German Festo FESTO cylinder DSNU-40-25-P-A

FESTO Festo cylinder is a pneumatic device developed by Festo, a pneumatic technology company. Their working principle is to convert the kinetic energy of gases into mechanical motion energy, and convert air pressure into linear or rotational motion. The following is the working principle and advantages of FESTO Festo cylinder:

working principle

The working principle of FESTO Festo cylinder is to send compressed air or gas into the cylinder. When the pressure inside the cylinder rises, the cylinder piston will move outward. Just like the piston in a car engine, the cylinder piston generates kinetic energy during operation. The working principle of FESTO Festo cylinders is simple, but they can precisely control and manage this air pressure, resulting in efficient and precise force output.

FESTO Festo cylinders have multiple advantages, including:

(1) High efficiency capability: FESTO Festo cylinders can generate high motion and force output in a short period of time, making them highly suitable for applications that require high efficiency capability.

(2) Accuracy: Due to the high-precision air pressure control and operational capability of FESTO Festo cylinders, the piston position and angle of the cylinder can be precisely controlled.

(3) Sustainability: FESTO Festo cylinders have the advantages of low energy consumption and sustainability, as they use gas as the driving force, making them highly suitable for applications that require low energy consumption and environmental protection.

(4) Durability: FESTO Festo cylinders are designed to be durable and of high quality, and after normal use and proper maintenance, they can last for several years.

(5) Wide applicability: FESTO Festo cylinders can be applied in multiple fields such as fluid operation, air operation, slow operation, and high-speed operation.

In summary, FESTO Festo cylinders have significant advantages in efficient, precise, and sustainable force output. Whether it's automated production lines, robotics technology, or other industrial applications, FESTO Festo cylinders are a reliable and effective pneumatic tool.

Selection of cylinders:

1. Choose the correct type of cylinder based on job requirements and conditions. A buffer cylinder should be selected to ensure that there is no impact phenomenon or impact noise when the cylinder reaches the end of the stroke; Light weight is required, and a lightweight cylinder should be selected; Require narrow installation space and short stroke, optional thin cylinder; There is a lateral load, and an optional guide rod cylinder is available; High braking accuracy is required, and a locking cylinder should be selected; Do not allow the piston rod to rotate, optional cylinder with rod non rotation function; Heat resistant cylinders should be selected in high-temperature environments; In corrosive environments, corrosion-resistant cylinders should be selected. In harsh environments such as dust, it is necessary to install a dust cover on the protruding end of the piston rod. When no pollution is required, oil-free or oil-free lubricated cylinders should be selected.

2. The installation form is determined by factors such as installation location and usage purpose. In general, a fixed cylinder is used. When continuous rotation with the working mechanism is required (such as lathes, grinders, etc.), a rotary cylinder should be selected. When it is required that the piston rod not only move in a straight line, but also swing in a circular arc, a pin type cylinder is selected. When there are special requirements, the corresponding special cylinder should be selected.

3. The magnitude of the applied force is the choice of cylinder diameter. Determine the thrust and tension output of the cylinder based on the magnitude of the load force. Generally, the required cylinder force is balanced according to the external load theory, and different load rates are selected based on different speeds to provide a slight margin for the cylinder output force. The cylinder diameter is too small, resulting in insufficient output force, but the cylinder diameter is too large, making the equipment bulky, increasing costs, and also increasing gas consumption, wasting energy. When designing fixtures, expansion mechanisms should be used as much as possible to reduce the external dimensions of the cylinder.

4. The piston stroke is related to the occasion of use and the stroke of the mechanism, but generally full stroke is not selected to prevent the piston from colliding with the cylinder head. If used for clamping mechanisms, a margin of 10-20 mm should be added according to the calculated required stroke.

5. The movement speed of the piston mainly depends on the input compressed air flow rate of the cylinder, the size of the cylinder inlet and outlet ports, and the size of the inner diameter of the conduit. High speed movement should be taken as the maximum value. The speed of cylinder movement is generally 50-800 mm/s. For high-speed cylinders, a large inner diameter intake pipe should be selected; For situations where the load changes, in order to achieve a slow and smooth movement speed, a throttling device or a pneumatic hydraulic damping cylinder can be used, which makes speed control easier to achieve. When selecting a throttle valve to control cylinder speed, it is recommended to use exhaust throttle speed regulation when horizontally installed cylinders push loads; When lifting loads with vertically installed cylinders, it is recommended to use intake throttle speed regulation; When it is required to move smoothly at the end of the stroke to avoid impact, a cylinder with a buffering device should be selected.
