Phenomenon: reduce the degree of vacuum and exhaust enough reasons: 1. Pipeline leak 2. Packing seal wear 3. Mechanical seal, static ring wear or spring imbalance 4. Impeller and end cap clearance is too large 5. Water ring temperature is too high 6. Water supply is insufficient Treatment: 1. To eliminate leakage 2. Dianniao replacement 3. Overhaul 4. Adjust the gap 5. Increase the amount of water to reduce the water temperature 6. To increase the water supply phenomenon: excessive vibration and parts of the reasons: 1. Circulating water is too large 2. Axis bending 3. Shaft and impeller mismatch, rotor skew 4. Rotor imbalance 5. Bearing damage 6. Packing too tight 7. Bearing lubrication is poor 8. Anchor bolts loose Treatment: 1. Adjust the amount of water 2. Align or replace 3. Adjust or overhaul 4. Find balance 5. Replace the bearing 6. Adjust the gland 7. Check the lubrication 8.
