I'm looking at my pump curve and where i want to be, 600-800 is too far off. my head would be really low and cavitation could occur. I think I might need to consider a new impellar. any sugestions would help.
I am considering purchasing a new variable speed motor. Something that can operate at steady state 400gpm, and then for cold starts, around 600-800gpm. I guess I need to know if the pump can handle these new requirements.
I understand that increasing the rpms will increase flow but how to know how many rpm's i can increase to before problems arise? My current motor is 10hp rated at 1770 rpm. Verticle turbine pump, 6 stages.
thanks
I can access the sump but while blowdown is occuring there is lots of steam and hard to see. I'm thinking of making some type of floatation device attached to a pole and measure the height and time during blowndown. I have concrete drawings so know the area of the sump. I think that this is...
I am currently working on a problem at a power plant where a sump is overflowing due to the cold start of two units at the same tim. The original sump was not designed to handle the blowdown that has recently been rerouted there. I have been trying to get some measurements on how much blowdown...
