Cylinder speed, flow and pressure

Cylinder speed, flow rate and pressure: If the pressure of air source decreases or the air flow rate in and out of the cylinder decreases, the output of the cylinder will be insufficient. It may be that there is cross-gas in the front and rear cavities of the cylinder, resulting in insufficient output, blocked or knotted pipelines and reduced throttle. It may be that the sealing ring on the cylinder piston expands, which leads to the increase of internal friction.

Matters needing attention in cylinder control

In the control of the cylinder, it should be noted that the air is compressible, and the interference factors such as the friction between the piston inside the cylinder and the cylinder wall, the friction between the piston rod and the dustproof ring at the extension end of the piston rod will affect the time control. If the friction is large, the air will be compressed again, resulting in the delay of extending the time, which can be felt by holding the piston rod with your hand in the airless state.

The factors that affect the flow rate are the rated flow rate of directional control valve, the size of gas pipe joint, the length of gas path from solenoid valve to cylinder, the speed of intake and exhaust, and another important factor that will affect the speed and load rate of cylinder.

In order to improve the speed of the cylinder, it is necessary to use a large flow directional control valve, a thick gas pipeline, a large joint, shorten the distance between the valve and the cylinder, and use a quick release valve.
