Pneumatic cylinders come in different types, each designed to meet a specific function.
General-purpose cylinders:
General-purpose cylinders are suitable for light-duty tasks like product handling, assembly, and packaging. They come in different sizes and typical shapes. Also, they can use tie rods or no rods, along with other common construction methods.
Guided cylinders:
Guided cylinders are designed to control the movement of the rod and provide high lateral stability. They are ideal for applications where accurate motion control is essential. Their design features an integrated guide system that uses bushings or bearings.
Compact cylinders:
Compact cylinders, also known as mini-pneumatic cylinders, are smaller alternatives to general-purpose cylinders. They have the same functions and mechanisms as traditional cylinders. However, their space-saving design enables them to work in applications with limited spaces.
Heavy-duty cylinders:
Heave-duty cylinders have a larger diameter and are built with stronger materials. They can withstand high-impact tasks like forging, stamping, and steel processing. Also, they have high loads and offer long service life.
Rotary cylinders:
Rotary cylinders convert pneumatic energy into rotary motion. They are ideal for applications that require precise rotation, such as automated assembly lines, indexing, and valve control. Depending the design, the working stroke length can vary considerably.
Special-purpose cylinders:
Special-purpose cylinders include double-rod cylinders and anti-explosion ones. Explosion-proof anti-explosion cylinders can work properly in explosive environments. On the contrary, the double-rod one has a piston rod on both sides of the cylinder, thus allowing for smoother operation.
Load capacity
The load bearing capacity of the air cylinder is limited and the weight bearing capacity within the specified range should be ensured.
Operating pressure
Operating pressure is the pressure range within which the cylinder normally operates. Air cylinders typically work at pressures between 0.2 and 1.0 MPa and operating pressures outside this range can affect their performance and reliability.
Temperature range
The working temperature of the air cylinder is the temperature range it can work in. This is a critical factor for maintaining the normal operation of the cylinder in environments with temperature extremes.
Stroke
The stroke is the distance the cylinder's piston moves. The selection of the proper stroke length ensures the cylinder has adequate motion.
Connecting parts
The connecting parts include the shape and size of the cylinder's connecting ends, as well as the thread and plug type that make up the inlet and outlet ports. These Connecting parts ensure the cylinder can be properly fixed and connected in the application.
Regular cleaning
Pneumatic cylinders should be regularly cleaned to remove surface dust and dirt using a mild detergent and soft cloth or sponge. Avoid using abrasive materials that can scratch the cylinder surface.
Check for leaks
Regularly check for leaks from the seals and connectors of the pneumatic cylinder. This can be done by visually inspecting the sealing surfaces or by gently brushing soap water on the sealing surfaces to observe bubble formation.
If a leak is found, the damaged parts should be replaced or repaired in a timely manner.
Lubrication and oil addition
Proper lubrication is important for the normal operation of pneumatic cylinders. Use lubricants that are compatible with the seals of the cylinders, and apply them evenly to the seals and the sliding parts of the cylinder.
Pneumatic cylinders are commonly used in the following industries and scenarios.
Capacity and load:
Estimating the maximum force that the pneumatic cylinder will need to generate is the first step in selecting the appropriate cylinder. The load-carrying capacity must be equal to or more than the transition coefficient. The equation for external force must also take into account.
Installation space:
The cylinder's installation space is another important factor to consider when selecting a pneumatic actuator. Selecting a pneumatic actuator that occupies the proper space will make it very carefree to complete joints and pipe fittings during assembly and equipment with other mechanical parts.
Operating environment:
Another important factor is the performance of the pneumatic cylinder, impacted by the environment. For example, temperature, humidity, and dust all influence whether or not to choose a double-acting cylinder.
Seal system:
The kind of sealing system it possesses greatly impacts how well it performs and lasts, even if it seems unimportant. Users have a wide variety of options to choose from, ranging from two to ten seals. Finding the ideal compromise between performance and safety is the goal, which is essential for any seal system.
Shock absorbers and buffers:
This is not just a quest for comfort and quiet; it's also crucial to stop violent collisions from occurring. Buffers and shock absorbers reduce abrupt stops and the noise they produce, extending the life of equipment and many of the components.
Q1: How does a double-acting pneumatic cylinder work?
A1: A double-acting pneumatic cylinder uses compressed air to push the rod in and out. It has two ports for the air to come in and exhaust through. The double-acting cylinders are ideal for applications that need faster speed and greater force.
Q2: What are the two main parts of a pneumatic cylinder?
A2: The two main parts of a cylinder are the body and the end caps. The body is the rounded tube part and houses the moving rod and seals. The body is usually made of aluminum or steel. The end caps fit the body and are usually made from the same materials as the body. They house the rod and ports for the air to come in and exhaust through.
Q3: What controls the speed of a pneumatic cylinder?
A3: The flow control valve helps to regulate the speed of a pneumatic cylinder. By adjusting the valve in the cylinder, it can move faster or slower according to the needs of the application. Also, the size of the cylinder will determine if it moves the load with a normal speed or slower speed.
Q4: How long do pneumatic cylinders last?
A4: With proper maintenance and regular inspection, a cylinder can last between 5 and 10 years. However, the lifespan can be less if there is improper maintenance, lack of lubrication, regular exposure to harsh chemicals and environments, or if it operates at high speeds and pressure.
