Re: Whats the right piping design?26 January 2009 at 1:29pm
There is obviously a lot more to this problem than you have chosen to tell me.
Without knowing any more, I must ask why you reduced the size of the pipelines? This only increases the friction losses in the lines assuming you are pumping at the same flow rate. This in turn would increase the KW draw from the motor which, in turn, would cause it to trip out.
I don't understand your comment: "the pump damaged the stator.”
What is the right size of the pipe between the suction and the discharge? We are using a 16-bar progressive screw pump. The size of the suction is an 8-inch diameter, but we reduced it to 4 inches and the discharge is reduced to 6 inches and we are pumping the heavy oil for about 750 meters away to the manifold. This tripped the motor and suddenly the pump damaged the stator. Do you think this piping design for this situation is right?
Have an insight or suggestion?
