description: In accordance with the following graduate qualification work of the bachelor, the average pressure of a steam condensing turbine with a capacity of 790 MW was calculated. The turbine K-800-240-5 LMZ was used as a prototype.
During this work, the choice and calculations of the PTU thermal scheme, gas-dynamic calculations of the flow section of the central automated system on the average request were made using a software package in order to obtain a flow section that meets the specified requirements.
In accordance with the results of the gas dynamic calculation, the velocity triangles of the turbine stage under consideration are constructed and the blade is modeled.
Based on the above, a longitudinal section drawing of a medium pressure cylinder is being developed. Next, the static strength of the working blade of the last stage of the MPC and the corresponding disk artificially isolated from the solid-forged rotor are calculated, followed by the choice of material. After that, the calculation of the natural frequencies of the blade and the rotor of the MPC is carried out, the results of which are used to construct the corresponding vibration diagrams.
