Abstract

The invention discloses a clamping device and a fixing mechanism of a heat exchange tube, comprising: a first clamping assembly, used to clamp one end of the heat exchange tube; a second clamping assembly, used to fix the other end of the heat exchange tube ; the fixed frame; the first fixed seat and the second fixed seat, the first fixed seat and the second fixed seat respectively fix a first clamping assembly; the sliding seat, which is arranged on the fixed frame; the balance assembly, Used to connect two heat exchange tubes. In the present invention, in the clamping device, a rotating pair is formed between the slide rail and the first sliding block, which unloads the pre-tightening force generated when the heat exchange tube is tightened, so that the test experiment can be carried out smoothly; in the fixing mechanism, at the same time The two heat exchange tubes are fixedly clamped, and a balance assembly is set between the two heat exchange tubes, which avoids the interference of the force generated by the heat exchange tubes when they are pre-tightened on the experiment, and greatly reduces the error of the experiment.

Description

technical field [0001] The invention relates to the technical field of heat exchange tubes in nuclear power steam generators, in particular to a clamping device and a fixing mechanism for heat exchange tubes. Background technique [0002] Heat exchange tubes are an indispensable part of nuclear power steam generators, which perform heat exchange functions at specified temperatures, pressures, and different media. In the nuclear power plant, due to the flow-induced vibration, the U-shaped tube vibrates in the bend area, resulting in various frictional couplings between the heat exchange tube and the support plate during operation, including impact wear, fretting wear, sliding wear, etc. . In recent years, cases of contact damage to heat exchange tubes have been gradually discovered, so it is necessary to conduct friction test experiments on heat exchange tubes. [0003] However, during the friction test of the heat exchange tube, the heat exchange tube will be twisted and b...
