JZ-HYⅡ型机械液压减震器是一种新型的双作用减震器,它通过两种阻尼弹簧元件:碟簧和硅油的压缩储能来吸收钻具的跳动和震动,它具有良好的可维护性、耐高负荷和较高的使用寿命等优点。同时,该产品具有变刚度特性,在一个减震行程内存在两种刚度,及初始的低刚度和后续的高刚度,可以充分的适应不同地层的需要,给钻头更好的保护。
Model “JZ-HYⅡ” Mechanical and Hydraulic Shock Absorber is a two-action modern shock absorber. It absorb the shimmy and commotion of drill tools by compressing two kinds of damping spring devices ( dished spring and silicone oil ) to store the energy. And it has an advantage of well maintainable, bearing high load and long service life. Meanwhile, the Shock Absorber exist double rigidity in one absorbing stroke (initial low rigidity and subsequent high rigidity).Thus, it can meet a need of distinct layer fully and give a best protection to bits.
