Operation Principles操作原則

For clockwise operation, Port 2 (P2) is open to atmosphere and air pressure is directed to Port 1 (P1). 為順時針操作,端口2(P2)是開放的氣氛和空氣壓力指向端口1(P1)。As the pistons move apart, the pinion rotates clockwise. 當活塞移動,小齒輪旋轉(zhuǎn)順時針。The linear movement of the pistons is converted to rotary活塞的直線運動轉(zhuǎn)化為回轉(zhuǎn)motion by the piston racks and the output pinion gear.運動的活塞架和輸出小齒輪。

For counter-clockwise operation, Port 1 is open to atmosphere and air pressure is directed to Port 2.為逆時針方向操作,端口1是開放大氣和空氣壓力是針對端口2。

The pressure differential moves the pistons together, rotating the pinion counterclockwise.壓差移動活塞,小齒輪逆時針旋轉(zhuǎn)。

For clockwise operation, Port 2 is open to atmosphere and air pressure is directed to Port 1. 為順時針操作,端口2是開放大氣和空氣壓力端口1。The air pressure compresses the springs and moves the pistons outward. 壓縮空氣壓力彈簧和活塞向外移動。As the pistons move apart, the pinion rotates clockwise.當活塞移動,小齒輪旋轉(zhuǎn)順時針。The linear movement of the pistons is converted to rotary motion by the piston racks and the output pinion gear.活塞的直線運動轉(zhuǎn)化為旋轉(zhuǎn)運動的活塞架和輸出小齒輪。

For counter-clockwise operation, Port 1 is open to atmosphere and air pressure is directed to Port 2. 為逆時針方向操作,端口1是開放大氣和空氣壓力是針對端口2。High pressure and/or spring force moves the pistons inward, rotating the pinion counterclockwise.高壓和/或彈簧力向內(nèi)移動活塞,小齒輪逆時針旋轉(zhuǎn)。
