Note:

1The marked torque is measured under conditions of temperature23+/-2℃, humidity80%with standard load falling slowly at a rate of one degree per second.15The data can be customized by changing the viscosity of the damper oil.

__Damper characteristics____A. Temperature characteristics:__

__The torque generated by the damper will change under the influence of ambient temperature. This is because changes in temperature will affect the viscosity of the damping oil, causing torque output to decrease with rising temperatures; and increase with decreasing temperatures. When the temperature returns to normal, torque also returns to its original value.__

__B. Speed characteristics:____The torque of the damper will also change when using different rotational speeds.____Generally, as rotational speed increases, torque also increases; as rotational speed decreases, torque decreases.__

__Additionally, starting torque differs from standard torque.__

__5.____Usage method for pressure-type dampers:____A.____The closed position is the cushioning termination position; at this angle, torque output is maximized and serves as a reference for cushioning termination installation.____B.____The angle between the flat position for mounting on the rotating shaft and that on the other side of the body is__90°.The maximum rotation angle of the buffer is110°, exceeding this angle may damage the buffer itself.Please design an external stop positioning mechanism during design.D. Please minimize gaps between rotating shaft holes and mating parts; if there are gaps, it will affect rotation buffering speed.另启动时扭矩与标准扭矩也不同。

5.压力式阻尼器的使用方法：

A.闭合位置为缓冲终止位置，缓冲器在此角度时扭矩输出最大，并以此位置为缓冲终止安装基准。

B.旋转轴扁位安装基准与本体另外一侧定位扁位的夹角为90°。

C.缓冲器的旋转角度最大为110°，超过角度旋转时会损坏缓冲器本身，设计时请在外部设计停止定位机构

D.旋转轴孔和配合部件的间隙请尽量减小，如果存在间隙，旋转缓冲的速度会受到影响。
