VIBRATION ISOLATION SYSTEM OF NUCLEAR PILE OF SUBMARINE

摘要

FIELD: power engineering.;SUBSTANCE: invention relates to power equipment of submarines. System consists of mounted on a housing on vibration isolation system (5) nuclear pile (1), pipelines (2), housing (4), out-board heat exchanger (3), vibration sensors (6), sensors of dynamic force (10), execution units (9), power amplifiers (8), control systems (7). Execution units compensate the dynamical forces of the pipelines of the emergency system by sensor signals. Vibration isolation system contains the lower and upper supporting plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Bottom support plate is base on which the bottom flanges of springs are rigidly secured. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On facing each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made.;EFFECT: increase in the efficiency of the vibration isolation of the nuclear pile through the pipelines of the emergency cooling system is achieved.;1 cl, 2 dwg
