Technical Principles

The core working principle of our large dredgers is based on high-efficiency hydraulic conveying and intelligent working condition regulation. The complete implementation logic (input-processing-output-result) is as follows:
1. The cutter or impeller breaks underwater sediments to form slurry.
2. The high-lift pump transports the slurry through pipelines to the designated discharge area.
3. The intelligent control system monitors working conditions in real time and adjusts operating parameters automatically to ensure stable performance.
