About su pneumatic cylinder

Types of SU pneumatic cylinders

There are various types of SU pneumatic cylinders available that perform distinct functions using the same general principles. The following table outlines some of the typical types of pneumatic cylinders:

  • Double-acting cylinders: In a double-acting cylinder, the air causes the rod to move forward and backward. It consists of two ports: one for air intake and the other for air exhaust.
  • Rotary actuators: Rotary actuators transform linear air pressure into rotational movement. They are compact devices that typically contain a rotating shaft sealed bearings and gears that provide output torque.
  • Double-rod cylinders: A double-rod cylinder has a piston with a rod extending from each end. This type of cylinder is suitable when the load must be centered or when constant extension and retraction are required.
  • Cylinders with magnetic sensors: This type of sensor detects the piston position of the cylinder magnetically. It indicates the installation position of the cylinder actuator, which can help the user know the status of the actuator.
  • Cylinders with bumpers: Bumpers are usually made of thermoplastic elastomer. They provide dampening at the end of the cylinder stroke to reduce noise and vibrations.

Specifications and maintenance of SU pneumatic cylinders

Specifications

  • Materials: SU cylinders use a wide variety of materials like stainless steel, aluminum alloy, bronze, zinc alloy, carbon steel, etc., to stand up to different working environments.
  • Piston diameter: This refers to the diameter range available, which varies from manufacturer to manufacturer. For example, the SU model 16-50 has a diameter range of 16 to 50 mm, and the SU model 100-125 has a diameter range of 100 to 125 mm.
  • Stroke Length: The stroke length of SU pneumatic cylinders can vary depending on the specific model and design of the cylinder. For example, a short-stroke cylinder might have a stroke length of around 10 mm, while a long-stroke cylinder could have a length of up to 1000 mm or more.
  • Operating pressure: SU cylinders can be used under different pressures. Standard working pressure is usually between 0.1 to 0.9 MPa. High-pressure models can reach up to 1.6 MPa, thus extending the application range.
  • Temperature Range: The operating temperature range of an SU cylinder is influenced by the materials used in its construction. It is typical to be between -20 to +80 degrees centigrade. However, some high-temperature models can work in a range of -40 to +150 degrees centigrade.

Maintenance

  • Cleaning: The outer surface of the cylinder should be cleaned regularly to prevent dust and other particulate matter from entering the inside of the cylinder. A soft cloth and neutral detergent should be used for cleaning to avoid damaging the surface of the cylinder.
  • Inspection: Regular inspection of the cylinder should be conducted. This includes checking for leakage, deformation, loosening of parts, etc. If any abnormality is found, it should be repaired or replaced in time to avoid safety hazards.
  • Lubrication: Keep the cylinder and its accessories well lubricated. This reduces friction and wear, thereby prolonging service life. Special lubricant should be used for pneumatic equipment.
  • Seal replacement: The seal elements of the cylinder should be regularly checked and replaced if they are found to be aged, deformed, or damaged. This prevents air leakage and ensures air tightness and stability of movement.
  • Cleaning of accessories: The accessories connected to the cylinder, such as the quick couplings and the pipes, should also be cleaned and maintained regularly, which ensures reliable connectivity and smooth airflow.

Uses of SU pneumatic cylinders

  • Conveyor belt:

    Pneumatic conveying systems mainly rely on the power of air pressure and suction to move materials along with belts by using pneumatic cylinders to create airflow. This airflow moves the goods through a process known as aeration, where items are placed on a perforated plate and supplied with air until they float and can easily be moved along the system. This method not only efficiently conveys materials but also reduces friction and energy consumption.

  • Robots:

    Pneumatic SU cylinders are often found in the field of robotics. They can be used to adjust or move various parts of the robot. For instance, they can be employed for the adjustment of height or the opening and closing of clamps or grips. Robots equipped with pneumatic cylinders can be utilized in many different industries for purposes like assembly, picking, and putting, as well as for the handling of materials.

  • Packaging:

    Pneumatic cylinders are widely used in the packaging industry. They are employed in procedures like sealing, labeling, bottling, and filling. For example, bottling lines can make use of SU cylinders to rapidly and accurately position containers, ensuring that they are capped and labeled correctly. Moreover, the cylinders can also be utilized for the packing of products into boxes or bags and for the sealing operations.

  • The automotive industry:

    Cylinders are common pneumatic devices used in the automotive industry for assembly line production. As the main power source responsible for pushing, pulling, and rotating parts, they efficiently handle heavy-duty work. For example, SU cylinders can be used for the assembly of car bodies, the installation of parts like engines, or the clamping and fixing of workpieces. Their fast operating speed can greatly enhance production efficiency.

  • Injection molding machines:

    The core working mechanism of a pneumatic injection molding machine lies in its molding. This means that the shape of workpieces will be altered. For this reason, molds will have to be opened and closed as well as adjusted and positioned.

How to choose SU pneumatic cylinders

The following suggestions may assist microbusinesses and huge industrial sectors in selecting the proper SU cylinder for their needs.

  • Analyze application needs

    Determine the intended use by taking into account factors such as load weight, speed requirement, stroke length, and operating environment. Select a cylinder designed for high-temperature places, for example, if it will be exposed to high temperatures or contaminated with dust and chemicals.

  • Evaluate force and pressure

    The output force of the cylinder depends on the load weight and the pressure. Select an appropriate pressure and calculate a suitable cylinder size to generate the necessary force. The pressure is measured in pascals (N/m²), and the area of the piston is in meters squared.

  • Think about the mounting style

    Mounting types that are commonly used are fixed, trunnion, tied, and slotted mount. Decide how to install the cylinder to the other parts and choose a cylinder with an appropriate mounting style.

  • Choose an appropriate stroke length

    A stroke length that matches the required moving distance in the application should be selected. For some applications, if the required moving distance is beyond the available stroke lengths, multiple cylinders or a cylinder with a longer stroke length may be used.

  • Consider selecting a rod or a non-rod

    In applications that need compact design, a rodless cylinder with a sliding carriage can be used. It is also called a non-rod. For cost-effective solutions, consider cylinders with different piston rod materials and coatings.

  • Choose an actuating type

    A double-acting cylinder is one that moves fluid power in both extending and retracting phases; a single-acting cylinder is one that only uses internal springs to make it retract. Both options are relevant to specific applications, so consult with engineers to better comply with design needs.

SU pneumatic cylinder FAQ

Q1: What is the difference between a SU cylinder and a standard SU cylinder?

A1: The main difference between standard and non-standard SU pneumatic cylinders is their size and shape. Standard cylinders will have set dimensions, while non-standard or custom-made cylinders can be manufactured to a specific size or with a particular feature.

Q2: How does a SU rodless cylinder work?

A2: A rodless cylinder works by moving a load along its length. This is done by using a magnetic strip attached to the moving part of the cylinder and a static part that contains the pneumatically powered element. In this case, the SU element will drive the load along the length of the cylinder.

Q3: How long do pneumatic cylinders last?

A3: Depending on usage, combined factors, like the material of the cylinder and whether it has been lubricated or not, cylinders can last anywhere from two to twenty years. However, some factors may cause the cylinder to fail faster, like corrosion or not using the right lubrication.

Q4: What are the main types of SU cylinder?

A4: The main types are tie rod, sleeve, unclod, and non-contact cylinders. The most common of these is the tie rod as it is more durable and offers a better performance.
