My centrifugal pump cannot pump the fluid but it can buid pressure at discharge(I think it might be the shut off head since the pump performance drop is possible). But then the motor trip, pump shutdown. Can anybody tell me that why the motor trip?
Is it becuase off motor need to generate more...
If the condensate flashing in the pump, I think it would be a cavitation but I didn't hear any noise. And I also find the condensate came out instead of gas/vapor in the discharge side when I try to bleed the vapor.
If this is my misunderstood please educated me.
ps. there's a long way to go from the pump discharge to the CSD. The system is about 32 ft up verticaly. I also think if there are any fouling in the pipe which will cause a higher head (but for this, the fouling must make a diameter 20% smaller)
My vertical can pump (centrifugal) cannot pump the light end condensate from the HPKO drum which pressure is ambient to the Condensate Surge Drum (P = 270 psig). Firstly, I think it might occur from lower S.G. from the designed value (S.G. = 0.65) which will effect in insufficient of head due to...
This is the first time for me to deal with reciprocating pump.
I'd like to know how to select the pump.
How different in the choosing process between reciprocating pump and centrifugal.
I was assigned to find the optimum point to overhaul the compressor. First, I tried to find the polytropic efficiency tendency in MS Excel but it show such a linear line parrarel with x-axis (hour of operation). Does anyone have an idea what parameter should I consider instead of efficiency.
