slide phone damper

Product Usage Apply to slide phone and other similar function products. With the damper, it reduces the noise, advances the products level, and expresses the products humanity concept. Basic Principles The torque made by the damping oil to the rotating parts cohesion effect is the resistance. The resistance is decided by the viscosity and contact area of damping oil. Higher viscosity,bigger contact area, the resistance is bigger. Or, the resistance is smaller. Temperature Characteristics Resistance of the damper varies according to the ambient temperature.Since the temperature effects the sealing damping oil fluidity.If the temperature is higher, the fluidity is higher, and the resistance is lower, and vice versa.The suitable temperature range is -20°C—80°C. Speed Characteristics Under common condition,the resistance made by the oil to the rotating parts cohesion effect will be higher if the rotating speed is higher, and vice versa. Resistance and Testing In the production testing under normal 27.5°C,put the products on the axis rotating in a speed of 36r/min. And the resistance in the 3rd rotate is looked as the standard one.
