FIELD: heat power engineering. ^ SUBSTANCE: invention can be used in turboplant of power-and-heating plants, thermal and nuclear power stations. Proposed turboplant contains low-, medium-, and high-pressure cylinders with branch pipes and pipelines to deliver and let out steam with intermediate vertical supports connected to cylinders, rotors and feet of housings. Feet of housings rest on movable bearings sliding along longitudinal key joints relative to fixed foundation frames installed on cross-bars of foundation. Pipelines to deliver and let out steam, shells of heaters, regenerative and heating extractions and valves are provided with limited displacement supports. Each limited displacement support is made guide and turnable in critical directions within tolerable limits. Displacement is limited by thrust spring unit, and turning is limited by rolls with locks. Base of turboplant support is made movable with possibility of turning and limited displacement. Base of support is installed inside fixed housing made in form of parallelepiped on rolls with spacer strips in number of two, minimum. Rolls with spacer strips are installed from below relative to movable base and move along rolling guides. Turning of movable base is limited from side by rotating rolls with locks, two locks for each side surface minimum. Longitudinal displacement of base of support is limited by thrust spring unit. ^ EFFECT: improved reliability and increased service life of turboplant and its foundation. ^ 2 cl, 4 dwg |
