Baomain Pneumatic Air Cylinder MAL 25 X 100 User Manual

1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of the Baomain MAL 25 X 100 Pneumatic Air Cylinder. This device is a mechanical component designed to convert compressed air energy into linear motion, commonly used in various automation and industrial applications. Its double-acting, single-rod design ensures controlled movement in both extension and retraction.

2. Safety Information

Always adhere to safety precautions when working with pneumatic systems to prevent injury or damage to equipment.

• Ensure the air supply is disconnected and pressure is relieved before performing any installation, maintenance, or troubleshooting.
• Wear appropriate personal protective equipment (PPE), including eye protection, when working with compressed air.
• Do not exceed the maximum operating pressure specified for the cylinder.
• Ensure all connections are secure and leak-free to prevent sudden pressure loss or component failure.
• Avoid placing hands or body parts in the path of the moving rod during operation.
• Only use clean, dry, and filtered compressed air.

3. Product Overview

The Baomain MAL 25 X 100 is a compact, double-acting pneumatic cylinder constructed from durable stainless steel and aluminum alloy. It features a single rod design for linear actuation.

Key components include the cylinder barrel, piston, piston rod, end caps, and air ports for compressed air input and exhaust.

5. Setup and Installation

Proper installation is crucial for the cylinder's performance and longevity.

1. Mounting: Securely mount the cylinder using appropriate brackets or mounting points. Refer to Figure 3.2 for dimensional details and mounting thread specifications (M22x1.25 at the body end).
2. Air Connections: Connect the compressed air lines to the 1/8" PT ports on the cylinder. Ensure connections are tight and sealed to prevent leaks. Use thread sealant if necessary.
3. Rod Connection: Attach the load or mechanism to the threaded piston rod (M10x1.25). Ensure the load is aligned with the cylinder's axis of motion to prevent side loading, which can damage the rod and seals.
4. Air Supply: Connect the cylinder to a clean, dry, and regulated compressed air supply. An air filter, regulator, and lubricator (FRL unit) are recommended for optimal performance and lifespan.
5. Initial Test: With the air supply at a low pressure, slowly cycle the cylinder a few times to check for smooth operation and any leaks before applying full operating pressure.

6. Operating Instructions

The MAL 25 X 100 is a double-acting cylinder, meaning air pressure is used to extend and retract the piston rod.

• Extension: To extend the rod, apply compressed air to the rear port (opposite the rod end) and allow air to exhaust from the front port (rod end).
• Retraction: To retract the rod, apply compressed air to the front port (rod end) and allow air to exhaust from the rear port.
• Control: The speed of extension and retraction can be controlled by flow control valves installed in the air lines.
• Pressure: Operate the cylinder within its specified maximum pressure of 1 MPa (145 PSI).

7. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your pneumatic cylinder.

• Air Quality: Ensure the compressed air supply is clean, dry, and free of contaminants. Use an air filter to remove particulates and a dryer to remove moisture.
• Lubrication: If not using an FRL unit with an auto-lubricator, periodically apply a small amount of pneumatic-grade lubricant to the air supply. Avoid over-lubrication.
• Leak Checks: Regularly inspect all air connections and the cylinder body for air leaks. Leaks can reduce efficiency and indicate seal wear.
• Rod Inspection: Check the piston rod for any signs of damage, scratches, or corrosion. A damaged rod can lead to seal failure. Keep the rod clean.
• Mounting Security: Periodically check that the cylinder's mounting bolts are tight and secure.
