The reasons for burnout are as follows:
1. The packing gland is pressed too tightly to cause burning of the packing (asbestos rope, oil-soaked asbestos, PTFE, etc.).
2. The reason for the material itself.
3. Insufficient water supply in the sealed cavity of the pump causes burnout.
4. The rotor parts run too much and cause the bushing to grind the inner circle and then burn the packing.
5. The packing ring and the shaft sleeve are rusted, causing the packing to lock up the shaft sleeve and burn out.
6. The axial movement frequently causes the packing to become tight and then starts to burn the packing.
7. The pump burns out the packing after dry grinding.
