In sum, the maximum characteristics of the utility model nuclear safe level diesel generating set are antiseismic functions powerful on the structure, when earthquake takes place or (with) unit all can start and satisfied Essential Performance Requirements to it after the earthquake.
1. overall structure diesel engine and generator fuse by flywheel casing and connecting sleeve centering location, and the Flywheel disc of diesel engine is connected transferring power with the land of generator with bolt.
Because the flywheel casing of diesel engine and the connecting sleeve of generator have enough rigidity and intensity, the coaxial accuracy of its positioning boss and seam and axle is very high, can guarantee coaxality and integral rigidity that diesel engine is connected with generator.Torsional oscillation when reducing the unit running to greatest extent on the main shaft.
Diesel engine, generator and cooling water tank are directly installed on the public base, its mutual alignment accurate positioning, join strength height.
2. its structure of quake-proof seat is the steel structure box framework of a rigidity.
At diesel engine and generator leg installation position corresponding crossbeam reinforcement is arranged all, to guarantee the strength and stiffness of base.
3. the yielding rubber pad is arranged in quake-proof seat and the basis is installed between the base plate, the vibrations when effectively cutting off the unit running to the basis transmit and during the buffering earthquake seismic waves to the impact of unit.
Its function is as follows:
A. shock-absorbing function
The yielding rubber pad is made up of bowl type upper cover plate and funnel form base plate therebetween rubber material, is that a kind of pressure is cut compound shock insulation pad.
Because rubber material inside is suppressed during resonance the retardation of vibration, vibrate less, free vibration very fast decay, rubber pad has reduced the transmission that shakes.
B. antiseismic function
The yielding rubber mat structure is that a kind of pressure is cut compound rubber vibration isolation cushion, and this structure has advantages of high bearing capacity, lower rigidity and bigger damping ratio, and natural frequency can be accomplished 5Hz.
Because very low natural frequency, make beam when earthquake, be not easy to cause resonance, and impulse the very fast decay of bigger damping ratio when making earthquake.Simultaneously, the fine protection rubber material of the distinctive bowl of upper cover plate type design energy, funnel form base plate that rigidity is pure and ellipse plane structure strengthen the installation strength of base plate greatly.Bowl type upper cover plate and the funnel form base plate is concavo-convex interlocks, unit can not cause structural damage because of rubber pad damages yet when rubber pad is destroyed under the extreme case.
4. mounted component adopts special reinforcement measure on the quake-proof seat, the higher cooling water tank bi-side of center of gravity is installed installs tank bracket 10 additional, to form triangular support structure, increases the stability of water tank.
The empty filter that the mounting point is higher, its support adopt twin columns portal frame structure 4, have increased function of seismic resistance.
5. the control cabinet of the system intergration and switch cubicle adopt the integral frame-type structure, the node of Liang Yuzhu is all used the fastening reinforcement of three-support part, all side plates, top board, base plate flanging embed framework and fastening with screw, the door panel flap moulding also arranges that suitably buttress brace is strengthened, the electric components of these two face installations is cashier's office in a shop also used clamping plate, clip and band etc. give spacing, fix and tighten.
Cupboard side, two sides is stitched together has increased the rigidity of system, and underframe and base plate effectively are locked on the basis by pre-embedded bolt, is highly resistant to the impact of vibration.
Though a kind of rubber pad that is used for the damping of nuclear safe level diesel generating set of the utility model is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the utility model, also can make the variation and the modification of various equivalences under the situation that does not break away from the utility model spirit.Therefore, if in connotation scope of the present utility model to the variation of above-mentioned example, modification all will drop in the scope of claims of the present utility model.
