13.Engineering machinery cylinder series

 Summary:

This kind of durable intermediate-pressure cylinder is designed for small type excavator with ure of  27.5MPa and operating temperature -20°c-- +100°c (for cold area: 40°c--+90°c).

 Features:

HY series products bear the following advantages:

• Small size,light weight and high intensity..... Intensity,fatigue design,adaptive cylinder designed as per loading frequency analysis are applied,and piston rod selection,processing technology,welding technology are inspected through ultrasonic fault detection. As it is designed for high pressure operation, it is featured in small size,light weight,high intensity and high reliability.

•Sealing system... ... seal rings of Parker and Hallite and B+S from Germany that can overcome civil engineering construction conditions,as well as special designed sealing system are applied to prevent grit and dust, reduce oil leakage and obtain optimal piston rod oil film.

•Cylinder body... ... the thickness of cylinder body and flange 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.

•Piston rod... ... high frequency quenchiing followed by nickel chrome plating to improve rust proofing and wear and scar resisting performance.

•Safety/buffer functions... ... valves with slow stroke,conuting 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.
