Ngati manambala olakwika ndi osadziwika bwino, osalembedwa m'bukuli, kapena abwerezedwanso ngakhale atawongolera, kuyezetsa kwa akatswiri ndikofunikira kuti adziwe zomwe zimayambitsa.

Kukayikitsa kwachigawo chamkati

Zolakwika zomwe zikuwonetsa kuwonongeka kwa ma capacitor, transistors, kapena firmware zimafunikira zida zapadera kuti zikonzedwe.

Njira Musanalumikizane ndi Thandizo

Lembani zolakwika zenizeni (monga E.HHC), momwe zidawonekera (mwachitsanzo, poyambitsa, ntchito yothamanga kwambiri), ndi njira zilizonse zothetsera mavuto.

Dziwani nambala yachitsanzo ya VFD, mawonekedwe a spindle, ndi zoikamo kuti mupatse akatswiri chidziwitso chatsatanetsatane.

Tengani zithunzi kapena makanema owonetsera VFD ndikukhazikitsa ngati kuli kotheka, chifukwa izi zitha kuthandiza kuzindikira zakutali.

Lumikizanani ndi ogulitsa kapena opanga kudzera pa njira yawo yovomerezeka (monga imelo, foni, kapena tsamba la webusayiti) kuti mupeze malangizo kapena kukonza ntchito.

Mapeto

Zhong Hua Jiang VFDs amapangidwa ndi zida zodzitchinjiriza zotsogola zomwe zimapanga manambala olakwika kuti adziwitse ogwiritsa ntchito zinthu ngati overcurrent (E.oc), overvoltage (E.ou), overheating (E.oH), kapena zolakwika zamkati (E.HHC), kuteteza makina a CNC kuti asawonongeke. Pomvetsetsa zizindikirozi ndikutsatira njira zotetezeka, zowonongeka mwadongosolo-monga kuyang'ana mawaya, kusintha magawo, kapena kuthana ndi zovuta zamakina -othandizira amatha kubwezeretsa ntchito yanthawi zonse ndikupewa kusokoneza kwamtengo wapatali. Kupewa mwachangu, kuphatikizapo kusunga VFD yaukhondo ndi youma, kuonetsetsa kuti ili bwino, kuyang'ana zigawo zake nthawi zonse, kupewa kusintha kwachangu, ndi kukonza bwino miyezi isanu ndi umodzi iliyonse, ndikofunikira kuti muchepetse zolakwika ndikutalikitsa moyo wa zida. Pazolakwa zovuta kapena zopitilira, kulumikizana ndi chithandizo cha Zhong Hua Jiang ndi chidziwitso chatsatanetsatane kumatsimikizira kukonza bwino. Mwa kuphatikiza kukonza mwakhama ndi kuwongolera zovuta, mutha kusunga zolondola, zogwira mtima, komanso kudalirika kwa ntchito zanu za CNC, kuwonetsetsa kuti makina anu ali ndi zotsatira zapamwamba komanso kukhazikika kwadongosolo kwanthawi yayitali.
