Anti-seismic detection test bed for nuclear-grade pump valve

Abstract

The invention discloses a nuclear-grade pump valve anti-seismic detection test bed which comprises a base, moving wheels, a stand column, pipeline fixing bolts, a pipeline, an additional mass block, an electromagnetic chuck, a chuck mounting sleeve and chuck fixing bolts. The middle of the base is in a disc shape, and four strip-shaped structures extend out of the edge of the disc and are distributed at equal intervals of 90 degrees. And moving wheels are arranged at the bottom of the strip-shaped structure. The base is provided with a pipeline fixing bolt connected with the pipeline, and the stand column is welded to the base. The stand column is used for arranging a suction cup installation sleeve, a suction cup fixing bolt and an electromagnetic suction cup. And the additional mass block is made of a material with high electromagnetic adsorbability and high density, and is arranged on the surface of one side, facing the upright post, of the pipeline. The device has the beneficial effects that the anti-seismic detection test of nuclear power equipment can be flexibly, conveniently and reliably carried out, and the device has a plurality of innovations and advantages that the device is low in total cost, reliable and flexible in structure, convenient to adjust the initial total energy of falling of the pipeline, simple to operate and low in maintenance difficulty.

Description

technical field [0001] The invention belongs to the field of anti-seismic tests, and in particular relates to a test bed for anti-seismic detection of nuclear pump valves. Background technique [0002] For equipment with high safety requirements, the anti-seismic performance cannot be ignored. All industries attach great importance to anti-seismic detection, especially for nuclear power. However, at present, there is a lack of dedicated anti-seismic test benches in the nuclear power industry, and they are still mainly built and assembled temporarily. The test benches have disadvantages such as poor mobility, high cost, unstable structure, low precision, and difficult operation. Therefore, it is necessary to develop a more suitable test bench, which is convenient for carrying out the test of the upright equipment in the workshop after the earthquake and the impact on the nuclear power equipment on the ground. , High ranging accuracy, low operation difficulty, low maintenance...
