Typical fault handling
1.Flow drop:
Check the impeller clearance (should be maintained at 0.5-1mm)
Verify the clogging of the inlet filter
2.Abnormal vibration:
Check the bearing wear (allowable vibration value ≤4.5mm/s)
(Note: It is recommended to match the Y-type filter (mesh number ≥20) and soft start device to extend the service life)
