Festo cylinder DSNU-32-50-P-A-MQ

The FESTO cylinder drive system has been rapidly popularized in the field of industrial automation since the 1970s. Today, cylinders have become the mainstream actuators for PTP (PointToPoint) handling in industrial production fields both domestically and internationally. The market size of pneumatic components with cylinder drive systems as the core has reached a scale of 11 billion US dollars. Since the 1990s, the rapid development of electric motors and their microelectronic control technology has made the application of electric actuators in industrial automation possible. Moreover, the rise of the semiconductor industry has directly promoted the expansion of the application of electric actuators that can achieve high-precision multi-point positioning in the industrial field.

FESTO cylinders and electric actuators have always been considered as automation products belonging to two different fields. However, in recent years, with the continuous improvement of electrification, electric actuators have gradually entered the pneumatic field, and the two compete and complement each other in their applications. In this column, we will compare the advantages of cylinders and electric actuators from several aspects such as technical performance, purchase and application costs, energy efficiency, application scenarios, and market situation

Technical performance: Compared to electric actuators, cylinders can work reliably under harsh conditions, with simple operation and basic maintenance free capabilities. Cylinders are good at performing reciprocating linear motion, especially suitable for the various conveying requirements in industrial automation - the linear handling of workpieces. Moreover, simply adjusting the one-way throttle valves installed on both sides of the cylinder can achieve stable speed control, which has become a major feature and advantage of the cylinder drive system. So for users who do not have multi-point positioning requirements, the vast majority prefer to use cylinders from the perspective of convenience. At present, most applications of electric actuators in industrial sites require high-precision multi-point positioning, which is difficult to achieve with cylinders and is a secondary result.

Electric actuators are mainly used for rotating and swinging conditions. Its advantage lies in its fast response time and precise control of speed, position, and torque through a feedback system. But when it is necessary to complete linear motion, transmission conversion needs to be carried out through mechanical devices such as toothed belts or screw rods, so the structure is relatively complex, and there are high requirements for the working environment and the professional knowledge of operation and maintenance personnel.

The advantages of FESTO Festo cylinders in Germany:

(1) The requirements for users are relatively low. The principle and structure of the FESTO Festo DSNU series compact 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. FESTO FestoDSNUThe output force of a series of compact cylinders 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 FestoDSNUThe series of compact cylinders can work normally in high and low temperature environments and have dustproof and waterproof capabilities, which can adapt to various harsh environments. However, due to the large number of electrical components, electric cylinders have high environmental requirements and poor adaptability.
