# Industrial Specification: Chemical Dosing Unit

## 1. Technical Definition
A precision component within an automated CIP/SIP system that accurately measures and dispenses cleaning and sanitizing chemicals.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar (inlet pressure), 0.1-5.0 mL/s (dosing rate), 5-60°C (fluid temperature)**. Failure boundary: **Diaphragm rupture at 8.5 bar differential pressure, gearbox seizure at 0.05 mL/s flow deviation, solenoid burnout at 85°C coil temperature**, Mechanism: **Diaphragm fatigue failure due to cyclic stress exceeding 35 MPa yield strength (Hooke's Law), gear wear from abrasive particle impingement (Hertzian contact stress), coil insulation breakdown at Arrhenius rate doubling per 10°C above 70°C**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cavitation at NPSH &lt; 2.3 m due to vapor pressure differential | 8 | Diaphragm pitting and flow measurement error exceeding ±2% accuracy | Positive displacement pump with 3.5 m NPSH margin and titanium alloy diaphragm (450 MPa tensile strength) |
| Chemical crystallization at saturation ratio &gt; 1.2 (supersaturation) | 8 | Valve seat blockage causing 100% flow restriction within 8 operating cycles | 316L stainless steel flow path with 0.8 μm surface roughness and 15°C minimum temperature maintenance |
