# Industrial Specification: Air Supply Regulator

## 1. Technical Definition
A device that controls and maintains consistent air pressure and flow rate to the spraying system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-10 bar (50-1000 kPa)**. Failure boundary: **15 bar (1500 kPa) burst pressure for diaphragm rupture**, Mechanism: **Diaphragm material yield strength exceeded at 15 MPa stress (using ASTM D638 for nitrile rubber)**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 40 μm particle size | 8 | Valve seat erosion causing 0.2 bar/min pressure decay | Install 25 μm absolute filter with differential pressure monitoring |
| Ambient temperature cycling between -20°C to 80°C at 5°C/min rate | 8 | Diaphragm hardening leading to 15% flow reduction | Implement silicone diaphragm with -40°C to 120°C operational range |

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

### Q: What materials are used in this air supply regulator and why?
**A**: This regulator uses brass for corrosion-resistant body components, stainless steel for durable internal parts like the poppet/control valve, and engineering plastics for lightweight, chemical-resistant elements like the adjustment knob. This combination ensures longevity and reliable performance in industrial environments.

### Q: How does this regulator maintain consistent air pressure for spraying systems?
**A**: The regulator uses a diaphragm/piston mechanism that responds to pressure changes, adjusting the poppet/control valve to maintain set pressure. The adjustment knob/spring allows precise calibration, while the pressure gauge provides real-time monitoring, ensuring consistent air flow critical for uniform spray application in manufacturing.

### Q: What maintenance is required for this air supply regulator?
**A**: Regular inspection of the diaphragm/piston for wear, cleaning of the poppet/control valve to prevent clogging, and calibration check using the pressure gauge. The brass and stainless steel construction minimizes corrosion, but periodic lubrication of moving parts and replacement of worn components from the BOM ensures optimal performance.

## 6. Manufacturing Compliance
- ISO 8573-1:2010 (COMPRESSED AIR QUALITY CLASSES)
- ANSI/ASME B40.100-2013 (PRESSURE GAUGES AND GAUGE ATTACHMENTS)
- DIN EN 13445-3:2021 (UNFIRED PRESSURE VESSELS)
