Dredge Pump
Dredge pumps are widely used in metallurgical chemicals, pulp and paper, power generation, mining and mineral resources, construction building industry, etc.
Capacity:1800-25000t/h
Applicable materials: This pump is suitable for river dredging, reservoir dredging, coastal reclamation, deep-sea mining, tailings selection, metal smelting slag transportation, etc.
Description
Dredging pump, also called mud pump. It is usually used for large-scale dredging and construction areas, which are mainly used for rivers, lakes, dredging, and wind-blowing engineering in disrepair. The dredging system is composed of a pump head, reduction gearbox, high elastic joint, and ship transmission monitoring system, which has good ship performance, good dredging performance, high efficiency, reliable shaft seal, comprehensive economic benefits, and fully meets the requirements of dredgers for mud pumps.
Advantages
- The pump has a simple and reliable structure, which is easy to disassemble and maintain. It is made of high chromium wear-resistant alloy material and has a long service life.
- This series of dredging pumps is a single-stage single suction horizontal centrifugal pump, with a wide impeller channel and strong passing ability. It is not easy to block when pumping sand, gravel, or high plastic clay and has a super strong excavation suction capacity.
Principle
The dredge pump is the equipment of a hydraulic dredging boat, which mainly utilizes the movement of water to achieve the dredging purpose. It loosens the underwater soil layer through mechanical or high-pressure water cutting, mixes sediment with water, and forms a certain concentration of mud water mixture. Then, the mud is vacuum sucked into the mud pump through the suction port on the boat. The purpose of dredging and filling is achieved by discharging it to the hopper of the dredger, directly to the mud barge side, or transporting it to the reclamation area through the discharge pipeline.
