekunciphiseni iimpazamo kunye nokwandisa ixesha lokuphila kwezixhobo. Ngeempazamo ezinzima okanye eziqhubekayo, ukunxibelelana noZhong Hua Jiang ngenkxaso eneenkcukacha ezichanekileyo kuqinisekisa isisombululo esisebenzayo. Ngokudibanisa ugcino olunenkuthalo kunye nokusombulula ingxaki, unokugcina ukuchaneka, ukusebenza kakuhle, kunye nokuthembeka kwemisebenzi yakho ye-CNC, uqinisekisa iziphumo zomgangatho ophezulu womatshini kunye nokuqina kwenkqubo yexesha elide.
