The Relationship Between Slurry Pump Flow, Speed And Service Life

At present, 80% of slurry pumps are widely used in concentrators to transport ore slurry. Whether the flow rate and speed of the slurry pump are reasonable or not directly affects the life of the slag. Choosing appropriate working parameters can not only give full play to the performance of the slurry pump, but also increase the service life. If the selection is not appropriate, the slurry pump will not work normally, and may even cause the plant to stop production. In order to give full play to the performance of the slurry pump, it is necessary to fully understand the relationship between the slurry flow, speed, etc. and the life of the slurry pump in actual work.

Due to the flow of the slurry in the slurry pump, the slurry will impact and wear the lining of the pump body. Obviously for the same slurry flow rate, the slower the slurry flow rate, the lighter the wear of the pump body and the longer the service life of the slurry pump. Therefore, under the premise of ensuring the efficiency of the slurry pump, the design flow rate should be as small as possible. Furthermore, the lower the pump speed, the lower the relative speed of the impeller and the slurry, and the slower the wear rate of the impeller. In addition, at the same flow rate, the larger the diameter of the impeller, the lower the speed, the fewer ore particles per unit area, and the less wear of the impeller. Therefore, the correct choice should be a large pump with a low speed. Due to its light wear, it can prolong its service life and reduce costs. In addition to flow and speed, the head also has a certain impact on the life of the pump. The actual head of the pump must be controlled within the acceptable range, otherwise the head will be too high and the flow of the pump will be too large. On the one hand, the pumping phenomenon will be caused and the pump will be damaged. On the other hand, excessive flow will increase wear and reduce service life.
