The characteristics of the gas cylinder buffer and disadvantages

Characteristics and shortage in the cylinder of cylinder gas buffer technology, the internal structure of cylinder gas buffer itself with a mm or so. At run time using the pneumatic cylinder thrust, has the certain inertia, back and forth movement of the piston, cannot stop in time, so will inevitably impact on both ends of the cylinder end cover, air cushion is mainly in order to protect the end cover, avoid the end cover is directly fast collision of piston. Due to the cylinder itself with gas cushion, so a lot of friends think it don't need another buffer device, so more cost savings, but the idea is a myth. Reason has the following two points:, air cushion is rely on gas cylinder itself, the buffer force is small, when the workpiece is heavier, the cylinder to run faster, buffer gas effect is limited, can not have the effect of protection, this is must install hydraulic buffer to protect mechanical equipment; , air cushion is inside the cylinder, and the workpiece is run in the external, when artifacts and face contact of mechanical equipment, the inevitable impact and noise, air cushion is starting to function at this moment, so you want to install the external hydraulic buffer to protect mechanical equipment and reduce the noise! Are heavily dependent on gas cylinder gas buffer, buffer force is small, when artifacts bearing, cylinder speed quickly, the role of the air cushion is limited, and cannot protect, in turn, may cause the wastage of the cylinder, reduce its service life. This time must be installed oil buffer to protect mechanical equipment. Otherwise, the cost of the damage caused by the cylinder will greatly increase costs. Air cushion is happening in the interior of the rodless cylinder, and the workpiece is running outside, so the workpiece and the section of machinery and equipment contact inevitably impact noise, air cushion at this time for this kind of external noise is less than any role, so more external oil-pressure buffer should be installed to reduce the noise, the protection device, which can improve the production efficiency and save cost of enterprises.
