1. Output force when selecting cylinder
According to the force required by the working mechanism, the thrust or pulling force on the piston rod is determined by considering the cylinder load rate to determine the inner diameter.
Because the working pressure of the cylinder is small (0.4~0.6MPa), its output force will not be very large, generally around 10000N (not more than 20000N). If the output force is too large, its volume (diameter) will increase, so the force expansion mechanism should be used as much as possible on pneumatic equipment to reduce the size of the cylinder.
2. Cylinder stroke when selecting cylinder
The cylinder (piston) stroke is related to its use occasion and the stroke ratio of the working mechanism. In most cases, the full stroke should not be used to avoid collision between the piston and the cylinder head. Especially when used in clamping and other mechanisms, in order to ensure the clamping effect, add an extra 10 to 20 mm margin according to the calculated stroke.
3. Cylinder movement speed when selecting cylinder
The movement speed of the cylinder is mainly determined by the needs of the driving working mechanism.
When the speed is required to be slow and stable, it is appropriate to use a gas-liquid damping cylinder or throttle speed regulation. The methods of throttling and speed regulation include: exhaust throttling is recommended for horizontal installation of thrust loads;air intake throttling is recommended for vertical installation of lifting loads. For specific installation circuits, see the content of the basic circuit. The use of a buffer cylinder can prevent the cylinder from impacting at the end of the stroke. Usually, the buffering effect of the buffer cylinder is only obvious when the resistance load of the buffer cylinder is low and the speed is not high. If the speed is high, there will often be a shock at the end of the stroke.
