DESCRIPTION

The constant-force spring used in the constant-force spring support and suspension frame is closely coiled in the free state, and its H-arc high (mm) outer end is fixed (riveted) on a working end. When the spring coil is pulled to the right, it produces a working force opposite to the pulling direction. The elastic modulus (kgf / mm2) plays a supporting role and is in tension state. When the spring is pulled away from the free state to the tension constant force, it is contrary to the above process. It is a deformation zone transiting from the force state and produces continuous pressure. Because of the deformation process from the flat section to the arc section of the constant force spring suspension frame, and the original curvature of the compact coil is basically the same when the deformation is near completion, the restoring force produced by the deformation, that is, a considerable critical force, must appear.

Constant force spring support and hanger standard NBT47038-2013 (hereinafter referred to as constant force support and hanger) is designed according to the principle of moment balance. The principle of lever is used to realize that when the pipe expands and produces displacement, the constant force spring hanger is applied to the pipe with the force change rate of less than 5%, so as to support or suspend the pipe. Under the allowable load displacement, the load torque and spring torque are always balanced. For pipes and equipment supported by constant crane, constant supporting force can be provided when displacement occurs, so additional stress will not be brought to the piping equipment. Constant crane is generally used to reduce displacement stress in places such as power plant boiler body, power plant steam, water, smoke, air duct and burner suspension parts, as well as in petroleum and chemical industries need such support. When the thermal displacement of a suspension point in the pipeline system is greater than 12 mm, the constant suspension should be selected to support the suspension so as to avoid dangerous bending stress and unfavorable stress transfer in the pipeline system. Because of its simple and mature manufacturing process, stable performance and good economy, the spring and its components have been widely used in China for a long time.
