ALJ‑5007: One Solution to Conquer High‑CG CT and Floor Resonance

Upload time：2025-06-04 Publisher：安立静

Conditions & Challenges

Equipment Parameters
CT scanner gantry, self-weight 1250 kg, dimensions 1936×834×1818 mm, installed on the second floor.
Core Pain Points
Obvious low‑frequency vibration during operation. Due to the high center of gravity, strong vibrations are transmitted to the floors above and below, affecting neighbor relations and posing a potential threat to the structural safety of the floor slab.

Solution

Recommended Model
To address low‑frequency vibration and high center of gravity, the ALJ‑5007 dedicated isolator is recommended. Designed for heavy precision equipment, it delivers superior vibration isolation while providing stable support.
Key Advantages
Structural Innovation
Triple protection: “top/bottom anti‑slip rubber pads + non‑linear air spring + composite damper”.
Air Spring Technology
One‑piece vulcanized natural rubber – thick, resilient. Compressed air achieves an extremely low natural frequency, isolating low‑frequency vibration at the source.
Large‑Diameter Air Chamber
Sufficiently large air chamber ensures safe load capacity and stable operation.
Composite Damping System
High‑viscosity damping oil in the damper cylinder delivers a high damping ratio, rapidly attenuating amplitude and preventing resonance amplification.
Performance
Multi‑Dimensional Stability
Effectively reduces vertical vibration while providing excellent lateral stability – solving the sway problem of high‑center‑of‑gravity equipment.
Noise Reduction & Floor Protection
Significantly cuts equipment noise and structure‑borne sound, effectively protecting floor slab integrity and extending the service life of both the building and the equipment.
Quality Assurance
Each isolator undergoes high‑pressure air tightness and durability fatigue tests before leaving the factory, ensuring long‑lasting performance under sustained high‑frequency operating conditions.
