An ultrasonic automatic inspection device for large cylinder and head forgings

Abstract

The invention belongs to the technical field of non-destructive testing of large-scale forgings of nuclear reactor pressure vessels, evaporators, and voltage stabilizers of nuclear power plants, and in particular relates to an ultrasonic automatic inspection device for large-scale cylinder and head forgings. The device includes door guide rail, horizontal telescopic rod, vertical telescopic rod, turntable, test block storage rack, gong-shaped forging, swing linear module, installation base; door guide rail is installed on the installation base, and the installation base There is a sinking circular groove in the middle, and the turntable is placed in it. The horizontal telescopic rod is installed in the vertical direction of the door guide rail and can slide along it. The vertical telescopic rod is installed in the horizontal direction of the door guide rail and can slide along it. The swing linear mold The groups are respectively installed on the head of the horizontal telescopic rod and the vertical telescopic rod, the gong-shaped forging of the measured object is installed on the turntable, and the test block storage rack is installed on the front end within the travel range of the door guide rail. The invention guarantees the consistency of parts in the processing stage and subsequent operation and service inspection data, and guarantees product quality.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing of large-scale forgings of nuclear reactor pressure vessels, evaporators, and voltage stabilizers of nuclear power plants, and in particular relates to an ultrasonic automatic inspection device for large-scale cylinder and head forgings. Background technique [0002] The primary circuit system of a nuclear power plant contains the high-temperature and high-pressure cooling medium (water) during reactor operation. If the primary circuit system equipment leaks, it will cause unplanned temporary shutdown and cause large economic losses. At the same time, it may cause serious nuclear leakage accidents. Therefore The quality requirements of primary circuit equipment and pipelines are very high. In order to ensure the safety requirements of equipment, a series of relevant inspection specifications have been formulated, and inspection requirements for key equipment have been put forward at...

AI Technical Summary

Problems solved by technology

[0005] Large-scale tubular forgings of nuclear power plants are currently in the factory production stage and are inspected manually. Due to the rapid development of domestic nuclear power plants, large-scale forgings have increased sharply. According to nuclear power-related inspection specifications, these parts need to be inspected during the production and processing stage, and the amount of manual inspection is heavy.

Due to the limitations of manual inspection, there is no data retention, and there are human factors affecting the inspection quality
