Spot Festo Pneumatic YSR-12-12-C (34572) Pneumatic Hydraulic Buffer

The FESTO cylinder determines the thrust and tension on the piston rod based on the required force for operation. When selecting a cylinder based on this, there should be a slight margin for the output force of the cylinder. If the cylinder diameter is selected too small, the output force is not enough, and the cylinder cannot work normally; However, a large cylinder diameter not only makes the equipment bulky and costly, but also increases gas consumption, resulting in energy waste. When designing fixtures, force increasing mechanisms should be used as much as possible to reduce the size of the cylinder. Below is the formula for calculating the theoretical output of a cylinder: F: cylinder theoretical output force (kgf) F ': output force at an efficiency of 85% (kgf) - (F'=F × 85%) D: cylinder diameter (mm) P: working pressure (kgf/cm2) Example: What is the theoretical output force of a cylinder with a diameter of 340mm and a working pressure of 3kgf/cm2? What is the output of sprouts? Connect P and D, find the points on F and F ', and obtain: F=2800kgf; F '=2300kgf When selecting the cylinder diameter in engineering design, it can be found from experience table 1-1 based on its operating pressure and theoretical thrust or tension. Example: There is a cylinder with a working pressure of 5kgf/cm2, and when the cylinder is pushed out, its thrust is 132kgf (cylinder efficiency is 85%). Question: What is the cylinder diameter to choose? Based on the cylinder's thrust of 132kgf and efficiency of 85%, the theoretical thrust of the cylinder can be calculated as F=F ′/85%=155 (kgf). Based on the operating pressure of 5kgf/cm2 and the theoretical thrust of the cylinder, the selected cylinder diameter can be determined? A 63 cylinder is sufficient to meet the usage requirements.

Classification of Festo Valve Islands

Compact Festo Valve Island (CP Valve Island)

The technology that corresponds to the development of modular automatic production lines is decentralized control Distributed control has been increasingly widely applied in complex and large-scale automation equipment On such devices, there are often basic actions to complete specific tasks The series of actions of grabbing, turning, and placing processed parts require an action unit composed of pneumatic fingers (or vacuum suction cups), swinging cylinders, and ordinary cylinders In order to reduce the airflow loss in the cylinder control pipeline, the control solenoid valve should be installed as close as possible to these action units.

Due to the requirements of distributed control systems, a compact valve island (CP valve island) composed of CP type compact valves has emerged The compact valve island has a small appearance, but the output flow rate is very large, that is, its volume/flow ratio is particularly large. This is the difference between compact valves and micro valves. For example, the 14mm thick CP valve can provide a large flow rate of 800L/min, and the 18mm thickness can reach 1600L/min.
