PQ325A and PQ325A+ are high-definition pipeline inspection robots designed for small-diameter pipes. With a compact structure, the robot body is small and lightweight. It can enter pipes with a minimum diameter of ≥110 mm for inspection work, featuring outstanding miniaturization advantages over competing products.
Equipped with a 2-megapixel HD camera system, it provides clear and stable images. It also includes six high-brightness LED lights and a detachable flashlight, with a visible range of up to 2 m. The system integrates traveling, real-time inspection, photo capture, video recording, custom watermarks, and other practical functions. It ensures inspection performance while significantly reducing operating costs, making it an ideal choice for users seeking high cost performance.
The main body is made of aluminum alloy and stainless steel, providing a strong and durable structure with excellent waterproof and corrosion-resistant performance. It can handle complex pipeline environments such as humidity and accumulated water. It supports a cable length of up to 100 m and is suitable for daily inspection and maintenance of various pipelines.
Application Scenarios
Used for daily maintenance and inspection to identify structural defects, weld defects, structural conditions, foreign-object blockages, damage, and other issues in various pipelines. It can replace manual work in high-risk and difficult inspection tasks, helping ensure pipelines remain clear and safe.
◆ Sewage leakage detection for environmental protection;
◆ Completion acceptance of newly built drainage systems;
◆ Completion acceptance after drainage system renovation or dredging;
◆ Inspection of excessive unidentified infiltration water or insufficient water receiving capacity in sewage treatment plants through drainage systems;
◆ Investigation of causes such as pipeline siltation and poor drainage;
◆ Inspection of confluence between directly dischargeable sewage and sewage requiring treatment;
◆ Inspection of operating conditions such as pipeline corrosion, damage, joint misalignment, siltation, scaling, and collapse;
◆ Locating hidden points where inspection openings cannot be identified or pipe section directions are unclear due to drainage system or infrastructure construction impacts;
◆ Inspection of ventilation ducts, trenches, narrow enclosed building spaces, and similar environments.
