B Plunger Information
B.1
Typical Plunger Force
Tecan Systems specifies that all new XLP 6000 Pumps running at a speed of
5600 pulses/sec will lift a 15-pound weight attached to the plunger drive pin.
Tecan Systems cannot warrant the pump for use beyond these specifications.
B.2
Plunger Time Calculations
Following are calculations for determining XLP 6000 plunger speeds. Four
different cases are presented below.
1
Start, top, and cutoff speeds are equal, or top speed is less than 50 Hz.
2
Typical move with ramp up, constant speed and ramp down.
3
Move is too small to reach cutoff speed.
4
Move is too small to reach top speed.
Note: Plunger move times have been calculated with backlash compensation set
to 0. [K<0>]
