Introduction

In large-scale dredging projects including deep reservoir sediment removal, main river flood control regulation, large-area land reclamation and industrial tailings disposal, short-distance slurry discharge can no longer meet actual construction demands. Traditional standard dredgers suffer from obvious drawbacks such as limited conveying distance, frequent floating pipeline relocation, dependence on auxiliary barge equipment, intermittent construction and low overall efficiency, which greatly extend project cycles and increase comprehensive construction investment.
The Ocean Pump long distance discharge cutter suction dredger is specially upgraded with high-head heavy-duty dredge pump units and optimized overall pipeline hydraulic simulation design. It realizes stable, high-concentration ultra-long-distance slurry transportation without supporting booster pump stations, effectively improving construction continuity and stability while greatly reducing auxiliary equipment input and project operating costs. It has become the most reliable preferred equipment for medium and large-scale long-distance pipeline dredging projects worldwide.

Professional Long-Distance Dredging System Design

1. High-Head High-Chrome Dredge Pump Core

Equipped with Ocean Pump independently customized high-head heavy-duty dredge pumps, the core flow-through parts are made of high-hardness high-chrome alloy materials. This professional configuration provides powerful stable pressure output and excellent anti-wear performance. Even under extreme working conditions of long-distance conveying, high pipeline resistance and high-speed slurry scouring, the pump maintains stable slurry concentration and continuous uninterrupted output, effectively avoiding common problems such as insufficient conveying pressure, pipeline blockage and rapid wear of vulnerable parts.

2. Optimized Whole-Machine Hydraulic Matching

Through professional CFD hydraulic simulation and overall machine debugging, we realize precise matching of total engine power, slurry suction flow rate and pipeline resistance parameters. After repeated industrial testing and optimization, the dredger can achieve stable direct discharge of 800m–1500m ultra-long distance without additional booster stations and intermediate transfer equipment, greatly simplifying the overall construction system and improving on-site construction efficiency.

3. Wear-Resistant Pipeline Supporting System

Supporting complete sets of high-pressure anti-wear floating pipelines and fixed shore pipelines, all pipeline inner walls adopt special anti-abrasion lining technology. The whole conveying system is professionally adapted to long-term high-speed scouring of sand-gravel mixed slurry, featuring low hydraulic loss, stable conveying performance and ultra-long service life, which effectively reduces daily pipeline maintenance and replacement costs for long-distance dredging projects.

Unique Advantages
