Centrifugal pump operation and characteristics 111
In order to find the total time required to accelerate the motor and pump, the area
between the motor speed–torque curve and the pump speed–torque curve is divided into
strips, the ends of which approximate as straight lines.
Each strip corresponds to a speed increment, which takes place within a definite time
interval. The vertical lines in the figure represent the boundaries of strips. In each of these
bands or speed interval, the average T
acc
is worked out.
In order to calculate the total acceleration time for the motor and the direct-coupled
pump, it is necessary to find the time required ...
