The system is connected with VFD(variable frequency drive) where shaft rpm can be changed.
I got clarity on what happens to the flow when identical pumps are connected in parallel.
thank you
hi artisi
can you please explain the relation between rpm of the shaft and percentage of load at which motor is working. elaborating.... if my motor is working at 80% of full load what is my rpm of the shaft?
Thank you ashtree,
yeah I learnt that pumps connected in parallel increases the flow typically by 10-25%. that's what actually happening in the system.
pump specifications:
Max Rpm at full load:2948 RPM
Amp: 50 amperes
power: 30 kw
Q: 180 cubicmetres per hr
two such pumps are connected to inlet header and outlet header of the chillers evaporator. basically its a circulation loop.
my query is when i measure flow rate in the header by using...
