It is considered that link wear speed on seal surface is proportional to the contacting pressure. The impacting of valve disk on valve seat is the important reason of abrasive wear, and the relative motion of disk is a main reason for errosion wear of pump valve. The cycles per minute is an important factor to influence the valve motion and the impact force.

结果表明，泵阀密封面联接磨损的磨损速度与密封面上的接触比压成正比，泵的冲次是影响阀盘运动规律及对阀座产生冲击的重要因素，泵阀产生磨粒磨损和疲劳磨损的主要原因是泥浆、阀盘和阀座的冲击，冲蚀磨损导致泵阀的刺蚀。

With a double-thread screw ,the nut motion is two pitches ,and, in general,the motion of the nut per screw rotation will be the lead(the pitch times the number of threads).

对于双头螺柱，螺母移动两倍的螺距，通常螺栓旋转一圈，螺母移动的距离为导程。

The rebounding damping technology, that the function in the same kinds of products sold in the market are not in common, means when you pull the drawer out to the bottom, it will has a process of soft closing and rebound, which can reduce the noise made by the things loaded in the drawer in efficiency. Moreover, because of the variable damping technology, which help to lessen the force of of the inertia made by the motion of the box when open or close it, and it will extend the useful life of the cabinet effectively. Therefore, it proved that the two-way slow motion cabinet have a longer useful life than the single soft-closing drawer system. And that is the reason why GRASS HOPPER is so popular in many countries all over the world.

反弹阻尼技术就是当你的橱柜抽屉拉到尽头时，有一个轻微的缓冲反弹过程，这样就减小了抽屉里面的装载物的碰撞声音，能达到更加实际意义上的静音，同时由于具备这种功能，在开合抽屉时就大大减小了由于抽屉的运动惯性对柜体产生的破坏力，这样就有效的延长了橱柜的使用寿命；所以使用双缓冲抽屉的橱柜比使用单缓冲抽屉的橱柜寿命明显延长，而市场上还没有具备这种功能的同类产品。
