The problem of slurry pump wear is mainly manifested in the:
1.The impact of work efficiency. Due to the gap between the impeller and the pump body mutually wear, the pump volume efficiency decreases gradually with the increase of flow surface wear and uneven phenomenon, seriously affect the efficiency of centrifugal slurry pump.
2. Increase the maintenance time. The slurry pump wear degree is more and more big, often can not guarantee the normal operation of the maintenance of slurry pump, the maintenance frequency increased significantly, and the maintenance work will gradually lengthen ask.
3. Reduce the running quality. The wear surface flow generated by centrifugal slurry pump, the formation of uneven consequences, promote? Local disturbance of flow and development of cavitation. Asymmetric wear of the impeller will result in mechanical imbalance. These reasons can make the centrifugal pump vibration, shorten the bearing and mechanical seal life, reduce the quality of the operation.
