Embodiment 1

[0027] Click the power button on the interface of the terminal equipment, select "Mobile Chassis" in the preprocessing mode after starting up, and press the front, back, left and right keys according to the actual situation to make the device quickly move to the vicinity of the tested tube sample, also in the preprocessing mode Select "height adjustment arm", according to the actual situation, press the front, back, left, right, up and down keys to make the manipulator quickly move to the surface of the tube sample, and finally press the front, back, left, right, up and down keys according to the actual situation. The manipulator is precisely positioned to the detection starting point, which is generally set at the neutral plane of the pipeline where the detection starts, and the detection preprocessing is completed.

[0028] Enter the diameter of the pipeline to be detected, enter 540 on the device terminal interface, and click the "OK" button. In the detection direction mode...

Embodiment 2

[0032] The detection preprocessing work is the same as that in Embodiment 1, input the diameter of the pipeline to be detected, input 540 on the device terminal interface, and click the "OK" button. Select "Landscape" detection in the detection orientation mode. In the detection program mode, select the detection program to be used. In this embodiment, start from cleaning the tube sample, that is, select "cleaning agent". Select "Continuous" in the operation mode, so far, all the setting work has been completed, click the "Start" button to start the detection. The manipulator will start from the starting point and perform pre-cleaning in sequence along the medium flow direction, wait for the tube sample to dry (according to the ambient temperature range, the system is set to 3 minutes), apply penetrant, clean, and wait for the tube sample to dry (according to the ambient temperature range, the system Set it to 3 minutes), apply the imaging agent, and do not need human manipul...

Abstract

The invention discloses a method for automatic coloring penetration detection in a pre-detection stage of a power station pipeline. A detection instrument is adopted for detection; the detection instrument comprises a mechanical arm, a movable chassis and a height adjusting arm, the height adjusting arm is arranged on the movable chassis, the mechanical arm is installed at the end of the height adjusting arm, and the detection instrument is provided with cleaning rag and terminal equipment. The detection agent comprises a cleaning agent, a penetrating agent and a developing agent; the detection method sequentially comprises the following steps: performing pre-cleaning, performing drying, applying a penetrant, removing excess penetrant, performing drying and applying a developer. The environmental conditions are as follows: in the whole detection process, the temperature of the penetration detection agent, the surface temperature of the workpiece and the operating temperature are withinthe temperature range of 10-50 DEG C. According to the invention, the surface of a detected part can be accurately identified, and manual actual addition of a cleaning agent, a penetrating agent anda developing agent is replaced, so that the harm of the penetrating agent and the developing agent to a human body is avoided, the field detection efficiency is improved, the detection period is shortened, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a power station pipeline penetration detection technology, in particular to a method for automatic coloring penetration detection in the power station pipeline pre-inspection stage. Background technique [0002] Pre-installation inspection (hereinafter referred to as pre-inspection) refers to random inspection of equipment quality at the stage of equipment pre-inspection according to the standards and specifications of electric power and related industries. As the last hurdle to supervise the quality of equipment before the power plant is put into operation, the pre-inspection advantageously fills the loopholes in the manufacturing of equipment in the manufacturing plant, complements each other with equipment manufacturing supervision, and is of great significance to ensure the safe operation of the unit after it is put into operation. Penetration testing technology is a non-destructive testing method for checking opening defec...
