Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 , figure 2 As shown, a gasket for improving the resonance of vertical equipment according to the present invention includes a small gasket A1, a small gasket B2, a small gasket C3, and a large gasket 4.

[0022] The new spacer is in the shape of a ring as a whole, matching with the ring base of the vertical equipment, and the center of the ring is 0 point. The new gasket consists of two materials. The small gasket A1, the small gasket B2, and the small gasket C3 are made of the same material, and the large gasket 4 is made of another material. The large spacer 4 has a circular ring shape as a whole, and several circular bolt holes are arranged on it, so that the connecting bolts of the equipment and the foundation pass through. The small gasket A1, the small gasket B2, and the small gasket C3 are respectively arra...

Abstract

The invention relates to a gasket for improving resonance of vertical equipment. The gasket can improve resonance on the premise of not changing an original installing structure so as to reduce equipment vibration. The gasket comprises a small gasket A, a small gasket B, a small gasket C and a large gasket, wherein the large gasket is annular and is provided with a plurality of circular bolt holes, the small gasket A, the small gasket B and the small gasket C are correspondingly arranged below the large gasket, the small gasket A, the small gasket B and the small gasket C are correspondingly apoint A, a point B, a point C, the point A, and the point B and the point C are positioned on a circle formed by circle centers of the bolt holes and cannot be positioned in bolt hole areas. According to the gasket, the resonance can be improved on the premise that the original installing structure is not changed, so that the equipment vibration is reduced.

Description

technical field [0001] The invention relates to a gasket for improving the resonance of vertical equipment, which can improve the resonance and reduce the vibration of the equipment without changing the original installation structure. Background technique [0002] Most of the rotating equipment in nuclear power plants is of vertical structure. This type of vertical structure is often due to insufficient design considerations, and resonance occurs during on-site installation. Since the speed of many equipment cannot be changed, in order to control the resonance, it is necessary to redesign the selection and carry out on-site transformation, and change the natural frequency of the equipment to reduce the resonance response. Such work takes a very long time and will restrict the construction and operation of the power plant. [0003] Vertical equipment generally connects the ring base at the bottom to the foundation through bolts, and gaskets are sometimes arranged between t...
