Pump for pipelines
Thread Content
There is currently a pipeline for transporting desalinated water; the first half of this pipeline has a diameter of 40, while the second half has a diameter of 80. The pipeline pump is installed at location 1. At present, the pressure drop in the 40-diameter section of the pipeline is quite high, which results in an insufficient amount of desalinated water being delivered. Would installing the pipeline pump at location 2 help to resolve this issue? ?
I think the effect is the same, unless a pipeline pump is also installed at point 2 in the circle.
No cavitation, which means the pressure drop at the front end is too high
What is the flow direction of the pipeline? Insufficient pipeline flow indicates that the total flow is inadequate; it is necessary to calculate the flow rate. If moving the pump meets the requirements, the pump can be moved.
Insufficient flow indicates that the pipe is too thin. If a DN40 pipe section is used as the pump inlet, the low pressure at the pump inlet results in an even smaller pressure drop that the pipeline can accommodate, preventing the liquid from being drawn in; I believe this would lead to poorer performance of the pump.
