Tlhokomelo e felletseng e hlahloba mathata a ka bang teng pele a baka liphoso, ho netefatsa ts'epo ea nako e telele.

Liketso

Etsa tlhahlobo e felletseng ea sistimi, ho kenyeletsoa likhoele, ho thella fatše, sistimi ea ho pholisa, le boemo ba makoloi (mohlala, ho hanyetsa maqhubu, ho kenya letsoho> 1 MΩ).

Hloekisa VFD, spindle, le litšepe tsa lithulusi ka botlalo, u lekola hore na ha ho na lerōle, masalla a pholiso, kapa moaparo.

Netefatsa liparamente tsohle tsa VFD (mohlala, PD008, PD141, PD142, PD144) li tsamaellana le lintlha tsa spindle 'me u lokisetse litlhophiso tsa feme (PD013=08) haeba ho se lumellane.

Sebelisa lisebelisoa tsa ho hlahloba tse kang sets'oants'o sa mocheso (ho bona libaka tse chesang), analyzer ea vibration (bakeng sa ho apara), le megohmmeter (bakeng sa tlhahlobo ea insulation).

Nako ea ho Kopana le Ts'ehetso ea Zhong Hua Jiang

Liphoso tse ling, haholo tse amang likarolo tsa VFD tsa kahare, li hloka boitseanape ba litsebi ho qoba ts'enyehelo e eketsehileng kapa litiisetso tsa lefeela. Ikopanye le setsi sa litšebeletso se lumelletsoeng sa Zhong Hua Jiang maemong a latelang:

Liphoso Tse Tsoelang Pele Tse Ratang

Haeba liphoso tse kang E.HHC (phoso ea puisano ea ka hare), E.FoP (thibela matla a tube), kapa E.GFF (nako e khutšoanyane ea potoloho ho ea fatše) e ntse e tsoela pele ka mor'a ho rarolla mathata (mohlala, ho hlahloba wiring, grounding, kapa motor insulation), taba e ka 'na ea akarelletsa likarolo tse ka hare tse kang boto ea taolo kapa li-module tsa IGBT.

Liphoso Tse sa Tsejoeng Kapa Tse Tsoang Khafetsa

Haeba li-fault code li sa tloaeleha, li sa thathamisoa bukeng, kapa li ipheta ho sa tsotellehe litokiso, tlhahlobo ea litsebi e ea hlokahala ho tseba mathata a teng.

Lipelaelo tsa Karolo e ka Hare

Liphoso tse bontšang tšenyo e ka bang teng ho li-capacitor, transistors, kapa firmware li hloka lisebelisoa tse khethehileng bakeng sa ho lokisoa.

Mehato Pele o Kopana le Tšehetso

Ngola khoutu e nepahetseng hantle (mohlala, E.HHC), maemo ao e hlahileng tlas'a eona (mohlala, nakong ea ho qala, ts'ebetso ea lebelo le holimo), le mehato efe kapa efe e lekiloeng ea ho rarolla mathata.

Ela hloko nomoro ea mohlala ea VFD, litlhaloso tsa spindle, le litlhophiso tsa paramethara ho fa litsebi lintlha tse qaqileng.

Nka linepe kapa livideo tsa ponts'o ea VFD 'me u e sete ha ho khonahala, kaha tsena li ka thusa tlhahlobo e hole.

Ikopanye le mofani oa thepa kapa moetsi ka mocha oa bona oa tšehetso oa semmuso (mohlala, lengolo-tsoibila, mohala, kapa webosaete) bakeng sa tataiso kapa ho hlophisa litšebeletso.

Qetello

Li-VFD tsa Zhong Hua Jiang li entsoe ka lisebelisoa tsa ts'ireletso tse tsoetseng pele tse hlahisang likhoutu tsa phoso ho hlokomelisa basebetsi ka litaba tse kang overcurrent (E.oc), overvoltage (E.ou), overheating (E.oH), kapa liphoso tsa ka hare (E.HHC), tse sireletsang mechine ea CNC hore e se ke ea senyeha. Ka ho utloisisa likhoutu tsena le ho latela mehato e bolokehileng, e hlophisehileng ea ho rarolla mathata - joalo ka ho hlahloba lithapo, ho lokisa liparamente, kapa ho rarolla mathata a mochini - basebelisi ba ka khutlisetsa ts'ebetso e tloaelehileng kapele mme ba thibela litšitiso tse theko e boima. Thibelo e tsoelang pele, e kenyeletsang ho boloka VFD e hloekile ebile e omme, ho etsa bonnete ba hore motheo o nepahetseng, ho hlahloba likaroloana kamehla, ho qoba liphetoho tse potlakileng tsa lebelo, le ho etsa tlhokomelo e feletseng likhoeling tse ling le tse ling tse 6, ke senotlolo sa ho fokotsa liphoso le ho lelefatsa nako ea bophelo ea thepa. Bakeng sa liphoso tse rarahaneng kapa tse phehellang, ho ikopanya le tšehetso ea Zhong Hua Jiang ka lintlha tse qaqileng tsa liphoso ho netefatsa tharollo e sebetsang. Ka ho kopanya tlhokomelo e hlokolosi le ho rarolla mathata ka tsebo, o ka boloka ho nepahala, ho sebetsa hantle le ho ts'epahala ha ts'ebetso ea hau ea CNC, ho netefatsa liphetho tsa boleng bo holimo tsa mochini le ts'ebetso ea nako e telele ea sistimi.
