BAGIAN-BAGIAN SYSTEM PNEUMATIC

Summary

In this educational video, Ibrahim Muhammad Amin introduces the components of a pneumatic system. Key elements discussed include compressors, air service units, valves, and actuators, explaining their functions and how they contribute to the overall system. The video covers the operation of different types of valves such as 3/2 and 5/2 valves, as well as single and double-acting actuators. Detailed explanations are provided on how these components work together to power pneumatic systems, offering valuable insights for those looking to understand the practical application of pneumatic technology in engineering.

Takeaways

• 😀 The compressor is a crucial component in a pneumatic system, responsible for collecting air and storing it in a reservoir tube for use as energy to drive actuators.
• 😀 The compressor operates by pulling an on-off lever to begin collecting air, which is stored in the reservoir until it reaches full capacity and then stops automatically.
• 😀 The air collected in the reservoir is channeled through an outlet pipe, and excess air can be released using a yellow button on the compressor.
• 😀 The Air Service Unit, also known as the filter regulator and lubricator, filters water vapor, adjusts air pressure, and lubricates the pneumatic system.
• 😀 The Air Service Unit consists of several parts: an inlet port, a filter tube, a pressure regulator, and a lubrication tube that helps ensure smooth operation of the pneumatic system.
• 😀 Pneumatic system actuators typically require air pressure ranging from 4 to 5 bar to function effectively.
• 😀 A 3/2 valve has three air channels: an inlet air channel, an outlet air channel, and an exhaust channel. It can be operated with a push-pull button mechanism.
• 😀 The 3/2 valve with solenoid actuation uses electrical voltage to move the valve plug, and when voltage is removed, a spring returns it to its original position.
• 😀 The 5/2 single solenoid valve has five ports and operates with two positions (left and right), where the solenoid controls the movement of the valve plug between these positions.
• 😀 The 5/3 double solenoid valve has five ports and three positions (left, middle, and right). It uses two solenoids to move the valve plug between these positions.
• 😀 Single acting actuators require air pressure on one port to move the piston out, while a spring returns the piston to its original position. Double acting actuators require air pressure on two ports for both outward and inward movement of the piston.

Q & A

What is the primary function of the compressor in a pneumatic system?

The primary function of the compressor in a pneumatic system is to collect air from the surroundings and store it in a reservoir tube. This stored air is then used as energy to drive actuators in the system.

How does a compressor work once connected to a voltage source?

Once connected to a voltage source, the on-off lever on the compressor is pulled to activate it. The compressor collects air and channels it into the reservoir tube. The compressor stops collecting air when the reservoir is full, and the lever returns to the off position.

What is the role of the air service unit in a pneumatic system?

The air service unit, also known as the filter-regulator-lubricator, filters the air, adjusts the air pressure entering the pneumatic system, and provides lubrication to the system’s mechanical parts.

How does the air pressure in the pneumatic system get regulated?

The air pressure is regulated by the regulator in the air service unit. The pressure value can be adjusted, and it is displayed on a manometer, typically set between 4 to 5 bar for pneumatic actuators.

What is the function of the lubrication tube in the air service unit?

The lubrication tube provides lubrication to the mechanical parts in the pneumatic system. Lubricating oil is pushed through the tube by air pressure to ensure smooth functioning of these parts.

What does a 3/2 valve do in a pneumatic system?

A 3/2 valve controls the flow of air through three channels: the inlet, outlet, and exhaust. It has two positions that allow the air to either flow into or out of the system, or be exhausted, depending on the valve's position.

How does a 3/2 solenoid valve differ from a push-pull 3/2 valve?

The 3/2 solenoid valve is actuated electrically by a solenoid, whereas the push-pull 3/2 valve is manually operated by a push and pull button. The solenoid moves the valve plug when voltage is applied, and the spring returns it when the voltage is removed.

What are the differences between a 5/2 single solenoid valve and a 5/2 double solenoid valve?

The 5/2 single solenoid valve has one solenoid that controls the movement of the valve plug, while the 5/2 double solenoid valve has two solenoids, each controlling the movement in opposite directions. The double solenoid valve offers more control by using two solenoids to shift the valve plug.

What is the function of a 5/3 double solenoid valve?

A 5/3 double solenoid valve has five ports and three positions for the valve plug: left, middle, and right. It is controlled by two solenoids, allowing for more complex control of air flow in the system.

What is the key difference between a single-acting actuator and a double-acting actuator?

A single-acting actuator uses one inlet port to move the piston in one direction, and a spring returns it to its original position. A double-acting actuator requires two inlet ports to control the movement of the piston in both directions, allowing more precise control over its motion.
