In addition to the above parameters affecting the quality of the bellows produced by the Krah machine, the elasticity and deformation of the bellows produced by the Krah machine described below are also important factors affecting the bellows produced by the Krah machine. For different occasions, to facilitate the analysis of the problem, any one of these factors can be used to analyze the quality of the bellows produced by the Krah machine.
Here is the content list:
l Elastic properties
l Residual deformation
The relationship between the displacement and the applied load of the Krah machine metal bellows and other elastic elements on a specified cook is called the Krah machine elastic characteristics, and the displacement and load should be stored within the elastic range of the element material. The Krah machine corrugation The elastic properties of pipe components can be expressed in the form of functional equations, tables, and graphs. The elastic properties of the Krah machine bellows depend on the structure and loading method of various elastic elements.
The elastic characteristics of the Krah machine below components can be linear or non-linear, and non-linear can also be divided into two types: increasing characteristics and decreasing characteristics.
The elastic characteristic of the Krah machine bellows is a main performance index of the bellows and other elastic components of the Krah machine bellows. The Krah machine bellows elastic elements used in instruments and measuring devices are generally designed to have a linear relationship between the output of the element and the measured parameter (load). In this way, the Krah machine bellows can use a simpler transmission and amplifying mechanism to achieve an equal division of the meter.
The residual deformation of the Krah machine wave metal bellows and other elastic elements refers to the displacement of the elements after loading, and the Krah machine bellows after a long period still cannot return to the original position after unloading. The Krah machine bellows produces a residual value of permanent deformation. The residual deformation of the Krah machine bellows components is related to the state of use. When the tension (or compression) displacement gradually increases to a certain displacement value, the residual deformation will increase significantly.
Residual deformation is a parameter to determine the deformation ability of the Krah machine bellows elastic element. For elastic sensitive elements, if a large residual displacement occurs after reaching the rated displacement value, this will affect the measurement accuracy of the instrument. Therefore, a certain limit value is generally given to the residual deformation of the Krah machine bellows. The Krah machine bellows components (such as corrugated expansion joints) are used in engineering, sometimes to obtain a larger displacement, the Krah machine bellows components work in the elastoplastic zone, and there will be larger residual deformations. Such as the Krah machine bellows can meet a certain service life without failure. At this time, the amount of residual deformation is no longer considered.
