Dc sereis hydraulic buffers is vacuum circuit breaker oil buffers,main used 12kv vacuum circuit breaker, has self regulating function to form an good buffer effect, with the change of impact velocity and weight .Meanwhile the oil buffers piston rod with high hardness and special seals are ensured high service life, special materials and surface treatment makes this product has good anti-corrosion performance, ensuring the normal use in harsh conditions.
With excellent and stable speed and the performance of shock absorption, Its resistance will adjusting automatically when suffering the loaded strike
The axis of stainless steel with high hardness, making the industrial buffers have better impact resistance performance and anti-corrosion performance, ensuring the normal use in harsh conditions.
Features: performance shocks thread’s design is easy to install,, automatic pressure compensation.
Buffer body: performance shocks is high strength hardened steel, surface black finish
The piston rod: high hardness of stainless steel
Piston: wear-resisting for copper
Suitable for working temperature range in - 40 ℃ to + 80℃

Matters needing attention:
1.No painting in tube teeth and the axis, so as not to affect the cooling effect and leak case;
2.Pay attention to the strength of fixed plate and eccentric Angle when assembly.
3.Keep the hydraulic buffers piston rod cleaning, do not have iron foreign body.
4.If the industrial buffers have the cushion cap product, do not unload cushion cap by self for using , this will seriously affect the service life.
