The difference between double-acting cylinder and single-acting cylinder, how to adjust the speed of double-acting cylinder

▋ The difference between double-acting cylinder and single-acting cylinder

Single-acting cylinder: can only rely on the driving force of gas to move forward or backward, and the recovery action depends on the spring Thrust or retraction.

Double-acting cylinder: It can move back and forth by gas.

Single-acting cylinders have only one air pressure hole and a spring. Double-acting cylinders have two air pressure holes and no springs. Single-acting cylinder and double-acting cylinder. The difference is that there is a spring in the single-acting cylinder. From the appearance, the double-acting cylinder has two ports that can be connected to the air pipe, while the single-acting cylinder has only one. I thought that I should use a brand name, as the service life of other brands will be problematic. If it is used in precision places such as molds, the cylinder used will affect the mold. , the smaller one will affect the output, and the larger one will not even be able to clamp the product die, causing huge losses.

▋ How to adjust the speed of a double-acting cylinder

Generally, pneumatic speed control valves (one upper and lower) are installed on the pneumatic cylinder. Now take the end of the cylinder with the piston rod as the top and the end without the piston rod as the bottom. Then, if you want the cylinder to rise slower, turn down the speed control valve for exhaust air at the top (do not adjust the bottom);if you want the cylinder to descend slowly, turn down the speed control valve for the exhaust air at the bottom (do not adjust the top);On the contrary, if you want it to rise or fall quickly, turn it up. Try not to adjust it up and down at the same time. Adjust it a little and try it out, then adjust it a little more, and it will be adjusted to the ideal speed in no time. If pneumaticcylinder There is no speed regulating valve (one-way throttle valve) installed on it, then buy two and install them, and just adjust them as instructed.
