After the screw pump is running idle, if handled properly, the damage to the spare parts can be minimized.
1. Immediate shutdown & coolingStop the pump at once; cool naturally to room temperature. Do NOT disassemble when hot to avoid deformation
2. Comprehensive component inspection
– Check stator for cracking/deformation/severe wear → replace if damaged irreversibly Inspect rotor for scratches/eccentricity → verify dimension tolerance
– Examine shaft seal/bearings → replace heat-damaged parts
3. Troubleshoot root cause
Identify the trigger (sensor failure/operational mistake) and resolve completely before restart.
4. Test run before normal operation
Conduct short no-load test with sufficient medium; monitor pressure/temperature/noise for stable operation.
