Common Fault Diagnosis and Troubleshooting Guide for Graphitization Fur"&"naces
Graphitization furnaces have complex structures and operate under harsh conditions, inevitably encountering various problems during long-term use. The most recommended method is to directly scan the QR code on the touchscreen of our graphit"&"ization furnace with your mobile phone and follow the fault and maintenance instructions step by step to check. Below are the diagnostic approaches and troubleshooting methods for common faults.
Temperature Abnormalit"&"y
"&"| Phenomenon | Possible Causes | Troubleshooting Methods |
|---|---|---|
| Temperature Cannot Rise | Insufficient Power Supply/Sensor Drift/Insu"&"lation Layer Aging | Check power output/calibrate sensor/check insulation layer |
| Large temperature fluctuations | Inappropriate PID parameters/power grid fluctuations/loose sensor | Re-tune PID/Check power grid/Tighten sensor |
| Local overheating | Uneven temperature field/improper material placement/damaged heating element | Temperature field measurement by tem"&"perature measuring ring/adjust loading/check heating element |
Vacuum Abnormality
| Phenomenon | Possible Causes | Troubleshooting Methods |
|---|---|---|
| Vacuum Cannot Be Eva"&"cuated | Seal Leakage/Pump Oil Contamination/Pipeline Blockage | Pressure rise rate test, leak detection/pump oil change/pipeline cleaning |
| Unstable vacuum | Large material venting/valve leakage/vacuum gauge malfunction | Inspect materials/leak detection/vacuum gauge calibration |
Power supply failure
| Phenomenon | Troubleshooting Methods | |
|---|---|---|
| Power Trip | Overcurrent/Overvoltage/IGBT Failure/Insufficient Water Cooling | Check Alarm Records/Measure IGBT/Check Water Flow |
| Unstable Power Output | Capacitor Aging/Power Grid Fluctuation/Control Board Failure | Measure capacitor capacity/Check powe"&"r grid/Replace control board |
Troubleshooting principles: Start with software before hardware (check software settings first, then hardware), s"&"tart with external conditions before internal components, start with simple checks before complex disassembly. If you encounter a problem you can't solve, contact the manufacturer for remote diagnostics.
