Dampers are categorized into three main types: liquid dampers, gas dampers and electromagnetic dampers. Dampers, are devices that dissipate energy from motion by providing resistance to motion. Dampers play an important role in compensating for the very small friction and air resistance in the pickup pendulum system and improving the frequency response.
Various applications include: spring dampers, hydraulic dampers, impulse dampers, rotary dampers, wind dampers, viscous dampers, damping hinges, damping slides, furniture hardware, cabinet hardware and so on.
Expanded Information:
Dampers are acoustic cloth screens inserted inside sound tubes. These damping elements are used between the output of the receiver and the ear canal and serve to smooth the frequency response.
Hydraulic dampers are mainly used for anti-vibration of pipes and equipment in nuclear power plants, thermal power plants, chemical plants, iron and steel mills, and so on.
Commonly used in the control of shock fluid vibration (such as the main steam door fast closing, safety valve discharge, water hammer, pipe breaking and other shock excitation) and seismic excitation of the pipe system vibration.
Liquid dampers for low amplitude high frequency or high amplitude low frequency vibration can not be effectively controlled, the occasion is appropriate to use the spring damper.
