What is the internal information of the bellows produced by the Krah machine?

There are many reference items on the performance index of the corrugated pipe produced by the Krah machine. The size of these items determines the superiority of the performance of the corrugated pipe produced by the Krah machine.

 

Here is the content list:

Sensitivity

Effective area

Service life

Tightness

 

Sensitivity

The size of the bellows and other elastic components produced by the Krah machine is called the sensitivity of the component when subjected to a unit load. Stiffness and sensitivity are the main functional parameters of the bellows and other elastic elements produced by the Krah machine, but they are two different ways of expressing the same characteristics of the bellows produced by the Krah machine. For the Krah machine bellows on different occasions, to facilitate the analysis of the problem, any of these parameters can be used.

 

Effective area

For the bellows produced by the Krah machine to realize pressure-to-force or force-to-pressure conversion of elastic components, there is another important functional index that is the effective area. The affective area refers to the size of the concentrated force that the elastic element of the bellows produced by the Krah machine can be converted into a concentrated force under the action of a unit pressure when the displacement of the bellows of the Krah machine is zero.

 

Service life

The elastic components of the bellows produced by the Krah machine have two states when they are under working; one is to work under a certain load and displacement, and to keep the load and displacement constant or rarely change, it is called static work; the other is One use situation is that the Krah machine bellows load and displacement change alternately and periodically. The component is in a cyclic working state. Due to different working conditions, the modes of component damage or failure are also different. The elastic sensitive components of the bellows instrument produced by the Krah machine work within the elastic range. The Krah machine bellows are in a static working state and have a long service life, generally reaching tens of thousands to hundreds of thousands of times. The Krah machine bellows components used in engineering sometimes work in the elastoplastic range or alternating stress state, and the life span is only hundreds of times. The Krah machine bellows components must be given an allowable working life when cyclically working, and specify the number of cycles, time, and frequency.

The rated life of the Krah machine bellows elastic component is the expected service life determined during the component design, and it is required that the component does not allow fatigue, damage, or failure during this period.

 

Tightness

Tightness refers to the performance of the Krah machine bellows components to ensure no leakage under a certain internal and external pressure difference. When the Krah machine bellows components work, the inner cavity is filled with gas or liquid medium, and there is a certain pressure, so the tightness of the Krah machine bellows must be ensured. The Krah machine bellows tightness test methods include air pressure tightness test, leak test, liquid pressure test, and test with soapy water or helium mass spectrometer leak detector.

 

The development and manufacture of the Krah pipe produced by the Krah machine of Eagle Machinery Co., Ltd have a mature production system, and the high-quality product quality has been widely recognized by the industry.
