Abstract
The utility model relates to a vibration damper of an upper frame of a vertical-type water turbine generator. The vibration damper comprises an upper frame connecting plate, a vibration damper outer sleeve, a high-performance damping material, a vibration damper inner sleeve and a concrete foundation connecting plate, wherein the high-performance damping material is packed between the vibration damper outer sleeve and the vibration damper inner sleeve, and the upper frame connecting plate and the concrete foundation connecting plate are bonded with upper frame legs and a concrete foundation respectively to form integral structures. The principle of the vibration damper is as follow: the high-performance damping material is packed between the vibration damper outer sleeve and the vibration damper inner sleeve, so as to increase the level of damping coefficient of the whole vibration damper and achieve the vibration-suppressing effect; and the vibration damper has certain support stiffness which can reduce the vibration to certain degree.
Description
Technical field:
The utility model relates to a kind of vertical hydrogenerator upper spider damper.
Background technique:
High rotating speed vertical hydrogenerator upper spider causes commentaries on classics to raise frequently because rotating speed is too high under unit is overrun experiment, unit removal of load and runaway speed, be easy to the natural frequency of vibration conflict of upper spider, it is excessive to cause upper spider to vibrate under above several operating modes, destroy thereby can produce, influence unit safety operation some parts of unit.
Summary of the invention:
The purpose of this utility model provides a kind of have reliable vibration damping, vertical hydrogenerator upper spider damper simple in structure.The purpose of this utility model realizes by following structure: a kind of vertical hydrogenerator upper spider damper, by the upper spider connecting plate, the damper outer sleeve, high-performance damping material, the damper inner sleeve, the concrete foundation connecting plate is formed, upper spider connecting plate integral solder or bolt put together on the upper spider leg, damper outer sleeve integral solder is on the upper spider connecting plate, the concrete foundation connecting plate puts together on the concrete foundation with bolt, damper inner sleeve integral solder is on the concrete foundation connecting plate, and high-performance damping material is filled between damper outer sleeve and the damper inner sleeve.Filled high performance damping material between damper outer sleeve and the damper inner sleeve, upper spider connecting plate, concrete foundation connecting plate synthesize an integral body with its connection part handle respectively.The principle of the utility model structure is to have filled high-performance damping material between damper outer sleeve and the damper inner sleeve, make the damping constant of whole damper reach certain magnitude, but make it can reach the effect of shaking, damper itself also has certain support stiffness also can reduce vibration to a certain extent.
Description of drawings:
Fig. 1: vertical hydrogenerator upper spider damper assembling section
Embodiment:
As shown in Figure 1, a kind of vertical hydrogenerator upper spider damper, by upper spider connecting plate 1, damper outer sleeve 2, high-performance damping material 3, damper inner sleeve 4, concrete foundation connecting plate 5 is formed, upper spider connecting plate 1 integral solder or bolt put together on the upper spider leg, damper outer sleeve 2 integral solder are on upper spider connecting plate 1, concrete foundation connecting plate 5 usefulness bolts put together on the concrete foundation, and damper inner sleeve 4 integral solder are on concrete foundation connecting plate 5, and high-performance damping material 3 is filled between damper outer sleeve 2 and the damper inner sleeve 4.
Upper spider connecting plate 1, damper outer sleeve 2, damper inner sleeve 4, concrete foundation connecting plate 5 is decided according to the practical structures size, and high-performance damping material 3 is relatively decided according to inhibition of vibration of wanting to reach and actual vibration situation.
The principle of the utility model structure is to have filled high-performance damping material between damper outer sleeve and the damper inner sleeve, make the damping constant of whole damper reach certain magnitude, but make it can reach the effect of shaking, damper itself also has certain support stiffness also can reduce vibration to a certain extent.
