PQ325E is an automatic pipeline inspection robot specially designed for municipal pipeline network inspection. It is suitable for pipes with a diameter of ≥DN250, meets a variety of pipeline inspection needs, and supports an operating distance of up to 100 m, making it an efficient and intelligent device for pipeline inspection.
The device is equipped with a dual-motor six-wheel drive system, with an obstacle-crossing height of ≤100 mm and an obstacle-crossing angle of ≤30°. It comes with three sets of anti-slip quick-release wheels in 4-inch, 6-inch, and 10-inch sizes, allowing quick replacement to suit different pipeline environments. The body uses stainless steel anti-collision beams and handles, with an IP68 protection rating, making it waterproof, durable, and suitable for complex operating environments inside pipelines.
It features a powerful visual configuration with front and rear 5-megapixel cameras. The camera system supports 360° horizontal rotation, 180° radial adjustment, and 80° lifting, together with twelve 3 W fill lights, providing clear, blind-free images. It also supports one-key self-reset for convenient operation. The system is equipped with a 100 m cable reel with a tensile strength of 200 kg, supporting automatic, manual, and manual-assisted cable winding. Electronic encoder distance measurement provides accurate metering. With wireless tablet control, users can operate the device by connecting to the dedicated WiFi. It supports real-time video recording, screenshots, engineering information overlay, and complete data storage.
The cable reel is equipped with a 60 V 15 Ah battery and provides approximately 7 hours of battery life. The equipment is easy to operate and runs stably. It is widely used for municipal pipeline network inspection, including rainwater and sewage pipelines.
Application Scenarios
Used for routine maintenance and inspection to investigate structural defects, weld defects, structural conditions, foreign-object blockages, damage, and other pipeline conditions. It replaces manual inspection for high-risk and difficult tasks, ensuring that the inside of the pipeline is clear and safe.
Sewage leakage detection for environmental protection.
Completion acceptance inspection of newly built drainage systems.
Completion acceptance inspection after drainage system renovation or dredging.
Inspection of excessive unknown infiltration water or insufficient water-carrying capacity entering sewage treatment plants through drainage systems.
Investigation of causes such as pipeline siltation and poor drainage.
Inspection of mixed flow between directly dischargeable sewage and sewage requiring treatment.
Inspection of operating conditions such as corrosion, damage, joint misalignment, siltation, scaling, and collapse.
Locating hidden points where inspection openings cannot be located or pipeline directions are unclear due to drainage system or infrastructure construction impacts.
Inspection of ventilation ducts, trenches, narrow enclosed building spaces, and similar environments.
