Background
In industrial production and life, displacement changes of parts such as boiler bodies of power stations, suspended parts of steam, water, smoke, air pipes, combustors and the like of power plants and places needing the supports in petroleum and chemical industries often occur due to the influence of external factors, the influence of the displacement changes cannot be solved by adopting fixed supports or suspension, on the contrary, normal changes of the parts are influenced, adverse stress of the parts cannot be timely solved, and production safety is influenced. Taking the combustor pipe system as an example, when the thermal displacement of a certain hoisting point in the pipe system is larger than 12mm, the pipe system is easy to generate dangerous bending stress and unfavorable stress transfer when a fixed support is adopted, the normal operation of the whole pipe system is affected and even damaged, and great hidden danger is brought to production and operation.
In order to reduce the displacement stress of the components during use, a constant force support hanger is generally selected to support the components, and the pipes and equipment supported by the constant force support hanger can provide constant support force during displacement so as to avoid dangerous bending stress and unfavorable stress transfer of the pipe system.
In the use of the existing constant force support and hanger, a spring type constant force support and hanger is mainly used. The spring type constant force support hanger is designed according to a moment balance principle, and takes a constant force spring as a main component. It relies on a delicate geometric design to balance the load moment and the spring moment all the time during operation to maintain a constant bearing force, eliminating or reducing additional stresses on the pipe or equipment. The specified load dispersion (including friction) in the full stroke is less than or equal to 6 percent; the deviation between the average value of the load in the whole stroke and the designed load is less than or equal to 2 percent. In the actual production process of the pipeline and the equipment using the spring type constant force support hanger, when the pipeline or the equipment generates displacement, as long as the pipeline or the equipment is in the preselected load displacement, no matter how large the displacement change is, the pipeline or the equipment can always obtain constant supporting force through the constant force spring support, and new additional pressure cannot be brought to the pipeline or the equipment, so that the safety accident of the major equipment can be avoided.
The spring type constant force support hanger can not adjust the magnitude of the constant force, the effective constant force stroke is very small, and only constant supporting force can be provided in a small displacement range.
