技术定义与适配语境
典型 进气口 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The air inlet port is a critical component of air bearing pads, designed to precisely control and distribute compressed air into the bearing's porous media or orifice system. It functions as the entry point where regulated air pressure is introduced to generate a thin, stable air film that separates moving surfaces, enabling near-frictionless motion with micron-level precision. This component ensures consistent airflow characteristics essential for maintaining bearing stiffness, load capacity, and vibration damping in precision manufacturing applications.

定义
The air inlet port is a critical component of air bearing pads, designed to precisely control and distribute compressed air into the bearing's porous media or orifice system. It functions as the entry point where regulated air pressure is introduced to generate a thin, stable air film that separates moving surfaces, enabling near-frictionless motion with micron-level precision. This component ensures consistent airflow characteristics essential for maintaining bearing stiffness, load capacity, and vibration damping in precision manufacturing applications.
工作原理
Operates by receiving compressed air from the supply system and directing it through precisely engineered channels into the air bearing's distribution network. The port's geometry and internal features control flow rate, pressure distribution, and turbulence to create a uniform air film between bearing surfaces. Bernoulli's principle and viscous flow dynamics govern the formation of the supporting air cushion that eliminates mechanical contact and reduces friction to near-zero levels.
材料
Typically manufactured from corrosion-resistant materials: 6061-T6 aluminum alloy (anodized)304/316 stainless steelor engineered polymers (PEEKPTFE) for specific applications. Surface finish: Ra ≤ 0.8 μm for metal components. Operating temperature range: -20°C to +120°C for standard versions.
Port Size
1/8" to 1/2" NPT or ISO G threads
Leakage Rate
< 0.1% of nominal flow
Filter Rating
40 μm integrated filtration (optional)
Flow Capacity

常见问题

What is the primary function of an air inlet port in air bearing systems?

The air inlet port precisely regulates and distributes compressed air into the bearing to create a stable air film that separates surfaces, enabling frictionless motion with high precision.

How do I select the correct air inlet port size for my application?

Select based on required airflow (L/min), operating pressure, bearing surface area, and load capacity. Consult manufacturer specifications matching your bearing's orifice count and pressure requirements.

Can air inlet ports be used with different air bearing brands?

While some standardized ports are interchangeable, compatibility depends on thread specifications, pressure ratings, and flow characteristics. Always verify manufacturer specifications before cross-brand usage.
