Pneumatic Rotary Actuator Noise Reduction Guide
Comprehensive solutions for quieter pneumatic system operation
Airflow Optimization
Install exhaust mufflers to dampen high-velocity air noise and use larger-diameter hoses to minimize turbulent pressure drops. Regulating inlet pressure to minimum required levels significantly reduces airflow noise.
Mechanical Damping
Implement anti-vibration mounts between actuator and base. Upgrade to Teflon-coated seals and precision gears to reduce grinding noise. Maintain proper lubrication on all sliding surfaces.
System Design
Isolate actuators from resonant structures and use fiberglass/acoustic foam enclosures. Consider vane actuators for high-noise environments due to their smoother operation.
Preventive Maintenance
Regularly tighten fasteners and replace worn components to prevent noise escalation. Conduct quarterly inspections of all noise-reduction components.
