I am sorry for my poor english.[sadeyes]
after rmw's explaination, I understand what the check valve Montemayor mentioned is use for.
What rmw's understanding of my question is very well. the check valve is applied to prevent the backflow from the bypass loop beacuse of the higher pressure in...
Montemayor,
Thanks for your suggestion.
I have ever seen the foot valve you mentioned, it is used for maintenance. is it right?
I know that the pressure drop across the check valve maybe very small, but the pressure to open it maybe larger. In the low flow rate condition, the check valve maybe...
Anybody has ever seen a check valve installed in the suction line of a centrifugal pump? I am now in a design project, we have a buffer vessel for a centrifugal pump and the bypass line for the buffer vessel, in normal condition the centrifugal pump the fluid through the buffer vessel, but in...
vanstoja,
I am sorry that I can not understand very well the words that "if the stator windings are protected from coolant immersion by a non-magnetic metal sleeve/liner/can then stator can losses will occur".
is that words meaning the magnetic loss?
vanstoja,
I have checked all the centrifugal pump torqe curve I had ever contacted, most of them just like what you said that the curve is a parabola. But only only fire water pump is different, which was made by FLOWAY Company and required to start with the discharge valve fully open.
The value...
