I have a butterfly valve right after the pump.
I did calculate the flowrate, that's why I've start the pump at 50% capacity at the VFD.
LittleInch, I believe you're right. The system won't produce a high pressure drop, so the visual effect of the fluid leaving the pipe won't be turbulent.
Many thanks for all the answers.
Measured flowrate?
Maybe it's an option. I'll consider.
The more info you disclosed the more this system seems like there is no engineering behind that.
You're right. I inherited this problem as soon as I was hired.
(2) significant flow restriction at suction...
Thanks for all the answers.
What are items 2 and 6 on drawings?
2 and 6 are the flange fittings, because the welding neck and the flange are sold separately.
In such case why the reducer 7 at the very left of drawing is not connected to the left tee? Why to elbow 4 at the very left of drawing...
Sorry for the absence, guys.
I also believe that it is a small pipe.
I prime the system and start the pump with the VFD at 50% and it works.
But if the tank's level gets lower, the system stops.
The main concern here is that the pump doesn't deliver the design flowrate. That's why I'm...
Thanks for pointing out. Didn't see that the image was illegible.
At the suction side I have:
1 foot valve
2 elbows
1 straight tee (where I have a valve for priming thr system)
6m of linear pipe
At the discharge side:
2 elbows and 9 m of linear pipe before three branches (two tees and an elbow)...
Hi all!
I need help with commissioning this pump. The design engineer is not around anymore and now I'm responsible.
The idea is to use the centrifugal pump to recirculate and agitate the liquid in the tank.
The piping has an internal diameter of 90 mm. I've already made some calculations for...
