Product Description
1.Product usage:
Apply to Auto Sound clamshell, sitting WC pan clamshell, hospital bed and other eletric clamshell products. It reduces the noise during the using process of the above products, advances the products leval, and expresses the products humanity concept.
2.Basic principles:
The torque made by the damping oil to the rotating parts cohesion effect is the resistance. The value of the resistance is decided by the viscosity and contact area is bigger, the resistance is bigger, and vice versa.
3.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.
4.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.
5.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. Commonly, the resistance can be adjusted from 30g to 200g.
