Calculation formulas
The emptying time of cartridge P1 needs to be determined. With multiple
axles per FlexxPump, the axle most traveled needs to be taken into consider-
ation for the calculation (on linear gantries, this is typically the Y-axis).
The following specifications of your application are needed:
• Average velocity of the axle (vm) in m/s
• Operation time (t) of the system per day in hours
• Power-on time (POT) in %
The following values need to be calculated for P1:
