# Industrial Specification: Delivery System

## 1. Technical Definition
The hydraulic and mechanical assembly responsible for pumping and distributing concrete through the boom pipeline.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 bar hydraulic pressure, 0.5-2.5 m³/min concrete flow rate**. Failure boundary: **Hydraulic pressure exceeding 42 bar causes seal extrusion, concrete flow below 0.3 m³/min causes pipeline blockage**, Mechanism: **Cavitation at pump inlet when NPSHa &lt; NPSHr by 0.5 bar, causing vapor bubble collapse and impeller pitting (Bernoulli principle)**.

### 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 |
| :--- | :--- | :--- | :--- |
| Contaminant particle &gt;50μm in hydraulic fluid | 8 | Servo valve spool seizure at 0.01mm clearance | Install 10μm absolute filtration with differential pressure monitoring at 3 bar |
| Concrete slump variation beyond 150±20mm specification | 8 | Pipeline pressure surge to 38+ bar causing hose coupling separation | Implement real-time rheology monitoring with automated water reducer injection |

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

### Q: What materials are used in the delivery system for durability?
**A**: The system uses high-strength alloy steel for structural components, wear-resistant hardened steel for high-friction areas, and specialized rubber seals to prevent leaks and maintain pressure integrity.

### Q: How does the hydraulic system control concrete flow?
**A**: Hydraulic control valves regulate pressure and direction, while hydraulic pumping cylinders provide the force needed to pump concrete through the delivery pipeline with consistent flow and minimal pulsation.

### Q: What maintenance does the S-valve assembly require?
**A**: The S-valve assembly requires regular inspection of wear surfaces, lubrication of moving parts, and replacement of seals to ensure smooth concrete flow switching and prevent blockages in the delivery system.

## 6. Manufacturing Compliance
