RDG Series Rotary Drill Rig cylinder is a type of single piston and double acting cylinder. They are used in Different Rotary Drill Rig equipment,which is popular in highway constuction,railway construction,bridge construction and other construction projects.
Features:
1. Small Size, Light weight, High intensity. High intensity,fatigue design,adapative cylinder designed as per loading frequency analysis are applied,and piston rod selection,processing and welding technology are inspected through ultrasonic falt detection. As it is designed for high pressure operation,it is featured in small size ,light weight,high intensity and high reliability.2. Many optional sizes,bore size can be from 40mm to 450mm;3. Fixing type: trunnion or flange or according to customers’ requirements.4. Seal system. Seal rings of NOK from Japan and Parker from USA that can overcome engineering construction conditions. As well as special designed seal system is applied to prevent grit and dust,reduce oil leakage.5. Cylinder body. The thickness of the cylinder body and frange can be changed;the cylinder inner surfaces manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity and better wearing capacity after roll finishing.6. Piston Rod. High frequency quenching followed by hard chrome plating to improve rust proofing and wear and scar resisting performance.7. Safety / buffer functions. Valves with slow stroke,counting balance and emergency close can be installed easily according to requirements. The concealed ones can absorb the impact of buffer device at the end of stroke.
