The quality of the elastic elements of the bellows produced by the Krah machine depends on the material properties of the elastic materials used. Therefore, according to the parameters used for the elastic components of the corrugated pipe produced by the Krah machine, the elastic materials with appropriate performance parameters can be selected to process and manufacture qualified Krah machine corrugated pipe components.
Here is the content list:
l Carrying load
l Displacement characteristics
Various expected load values acting on the Krah machine's metal bellows and other elastic components, such as concentrated force F, pressure p, and moment M. When using the Krah machine metal bellows elastic element, in addition to the given load value, the direction and position of the load must also be given. For the pressure load, it should also be stated that the Krah machine elastic element is subjected to internal cavity pressure or external cavity pressure.
The maximum load value or full-scale value allowed by the Krah machine metal bellows and other elastic components under normal working conditions. The Krah machine is usually the expected design value or the design value that is revised after the actual testing of the product prototype.
Specifically, the Krah machine's metal bellows elastic component products are allowed to exceed the rated load without damage, failure, or instability when subjected to an instant or during a test during work. The Krah machine metal bellows generally limit the overload capacity to 125% of the rated load for the elastic sensitive components of the instrument. The Krah machine metal bellows components used in the project are generally limited to 150% of the rated load. According to engineering requirements, when a large safety factor is required, the Krah machine elastic element used does not allow any overload, so the load must be less than or equal to the rated load value.
The Krah machine changes the position of a specific point (free end or center) in the metal bellows and elastic element. According to its trajectory, it can be divided into linear displacement and angular displacement. Under the action of external load, the Krah machine metal bellows may produce axial displacement, angular displacement, and lateral displacement.
The displacement value of the Krah machine metal bellows and elastic elements caused by the rated load, that is, they are allowed to produce working displacement under normal conditions of use.
All kinds of the Krah machine's elastic components are allowed to exceed the capacity of the rated displacement at the moment of work or during the test. In the event of overload displacement, the Krah machine's elastic components should not be damaged, failed, instability, etc. For the sensitive components of the Krah machine, the overload displacement is generally limited to 125% of the rated displacement. The bellow components used in the project should be determined according to the engineering conditions and the degree of safety.
