The model of the slurry pump is selected based on the flow head provided on site. After the model is determined, the caliber of the slurry pump is also determined. However, the pipelines on site are not designed according to the caliber of the slurry pump. If the size is large What will happen if a large-diameter slurry pump is equipped with a small-diameter pipeline? Let's take a look.
Many users think that this can increase the actual lift of the slurry pump. In fact, the actual lift of the slurry pump is the total lift minus the loss lift. When the slurry pump model is determined, the total head is certain; the loss of head mainly comes from the pipeline resistance. The smaller the pipe diameter, the greater the resistance, so the loss of head is greater. Therefore, after reducing the pipe diameter, the actual head of the water pump is not only It cannot be increased, but will decrease, resulting in a decrease in water pump efficiency. In the same way, when a small-diameter water pump uses a large water pipe to pump water, the actual head of the water pump will not be reduced. On the contrary, the loss of head will be reduced due to the reduced resistance of the pipeline, so that the actual head will be increased. Some users also believe that when a small-diameter water pump uses a large water pipe to pump water, the motor load will inevitably be greatly increased. As everyone knows, the liquid pressure is only related to the head and has nothing to do with the cross-sectional area of the water pipe. As long as the head is turned on, the size of the impeller of the water pump remains unchanged. No matter how large the pipe diameter is, the pressure acting on the impeller is certain. However, as the pipe diameter increases, the water flow resistance will decrease, resulting in an increase in flow rate and an appropriate increase in power consumption. But as long as it is within the rated head range, the water pump can work normally no matter how the pipe diameter is increased, and it can also reduce pipeline losses and improve water pump efficiency.
