How to pay attention to the application of shock absorber
We all know that the usual types of shock absorbers used to be various, and their scope of application is also increasingly wide. Not only in life, vehicles, but also in many industries, it can be said that only vibration can not be separated from shock absorbers. But not all shock absorbers can be used in a certain center, which depends on the environment at that time and so on.
When selecting a shock absorber, we should first understand its characteristics, and then select it in the environment. The characteristics of the shock absorber are that its shape can be designed according to needs, its stiffness can be adjusted, and it can provide greater damping ratio, shear resistance, tensile resistance, compression resistance, and simpler devices than butterfly valves. Its defects are high natural frequency, short service life, and limited operating environment. The temperature of the common operating environment should be controlled between - 30-70 ℃. Some chemical corrosive environments should select shock absorbers of suitable materials for use.
Application range of shock absorber:
1. The vibration source belongs to the vibration isolation and noise control of high frequency rotating mechanical equipment.
For example: for fans, water pumps, generator sets, air conditioning hosts, etc., vibration dampers should be used when the rotating frequency of mechanical equipment should be greater than 1000 revolutions;
2. The impact frequency of stamping equipment should avoid the natural frequency of shock absorber.
Example: punch, die-cutting machine, press, etc;
3. Due to the shock absorption function in all directions, shock absorbers are widely used in automobiles, aerospace and navigation; 4. Other mechanical equipment.
