Hvac duct machine common fault analysis and processing:
Fault 1: Hvac duct machine Chong small mouth does not lift the knife
Analysis: It is possible that the electromagnetic valve is blocked by debris
Processing: Clean up the machine
Fault 2: Hvac duct machine
punching die and cutting knife can not move
Analysis: 1, may be the electrical box control hydraulic solenoid valve connection line disconnection;
2, may be damaged in the middle of the electrical box relay;
3, the touch screen automatically processed page does not show red or stuck solenoid valve.
Handling: Check the machine's electrical circuit or equipment is damaged, timely replacement and repair.
Failure 3: Hvac duct machine after the start of production sheet size instability or sheet only go non-stop
Analysis: 1, the lower right corner of the touch screen encoder status switch refers to the effective position;
2, one end of the measuring wheel mounted encoder loose slippery;
3, the encoder is damaged or the signal line is disconnected.
Treatment: Check the encoder and signal lines to see if there is deviation or damage, timely repair.
Fault 4: Hvac duct machine touch screen display hydraulic overload alarm and flashing
Analysis: 1, the hydraulic system pressure is too high;
2, the oil pump damage caused by thermal relay trip.
Handling: Disassemble the electrical cover, manual reset thermal relay.
Fault 5: Hvac duct machine touch screen display system emergency stop and servo alarm and flashing
Analysis: touch screen next to the emergency button is not loose.
Remedy: Release the emergency button next to the touch screen.
Failure 6: Hvac duct machine products produced cracks
Analysis: may be unqualified product raw materials or production process problems.
Treatment: Check the raw materials are qualified and operator negligence.
The above is that we have summarized for you some of the hvac duct machine in the production of common faults and their analysis and processing, in case of major problems, please contact the Hvac duct machine manufacturers in a timely manner.
