Troubleshooting method for high frequency induction hardening machine tools
Njira yothetsera mavuto zida zamakina owumitsa ma frequency induction
Chida chowumitsa makina owonjezera pafupipafupi:
1. Magetsi a gridi ndi okwera kwambiri (nthawi zambiri, magetsi a mafakitale ali pakati pa 360-420V).
2. Bolodi la dera la zida zowonongeka (Zener diode iyenera kusinthidwa).
Mavuto pakuthamanga kwa hydraulic kwa zida zamakina owumitsa ma frequency apamwamba:
1. The water pump pressure is not enough (the shaft wears caused by the pump working for a long time).
2. Kuyeza kuthamanga kwa madzi kwasweka.
Mavuto pakutentha kwamadzi kwa zida zamakina owumitsa ma frequency apamwamba kwambiri:
1. Kutentha kwa madzi ndikokwera kwambiri (nthawi zambiri kuyika kutentha kwa madigiri 45).
2. Chitoliro chamadzi ozizira chatsekedwa.
Kutayika kwa gawo la makina owumitsa ma frequency apamwamba:
1. Mzere wolowera wa magawo atatu wachoka.
2. Kupanda gawo chitetezo dera bolodi kuonongeka.
Tiyenera kufufuza zomwe zimayambitsa kulephera kosiyanasiyana ndikuthetsa mavuto kuti tikonze zida munthawi yake popanda kuchedwetsa ntchito.
