# Industrial Specification: Hydraulic Stoppering System

## 1. Technical Definition
A hydraulic-powered system that automatically inserts stoppers into vials within a lyophilization process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-85 bar**. Failure boundary: **Hydraulic pressure exceeding 95 bar causes seal extrusion failure in Buna-N O-rings**, Mechanism: **Seal extrusion failure occurs when hydraulic pressure exceeds the material yield strength of Buna-N (14 MPa), causing permanent deformation and loss of sealing integrity**.

### 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 |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination with particulate matter exceeding ISO 4406 Class 18/16/13 | 8 | Spool valve stiction causing delayed stopper insertion timing | Install dual 3-micron absolute filtration with differential pressure monitoring |
| Thermal expansion mismatch between stainless steel cylinder (17.3 μm/m·K) and aluminum mounting bracket (23.1 μm/m·K) | 8 | Structural misalignment exceeding 0.15 mm causing binding at 65°C | Implement Invar 36 alloy mounting interface with thermal expansion coefficient of 1.2 μm/m·K |
