4. Piston stroke
It is related to the occasion of use and the stroke of the mechanism, but generally does not choose a full stroke to prevent the piston and the cylinder head from colliding. If used for clamping mechanism, etc., the margin should be increased by 10 ~ 20㎜ according to the required stroke.
5, the movement speed of the piston
It mainly depends on the compressed air flow in the cylinder, the size of the cylinder inlet and exhaust port and the size of the inner diameter of the conduit. It is required that high speed motion should be taken to a large value. Cylinder movement speed is generally 50 ~ 800㎜/s.
For the high-speed moving cylinder, the intake pipe with large inner diameter should be selected; For the load changes, in order to get a slow and stable motion speed, you can choose a throttle device or gas-liquid damping cylinder, it is easier to achieve speed control. When selecting a throttle valve to control the cylinder speed, note that: when horizontally installed cylinders push the load, it is recommended to use exhaust throttle speed regulation; When vertically mounted cylinders lift load, it is recommended to use intake throttle speed regulation; When the end of the stroke is required to move smoothly to avoid impact, a cylinder with a buffer device should be selected.
