Problems caused by slurry pump wear
The problems caused by the wear of the slurry pump are the key primary considerations of the slurry pump.
The centrifugal slurry pump is a type of centrifugal pump. It is a device that increases the energy of liquid water and solid particles by the centrifugal force generated by the rotation of the impeller of the pump. The design principle of the centrifugal slurry pump The design principle of the common centrifugal pump is basically the same. However, the slurry pump conveys a mixed fluid of liquid and solid, and its working medium is no longer just a one-way fluid. From this point of view, its design principle is different from that of ordinary centrifugal pumps. At this stage, the design of traditional slurry pumps in China is mostly based on empirical design based on the one-way flow theory. The slurry pump shaft seal designed by this design method has serious leakage, low working efficiency, poor wear resistance in the overcurrent part, and short service time.
At present, there are two major problems in the slurry pump work that need to be solved urgently:
First, the problem is the wear and tear of parts in the over-flow part of the slurry pump.
Second, the problem is the low efficiency of the centrifugal slurry pump.
Due to the over-current parts of the centrifugal slurry pump, it can directly cause the loss of working materials, and also cause a series of indirect consequences, such as safety problems, service life problems, etc. Fully reflected.
The problems caused by slurry pump wear are mainly manifested in:
1. Affect work efficiency. Due to the mutual wear of the gap between the impeller and the pump body, the internal volume efficiency of the pump is gradually reduced, and the unevenness of the overflow surface with the increase of wear and tear will seriously affect the working efficiency of the centrifugal slurry pump.
2. Increased maintenance time. Due to the increasing degree of wear and tear in the slurry pump, regular maintenance has been unable to ensure the normal operation of the slurry pump, which has significantly increased the number of repairs, and the maintenance work will gradually lengthen.
3. Reduce the running quality. The abrasion generated by the flow surface of the centrifugal slurry pump has the effect of unevenness, which promotes the development of local disturbance and cavitation of the water flow. The asymmetrical wear of the impeller will cause mechanical imbalance. These reasons will increase the vibration of the centrifugal pump, shorten the life of bearings and mechanical seals, and reduce the quality of operation
