WENK Pneumatic AC Series Hydraulic Buffer

The AC Series Hydraulic Buffer by WENK Pneumatic is a high-performance damping device designed to absorb and dissipate kinetic energy during mechanical impacts. This precision-engineered buffer effectively reduces shock, vibration, and noise in various industrial applications, protecting equipment and improving operational stability.

Available in multiple models with varying cylinder diameters and stroke lengths (such as AC0806, AC1008, AC1210, AC1412), the AC Series offers tailored solutions for different load and impact requirements. Each model designation indicates specific dimensions, with the first two digits representing cylinder diameter in millimeters and the last two digits indicating stroke length.

The buffer operates on a hydraulic damping principle, where kinetic energy is converted into heat energy through oil flow restriction. It features an adjustable damping mechanism that allows precise control of deceleration rates, ensuring optimal performance across diverse operating conditions.

Constructed with high-quality materials for durability and reliability, the AC Series Hydraulic Buffer finds applications in automation systems, robotics, material handling equipment, and CNC machinery. Its compact design, efficient energy absorption, and adjustable damping make it an essential component for enhancing equipment lifespan and operational safety.

Operating Instructions

Model Selection

Select the appropriate buffer model based on load weight, impact speed, and installation space

Model identification: The four digits after AC represent cylinder diameter (mm) and stroke (mm) respectively. For example, AC0806 indicates 8mm cylinder diameter and 6mm stroke

Installation Preparation

Check if the buffer appearance is intact, without damage or leakage

Confirm the flatness and verticality of the installation position to ensure the buffer can properly absorb impact

Prepare necessary installation tools and accessories

Proper Installation

The buffer should be installed horizontally, with the mounting surface perpendicular to the impact direction, deviation not exceeding ±1°

Fix the buffer with appropriate bolts to ensure secure and reliable installation

Ensure good contact between the buffer's piston rod head and the buffered object to avoid eccentric load

After installation, manually test if the buffer extends and retracts smoothly

Damping Adjustment

After initial installation, set the damping adjustment knob to the middle position

Test the buffering effect under no-load condition, observe the deceleration process of the buffer

Based on actual load and speed, rotate clockwise to increase damping force, counterclockwise to decrease damping force

Conduct load testing after adjustment until ideal buffering effect is achieved

Usage Monitoring

Regularly observe the working status of the buffer to ensure no abnormal noise or leakage

Check if the piston rod surface is damaged or contaminated, keep it clean

Record the buffer's usage frequency and working conditions for subsequent maintenance

Precautions

Load Limitation: Do not exceed the buffer's rated load and impact speed, avoid overloading

Installation Direction: The buffer should be installed horizontally, avoid inversion or excessive tilt angle

Ambient Temperature: Working environment temperature should be within -20°C to 80°C, exceeding the range may affect performance

Avoid Contamination: Keep the piston rod surface clean, avoid dust, oil, or other contaminants entering the buffer

Regular Inspection: Regularly check the buffer's sealing performance and oil condition to ensure normal operation

Professional Maintenance: For repair or replacement of parts, professional personnel should perform the operation

Maintenance

Surface Cleaning: Regularly clean dust and oil from the buffer surface to keep it clean

Piston Rod Protection: Keep the piston rod surface clean, avoid scratches or corrosion

Seal Inspection: Check if the seals are intact and if there is any leakage

Oil Inspection: Regularly check oil quantity and quality, replenish or replace if necessary

Storage Requirements: When not in use for a long time, store in a dry, ventilated environment, avoid direct sunlight and high temperature

Troubleshooting

Poor Buffering Effect: Check if the damping adjustment is appropriate, adjust the damping force

Piston Rod Not Resetting: Check if the reset spring is damaged or if there is air inside

Leakage: Check if the seals are damaged, replace if necessary

Abnormal Noise: Check if foreign objects have entered the buffer or if parts are loose
