What are the benefits of damping pneumatic butterfly valves?
Damping is one of the three basic elements for controlling oscillation. However, its performance parameters are difficult to test and its damping effect is difficult to predict. Therefore, in general, the first way to stop the vibration control is to add mass, change stiffness, add vibration isolators or dynamic vibration absorbers, while in some special places, the damping method is required. For example, some thin plate shock absorbers, which make people feel helpless, can obtain satisfactory results by using damping methods.
Damping damper has the following benefits: it can suppress the oscillation peak value at the resonance frequency; Reduce the transmission of oscillation along the structure; Reduce construction noise. It is worth pointing out that damping is the most useful for suppressing oscillations in the resonant region, but it is less effective in the non resonant region.
The damping tension spring has two advantages of the low frequency of the tension spring shock absorber and the large damping of the shock absorber. By separating the advantages of the two points, the phenomenon of amplitude surge when the tension spring shock absorber resonates is eliminated, and the problem of high natural frequency of the shock absorber is solved. It is an active and passive vibration isolation aspiration commodity. The ZD damping tension spring shock absorber has a wide load range and strong compliance. It can simultaneously produce significant effects on active vibration isolation, passive vibration isolation and impact vibration isolation. It is a multi-functional universal vibration isolation commodity and is suitable for the operating environment at - 20 ° C-80 ° C. Its natural frequency within the normal operating load range is between 1.5Hz and 4.9Hz, and the damping ratio is 0.065. It is an air conditioner, constant temperature equipment, fan Cooling tower, refrigeration unit, compressor, water pump and other airborne equipment are aspiring vibration reduction products.
Damping vibration reduction is mainly completed by using the inherent characteristics of damping data and the reasonable design of damping structure. Damping data is a new type of special data developed in the past decade, which has gained increasing effect in many fields. It is a kind of polymer data, which has high damping characteristics when changing modes, that is, it can consume energy when deforming, and can stop the peak value of structural oscillation in a wide frequency range.
Damping data can be divided into two categories, one is damping plate similar to plate, and the other is damping coating similar to rubber.
