The specific technical indicators are as follows:
⑴ Operating environment temperature: -40 ℃~70 ℃;
⑵ Operating environment humidity:<90%;
⑶ Crawling distance: 4km (the round-trip distance during exposure operation is limited by the pipe diameter and wall thickness);
⑷ Scope of pipe diameter detection: Φ 159~ Φ 168 (mm);
⑸Crawling speed: 12~14m/min；
⑹ Maximum transparency thickness: 12mm (cone target);
⑺ Radiation source: X-ray machine (120kV, 3mA);
⑻ The exposure time is continuously adjustable, accurate to 1 second;
⑼ Positioning error: ± 5mm (after correcting for forward and backward errors);
⑽ Power supply: lithium battery 110v/10Ah;
⑾ Climbing ability: 27 degrees under optimal conditions;
⑿ Weight: Vehicle body 23kg, X-ray generator 10kg;
⒀ External dimensions: X-ray generator φ 120 mm x 515mm
Spider φ 127mm x 1200mm;
⒁ Turning radius: ≥ 10D;
⒂ Built in Siemens programmable controller for precise control of equipment;
⒃ Single wheel drive, the crawler can run smoothly in the pipeline, and the universal connection (between the ray generator and the vehicle body) facilitates the crawler to turn inside the pipeline;
⒄ Has constant current and constant voltage output, with uniform film density;
⒅ Equipped with detection for water, obstruction (overcurrent), overvoltage, undervoltage, and thermal protection of the pipe head. When any of the above conditions are met, the crawler will reverse and display the cause of the malfunction.
