Abstract |
The design features of diaphragm compressors are discussed in this article. For preventing the formation of local stresses in certain areas of the diaphragm, it is recommended to use thin sheet stainless
steel of the transition class. A comparative analysis is made of two batches of steel tape, differing in the
value of the saturation magnetic induction, which is identical to the content of the martensite phase in
the structure of the material before the final cycle of cold plastic deformation. The results of the study of
the influence of the deformation temperature (20 – 300 ºС) on the change in mechanical properties (σb,
σ0.2, δ) revealed a different tendency to embrittlement of the material of the tapes for these batches. For
increasing the operational reliability of the compressor's diaphragm elements, it is recommended to use
a material, the structure of which contains a certain amount of work-hardened retained austenite. This
makes it possible to undergo additional martensitic transformation under the action of peak loads in local
areas and increases the structural strength of corrosion-resistant steel for the manufacture of a compressor diaphragm. |
