# Industrial Specification: Vacuum Pump Head

## 1. Technical Definition
The primary working assembly of a vacuum pump that creates and maintains vacuum pressure.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1e-6 to 1013 mbar absolute pressure**. Failure boundary: **1e-9 mbar ultimate pressure (vapor pressure of pump fluid at 20°C)**, Mechanism: **Vapor pressure limit of working fluid (e.g., perfluoropolyether oil with 1e-9 mbar vapor pressure at 293K) prevents further pressure reduction**.

### 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 |
| :--- | :--- | :--- | :--- |
| Backstreaming of process gases containing condensable vapors | 8 | Oil contamination and viscosity increase to &gt;500 cSt | Integrate cold trap at -80°C upstream with automatic regeneration cycle |
| Rotor-stator clearance erosion from abrasive particles &gt;5μm | 8 | Clearance increase beyond 50μm causing compression ratio drop below 10^4 | Install 0.3μm absolute filter with differential pressure monitoring at 50 mbar |
