Hydraulic Cylinders for CSP Drives

Hydraulic cylinder requirements in solar application• Harsh environmental conditions (sun, sand, extreme temperature),

the steeples operation mode and the need to control the movement easily

• Highest requirements with regard to toughness and durability

• Highest quality and compliance with all statutory regulations are essential

• Friction-optimised cylinders constitute the basis for a well-matched control system

WEBER - HYDRAULIK COMPANIES March, 2011Page 11

Hydraulic Cylinder for CSP Drives

• Piston head– reinforced design

• Ball bearings– maintenance free, length adjustment

• Piston rod– High performance corrosion resistance (diff. Layer)– Tensile strength 580 N/mm²– Hardened rod resist dust abrasion

• Sealing system for pressure peaks up to 600bar– Rod sealing: Primary + Secondary seal => low leakage– Polyurethane wiper => UV - resistant– Piston seal: stick-slip-free

• Valve block with counterbalance valves– Adjustable pressure limits up to 300 bar– Screwed pipe => best accessibility and change – Optional connectors for measurement

• Painting– Corrosion- and UV - resistant – Excellent adhesion and abrasion resistance

• Optional: oil filled shipment
