Operating Instructions
To maximize the service life and working efficiency of the 10-inch three-pile dredger, operators must follow standardized operating specifications formulated by our factory. This set of operating guidelines applies to all models of our three-pile dredging boats, covering pre-operation inspection, formal dredging work and daily shutdown procedures.
1. Pre-Operation Inspection
-
Check the overall integrity of the hull, weld joints and anti-corrosion coating to ensure there is no water leakage or structural damage to the dredger.
-
Inspect the hydraulic three-pile positioning system, test the lifting and lowering functions of positioning piles, and eliminate jamming and abnormal noise faults in advance.
-
Examine the 10-inch dredging pump, impeller and conveying pipeline of the dredging boat, confirm that all wearing parts are installed firmly without looseness or blockage.
-
Detect the operating status of the high-power power system, check fuel reserve, circuit and oil circuit tightness to avoid power failure during continuous high-load dredging operation.
-
Debug the intelligent control panel to verify that all monitoring data indicators can be displayed normally and accurately.
2. Formal Operation Steps
-
Move the dredger to the designated working water area, adjust the hull position horizontally, and slowly lower the three positioning piles to fix the hull steadily on the water surface.
-
Start the power device at a low speed, preheat the 10-inch dredging pump for 3-5 minutes, and gradually increase the power to the rated working parameter range.
-
Adjust the stirring depth and suction angle according to underwater sediment thickness to start formal desilting and dredging work; do not start the pump under overload conditions for a long time.
-
During operation, observe real-time data of flow rate and pump pressure through the control system. If pipeline blockage or abnormal vibration occurs, reduce power immediately and troubleshoot the fault.
-
After completing the dredging task of a single fixed point, retract the positioning piles slowly, adjust the hull to the next working area, and repeat the above operation process.
3. Shutdown Procedures
-
Before shutting down the dredging boat, suspend sediment suction first, keep the 10-inch dredging pump running with clean water for 5-10 minutes to flush residual sludge and sand inside the pipeline and pump body.
-
Reduce the engine power gradually to idle speed, then turn off the power system, and retract all positioning piles to the designated fixed position.
-
Carry out preliminary cleaning of the hull surface and wearing parts, and record the operating data and abnormal problems of the dredger for later maintenance.
4. Basic Operational Skills & Practical Guidance
To help operators master the 10-inch three-pile dredger faster and improve overall construction efficiency, our factory sorts out exclusive practical operation skills for this type of dredging boat, covering sediment suction adjustment, hull auxiliary control and daily efficient operation methods, suitable for all working scenarios of large-scale dredging equipment.
-
Sediment Suction Adjustment: When working in areas with low sediment concentration, appropriately reduce the lifting height of the stirring device and increase the pump power within the rated range to enhance suction force. For thick and viscous sludge areas, operate the stirring device to reciprocate horizontally, which can effectively avoid suction interruption of the 10-inch dredging pump and improve the overall working efficiency of the dredger.
-
Horizontal Hull Fine-Tuning: When the single-point dredging area cannot meet the construction demand, there is no need to fully retract all positioning piles. Appropriately lift one or two piles, and use the residual friction of the positioning piles to slowly push the dredging boat to move horizontally, which saves adjusting time compared with full retraction and repositioning.
-
Water Depth Adaptation Operation: In shallow water areas with a draft below 1.2m, reduce the running speed of the stirring device to prevent the stirring impeller from touching the riverbed and damaging the hull structure. In deep water areas close to the maximum dredging depth, keep the three positioning piles vertical to share the hull pressure and ensure stable operation of the dredger.
-
Dual Power Switching Tips: For dual-power configured dredging boats, switch power modes during idle downtime instead of during dredging operation. After switching power, run the equipment at idle speed for 2-3 minutes to stabilize the internal pressure of the 10-inch dredging pump, preventing sudden pressure changes from causing pipeline cracks.
5. Pipeline Blockage Emergency Solution
Pipeline blockage is the most common minor fault during the operation of three-pile dredgers. Operators can follow the below standardized solutions to quickly eliminate faults without damaging the wearing parts of the dredging boat:
-
Once blockage occurs, immediately stop sediment suction and reduce the engine to idle speed, keep the 10-inch dredging pump running with clean water to dilute the blocked sediment inside the pipeline.
-
If the blockage cannot be removed by water flushing, reverse the pump for 10-20 seconds repeatedly. This method is developed by our factory for 10-inch dredger series to discharge blocked gravel and massive sludge from the suction port.
-
For severe blockage that cannot be solved by the above methods, cut off the power completely, disassemble the quick-disassembly connector of the conveying pipeline, manually clean the internal blockage, and reassemble the pipeline for trial operation after cleaning.
Important Notes & Safety Precautions
Professional safety precautions are essential for long-term stable operation of the 10-inch three-pile dredger. Our factory summarizes targeted risk control rules for daily operation, maintenance and storage of the dredging boat to reduce potential safety hazards and failure rates.
1. Operational Safety Notes
-
Operators must receive professional operation training provided by our factory before taking post; untrained personnel are prohibited from independently operating the dredger to avoid equipment damage and safety accidents.
-
It is forbidden to operate the dredging boat in extreme weather such as heavy rain, strong wind, thunderstorm and huge waves, so as to prevent hull tilting and capsizing accidents.
-
Do not adjust the positioning piles or disassemble the conveying pipeline when the dredger is in full-load operating state; all adjustment operations need to be carried out after power-off and shutdown.
-
The dredging depth shall not exceed the maximum rated parameter of the equipment, and overload operation is strictly prohibited to prevent burnout of the 10-inch dredging pump and power motor.
-
Keep a safe distance from floating debris, underwater rocks and aquatic plants during operation to prevent the stirring device and pump body from being entangled and damaged.
2. Daily Maintenance Precautions
-
After daily work, clean the sludge inside the pipeline and pump body of the dredger in time to prevent sediment from solidifying and causing pipeline blockage.
-
Regularly add high-grade lubricating oil to the hydraulic positioning system and rotating parts of the dredging boat, and replace worn sealing accessories regularly according to the operating frequency.
-
Check the anti-corrosion coating of the hull and positioning piles every month, and repair the peeling coating in time to avoid metal corrosion and shorten the equipment service life.
-
For long-term idle dredgers, drain the residual water inside the pump body and pipeline, park the equipment in a dry and ventilated dock, and cover it with dustproof protective cover.
3. Fault Handling Precautions
-
Once the equipment has abnormal noise, sharp vibration and pipeline blockage during operation, cut off the power immediately to stop working; forbidden to disassemble parts with electricity to eliminate faults.
-
For core faults such as 10-inch pump body damage and hydraulic system failure, please contact the after-sales team of Qingzhou Yakai Dredging Machinery Manufacturing Co., Ltd. in time; do not disassemble privately without authorization, otherwise the warranty service will be invalid.
-
Replace original factory matching accessories provided by ourfactory for damaged parts of the dredging boat; mismatched accessories will cause irreversible damage to the whole machine.
