# Industrial Specification: Spraying Station

## 1. Technical Definition
A specialized station within a finishing line designed for applying coatings, paints, or protective substances onto products or components via spray application.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.3-0.8 MPa (3-8 bar) at nozzle exit**. Failure boundary: **Nozzle pressure exceeds 1.2 MPa (12 bar) causing droplet atomization failure below 20 μm Sauter mean diameter**, Mechanism: **Rayleigh-Plateau instability threshold where surface tension (0.072 N/m for water-based coatings) cannot overcome aerodynamic shear forces at Weber number &gt; 12**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Pneumatic supply pressure fluctuation beyond ±0.05 MPa from setpoint | 8 | Inconsistent film thickness exceeding ±15% specification | Dual-stage pressure regulator with 0.25% accuracy class and 5 μm filter |
| Solvent evaporation cooling dropping nozzle temperature below coating's 15°C minimum application temperature | 8 | Orange peel surface defect with roughness Ra &gt; 2.5 μm | Closed-loop nozzle heating maintaining 25±2°C via PID-controlled cartridge heaters |
