Description
Technical field
The present invention relates to nuclear power fields, are set more specifically to a kind of reactor-loop and available for reactor master
Standby shock-absorption support device.
Background technology
In reactor-loop, pressure vessel is the centre of location, and a closed circuit is formed by pipeline with main pump.One
Temperature can be in room temperature and 320 DEG C or so variations when each main equipment in circuit plays heap, shutdown, therefore reactor pressure vessel can be because of temperature
Variation generates thermal expansion, and main pump not only itself generates thermal expansion, to be also superimposed pipeline thermal stretching and thermal walking occurs.
Because temperature span is larger, reactor heat displacement amount often up to tens of milliseconds, if the supporting of all devices set
Be calculated as fixed bearing, be entirely limited these thermal expansions and thermal walking, the thermal stress that equipment and branch are born can be more than allowable stress and
It destroys.
Some land large commercial reactor-loop main pumps mostly employ the branch of one group of both-end spherical oscillating bearing

Degree ensures ozzle docking.Rolling bearing can realize that horizontal, longitudinal direction rolls translation using double-layer structure, and release primary Ioops are superimposed
Thermal walking on to main pump.
Which shortcoming of above-mentioned existing product structure or technology：
1. land raft main pump is influenced by primary Ioops system characteristic of expanding with heat and contract with cold, it is necessary to be discharged larger thermal walking, be propped up
Hold the support pattern using connecting rod supporting leg and damping.Connecting rod supporting leg and damping support both ends are this using spherical joint bearing
Oscillating bearing allows along the unrestricted rotation of axis pin axis, while allows along other rotations being respectively limited to amplitude.
Due to connecting rod unstability and the multiple degrees of freedom of spherical joint bearing, supporting allows evaporator larger in conduit axis
Displacement, and allow limited displacement occurs along remaining direction.Connecting rod outrigger support has multidirectional degree of freedom, it is necessary to main pipeline
Stable supporting system is formed together.
Under terrestrial environment, main pump for a long time only by vertical direction external applied load, is laterally protected in normal conditions without apparent load
Hold stationary state.It is only divided into accident conditions and receives lateral impact effect, generate the of short duration inertia force directly proportional to itself.
Since equipment center is misaligned with supporting-point, inertia force acts on supporting member and generates torque.Main pump under terrestrial environment
Long-time remains stationary, connecting rod outrigger support are subjected only to vertical load.In earthquake, LOCA (loss-of-coolant
Accident, coolant loss accident loss of-coolant accident (LOCA)) etc. under accident conditionses, connecting rod supporting leg can not effectively transfer lateral force, torque
Etc. load, it is necessary to carry of short duration lateral impact load by damper.
2. land heap-type primary Ioops coolant system is mounted in concrete foundation, concrete itself possesses certain damping
Effect.Main pump is supported without apparent shock-damping structure.
Under marine environment, reactor has been superimposed outside a long-standing periodicity on the basis of above-mentioned load and has carried
Lotus.The external applied load is caused rolling, pitching, heel, trim and the heaving of reactor foundation structure by Periods.
And the durations in marine environment are waved, under tilt condition, each main equipment can generate larger in the horizontal direction
Lasting alternation inertial load, size is directly proportional to equipment quality.Main pump must discharge system heat expansion amount, the supporting leg of land type
Supporting has multidirectional degree of freedom, can not provide effective lateral-supporting.
In main equipment, connecting the main pipeline of each equipment will be subject to compared with large cyclic the periodicity alternating load long term
Alternating load can cause the weakness such as pipes between devices weld seam to generate tired risk.
Various load (including periodical alternating load) can be effectively balanced this requires main equipment supports, while are had again
There is certain lateral degrees of freedom that can discharge thermal expansion and thermal walking, reduce thermal stress, optimize pipeline stress.Large-scale vertical such as main pump
Container needs to set multiple bearings, these equipment can generate center thermal walking and itself thermal expansion when changing due to cold and hot, if
Bearing is not parallel with connecting pipe axis will to occur multidirectional displacement, these bearings must possess multidirectional translation freedoms to discharge
Thermal stress.
Primary Ioops cooling agent main pump is to rotate machinery, with impacts such as mechanical rotation, fluid impact, cavitation erosions in operational process
With vibrations operating mode, branch is promised with damping, shock insulation function, prevents transmission, the amplification of vibrations.Therefore main pump branch under open ocean
Basic bearing requirements should be met by holding design, while also meet thermal stress release, ocean load-bearing and damping requirement.
