Hi folks,
I am involved in retrofitting some equipment which will require an upgraded pump. The current pump is driven by a 1000kW motor, while the new pump will have a requirement of 1200kW. Rather
than buying a new 1200kW motor and throwing away the 1000kW motor we are considering installing a second motor rated at around 200kW to assist the first motor. We will obviously interlink the
motor starters so that if one motor drops out the second one drops out as well. We will also look at the torque vs. speed curves of the motors as well as the pumps to make sure that we can provide
sufficient accelerating torque during start up.
Has anyone heard of this being done before?
What are the implications?
Any specific problem that we should look out for?
The existing 1000kW motor runs at 11kV. A 200kW motor is small for this voltage and therefore expensive so that we are considering using a low voltage 380VAC motor. Does this have any possible
negative implications?
Thanks
