Thermal Stress State of the Parts of Quasi-isothermal Long-stroke Low Flow Stages in Reciprocating Compressors

For low flow long-stroke compressor aggregates with particular regime and structural parameters static analysis of thermal stresses state is carried out. Moreover, simultaneous influence of thermal and mechanical effect is taken into consideration. Boundary conditions for calculation are obtained while implementing the developed mathematical model. Thermal stress comparison of the stages with intense and soft cooling is given.
