Hydraulic Damper

Hydraulic damper is a damping device that uses special valve control to control the movement of the hydraulic cylinder piston to suppress the impact of periodic loads or impact loads on pipelines and equipment. Its performance characteristics can be summarized in four words: "hardness and softness": when the pipeline is in normal working condition, it can adapt to the slow movement of the pipeline caused by changes in the cold and heat of the medium and produce almost no damping on the pipeline, which is the so-called " "Soft"; under special accident conditions (such as earthquakes, water hammer, steam hammer, safety valve exhaust, broken pipes, etc.), when the pipeline is subject to an instant impact, the hydraulic damper becomes a nearly rigid mechanism to support the pipeline, and the impact load is Vibration energy can be quickly absorbed and transmitted, thereby reducing the impact amplitude of the pipeline and achieving buffering and earthquake resistance requirements.
