Common Faults And Solutions for Crack Sealing Machines

Common Faults And Solutions for

1. Nozzle Clogging in Pipeline

• Unclogging Method: Clean discharge outlet with steel needle or thin wire, or disassemble and clean mixing pipe.

• Material Level Check: Replace asphalt sealant promptly when depleted to ensure continuous operation.

2. Heating System Abnormalities

• Insufficient Thermal Oil Temperature: Extend heating time to ensure both material and oil reach set temperatures (burner activates only when both parameters are met).

• Cold Weather Adaptation: Use low-temperature mitigation devices or preheat materials to prevent sealant freezing and thickening.

3. Mechanical Component Failures

• Agitator Jamming: Check for loose motors or chains; replenish lubricant or adjust chain tension.

• Spiral Blade Deformation: Disassemble and inspect blades; replace severely worn components with wear-resistant parts.
