Abstract
The utility model relates to a kind of vertical hydrogenerator upper bracket vibration-proof structure, one circle pad of upper bracket centerbody welding is connected with bolt between cover plate, and cover plate welds with slide block, and slide block is connected with compressible spring, sleeve welds with jackscrew, and compressible spring and slide block are placed in sleeve.The utility model can significantly improve the radial rigidity of hydraulic generator upper bracket, and the natural frequency of unit improves, and avoids the scope increase that unit turns frequency, the vibration weakening of generator unit.Reduce the radial load effect of single jackscrew to basis, can not foundation failure be caused.
Description
Technical field:
The utility model relates to a kind of vertical hydrogenerator upper bracket vibration-proof structure.
Background technology:
High rotating speed suspended hydrogenerator group rotating speed is high, vibration is large, cause generator operation unstable, in order to reduce Generator Vibration, vibration-proof structure installed by generator upper bracket, and the radial rigidity of upper bracket increases, and the natural frequency of unit improves, avoid the scope increase that unit turns frequency, the vibration weakening of generator unit.Existing high rotating speed suspended hydrogenerator upper bracket structure adopts jack structure to be connected with basis, damping vibration DeGrain, and produces larger radial load to basis.
Summary of the invention:
The purpose of this utility model is to provide a kind of radial rigidity significantly improving hydraulic generator upper bracket, improves the natural frequency of unit, weakens a kind of vertical hydrogenerator upper bracket vibration-proof structure of generator unit vibration.The technical solution of the utility model is:
One circle pad (1) of upper bracket centerbody welding is connected with bolt between cover plate (2), cover plate (2) welds with slide block (3), slide block (3) is connected with compressible spring (4), sleeve (5) welds with jackscrew (6), and compressible spring (4) and slide block (3) are placed in sleeve (5).
Technique effect:
In the utility model structure, one circle pad (1) of upper bracket centerbody welding is connected with bolt between cover plate (2), compressible spring (4) is connected with slide block (3) and is placed in sleeve (5), the radial rigidity of hydraulic generator upper bracket can be significantly improved, the natural frequency of unit improves, avoid the scope increase that unit turns frequency, the vibration weakening of generator unit.Multiple jackscrew (6) is connected with basis, reduces the radial load effect of single jackscrew to basis, can not cause destroying basis.
Operation principle:
In rotating machinery running, by the effect of exciting power, machinery can produce vibration, once the natural frequency of machinery is consistent with the frequency of outside exciting force, covibration will occur, thus causes the excessive deformation of machinery.The scope that mechanical natural frequency avoids outside excitation force frequency is larger, and so the vibration of machinery is less.One circle pad (1) of upper bracket centerbody welding is connected with bolt between cover plate (2), compressible spring (4) is connected with slide block (3) and is placed in sleeve (5), the radial rigidity of hydraulic generator upper bracket can be significantly improved, the natural frequency of unit improves, avoid the scope increase that unit turns frequency, the vibration weakening of generator unit.Multiple jackscrew (6) is connected with basis, reduces the radial load effect of single jackscrew to basis, can not cause foundation failure.
Existing high rotating speed suspended hydrogenerator upper bracket structure adopts jack structure to be connected with basis, damping vibration DeGrain, and produces larger radial load to basis.Long vibration, can produce the parts of unit and destroy.
Accompanying drawing illustrates:
Fig. 1 is vertical hydrogenerator upper bracket vibration-proof structure figure.
Embodiment:
As shown in Figure 1, a kind of vertical hydrogenerator upper bracket vibration-proof structure, a circle pad 1 of upper bracket centerbody welding is connected with bolt between cover plate 2, cover plate 2 welds with slide block 3, slide block 3 is connected with compressible spring 4, and sleeve 5 welds with jackscrew 6, and compressible spring 4 and slide block 3 are placed in sleeve 5.
