i'm runing a model of pump station
(OP)
i'm runing a model of pump station and i have simulated, using AFT impulse as software, the shut off of pump and the surge caused by it, so i have surge around 300 bar in upstream and downstream pipes (DN400 and DN500). i don't know if surge can reach such pressure !!
I feel like i'm missing something!

Hi BigInch ;
the velocity equal for 1.4 m/s. the steady state pressure is 17 bar.
hi MFJewell ;
i'm working on pump instantaneously going shut in water pump station,the distance between station and discharge tank is 10 km
RE: i'm runing a model of pump station
It might be thinking that you're creating a vacuum which then collapses as flow reverses D/S the pump.
This can create a large pressure, but it's not real for your situation. Try and put in a slow down mode for the pump, even of 3-5 seconds might be enough.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
RE: i'm runing a model of pump station
thx for your replie,i will try it, i want to ask about the difference between transient model of pumps:
-No transient-Four quadrant
-Trip with Inetia and no back flow or reverse speed
-Trip with inertia- Four quadrant
-Start up with Inetia and no back flow or reverse speed
-Start up with inertia- Four quadrant
-start up- Four quadrant known speed
RE: i'm runing a model of pump station
In this case you are looking at what happens when you shut down a pump so it would be the Trip with inertia. Then you need to determine if backflow can happen and that will help you decide if you are using four quadrant or not.
