Title: Small diameter vane damper for seat cover
Long Ji vane dampers and dashpots are used to dampen drives, control speed, and many other applications. The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions.
The damping characteristics can be customized by changing the viscosity of the silicon fluid or by changing the structure of the rotor and stator. Plastic small diameter axis roaty damper life-cycles are typically in excess of 50,000 cycles. The service life may be significantly higher or lower, depending on the application. After extended life cycles the dampers still produce over approx. 80% of their original damping moment.

5. Vane damper Characteristics:
Damper characteristics vary according to the ambient temperature. In general, the damper characteristics become weaker as the temperature increases, and become stronger as the temperature decreases. This is because the viscosity of the oil inside the damper varies according to the temperature. When the temperature returns to normal, the damper characteristics will return to normal as well. The changes in the time it takes for the lid to close are shown in the graph to the right.
