Outlet of a feed pump, high-speed centrifugal pump, after it is started up
Thread Content
The reaction feed pump is a high-speed centrifugal pump, also of the multi-stage type. Currently, 12 threads have been opened on the pump’s outlet; four more threads and it will be fully open. The load on both the motor and the pump is around 70%. May I ask if I open all the valves, can I increase the processing volume?
No, the slight changes in the last few amounts are barely noticeable; reducing the system pressure will have an effect
Don’t your pumps have variable frequency control? Can’t you adjust the speed? The valves are already open wide enough; there won’t be any further effect unless the system pressure is reduced.
Just keep the pump outlet valve fully open; isn’t the control valve used to limit the flow? ?
It is indeed as you said. It doesn’t work
The control valve is fully open, but there’s still no effect
Just try turning it all on and you’ll know! ! ! !
When it is fully opened, there are some improvements; the pressure drop at the outlet decreases.
Try switching pumps, and then clean the pump inlet filter!
What exactly is the situation? Can’t increase the processing volume? Could you mention it before, but not now? In the second case, check the inlet filter before the pump to see if it is clogged, and also examine the entire pipeline for any flow-limiting valves.
