12-Inch Straight-Arm Jet Suction Dredger
12-Inch Straught-Arm Jet Suction Dredger As a key professional floating sand extraction and dredging equipment for waterway dredging, sand mining, reservoir desilting, and port maintenance, the12-Inch Straight-Arm Jet Suction Dredger is widely used in rivers, lakes, reservoirs, ports, coastal shallow areas, and artificial lakes that require efficient sand suction, dredging, and sediment cleaning operations. Facing harsh and complex working conditions such as variable water levels, shallow water, uneven sediment distribution, and mixed sand and gravel, traditional sand extraction equipment and single-function dredgers commonly suffer from low efficiency, poor sand suction capacity, high blockage rate, limited operation scope, and inability to adapt to dynamic water level changes. Our independently designed and manufactured 12-Inch Straight-Arm Jet Suction Dredger adopts an integrated structure of straight-arm adjustment, jet breaking, sand suction, conveying, and floating positioning, equipped with a high-efficiency 12-inch-specific jet suction sand pump system, adjustable straight-arm device, stable floating hull, and reliable power system. It integrates high sand suction efficiency, strong sediment breaking capacity, flexible straight-arm adjustment, wide adaptability, stable operation, environmental protection, and energy saving, and is specially designed for sand extraction, dredging, sediment cleaning, and channel improvement in various water areas, especially suitable for occasions where fixed sand extraction equipment is difficult to construct, water levels fluctuate greatly, and sediment depth varies. From shallow urban landscape lakes, large natural rivers to coastal shallow zones and reservoir areas, this 12-inch straight-arm jet suction dredger can operate safely and efficiently with flexible straight-arm adjustment, making it an indispensable core equipment for water conservancy dredging, sand mining projects, reservoir maintenance, and port improvement systems.
Core Structure & Working Principle(12-Inch Straight-Arm Jet Suction Dredger)
The 12-inch straight-arm jet suction dredger adopts an integrated operation structure composed of a 12-inch dedicated jet suction sand pump system, high-pressure jet device, adjustable straight-arm device, conveying pipeline system, floating hull, power system, and positioning system, realizing one-stop completion of straight-arm adjustment, jet breaking, sand suction, conveying, floating positioning, and continuous operation, with specifications perfectly matched to the 12-inch design and straight-arm jet suction dredging functional requirements[1]. As a floating sand extraction and dredging equipment with a unique straight-arm structure, the 12-inch straight-Arm jet suction dredger can flexibly adjust the height and depth of the suction pipe through the straight-arm device, adapt to dynamic water level changes and uneven sediment distribution, eliminate the need for complex underwater construction, and ensure efficient sand suction in different water depths and sediment thicknesses.
1. Jet Suction Sand Pump & Straight-Arm Device: 12-Inch Dedicated, Flexible & Wear-Resistant(12-Inch Straight-Arm Jet Suction Dredger)
The core sand extraction device is equipped with a 12-inch high-efficiency jet suction sand pump and a matching adjustable straight-arm device, both customized for the 12-inch straight-Arm jet suction dredger’s overall size and floating working characteristics, matched with a high-pressure jet pump to form a complete straight-Arm jet suction system[1]. The adjustable straight-arm device can flexibly lift and lower the suction pipe, adjust the suction depth according to sediment thickness and water level changes, and ensure that the suction head is always close to the sediment layer for efficient sand suction. The high-pressure jet pump sprays high-speed water flow to impact the underwater sediment layer, making the sand and sediment splash and suspend around the sand suction head, and then the jet suction sand pump sucks the suspended sand-silt mixture into the pump body through the straight-arm suction pipe. It can stably extract sand, silt, and small-grain gravel, adapt to various water depths (adjustable via the straight-arm device, matching the 12-inch straight-Arm jet suction dredger’s draft), and has strong anti-clogging performance to avoid blockage by large debris. The 12-inch-specific jet suction sand pump has high lift, large sand suction flow, strong wear resistance and corrosion resistance, ensuring long-term stable operation under complex sediment conditions, with sand suction efficiency and flow rate perfectly matched to the vessel’s scale and dredging needs[2].(12-Inch Straight-Arm Jet Suction Dredger)
