Отклик стационарной газотурбинной установки с ротором в подшипниках скольжения на сейсмическое воздействие

Отклик стационарной газотурбинной установки с ротором в подшипниках скольжения на сейсмическое воздействие

Abstract

The authors investigated the response to an earthquake of magnitude up to 9 points for the two schemes of stationary gas turbine unit (GTU): with a heavy rotor in full plain bearings and a flexible rotor in journal bearings with self-aligning pads, and shoe-type bearings. The orbits of the rotor and the deformation of body parts in stationary and during the seismic impact are determined, that allowed to estimate the change of clearances in the gas-dynamic channel and bearings, and make a conclusion for GTU on capacity for work under seismic impacts.

Исследован отклик на землетрясение силой до 9 баллов для двух схем стационарной газотурбинной установки (ГТУ): с тяжелым ротором в полных подшипниках скольжения и с гибким ротором в подшипниках скольжения с самоустанавливающимися колодками и сегментных подшипниках. Определены орбиты вращения ротора и деформации корпусных деталей при стационарном вращении и сейсмическом воздействии, что позволило оценить изменение зазоров в газодинамическом тракте и подшипниках и сделать вывод о работоспособности ГТУ при сейсмическом воздействии.
