Introduction
In many complex and limited construction scenarios, large dredging vessels cannot enter the site for operation, and traditional electric submersible pumps have obvious functional defects. Ordinary submersible pumps only have single suction function, and cannot break compacted hard silt, aged clay and layered sediment. When encountering hard bottom mud and mixed sediment, they are prone to suction blockage, low slurry concentration and ineffective pumping. At the same time, underwater electric equipment has potential electric leakage risks, which brings great safety hazards to underwater construction.
Ocean Pump hydraulic submersible slurry pump with cutter is specially developed for narrow-space, dead-angle and complex underwater dredging conditions. It integrates underwater hydraulic cutting, stirring and high-concentration slurry suction functions. Driven by full hydraulic power, it has no electrical safety risks. The front-end high-hardness alloy cutter head can efficiently crush hard sediment, and the built-in stirring structure prevents sediment deposition. The whole machine can dive deeply underwater for omnidirectional dredging, becoming the irreplaceable core equipment for foundation pit cleaning, pond desilting, trench dredging and dead-angle sediment removal.
Working Principle & Core Design
1. Full Hydraulic Power Driving System
The pump body is completely driven by an independent hydraulic station, abandoning the traditional underwater motor driving mode. The hydraulic power outputs stable and high torque, which can ensure that the cutter head maintains strong crushing force when encountering hard clay and compacted sediment. The fully hydraulic structure completely eliminates hidden dangers such as underwater electric leakage and motor burnout. It features safe operation, stable power output and strong environmental adaptability, suitable for long-term continuous underwater diving work.
2. Front-End Alloy Cutter & Stirring Integrated Structure
The front end is equipped with high-hardness integral alloy cutter head and auxiliary rotary stirring blades. The cutter head can peel and crush aged hard silt, compacted clay and loose gravel sediment layer by layer. The stirring blades continuously stir the surrounding sediment to avoid suction inlet blockage and sediment deposition. The integrated cutting and stirring design greatly improves the mixing uniformity of water and sediment, effectively increasing the solid content of conveyed slurry and significantly improving dredging efficiency.
3. Full Underwater Self-Priming No-Dead-Angle Operation
The whole machine adopts fully submersible integrated design, without manual water filling and self-priming procedures. It can work at any underwater depth, freely adjust the working angle, and realize omnidirectional dead-angle-free dredging. It is not affected by water level fluctuation, terrain obstacles and narrow space limitations, and can complete precise dredging in complex environments where large equipment cannot reach.
4. High-Chrome Wear-Resistant Flow Channel Configuration
The core flow-through parts such as impeller and pump body flow channel are made of high-chrome wear-resistant alloy materials. After special processing technology, they have excellent anti-scouring and anti-abrasion performance, which can adapt to long-term impact and scouring of sediment containing fine sand, gravel and impurity particles. The service life of vulnerable parts is far longer than that of ordinary submersible pumps, reducing long-term maintenance costs.
