1.Basic Structure and Working Principle of Pneumatic Sleeves
A pneumatic sleeve is a flexible connecting tube used in pneumatic systems, primarily for transmitting compressed air, protecting internal pipelines, and adapting to the reciprocating movement of mechanical equipment. Its typical structure includes:

• Inner tube: Usually made of polyurethane (PU) or nylon, ensuring airtightness for gas transmission.

• Reinforcement layer: Woven from high-strength fibers or metal wires to enhance pressure resistance and tensile strength.

• Outer protection: A wear-resistant rubber or PVC coating to prevent external abrasion and chemical corrosion.

Working principle: When compressed air passes through the pneumatic sleeve, the inner tube expands, while the reinforcement layer restricts excessive expansion to ensure stable air pressure transmission. Meanwhile, the flexible structure allows the equipment to bend freely during movement.

2.Core Technical Advantages of Yuhuan Yangtian Machinery
Yangtian Machinery's YT-QD series pneumatic sleeves have made breakthroughs in the following aspects:

• Multi-layer composite weaving technology: Adopting a hybrid reinforcement of stainless steel wires and aramid fibers, the pressure resistance capacity is increased to 2.0MPa, far exceeding the industry average (1.0MPa).

• Dynamic fatigue testing: Passing 5 million bending tests to ensure long-term reliability in automated production lines.

• Expanded temperature resistance range: Standard models (-30℃~+80℃) and high-temperature models (-50℃~+150℃) to meet the needs of different industrial environments.

3.Typical Application Scenarios

• Automobile manufacturing: Used for protecting the air pipes of welding robots to reduce wear from metal chips.

• Food packaging machinery: Compliant with FDA food-grade standards to avoid grease contamination.

• Semiconductor equipment: Anti-static design, ensuring suitability for cleanroom environments.
