# Industrial Specification: Hydraulic Adjustment System

## 1. Technical Definition
A hydraulic system used to adjust the discharge opening of a cone crusher for product size control.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa hydraulic pressure, 0.1-2.0 mm/s piston velocity, 40-80°C fluid temperature**. Failure boundary: **Hydraulic pressure exceeding 42 MPa causes seal extrusion failure; piston velocity below 0.05 mm/s results in stick-slip motion; fluid temperature above 95°C degrades ISO VG 46 hydraulic fluid viscosity below 10 cSt**, Mechanism: **Cavitation at pump inlet when NPSHa &lt; 0.5 m; thermal expansion mismatch between steel piston (α=12×10⁻⁶/°C) and bronze bushing (α=18×10⁻⁶/°C) causing binding at ΔT&gt;40°C; elastomer seal hardening per Arrhenius equation with activation energy 80 kJ/mol at T&gt;90°C**.

### 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.
