Vacuum Bellows Manufacturers Explain Product Load-bearing
Technology
There is a certain critical point for the bearing capacity of anything. When the critical point is exceeded, failure may occur, so the load capacity of the vacuum bellows also has a critical point. Today, vacuum bellows manufacturers explained the product load-bearing technology.
Various expected load values acting on the vacuum bellows and other elastic elements, such as concentrated force F, pressure p and moment M, etc. When the vacuum bellows-type elastic element is used, in addition to the given load value, the action direction and position of the load must also be given. For pressure loads, it is also necessary to state whether the elastic element is subjected to internal or external cavity pressure.
The maximum load value or full-scale value allowed for vacuum bellows and other elastic components under normal operating conditions. It is usually the expected design value, or the modified design value after actual testing of the product prototype.
The bearing capacity of a specific elastic element product when it is subjected to transients or during testing is allowed to exceed the rated load without damage, failure and instability. For instrument elastic sensitive components, the overload capacity is generally limited to 125% of the rated load. Bellows components used in engineering are generally limited to 150% of the rated load. According to engineering requirements, when a large safety factor is required, the provisions of the used elastic elements do not allow any overload, so the load must be less than or equal to the rated load value.
