Embodiment Construction

[0056] The fixing mechanism includes: a fixing frame 100; a first fixing seat 210 and a second fixing seat 220, the first fixing seat

[0057] The preloading force loading mechanism includes two preloading force loading units 500, and each preloading force loading unit 500 is used for

[0059] In the case where the balance assembly 400 is not provided, when the heat exchange tube 700 is preloaded, the lateral direction of the heat exchange tube 700 will be caused.

[0061] Further, the relative position between the sliding seat 360 and the fixing frame 100 can be adjusted, so that the first clamping assembly

[0062] The relative positions between the two second clamping assemblies 300 and the sliding seat 360 can be adjusted;

[0065] The first clamping assembly 200 clamps either end of the heat exchange tube 700, and the second clamping assembly 300 clamps the heat exchange tube 700.

[0066] Before the heat exchange tube 700 is tested, the heat exchange tube 700 needs to be fixe...

Abstract

The invention discloses a test device for heat exchange tubes, comprising: a fixing mechanism, the fixing mechanism includes: a fixing frame, a first fixing seat and a second fixing seat, a first clamping component and a second clamping component; a balance component, It is used to connect two heat exchange tubes; the preload loading mechanism includes two preload loading units, each preload loading unit acts on a heat exchange tube respectively, and the two preload loading units are respectively arranged on the opposite side of the balance assembly. In the present invention, 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; at the same time, the two heating tubes are fixedly clamped, and the The balance component is set between the heat exchange tubes, which avoids the interference of the force generated by the heat exchange tubes during the preloading of the test, and greatly reduces the error of the experiment.

Description

A test device for heat exchange tubes technical field The present invention relates to the technical field of heat exchange tube in nuclear power steam generator, relate in particular to a kind of test device of heat exchange tube set. Background technique [0002] The heat exchange tube is an indispensable part of the nuclear power steam generator. Heat transfer in the medium. In the nuclear power plant, the U-shaped tube vibrates in the bend area due to the flow-induced vibration, resulting in the heat exchange tube Coupling with the support bearing plate in various forms of friction during operation, including impact wear, fretting wear, sliding wear Wait. In recent years, the cases of contact damage of heat exchange tubes have been gradually discovered, so it is necessary to carry out friction tests on heat exchange tubes. test. However, in the process of carrying out the friction test experiment to the heat exchange tube, because the fixing mechanism and the...
