What Damage Will Evacuate the Slurry Pump Cause to the Equipment?

1. Intensified impeller wear: Because there is not enough slurry in the pump to lubricate and cool, the impeller will rub with air or a small amount of slurry for a long time, causing rapid wear of the impeller surface, thereby shortening the service life of the impeller. In addition, severe wear may also lead to an increase in the gap between the impeller and the pump body, affecting the pump flow and pressure.

2. Sealing damage: Evacuation will cause the sealing area to lack lubrication and cooling, which can easily cause overheating and wear of the seal, resulting in seal failure and leakage problems. This will not only pollute the environment, but may also cause safety hazards.

3. Pump shaft bending: Uneven stress and vibration may cause the pump shaft to bend, affecting the normal operation of the pump, and even making the pump unable to work. Long-term bending may also cause the pump shaft to break, causing greater losses.

4. Bearing damage: Vibration and abnormal stress caused by evacuation will accelerate the wear of the bearing and reduce its service life. In severe cases, it may cause the bearing to be stuck and prevent the pump from operating normally.

5. Mechanical seal failure: Mechanical seals are easily damaged in the evacuated state, and scratches and cracks may appear on the sealing surface, thus losing the sealing effect. Failed mechanical seals will cause slurry leakage and affect the normal operation of the equipment.

6. Pump body overheating: lacks the cooling effect of the slurry, and the pump body temperature will rise rapidly, which may cause the pump body to deform and affect the pump's accuracy and performance. Long-term overheating may also cause the pump body material to age and reduce its life.

7. Shorten the motor life: The motor load is unstable during evacuation and the current fluctuates greatly, which will cause damage to the motor and reduce the service life of the motor. In addition, excessive temperatures may burn the motor windings and cause damage to the motor.

To sum up, slurry pump evacuation will cause serious damage to all key components of the equipment, increase maintenance costs, and reduce the reliability and operating efficiency of the equipment. Therefore, during actual operation, the occurrence of exhaust should be avoided as much as possible to ensure the stable operation of the equipment.
