German Festo FESTO cylinder ADN-S-20-10-I-P

The advantages of FESTO Festo cylinders in Germany:

(1) The requirements for users are relatively low. The principle and structure of FESTO Festo cylinder are simple, easy to install and maintain, and have low requirements for users. Electric cylinders are different. Engineering personnel must have a certain level of electrical knowledge, otherwise it is highly likely to be damaged due to misoperation.

(2) High output power. The output force of FESTO Festo cylinder is proportional to the square of the cylinder diameter; The output force of an electric cylinder is related to three factors: cylinder diameter, motor power, and screw pitch. The larger the cylinder diameter and power, and the smaller the screw pitch, the greater the output force. A cylinder with a diameter of 50mm theoretically has an output force of 2000N. For electric cylinders with the same diameter, although different companies have different products, they generally do not exceed 1000N. It is obvious that cylinders have an advantage in output force.

(3) Strong adaptability. FESTO Festo cylinders can work normally in high and low temperature environments and have dust and water resistance, adapting to various harsh environments. However, due to the large number of electrical components, electric cylinders have high environmental requirements and poor adaptability.

form:

1) Cylinder barrel

The inner diameter of the cylinder represents the output force of the cylinder. The piston should perform smooth reciprocating sliding inside the cylinder, and the surface roughness of the cylinder inner surface should reach Ra0.8 μ m.

SMC and CM2 cylinder pistons are equipped with composite sealing rings to achieve bidirectional sealing, and the piston and piston rod are connected by rivets without the need for nuts.

2) End cap

There are intake and exhaust ports on the end cover, and some also have buffer mechanisms inside the end cover. The end cover on the rod side is equipped with a sealing ring and a dust ring to prevent air leakage from the piston rod and prevent external dust from entering the cylinder. A guide sleeve is installed on the end cover of the rod to improve the guiding accuracy of the cylinder, withstand a small amount of lateral load on the piston rod, reduce the downward bending of the piston rod when it extends, and extend the service life of the cylinder. The guide sleeve usually uses sintered oil containing alloy and forward leaning copper castings. In the past, malleable cast iron was commonly used for end caps. To reduce weight and prevent rust, aluminum alloy die-casting was often used, and brass material was used for micro cylinders.

3) Piston

The piston is a pressurized component in the cylinder. To prevent air leakage between the left and right chambers of the piston, a piston sealing ring is installed. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston sealing ring, and reduce frictional resistance. Wear resistant rings are made of materials such as polyurethane, polytetrafluoroethylene, and synthetic resin for fabric clamping. The width of the piston is determined by the size of the sealing ring and the necessary length of the sliding part. The sliding part is too short, which can easily cause early wear and jamming. The materials commonly used for pistons are aluminum alloy and cast iron, while pistons for small cylinders are made of brass.

4) Piston rod

The piston rod is the most important load-bearing component in the cylinder. High carbon steel is usually used, with a surface treated with hard chrome plating, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring.

5) Sealing ring

The sealing of components at the point of rotation or reciprocating motion is called dynamic sealing, while the sealing of stationary parts is called static sealing.

There are several main methods for connecting the cylinder and end cap:

Integral type, riveted type, threaded connection type, flange type, pull rod type.

6) When the cylinder is working, it relies on the oil mist in the compressed air to lubricate the piston. There are also a small number of lubrication free cylinders.
