Hydraulic Cylinders
WEBER - HYDRAULIK COMPANIES March, 2011Page 10
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
