Centrifugal pump issues
Thread Content
I would like to ask everyone for advice. If the water pressure from various sources entering the inlet of a centrifugal pump is different, and these pressures combine before flowing into the pump, will this have any impact on the pump? Also, all this water is circulated using centrifugal pumps. I was wondering if it flows in directly in this way, meaning that water from farther away participates less in the circulation process, while water that is closer around circulates more quickly?
Water that is far away participates in the circulation to a lesser extent, while water that is closer around circulates more rapidly. Therefore, in order to make their circulation speeds consistent, throttle devices should be installed on the pipes located closer to the source of water.
1 This is the parallel mode in chemical fluid processes. 2 As long as the fluids from various sources converge at the pump inlet, they will inevitably reach the same pressure; provided that the pressure at the pump inlet meets the pump’s allowable cavitation margin requirements and the total flow rate is higher than the pump’s minimum flow rate, this will have no impact on the pump’s operation. 3 If the resistance losses in each circuit differ, the flow rate will not be distributed evenly. 4 As for whether it is near or far, it cannot be generalized; it also depends on the size of the resistance. For example, in a small pipe that is part of a close-loop system, its resistance is not necessarily lower than that of a large pipe in a far-loop system
What was said upstairs is very comprehensive. However, it’s best not to use it in this way.
