# Industrial Specification: Pneumatic Actuator

## 1. Technical Definition
A mechanical device that converts compressed air energy into linear or rotary motion to perform work within an industrial system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2-10 bar (0.2-1.0 MPa) at 5-7 bar optimal**. Failure boundary: **15 bar (1.5 MPa) burst pressure for standard aluminum bodies, 0.5 bar (0.05 MPa) minimum for seal lubrication**, Mechanism: **Seal extrusion failure occurs when pressure exceeds 1.5 MPa, causing nitrile rubber seals to extrude into clearances exceeding 0.1 mm, while insufficient pressure below 0.05 MPa prevents lubricant film formation on cylinder walls**.

### 2.1 Analytical Physics Model
Governed by the **Pneumatic Actuator Theoretical Force**:

> **Primary Equation**: $F = P \cdot A \cdot \eta_{eff}$  
> **Engineering Impact**: Calculates real-world pushing/clamping force for rejectors.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Air Pressure | Engineering Constant |
| A | Cylinder Area | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding ISO 8573-1 Class 4 (40 μm particle size, 5 mg/m³ concentration) | 8 | Seal abrasion leading to 0.15 mm³/s air leakage at 6 bar | Install 5 μm absolute filtration with automatic drain at compressor outlet |
| Condensate accumulation in cylinder exceeding 0.1% volume fraction | 8 | Hydraulic lock causing 150% torque overload on piston at 7 bar | Implement coalescing filter with 0.01 μm separation efficiency and heated air dryer maintaining -40°C pressure dew point |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this pneumatic actuator for durability?
**A**: This pneumatic actuator is constructed with aluminum alloy and stainless steel for structural components, plus nitrile rubber and polyurethane for seals, ensuring corrosion resistance and long service life in industrial environments.

### Q: How does the pneumatic actuator convert air pressure into motion?
**A**: Compressed air enters the cylinder barrel, pushing the piston along the piston rod. The piston's movement, guided by end caps and sealed with piston and rod seals, creates precise linear or rotary motion to perform mechanical work.

### Q: What maintenance is required for the pneumatic actuator's BOM components?
**A**: Regular inspection of seals (piston and rod) for wear, lubrication of the piston rod, and checking cylinder barrel and end caps for damage. Using nitrile rubber and polyurethane seals minimizes maintenance in machinery applications.
