Technical parameters of exhaust bellows

Exhaust bellows' metal bellows tube blanks are made of thin-walled stainless steel welded pipes. The exhaust bellows tube blanks are flexible and have good temperature and pressure resistance. The tube blank of exhaust bellows is suitable for the transportation of various industrial gases such as air, steam, and various fluid media such as water, oil, and medicine.

Carrying load

Various expected load values acting on the exhaust bellows metal bellows and other elastic elements, such as concentrated force F, pressure p, and moment M. When using the exhaust bellows 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 exhaust bellows elastic element is to withstand the internal cavity pressure or the external cavity pressure.

Exhaust bellows The maximum load value or full-scale value that metal bellows and other elastic components are allowed to use under normal working conditions. Exhaust bellows is usually the expected design value or the design value that is revised after actual testing of the exhaust bellows product prototype.

Exhaust bellows specific elastic component products are allowed to exceed the rated load of exhaust bellows without damage, failure, or instability when subjected to an instant or during a test during work. For the elastic sensitive components of exhaust bellows instruments, the overload capacity is generally limited to 125% of the rated load. The exhaust bellows corrugated pipe components used in the project are generally limited to 150% of the rated load. Exhaust bellows according to engineering requirements when a large safety factor is required, the elastic element of exhaust bellows used does not allow any overload, so the load must be less than or equal to the rated load value.

 

Displacement characteristics

The position change of a specific point (free end or center) in exhaust bellows metal bellows and exhaust bellows elastic elements. According to the exhaust bellows motion trajectory, it can be divided into linear displacement and angular displacement. Under the action of external load, the exhaust bellows metal bellows may produce axial displacement, angular displacement, and lateral displacement.

Exhaust bellows metal bellows and exhaust bellows elastic elements caused by the displacement value under the rated load, that is, they are allowed to produce working displacement under normal conditions of use.

All kinds of exhaust bellow elastic elements are allowed to exceed the bearing capacity of the rated displacement at the moment of work or during the test. When exhaust bellows are overloaded and displaced, the elastic components of exhaust bellows should not be damaged, fail, or lose stability. For the elastic sensitive components of the instrument, the overload displacement is generally limited to 125% of the rated displacement. For the exhaust bellows components used in the project, the exhaust bellows should be determined according to the engineering conditions and the degree of safety.

 

Elastic properties

The relationship between the displacement of exhaust bellows metal bellows and other elastic elements of exhaust bellows on a specified cooker and the load of the exhaust bellows is called the elastic characteristic. Exhaust bellows and the displacement and load should be stored in the exhaust bellows elastic bellows of the element material The elastic properties of class components can be expressed in the form of functional equations, tables, and graphs. The elastic characteristics of exhaust bellows depend on the structure and loading method of various elastic elements.
