■ How to select orifice bore ■ Select orifice bore by the following method, when controlling cylinder speed with Speed Controller Constant Flow. ① Use the following calculation formula and find an necessary air flow rate in order to control cylinder at desired speed. (Calculation to find air flow rate) P ＋ 0.1013 D2 × L 　 Q ＝ 4.7 × 10-5 ×────×────── t 0.1013 　 Q ＝ Air flow rate (l/min(ANR)) 　 D ＝ Cylinder tube I.D.(mm) 　 L ＝ Cylinder stroke (mm) 　 t ＝ One-way stroke time (sec) 　 P ＝ Operating pressure (MPa) ② Use the chart of Flow Characteristic. Select 2 or 3 orifice bores which are closer...
