Working Principle
The electric dredger utilizes a robust electric motor to drive the centrifugal mud pump and hydraulic system. The cutter head, powered by an independent electric motor or hydraulic system, breaks up the sediment. The electric main pump then creates a vacuum to suck the slurry through the suction pipe. The entire process is managed by a centralized control panel, allowing operators to monitor and adjust power usage in real-time for optimal efficiency.
Applications
- Urban River Dredging: Cleaning silt from city rivers and canals without disturbing residents.
- Reservoir & Lake Maintenance: Restoring water storage capacity and water quality in drinking water reservoirs.
- Aquaculture Pond Cleaning: Efficiently removing nutrient-rich sediment from fish and shrimp ponds.
- Land Reclamation: Supporting eco-friendly land creation projects near environmentally protected areas.
