Background
The large-tonnage damper generally refers to large-scale damping equipment with rated load of 3000KN and 8000KN, and is mainly applied to large-scale equipment or super pipelines to prevent the equipment or the pipelines from being damaged due to interference force generated by earthquakes or accident working conditions. The working principle of the large-tonnage damper is that the moving speed of a piston rod is controlled by means of a functional valve with a special structure, so that the influence of periodic load or impact load on a pipeline or equipment is restrained. When an accident condition occurs, the damper becomes an approximately rigid structural member to absorb the impact force and reduce the damage caused by the impact. Under the normal operation condition, the design of the damper allows the damper to freely operate, and almost has no resistance action, so that the requirements of equipment and pipelines on thermal expansion and cold contraction are met.
Based on the functional characteristics, the functional characteristic parameters of the damper are periodically verified during the service period, and the verified characteristic parameters comprise locking speed, releasing speed, low-speed friction resistance and the like. The large-tonnage damper is large in size and weight, and the whole assembly and disassembly is inconvenient to test, so that the large-tonnage damper is basically developed into a structural form with an external functional valve and convenient assembly and disassembly through continuous technical evolution.
