Overview
DN jet-suction type dredger, by means of the water power, conveys the silt (or fine sand, sea sand, etc.) lifted by the water column from the high pressure gun to the destination through pipelines by the action of water pump. The dredger is novel in design, simple and convenient in operation and high in efficiency. It is suitable for dredging channel, desilting lake and reservoir, exploiting seashore, clearing port and pier, pumping sand and so on. The dredger has played an important role in cleaning silt and strengthening dyke for Yellow River.
Structure
The dredger consists of a ship body, a conveying system, a water inlet system, an empty system and so on, wherein the conveying system comprises power, a clutch, a mortar pump, etc, and the empty system comprises a high-pressure hydraulic pump, a vacuum extractor and so on.
