I-Tungsten Yesiliva
Imininingwane Yomkhiqizo
Amathegi Omkhiqizo
I-Ningbo De-Shin inikeza uhla oluphelele lwe-tungsten yesiliva yezinkambu ezahlukene zokusetshenziswa kwezimboni. Ithatha inqubo ethuthukisiwe yokungena nge-vacuum futhi yonke imikhiqizo ihlangabezana nenqubo ye-GB/T8320-2003, ASTM B631.
Inqubo yokukhiqiza:ingxube yempuphu –> ukucindezela –> ukuthulula –> ukungena kwe-vacuum –> imishini –> i-QC. Yonke le nqubo yokukhiqiza ilawulwa ngokuqinile yi-QC ukuqinisekisa ukusebenza kwekhwalithi ephezulu.
Izinzuzo:
1. Ukushisa okuphezulu kukagesi.
2. Ukushisa okuphezulu.
3. Ubuningi obukhulu obunokwakheka okulinganayo kwezinto ezincane.
Izicelo:
1. Ama-circuit breaker.
2. Iziphuli zokuvuza komhlaba.
3. Ama-circuit breaker amancane.
4. i-electrode yokushisela ukumelana.
5. umphini wokumelana nokuguguleka
Usayizi wesitoko:
Induku yesiliva ye-tungsten: ububanzi≥0.5mm, ngokuvamile 1-60mm; ubude≤300mm, ngokuvamile 100, 175, 200, 300mm.
Ibha yesikwele se-tungsten yesiliva: ubukhulu≥1.0mm, ngokuvamile 1-40mm; ubude nobubanzi≤400mm, ngokuvamile 100*200, 200*300, 200*400mm.
