Original Contitech FD330-22 Double Convoluted Air Bags G1/4 Air Spring For Industrial Textile Machinery

The Core Role of Gas Springs in Textile Looms

Textile looms, especially high-speed looms, air-jet looms, and rapier looms, generate severe vibration and impact during operation. These vibrations can cause a series of problems:

Impact on fabric quality: Vibration can lead to uneven tension in the weft and warp threads, resulting in defects (such as weft skew and warp breakage), and reducing fabric quality.

Impair machine precision: Long-term vibration can loosen mechanical parts, accelerate wear, and affect the dynamic accuracy and lifespan of the equipment.

Generate loud noise: Vibration is one of the main sources of high noise levels in textile workshops.

Impact on building structures: Strong vibrations can be transmitted through the foundation, potentially affecting the factory structure and the operation of other precision equipment.

The FD330-22 air spring is designed to address these issues:

1. Excellent vibration isolation and damping
Principle: An air spring is an elastic element supported by compressed air. Its natural frequency is very low (typically as low as 2-4 Hz), making it very effective in isolating high-frequency vibrations.

Effects:

Machine Protection: Isolates the loom body from the foundation, absorbing and cushioning most operational shocks, ensuring stable operation and extending the life of key components such as the main frame and main shaft.

Quality Assurance: The stable machine provides a stable environment for the weaving process, ensuring precise interweaving of warp and weft yarns, directly improving fabric quality.

Noise Reduction: Structure-borne noise is reduced, significantly lowering noise levels throughout the entire workshop.

2. Precise Height and Level Control
Principle: By adding a height valve or electronic control system, the air spring can become an active adjustment system.

Effects:

Automatic Leveling: Regardless of changes in the loom load (for example, from small to large roll diameter), the height valve automatically inflates or deflates air, maintaining the loom frame at the preset height and ensuring the machine is level. This is crucial for tension-sensitive warp systems.

Adapts to Uneven Ground: By individually adjusting the air pressure at each support point, the entire massive loom remains perfectly level, even on slightly uneven foundations.

3. Excellent Fatigue Resistance and Long Life
Air springs offer a large travel range and far superior fatigue resistance to traditional rubber pads or metal springs. They can withstand the hundreds of millions of high-speed cycles of textile machinery, providing long-term, stable vibration reduction.
