Abstract

The invention discloses a test device for impact wear of heat exchange tubes, which belongs to the technical field of heat exchange tubes and solves the problem that the heat exchange tubes of nuclear power steam generators cannot be further explored due to contact wear. The heat exchange tube impact wear test device includes a base, a reciprocating device and a heat exchange tube impact device. The reciprocating device includes a cylinder and a piston rod provided on one side of the cylinder. A heat exchange tube is set on the free end, and the piston rod is used to drive the free end to reciprocate, so that the two heat exchange tubes are constantly impacted, and a displacement sensor is installed on the side of the piston rod, between the piston rod and the free end Set up a tension and pressure sensor to measure and transmit the displacement of the piston rod and the impact force between the heat exchange tubes, and finally analyze it to complete the impact wear test of the heat exchange tubes.

Description

technical field [0001] The invention relates to the technical field of heat exchange tubes, in particular to a heat exchange tube impact wear test device. 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 nuclear power plants, flow-induced vibrations cause U-shaped tubes to vibrate in-plane in the bend area, resulting in various frictional couplings of heat exchange tubes during operation, including impact wear, fretting wear, and sliding wear. In recent years, cases of contact damage to heat exchange tubes have been gradually discovered, and there are few studies on such failures. For this reason, we designed such a device to study the failure mechanism of heat exchange tubes. It is of great significance to ensure the safe operation of nuclear power plants. Contents of the invention [0003] The present inventi...
