How many times per minute for high-speed cylinder

Answer: Conservatively speaking, it can reach more than 350 times.

Cylinders should be used in high-frequency and high-speed situations. For special occasions, a higher-end brand should be used. Such as SMC, FESTO, etc. And they also have gap-sealed high-speed and high-frequency cylinders.



RequiredCylinderThe push-pull force determines the bore diameter of the cylinder. For example, if the required operating pressure is 5 kg and the push-pull force of the cylinder is 140 kg, the stroke will be 100. Select the cylinder: The cylinder with a bore of 63 has a working push-pull force of 155 and 140 under a pressure of 5 kgHowever, during the selection process, the selected cylinder diameter should be one size larger than the cylinder diameter that meets the conditions for rated pressure, so as to avoid danger due to insufficient push-pull force of the cylinder when the pressure drops.

Why is the high-speed cylinder fast

The piston movement speed of a standard cylinder is generally in the range of 50~500mm/s. However, in practical applications, there are many applications that need to increase the cylinder speed, such as high-speed handling devices, CNC The equipment door opening and closing action, the high-speed Z-axis of the robot, etc. are shown in the figure below. These applications often place high demands on cylinder speed.



For example, the high-speed Z axis requires the cylinder speed to reach 3m/s, and the high-speed handling device with lower speed requirements also requires the cylinder speed to reach 1000mm/s. Standard cylinder< If the speed of /span> is higher than 500mm/s, the friction and heat generation of the cylinder sealing ring will intensify, accelerating the wear of the sealing ring, causing air leakage, shortening the cylinder life, and increasing the impact force at the end of the stroke, affecting the mechanical life.

In order for the cylinder to work at a higher speed, it is necessary to lengthen the length of the cylinder barrel, improve the machining accuracy of the cylinder barrel, and improve the material of the sealing ring to reduce friction and improve buffering. Performance etc. SMC has developed a specialized high-speed cylinderThe RHC series adopts a special structure with a long buffer stroke and a large air inlet diameter, which can ensure that the piston reaches a maximum movement speed of 3m/s and can decelerate smoothly.
