2. Internal factors related to the operation of the spiral air pipe machine and the work of various mechanisms, such as various loads, vibrations, temperatures, etc.;
3. The latent energy accumulated in the parts of the spiral air pipe machine during manufacturing and assembly mainly exists in the form of mechanical energy, thermal energy and chemical energy. When the energy reaches a certain value, the parts will be damaged first, which will be manifested as abrasion, deformation, crack, fatigue, corrosion, etc. The occurrence of damage will also change the structural parameters of the parts of the spiral air pipe machine.

If the structural parameters of the main parts of the spiral air pipe machine reach the limit value after long-term use, and the function output parameters are seriously out of limit, the economy of use will be obviously reduced. At this time, the spiral air pipe machine is in the limit technical state, and it needs to be overhauled or updated in time. The repaired spiral air pipe machine can be put into use only after the technical performance of each part of the spiral air pipe machine reaches the standard through detection.
