If you choose spring shock absorber, you must first know something about the product. Spring shock absorber reduces or eliminates the periodic vibration or instantaneous shock caused by irregular media, wind force, water hammer (or steam hammer) and earthquake through shock absorption, spring stiffness and initial force of spring pre-compression. It can increase the natural vibration frequency of the whole pipeline system and make it leave the forced vibration frequency of the pipeline caused by external interference. The resonance phenomenon of pipeline is avoided and the additional stress caused by vibration of pipeline is reduced.
The selection of the specifications of shock absorber spring depends on the magnitude of the anti-vibration force needed to prevent the vibration of pipeline. If the required anti-vibration force can be calculated by the dynamic analysis of pipeline according to the quality, stiffness of pipeline and the periodic or impulsive force acting on pipeline from outside, the specifications of shock absorber spring should be selected according to the precise value of calculation and the initial force of spring preloading should be determined. Otherwise, the specification of the shock absorber spring can be selected according to the nominal diameter of the pipeline.
Spring shock absorber is a kind of vibration control device sensitive to displacement response. Spring shock absorber is mainly applied to anti-vibration of pipelines and equipment in nuclear power plant, thermal power plant, chemical plant, steel plant, etc. It is often used to control the vibration of piping system caused by fluid vibration, such as fluid pulsation, two-phase flow, high-speed flow and wind vibration.
