Damper is a device that can quickly stop the movable part of the instrument in a stable deflection position. In seismic instruments, dampers are used to absorb the natural vibration energy of the vibration system, and their damping force is generally proportional to the speed of the vibration system. There are three main types: liquid damper, gas damper and electromagnetic damper.
Shock absorber plays an important role in compensating small friction and air resistance and improving frequency response in vibration pickup pendulum system. Dampers are widely used in aerospace, aviation, military industry, machinery and other industries. In the storage of gravity shelves, goods are accelerated in the inclined storage chute due to the influence of gravity.
If it is allowed to move freely, the goods will hit the shelf, which may cause damage to the goods, bring security risks to the operators and damage the overall structure of the shelf. Damper plays a very important role in it. Dampers in gravity shelves, also known as reducers, are mainly used to eliminate the gravity acceleration of goods in gravity shelves.
Therefore, the goods can slide smoothly and slowly along the track, eliminating potential safety hazards. Ensure the safety of goods and operators. Among them, damping can be divided into external damping and internal damping.
Extended data:
The damper is just a component, and its damping effect is different when used in different places or different working environments. Dampers are used to reduce vibration; Buffers are used to prevent earthquakes, allow low-speed movement, and lock when the speed or acceleration exceeds the corresponding value, forming a rigid support.
Various applications include: spring damper, hydraulic damper, pulse damper, rotary damper, wind damper, viscous damper, damping hinge, damping slide rail, furniture hardware, cabinet hardware and so on. Hydraulic dampers are mainly suitable for vibration prevention of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants and steel plants.
It is often used to control the pulse vibration of fluid (such as quick closing of main valve, discharge of safety valve, water hammer, pipeline rupture, etc.). ) and pipeline vibration caused by earthquake. Hydraulic damper can not effectively control low-amplitude high-frequency or high-amplitude low-frequency vibration, so spring damper should be used in this situation.
