Product Overview
The PQWT PQ325C and PQ325C+ are pipeline inspection robots designed for pipes with an inner diameter of 350 mm or larger. They are suitable for visual inspection in drainage systems and other pipelines where access is limited or manual inspection is difficult.
The system combines a mobile inspection robot, dual cameras, an adjustable lighting system and a touch-screen controller. It provides real-time images of the pipe interior, helping operators identify potential structural defects, sediment buildup, foreign objects and other conditions.
The front camera supports horizontal and vertical movement, while the rear camera provides a fixed rear view. This dual-camera configuration allows operators to observe different areas of the pipeline during inspection.
Two wheel sizes are available to accommodate different pipe conditions and inspection requirements. The robot is designed for use in environments where stable movement and reliable visual access are important.
Key Features
1. High-Definition 2K Imaging
The PQWT PQ325C uses a 4-megapixel camera system with 2K image resolution to provide detailed views of the pipeline interior.
2. Dual-Camera Inspection
The front and rear cameras provide different viewing angles, helping operators observe the pipeline and reduce blind spots during inspection.
3. Flexible Front Camera
The front camera supports 270° horizontal rotation and 180° vertical rotation, allowing operators to adjust the viewing direction during inspection.
4. Two Wheel Sizes
The system supports 125 mm and 180 mm wheels. Operators can select the appropriate wheel configuration according to the pipe diameter and inspection conditions.
5. Inspection in Challenging Environments
The robot is designed for use in pipeline environments that may contain sediment, accumulated water and uneven surfaces. Actual operating performance depends on the site conditions and equipment configuration.
6. Touch-Screen Control
The 11.5-inch touch-screen tablet supports inspection-related functions, including project information, tilt display, direction display, photography and video recording.
Product Applications
Drainage and Sewer Inspection
The PQWT PQ325C can support visual inspection of drainage and sewer systems, helping operators investigate internal pipe conditions and identify areas requiring further assessment.
Potential applications include:
- Routine drainage system inspection
- Inspection after pipeline renovation or dredging
- Investigation of sediment buildup and restricted flow
- Inspection of pipe corrosion and breakage
- Identification of joint misalignment
- Inspection of foreign objects and blockages
- Assessment of internal structural conditions
Inspection of Difficult-to-Access Areas
Pipeline inspection robots can help operators obtain visual information in locations where direct manual access is difficult.
Depending on the operating environment and equipment configuration, the PQ325C series can be considered for inspection of drainage pipelines, ventilation ducts, trenches and other enclosed spaces.
New Drainage System Acceptance Inspection
The system may be used to support visual checks during the acceptance of newly constructed or renovated drainage systems. Inspection requirements should be determined according to the applicable project standards and customer specifications.
