Product DescriptionProduct DescriptionWhat is Dredging and Mining Equipment-Jet Suction Dredger? Type: The dredger is made of marine steel construction, self-propelled or non self-propelled with dismountable type.Structure: The dredger is consisted with three pontoons, one main pontoon (engine room with diesel engines, dredging pump, generator and hydraulic system etc.), and two side pontoons.Size: All parts are dimensioned to allow the dredger to be transported by truck.Connection: The dredger is equipped with a rapid connection-disconnection system for the pontoons, the deck is fastened with bolts, and the front and rear bottoms of the hull are reinforced with hooks.Power: The dredger is powered by one main diesel engine and one auxiliary engine, and the main diesel engine drives the dredging pump and the auxiliary engine drives hydraulic system.Features of Jet Suction Dredger1-Module box structure, easy to dismantle and assemble at working site2-Work capacity could be 8000m3/h3-Dredging depth could be 20 meters4-International famous brand engine, multiple options are available for selection 5-International famous brand China Shijiazhuang pump6-Siemens PLC control system7-Rexroth hydraulic valves and system8-Eaton Vickers hydraulic pump9-Can be operated remotely in the operation room, with good all around visibility10-Full tested in factory before delivery11-Short production time12-Corrosion resistant painting and anti-corrosion zinc block13-Safety and rescue equipmentTechnical SpecificationsDredging equipment jet suction dredger technical specificationModelJUNHANG-JSD150 (6 inch)JUNHANG-JSD200 (8 inch)JUNHANG-JSD250 (10 inch)JUNHANG-JSD300(12 inch)JUNHANG-JSD350(14 inch)JUNHANG-JSD400(16 inch)Overalllength15.0m15.8m22.0m24.0m26.0m28.0mHull length11.0m12.0m16.0m19.0m19.0m19.0mHull width3.5m3.5m6.2m6.2m7.5m7.5mHull depth1.5m1.5m1.5m1.9m2.0m2.2mWater flow550m3/h800m3/h1000m3/h1500m3/h2000m3/h2500m3/hSolid sandcapacity110m3/h160m3/h200m3/h300m3/h400m3/h500m3/hDredgingdepth5m6m9m10m12m13mDischargedistance600m800m1000m1200m1500m1500mDraught1.0m1.1m1.2m1.3m1.5m1.6mSuctionDia.200mm250mm300mm350mm400mm450mmDischargeDia.150mm200mm250mm300mm350mm400mmEnginepower160KW280KW480KW720KW924KW970KWWire ropepulling force (lifting winch ) * quantity20KN * 120KN * 130KN * 140KN * 180KN * 180KN * 1Wire ropepulling force (traversing winch ) * quantity20KN * 220KN * 230KN * 240KN * 280KN * 280KN * 2ApplicationWidely used in sand-excavating fromsea, lake, port, pond, coastal, river dredging, channel maintenance andbroaden, desilting, reclamation for channels and land, port deepening and constructionetc.Important Core Component DescriptionDredger HullThe dredger hull is with dismantled type and box-like structure, consist by 1pc middle pontoon and 2pcs side pontoons, in order to transport convenient by truck, easy installation at working site. And it is sandblasted and painted by 4 layers of marine epoxy paint suitable for saltwater service. The zinc anode can be used to give better anti-corrosion function. All dredgers are made of special marine steel plates, which have been certified by CCS.Marine Diesel EngineInternational famous brand engine, multiple options are available for selection1. Large power, low consumption;2. Run steady, marine diesel engine with seawater and fresh water heat exchanger;3. With gearbox to adjust the speed;4. Main engine and auxiliary engine collaborative;5. Located in engine room, enough space for maintenance.Dredge pump1. High efficiency; reasonable design of lubricating and cooling system; running temperature is low;2. Alloy impeller, the flow-parts of pump are corrosion resistance;3. The bearing box is with good sealing;4. Easy disassembly and energy saving;5. Run smoothly, low vibration, large flow regulation range;6. Large transportation ability.Controlling systemWe use PLC Siemens controlling system. The dredger through the PLC system to control the hydraulic transmission device, including cutter, winch, hydraulic cylinder etc.Operation console is set in the operation room, and the operation of all equipments of the dredger can be remotely controlled in the operation room. Packaging & ShippingFactory shipment and transportationPort dredger loading, transported by bulk carriersEach dredger is detachable structure to facilitate truck transportation on land. Depending on the size, some models of dredgers can be disassembled and transported through containers, some models can be disassembled and transported through bulk carriers. Simple disassembly and fast installation.Each dredger is detachable structure to facilitate transportation on the sea and land.Quality GuaranteeHow to control the quality of jet suction dredgers?Testing before shipment in testing poolTo ensure the good performance and safety, each ship must undergo complete test before leaving the factory, and it is tested like the machine working in the customer's working site. There will be test records during the testing process of dredging performance and safety. After testing, the dredger is sent to the customer's work site for installation and can be directly put into use. Usually, the customer can supervise on site during the dredger testing period. Including: -Condition of electricity connection-Operation conditions of hydraulic system-Engines running and power capacity-Mechanical dredging work-Dredging pump rotates at different speed with fresh waterDredger Test Certificate by CCSRegarding After-sales ServiceWhat kind of dredger service guarantee is provided?After-Sales Service-installation, commissioning and training:*After delivery, we send experienced engineers who will be to guide the installation of dredger and train the operators.*Dredger will be tested for running 24 hours after the complete installation. Dredger test includes:Operation of the sand /mud dredging, Hydraulic and electrical system operating, Running of the dredger's outfitting equipment* Our engineers will provide technical training on dredger for customers' workers, how to operate the dredger and daily maintain the dredger until the workers learn it. After-Sales Service-warranty and maintenance:*We provide free warranty and on-site maintenance service for a period of one year after commissioning.*24/7 technical support standby. If customer's dredging experience unskilled, equipment failure or customer needs to solve the dredger small problem, we will send our engineers to customer's working site to inspect and repair at any time.
