Compact pneumatic cylinders are a type of pneumatic cylinder specifically designed to maximize output force and motion within limited spaces.
Unlike standard cylinders, compact pneumatic cylinders feature a shorter body length while providing the same stroke capability, making them ideal for use in applications where space is constrained.
They are known for their robust construction, which ensures reliable performance and high durability, even under demanding conditions.
When selecting a compact cylinder for your application, the following factors are critical in ensuring proper performance and compatibility with your system requirements:
◆ Determine Working pressure: Know the pressure range of your pneumatic system, typically measured in pounds per square inch (psi). Compact cylinders must be compatible with your system's pressure levels.
◆ Calculate Force Required: The output force of pneumatic cylinders can be calculated by the formula:
Force=Pressure×Piston Area
◆ Pressure: The operating air pressure supplied to the cylinder (in psi or bar).
◆ Piston Area: The cross-sectional area of the piston, which can be calculated based on the cylinder's bore diameter.
◆ Sizing: Select a cylinder with sufficient bore size to produce the required force at your available pressure. Ensure that it has a safety margin to account for load variations.
◆ Required Stroke Length: This is the distance that the piston rod must travel to complete its intended task. Ensure the cylinder’s stroke length meets your application's needs without excess or shortage.
◆ Compact Cylinder Advantages: Since compact cylinders are designed to minimize space while providing the necessary stroke, it's essential to verify that their length and size fit within your spatial constraints.
◆ Mounting Style: Compact cylinders offer various mounting options such as foot mounting, flange mounting, through holes, and more. Select a mounting option that best fits the mechanical setup of your application.
◆ Footprint: The cylinder's physical size and shape are important considerations, especially in applications with space limitations. Ensure that the cylinder’s overall footprint and mounting type align with the available installation area and any relevant constraints.
◆ Spring Return (Single-Acting): In a single-acting cylinder, compressed air is applied to move the piston in one direction, while a built-in spring returns the piston to its original position when the air is removed.
This configuration is useful for applications requiring return-to-home positioning or fail-safe operation. However, it provides force in only one direction.
◆ Double-Acting Cylinders: These cylinders use air pressure to move the piston in both directions. Double-acting cylinders offer consistent force output and greater control over motion in both extending and retracting directions, making them ideal for a broader range of applications, including those requiring bidirectional force.
When using compact pneumatic cylinders, the following factors should be considered:
◆ Ambient Temperature: Ensure the pneumatic cylinder operates within the recommended temperature range to avoid damage or reduced performance.
◆ Media Temperature: Consider the temperature of the compressed air or gas used in the cylinder, as extreme temperatures can affect seals and other internal components.
◆ Environment: Take into account external conditions such as humidity, dust, and corrosive substances, which can cause wear or reduce the cylinder’s lifespan.
◆ Excessive Loads: Avoid applying forces beyond the specified axial load capacity of the cylinder, as excessive pressure can lead to failure or malfunction.
◆ Load Guiding (Non-Rotating): Ensure the cylinder has proper guidance for non-rotating applications to maintain stability and prevent misalignment or excessive wear.
These considerations are essential for maintaining the reliability and longevity of compact pneumatic cylinders.
Compact Cylinders are commonly used in automation, robotics, assembly lines, and other applications where space constraints are critical.
Stroke length: Compact Cylinders typically feature short strokes, ideal for applications requiring precise, small-range movements.
Bore size: Available in various bore sizes, such as 16mm, 20mm, 25mm, etc.
Materials: Most Compact Cylinders are made from aluminum alloy or stainless steel for strength and corrosion resistance.
When selecting a Compact Cylinder, consider the required dimensions, stroke length, force output, and mounting options based on the specific needs of your application. Ensure that the selected cylinder meets the load and space requirements.
Regularly check seals and moving parts to avoid wear and leaks.
Clean the exterior of the cylinder to prevent dust or debris from entering and affecting its performance.
Inspect the cylinder for signs of excessive wear, and replace components as necessary.
The working principle of a Compact Cylinder is similar to that of a standard pneumatic cylinder. Compressed air drives the piston inside the cylinder, creating mechanical force. The compact design allows it to function in space-constrained environments while maintaining performance.
Air leakage: This could be due to worn or damaged seals.
Sluggish movement: This may be caused by insufficient air pressure or internal contamination.
Excessive wear: Over time, internal components may wear out, affecting cylinder performance and smooth movement.
The load capacity of a Compact Cylinder depends on its bore size and stroke length. Typically, a larger bore size means a higher load capacity. However, due to their compact design, these cylinders are generally not suitable for handling extremely heavy loads.
